To compare the effect of different formulations of continuous combined hormone therapy on sexual performance in naturally postmenopausal women.
                A total of 158 postmenopausal women were enrolled and prospectively randomized to the single-blind study. Fifty-four women received tibolone 2.5 mg, 53 received 2 mg estradiol and 2 mg dienogest (E2/dienogest), and 51 did not receive any menopausal therapy. The patients were monitored after 6 months. Attitudes of sexuality were evaluated by using the Rosen's female sexual function index.
                Compared with E2/dienogest and the control group, tibolone treatment was associated with more improvement of sexual performance, including sexual desire, sexual arousal and satisfaction. Both of the hormone therapies decreased frequencies of vaginal dryness and painful intercourse.
                Tibolone has more positive effects on the sexual dysfunction of postmenopausal women and may be an alternative to the E2/dienogest preparation in postmenopausal women with sexual dysfunction. To compare the effects of two different postmenopausal regimens on sexual performance.
                A single blind prospective clinical study was planned on fifty natural postmenopausal women with no absolute contraindication for hormone replacement therapy (HRT). A total of 25 women were randomized for tibolone therapy (group T) and the rest 25 for continuous conjugated estrogen (CE) 0. 625 mg plus medroxyprogesterone acetate (MPA) 2.5 mg (group E) for a year. Two women in group T and four women in group E were excluded from the study as they didn't attend the control visit. At baseline and after a year, sexual performance parameters (sexual desire, coital frequency, orgasm frequency, vaginal dryness/dyspareunia) and after therapy subjective well-being, vasomotor symptoms, and side effects were assessed by score method designed by us.
                Treatment with either preparation significantly improved subjective well-being, vasomotor symptoms and vaginal dryness. The rates of overall side effects between two groups were not found statistically different (P=0.84). Tibolone therapy increased sexual desire and coital frequency (P=0.001, P=0.014).
                Both tibolone and continuous combined CE/MPA effectively improve the findings of hypoestrogenism and subjective well being. Moreover, tibolone effectively increases sexual performance. It is seen that tibolone with acceptable androgenic side effects can be an appropriate selection for HRT in postmenopausal women with decreased sexual desire. To evaluate the benefits and risks of hormone replacement therapy (HRT) combined with methyltestosterone (MT) in postmenopausal women with sexual dysfunction.
                This study was a randomized, double-blind, placebo-controlled and crossover trial. Eighty-five women using HRT were divided into four treatment groups: GI-HRT plus placebo for 4 months; GII-HRT plus MT 2.5mg/day for 4 months; GIII-HRT plus placebo for 2 months and then replaced with HRT plus MT 2.5mg/day for 2 months; GIV-HRT plus MT 2.5mg/day and then replaced with HRT plus placebo for 2 months. Blood was collected at baseline, after 2 months (T1) and 4 months (T2) of treatment for hormone determinations of estradiol, FSH, total and free testosterone, GOT, GPT, glucose, total and fractions of cholesterol and triglycerides. All participants answered clinical questions and a validated questionnaire of modified McCoy's sex scale.
                The association of HRT with MT 2.5mg/day did not significantly change liver enzymes or increase cardiovascular risk factors. The patients of GII, GIIII and GIV when using MT presented amelioration of sex symptoms, mainly satisfaction and desire (p<0.01); however, GIII at T1 (1.3+/-0.3) presented similar problem score results as compared to GIII at T2 (1.5+/-0.6).
                All data suggest that combined HRT-androgen therapy may be beneficial for postmenopausal women receiving HRT who continue to complain of sexual difficulties or for postmenopausal women with sexual complaints who are not undergoing estrogen therapy. Most previous studies designed to evaluate the efficacy of hormone replacement therapy (HRT) have been carried out in Europe, North America and Australia, involving Caucasian women for 6 months or less.
                To evaluate the 12-month effects of two different HRT regimens on postmenopausal symptoms of Middle-Eastern women.
