Please advice as i have visited doctor also.  <response>: Hello, Thanks for the query. You are having unexplained infertility. Unexplained infertility is infertility in which cause remains unknown even after an infertility work-up, usually including semen analysis in the man and assessment of ovulation and fallopian tubes in the woman. Incidence being 20 among infertile couples. The most efficient management of unexplained infertility appears to be administration of camphene citrate and performance of intrauterine insemination GUI during 3 menstrual cycles, And if this has not resulted in pregnancy, then go for in vitro fertilization IVF in 6 menstrual cycles. Wish you good luck. Regards, Chat Doctor.
