<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hello doctor...I am undergoing follicular study presently...today was my second sitting...the results of first sitting are...on 8th day of cycle... Right ovary 19 14 mm 13 10 mm Left ovary 12 10 mm Thickness 3.8 Type 2 Second sitting...on 10th day Right ovary 25 18 mm 1615 mm ...RI 0.65 Left ovary 15 14 mm Thickness 4 Type 2  <response>: Ideally when the follicle is around 18-20 mm and on the 13th or 14th daytakingnyour menstrual cycles of 28 days, the follicle should rupture. The ruptured follicle would release the egg which would meet the sperm and result in conception. Secondly the thickness uterine winning should ideally be 8-10 mm for the pregnancy to attach itself. You should ask your doctor to advice you Chat Doctor injections to facilitate the rupture of egg if it doesnt rupture by the 18th day. Similarly he will advise you injections to improve the uterine thickness. In case the follicle doesnt rupture or decrease in size in subsequent scans i advice you a pelvic ultrasound as soon as you finish with your next periods to rule out the formation of cyst as sometimes ovarian cysts can be misdiagnosed as follicles or over mature follicles can become cysts.