                Hundred healthy Libyan women with postmenopausal symptoms, 12 months or more since their last menstrual period, were enrolled in a 12-month prospective study. Participants were randomly prescribed one of the two formulations, 50 in each group. These regimens were a continuous regimen of tibolone 2.5 mg oral tablets and a continuous regimen of 17beta-oestradiol sequentially combined with dydrogesterone (2/10 mg) oral tablets. The presence and severity of short- and intermediate-term symptoms were reported at 0, 3, 6 and 12 months of treatment. Observed symptoms were hot flushes, night sweating, palpitations, insomnia, depression, nervousness, loss of memory, vaginal dryness, loss of libido and joint pain.
                Forty-nine women (98%) in each group completed the 12-month study period. Participants, in the two groups, experienced a significant improvement within the first 3 months of treatment. The observed symptoms were completely relived by the sixth month without any significant difference between the two groups. Improvements were sustained over the 12-month period of the study. HRT users showed their acceptance to the two regimens.
                Tibolone and 17beta-oestradiol/dydrogesterone oral tablets were effective and safe to treat short- and intermediate-term symptoms in Middle-Eastern postmenopausal women, within 6 months, and with no significant differences between the groups. Thus, the use of HRT to relieve menopausal symptoms is highly recommended, at least in this region. The goal of this study was to investigate the effects of hormone replacement therapy (HRT) and tibolone on the sexuality and quality of life of Taiwanese postmenopausal women.
                Forty-eight postmenopausal women were enrolled and prospectively randomized to receive either HRT or tibolone for 3 months. At the end of the 3-month period, quality of life measures were assessed using the Greene Climacteric Scale and attitudes of sexuality were evaluated using the McCoy Sex Scale.
                Based on subjective qualitative scores, tibolone treatment was at least as effective as continuous combined HRT in improving quality of life. It also effectively prevented withdrawal bleeding, which may occur during HRT use. Compared with continuous combined HRT, tibolone treatment was also associated with perceived improvement of sexual performance, including general sexual satisfaction, sexual interest, sexual fantasies, sexual arousal and orgasm, with decreased frequencies of vaginal dryness and painful intercourse.
                The findings of this study indicate that both tibolone and continuous combined HRT have positive effects on the quality of life of Taiwanese postmenopausal women. Sexuality is affected more by tibolone than by HRT. To compare the effects of tibolone with those of conventional hormone replacement therapy on climacteric symptoms and sexual function in postmenopausal women.
                In a randomized, controlled trial, 140 postmenopausal women were allocated into three groups. Of the subjects included, 47 women received 2.5 mg tibolone + one Cal+D tablet (500 mg calcium and 200 IU vitamin D) daily; 46 women received 0.625 mg conjugated equine estrogen + 2.5 mg medroxyprogesterone (CEE/MPA) + one Cal+D tablet daily; and 47 women received only one Cal+D tablet as the control group. The Greene Climacteric Scale (GCS) questionnaire was used to detect the efficacy of treatment on climacteric symptoms. Rosen's Female Sexual Function Index (FSFI) was used for sexual function evaluation. Sex hormone binding globulin (SHBG), free estradiol index (FEI) and free testosterone index (FTI) were measured before and after treatment. The women were followed up for 6 months
                After treatment, all subscores in the GCS improved in the tibolone and CEE/MPA groups (p < 0.01), except the sexual subscore in the CEE/MPA group, compared with baseline. There were significant differences in the FSFI in the tibolone and CEE/MPA groups in comparison to the control group after treatment. Tibolone, in comparison to CEE/MPA, significantly lowered SHBG levels and increased the FTI and FEI and improved the desire, arousal and orgasm sexual domains of the FSFI (p < 0.001).
                Tibolone may be an alternative to conventional hormone replacement therapy in the treatment of climacteric symptoms and sexual dysfunction in postmenopausal women. To compare compliance, symptom control, bleeding patterns, lipid and biochemical changes in postmenopausal women treated with three regimens of HRT.
                In a prospective, randomised, group comparative study, with 165 patients, the effects on the aforementioned parameters, as well as treatment compliance and side effects were studied with oral tibolone 2.5 mg per day, with cyclic combined regimen of transdermal oestrogen and progestogen (transdermal patch of 17beta-oestradiol 50 microg/day during 14 days and transdermal patch of 17beta-oestradiol 50 microg/day plus 0.25 mg/day NETA during the following 14 days), and with intermittent progesterone regimen (transdermal 17beta-oestradiol 50 microg/day and oral micronised natural progesterone 200 mg twice a week). Statistical analysis was carried out using the Fisher-test, analysis of the variance (ANOVA) and the Bouferoni test.
                Ten women dropped out of the tibolone group, 11 dropped out of the intermittent dosing group and 21 dropped out of the cyclid combined group. Irregular bleeding occurred at more rates in the cyclid combined group. Similar reductions in climacteric symptoms were found in the three groups. No differences were observed with respect to biochemical analysis.
                Efficacy and safety of the three treatment regimens being comparable, but the patients in our study preferred those that did not produce bleeding episodes. To compare relief of vasomotor symptoms, changes in lipoproteins, and bleeding patterns in postmenopausal women receiving either continuous combined hormone replacement therapy (HRT) of estradiol valerate and norethisterone or tibolone 2.5 mg/day.
                In a multicenter, randomized, open-label study, 235 postmenopausal women received one of the above-mentioned treatments. Fasting lipoproteins were measured at baseline and at 3, 6, and 12 months. At each visit, participants completed Greene climacteric questionnaires and recorded any bleeding episodes. Data are presented as mean +/- standard deviation if normally distributed, median and interquartile range if non-normally distributed, or as frequency count. For menopausal symptoms and diary card data, the differences were tested by Wilcoxon rank-sum test.
                One hundred sixteen women received continuous combined HRT and 119 women received tibolone; 72 and 76 women, respectively, completed 12 months of therapy. Both treatments effectively relieved vasomotor symptoms and reduced serum total cholesterol. Continuous combined HRT, but not tibolone, significantly reduced low-density lipoprotein levels. Both treatments reduced high-density lipoprotein levels, but the effect was more profound with tibolone. The initial bleeding score was higher for women taking continuous combined HRT; however, by the end of the study, the percentages of amenorrheal women were comparable. Endometrial histology was similar for both treatments at the end of the study, although two cases of proliferative endometrium were found in the tibolone group.
                Estradiol valerate-norethisterone continuous combined HRT controls symptoms and is associated with a safe lipid profile. Tibolone has been shown to alleviate climacteric symptoms. This study was designed to compare the effect of tibolone (Livial, 2.5 mg daily) on different climacteric complaints and its impact on the endometrium, determined by vaginal ultrasound, with that of conjugated estrogens (Premarin, 0.625 mg daily) continuously for 6 months in combination with the progestogen medrogestone (Colpron, 2 x 5 mg daily for 12 days each month).
                One hundred and twenty-nine postmenopausal women were recruited and the severity of climacteric symptoms as well as endometrial thickness were recorded at the pre-trial examination and after 1, 3, and 6 months.
                With the exception of vertigo, mood depression, mood disorder, loss of libido, and dryness of skin, where tibolone was found to be more effective than conjugated estrogens/medrogestone, climacteric symptoms improved significantly in both groups over the 6-month study period. Endometrial thickness did not increase significantly in the tibolone group, whereas in the conjugated estrogens/medrogestone group there was a highly significant increase after 1 month and still a trend towards significance after 6 months. Recurrence of vaginal bleeding occurred significantly less frequently in the tibolone group than in the comparison group.
                Tibolone seems to offer a complete treatment of the climacteric complaints whilst avoiding some of the problems associated with classical hormone replacement therapy. This study aimed to evaluate the effects of monophasic estrogen-progestogen therapy on the sexuality and climacteric symptoms of postmenopausal women.
                A prospective, randomised, double-blind, crossover, placebo-controlled, single-centre study was carried out over a total of 12 consecutive months in 40 postmenopausal women with an intact uterus who had no contraindications to hormone therapy. Patients received 17beta-estradiol 2mg in combination with norethisterone acetate 1mg (Cliane) daily for 6 months or one placebo tablet daily for 6 months. The tablets were identical in appearance. After 6 months, the groups were crossed over and the patients were followed up for another 6 months. The groups were homogenous with respect to age, height, bodyweight, body mass index and race. For the statistical analysis, the group receiving hormone therapy was referred to as group A and the placebo group was designated group B, irrespective of the placebo/hormone therapy sequence.
                In group A there were fewer hot flashes (F=22.85, p<0.01) and an improvement in sexual interest (F=5.55, p<0.05). The sequence in which the medication was received resulted in a statistically significant difference with respect to dyspareunia (F=9.65, p<0.01) and satisfaction with the duration of penetration (F=6.58, p<0.05). In the intrapatient analysis of variation with respect to orgasmic capability and the presence of dialogue with partner regarding the couple's sexual life, whether the placebo was taken prior to or following hormone therapy was significant (F=17.12, p<0.001 and F=7.10, p<0.05, respectively).
                Monophasic estrogen-progestogen therapy has a beneficial effect on sexuality and on hot flashes in postmenopausal women. The effect of hormone replacement therapy (HRT) on the quality of life in women with hypertension is still not clear. Thus, the aim of the study was to assess the effect of hormone replacement therapy on quality of life in postmenopausal women with essential hypertension by using a battery of standardized questionnaires.
                The study population consisted of 53 women (mean age 50.9 +/- 6.3 years) with mild and moderate essential hypertension (mean duration 6.4 +/- 6.4 years). The postmenopausal status was defined as the absence of menstrual blood loss during > 6 months and blood estradiol concentration < 50 pg/ml, accompanied by follicle-stimulating hormone (FSH) levels > 21 U/I. Twenty seven women were blindly randomised to transdermal hormone replacement therapy (HRT) and received 17-beta-estradiol and noretisterone acetate, TTS. Twenty six women were randomly selected as controls. The subjects were evaluated at baseline (after 2 weeks' wash-out from hypotensive drug period) and after three months of HRT using self-administered standardized quality of life questionnaires: the Psychological General Well-being Index (PGWB) and the Subjective Symptoms Assessment Profile (SSA-P).
                No differences were found in blood pressure values, heart rate, body mass index and distribution of body fat tissue between women receiving HRT and controls at baseline and after 3 months of follow-up. There were no significant differences in the baseline total PGWB score as well as in its subscale between two groups. Similarly, the frequency and intensity of subjective symptoms assessed by SSA-profile were the same in both groups at baseline. After 3 months, a significant improvement in PGWB total score was observed in women receiving HRT. This effect was due to improvement in anxiety, positive well-being and vitality. Moreover, emotional distress, symptoms of flushing, sweating and trembling hands also diminished and sexual capacity improved in women treated with HRT.
                A three-month hormone replacement therapy in hypertensive postmenopausal women slightly improves the general well-being, seems to decrease emotional tension, increase sexual capacity and markedly relieves some vasomotor symptoms. To investigate the efficacy of esterified estrogens alone and combined with oral androgen on sexual function and menopausal symptoms in postmenopausal women.
                Twenty postmenopausal women dissatisfied with their estrogen or estrogen-progestin therapy volunteered to enter a double-blind, randomized trial in which they received either oral esterified estrogens or esterified estrogens + androgen for eight weeks after a single-blind, placebo, lead-in period. Sexual function was assessed with a questionnaire used in the Yale midlife survey, and plasma levels of estradiol, estrone, sex hormone binding globulin (SHBG) and beta-endorphin were measured at two- to four-week intervals.
                Estrogen-androgen therapy significantly improved sexual sensation and desire after four and eight weeks of double-blind treatment in comparison to previous estrogen therapy and postplacebo baseline assessments. Plasma levels of estradiol and estrone increased significantly in all patients as compared to the postplacebo baseline and decreased in comparison to circulating estrogen concentrations on previous therapy. Relative proportions of free and bound steroid hormone exhibited contrasting shifts during estrogen and estrogen-androgen therapy. SHBG increased in the estrogen group and decreased in the estrogen-androgen group, leading to lower amounts of free androgens during estrogen therapy and increased free androgen levels during estrogen-androgen therapy. Since proportions of free (bioavailable) ovarian steroids would correlate inversely with plasma protein binding capacity, the beneficial effects of oral estrogen-androgen therapy on sexual sensation and desire may be due either to the administered androgen or to the increased availability of endogenous and exogenous androgens, particularly in the central nervous system.
                Sexual desire, satisfaction and frequency in postmenopausal women taking hormonal therapy were improved significantly by combined estrogen-androgen therapy but not by estrogen or estrogen-progestin therapy. Sexual function improved with estrogen-androgen therapy even though circulating estrogen levels were lower than those measured during previous estrogen therapy. This leads to the conclusion that androgens play a pivotal role in sexual function but that estrogens are not a significant factor determining levels of sexual drive and enjoyment. The primary objective was to compare the vaginal bleeding pattern during administration of tibolone and low-dose continuous combined estradiol plus norethisterone acetate (E2/NETA). The secondary objectives were efficacy on vasomotor symptoms and vaginal atrophy.
                A randomised, double-blind, double-dummy, group comparative intervention trial.
                Multicentre study executed in 32 centres in 7 European countries.
                Five hundred and seventy-two healthy symptomatic postmenopausal women, aged 45-65 years.
                Participants were randomised to receive 2.5 mg tibolone or 1 mg 17beta estradiol plus 0.5 mg norethisterone acetate (E2/NETA) daily for 48 weeks.
                Prevalence of vaginal bleeding, hot flushes and adverse events.
                The incidence of bleeding was significantly lower in the tibolone group during the first 3 months of treatment (18.3 versus 33.1%; P < 0.001) when compared with the E2/NETA group. This effect on the bleeding pattern was sustained throughout the study, although reaching statistical significance again only in 7-9 months of treatment (11 versus 19%; P < 0.05). In both treatment groups, vasomotor symptoms and vaginal atrophy were significantly reduced to a similar extent when compared with baseline. The prevalence of breast pain/tenderness was significantly lower with tibolone compared with E2/NETA (3.2 versus 9.8%; P < 0.001).
                Tibolone reduces menopausal symptoms to a similar extent as conventional low-dose continuous combined hormone therapy but causes significant less vaginal bleeding in the first 3 months of treatment. This constitutes an important argument for woman adherence to therapy. To evaluate the effects of combined vaginal and oral low-dose estrogen plus progestogen therapy (EPT) on the frequency and severity of dyspareunia, sexual function, and quality of life in recently postmenopausal women.
                This outpatient, double-blind, randomized, placebo-controlled trial enrolled 285 healthy, sexually active postmenopausal women aged 45 to 65 years. Women received either one daily oral low-dose conjugated estrogens (0.45 mg)/medroxyprogesterone (1.5 mg) tablet for six 28-day cycles along with 1 g conjugated estrogens vaginal cream (0.625 mg), intravaginally for the first 6 weeks of the trial or a placebo cream and placebo tablet. Efficacy was evaluated using the McCoy Female Sexuality Questionnaire, self-reported daily diary cards, the Brief Index of Sexual Functioning-Women (BISF-W), and the Women's Health Questionnaire.
                The EPT group had a significant decrease in the frequency of dyspareunia compared with baseline and placebo in an analysis of responses to the McCoy Female Sexuality Questionnaire. Also, EPT was associated with a significant improvement in a woman's level of sexual interest, frequency of orgasm, and pleasure of orgasm. There was no effect of EPT use on coital frequency. The EPT group had significant improvement in receptivity/initiation and relationship satisfaction, although not in other BISF-W domains, versus placebo (BISF-W analysis) and significant improvement versus placebo on most Women's Health Questionnaire responses.
                EPT provided a statistically significant improvement compared with placebo in dyspareunia, sexual experience, and quality of life as measured in this study. In general, EPT also improved self-reported sexual perception and enjoyment significantly compared with placebo. To evaluate low doses of 17 beta-estradiol (E2) and norethisterone acetate (NETA) as continuous combined hormone replacement therapy (HRT) in their effects on vasomotor symptoms, bleeding episodes, endometrial histology and mastalgia.
                Sixty postmenopausal women were randomly allocated to three treatment groups and were given 1 mg E2 and 0.25 mg NETA (A), 1 mg E2 and 0.5 mg NETA (B) and 2 mg E2 and 1.0 mg NETA (C) in daily doses. The treatment period was 1 year.
                A similar statistically significant reduction of climacteric symptoms (P < 0.05) was found in all groups. Bleedings, mainly as spottings, occurred most commonly during the first treatment months. Fewer bleeding episodes and a higher percentage of amenorrhea was noted in group B compared to the other groups but did not reach statistical significance. All endometrial biopsies showed atrophy. Women in group A and B had less severe mastalgia (P < 0.05) compared to group C, given higher doses of steroids.
                Postmenopausal women taking 1 mg of E2 plus 0.5 mg NETA as continuous combined HRT reported a marked reduction of climacteric complaints and good bleeding control. No endometrial proliferation was detected after 1 year of treatment. This type of therapy may be beneficial especially for elderly women, in whom bleeding may be annoying. To compare the effect of HRT with transdermal estradiol and that of treatment with tibolone in post-menopausal women with residual endometriosis.
                21 women with residual pelvic endometriosis after bilateral oophorectomy with or without hysterectomy were enrolled in the study and were randomized to HRT with transdermal estradiol 50 mg twice weekly (n = 10) associated with cyclic medroxyprogesterone acetate 10 mg daily in women who preserved uterus, and to treatment with tibolone 2.5 mg administered orally once a day (n = 11). The duration of both treatments was scheduled to last at least 12 months. Residual endometriosis was located in the bowel wall in four patients, in the rectovaginal septum in six and deeply in the retroperitoneal pelvic space in six. All women were symptomatic before oophorectomy.
                All the women were followed for 12 months. No patient suspended therapy because of side effects. Four patients of the estradiol group experienced moderate pelvic pain during treatment compared with only one patient in the tibolone group. One patient in the estradiol group reported severe dyspareunia.
                Although our series is very small, it seems that tibolone may be a safe hormonal treatment for post-menopausal women with residual endometriosis. To evaluate the effects of hormone therapy (HT) on cognition and subjective quality of life (QoL) in recently postmenopausal women with cognitive complaints.
                Cognitive Complaints in Early Menopause Trial (COGENT) was a randomized, double-blind, placebo-controlled, multicenter, pilot study of 180 healthy postmenopausal women aged 45 to 55 years, randomly assigned to receive either placebo or conjugated equine estrogen 0.625 mg/medroxyprogesterone acetate 2.5 mg for 4 months. Outcome measures included memory, subjective cognition, QoL, sexuality, and sleep, which were assessed at baseline and month 4.
                The study was terminated before the expected final sample size of 275 due to a decrease in enrollment coinciding with the publication of findings from the Women's Health Initiative. There were no differences between groups on any cognitive or QoL measures, except for an increase in sexual interest and thoughts with HT. Modest negative effects on short- and long-term verbal memory approached significance (p < 0.10). Women with baseline vasomotor symptoms (VMS) showed a decrease in VMS and an improvement in general QoL, but no cognitive benefit vs placebo.
                With the power to detect an effect size of >or=0.45, this study suggests potential modest negative effects on verbal memory that are consistent with previous hormone therapy trials in older women. We examined whether estradiol and norethindrone hormone therapy (HT) prevented decline in delayed verbal recall in older women with normal to mildly impaired memory functioning. This was a 2-year, randomized, double-blind, placebo-controlled trial of 142 women aged 61-87, randomly assigned to receive 1 mg 17-beta estradiol daily and 0.35 mg norethindrone 3 days/week or daily placebo for 2 years. The primary outcome was short-delay verbal recall of the California Verbal Learning Test (CVLT). To look for differences in response to HT by baseline short-delay recall, we examined the primary outcome in participants grouped according to whether their baseline scores were below average for the age group or greater than or equal to this score and according to whether they met criteria for Mild Cognitive Impairment (MCI) or not. 133 women completed 1 year of the trial and 128 completed 2 years. Prespecified covariates in all repeated measures analyses of covariance (RANCOVA) included age, education, APOE epsilon4, and prior HT use. RANCOVA showed no overall significant treatment effects at year 1 or year 2. After testing for an interaction, which was significant (p=0.02), we found that women in the HT group who scored at or above the average showed significantly less decline than the placebo group in short-delay verbal recall after 1 year, p=0.007 and 2 years, p=0.01. No treatment effects were found in women below the average in either year. When grouped according to whether the participant met criteria for MCI, the interaction between treatment group and MCI subgroup was not significant. These results suggest that benefits of estrogen exposure may be limited to those with average to above average scores on the delayed verbal recall. HT dose and formulation may have contributed to these beneficial outcomes. Replication is warranted before recommendations can be made in the clinical setting. The influence of a combined estrogen-progestin regimen (Climodien) on noopsyche, thymopsyche, personality and psychophysiological measures of menopausal syndrome patients was investigated in a double-blind, placebo-controlled, comparative, randomized 3-arm trial phase (Climodien 2/3 = estradiol valerate (CAS 979-32-8) 2 mg + the progestin dienogest (CAS 65928-58-7) 3 mg = regimen A, estradiol valerate 2 mg = regimen EV, and placebo = regimen P) followed by an open-label phase in which all patients received Climodien 2/2 (estradiol valerate 2 mg + dienogest 2 mg) = regimen A*. 49 women (16, 17, 16 valid patients per arm) aged between 46 and 67 years (mean 58, 58, 56 years, respectively) with the diagnoses of insomnia (G 47.0) related to postmenopausal syndrome (N 95.1) were included in the analysis of the double-blind phase. Both the double-blind and the open-label phase lasted 2 months. Noopsychic investigations demonstrated an improvement in associative verbal memory after 2 months of regimen A, which was significant as compared with both baseline and placebo. Regarding visual memory, regimen A* induced an improvement, which was significantly different from the decline in correct reproductions in the Benton Test observed under estradiol. Errors in the Benton Test decreased significantly after regimen A* as compared with regimen EV. These findings suggest that hormone replacement therapy with estradiol, and even more in combination with dienogest, improves verbal and visual memory, which is in line with the improvement in information processing speed and capacity objectified by event-related potentials (ERP). Thymopsychic investigations demonstrated a significant improvement in somatic complaints and trait anxiety after both regimen A and regimen EV as compared with baseline. State anxiety decreased significantly under regimen A* as compared with EV. The Freiburger Personality Inventory showed an improvement in aggressivity after regimen A* as compared with the preceding placebo as well as an improvement in striving after dominancy after both regimen A and regimen EV as compared with pre-treatment, but also after regimen A* as compared with regimen EV. Extraversion increased after 2 months of regimen A as compared to regimen P. Psychophysiological findings including pupillary and skin conductance variables were not significant. To elucidate if percutanous treatment with 10mg testosterone per day could enhance sexuality and psychological well-being in postmenopausal women presenting problems with low libido. Secondary to study the influence on blood lipids, hemoglobin and erythropoietin levels.
                Fifty-three postmenopausal women participated. As a complement to their already on-going HRT, 10mg of a testosterone gel (Testogel, Besins-Iscovesco) or placebo was administered. Treatment continued for three plus three months in a double blind, randomized, crossover design.
                The scores concerning "frequency of sexual activity, orgasm and intercourse", "sexual arousal, fantasies and enjoyment", "satisfaction with orgasms", and "interest in sex" were all significally improved for testosterone addition as compared to placebo both before and after crossover. Testosterone levels increased more than 10-fold during treatment while DHT-levels were more than doubled. Estrogen levels were not affected during the addition of testosterone. Liver enzymes, total cholesterol, triglycerides, HDL and LDL revealed no significant differences between any of the periods or groups. Endometrial thickness did not change significantly during treatment. Hemoglobin and erythropoietin remained unchanged. No significant differences in the number of experienced side effects were found.
                Testosterone gel of 10mg had positive effects on several aspects of sexual life such as frequency of sexual activity, orgasm, arousal, fantasies and sexual interest in postmenopausal women on HRT. Several psychological variables were positively influenced. The given dose resulted in too high serum levels. Even if no negative effects were observed, monitoring of serum levels and a decreased dose should be considered in future studies. To assess the effect of tibolone on endometrial safety, plasma estradiol concentrations, lipid metabolism and climacteric symptoms in comparison to sequential conjugated equine estrogens and medroxyprogesterone acetate in postmenopausal women.
                In a randomised, open-label, 6-cycle, group-comparative study, the effects on the aforementioned parameters were studied with tibolone 2.5 mg/day (N = 13) continuously, and with conjugated equine estrogens 0.625 mg/day continuously, combined with medroxyprogesterone acetate 5 mg/day (N = 11) (CEE/MPA) sequentially, during 12 days of each 28-day cycle. Within-group statistical analysis was performed with Student's t-test for paired samples, whereas between-group statistics were performed using the Student's t-test for independent groups.
                Cytological evaluation revealed no endometrial stimulation in either group. In the tibolone group, there were no effects on estradiol levels, whereas in the CEE/MPA group, an increase in total and non-SHBG-bound estradiol plasma levels was reported. In the tibolone group, there were significant decreases in plasma total cholesterol, triglycerides, HDL-cholesterol and VLDL-cholesterol, whereas no significant changes in LDL-cholesterol and IDL-cholesterol were reported. In the CEE/MPA group there were significant decreases in plasma total cholesterol, HDL-cholesterol and LDL-cholesterol, whereas there were no significant changes in triglycerides, IDL-cholesterol and VLDL-cholesterol. Climacteric symptoms, particularly vasomotor episodes, decreased similarly in both groups.
                Both tibolone and CEE/MPA were safe with respect to effects on the endometrium and both treatments induced changes in the plasma profiles of certain lipid and lipoprotein parameters. However, the overall clinical implications of these changes are unknown. Finally, both regimens were equally effective in the treatment of climacteric symptoms.
HT treatment with estrogens alone or in combination with progestogens was associated with a small to moderate improvement in sexual function, particularly in pain, when used in women with menopausal symptoms or in early postmenopause (within five years of amenorrhoea), but not in unselected postmenopausal women. Evidence regarding other HTs (synthetic steroids and SERMs) is of low quality and we are uncertain of their effect on sexual function. The current evidence does not suggest an important effect of tibolone or of SERMs alone or combined with estrogens on sexual function. More studies evaluating the effect of synthetic steroids, SERMS and the association of SERM + estrogens would improve the quality of the evidence for the effect of these treatments on sexual function in peri and postmenopausal women. Future studies should also evaluate the effect of HT solely among women with sexual complaints.
