Thanks for the query.
You are having unexplained infertility
Unexplained infertility is infertilityin 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 clomiphene citrate and performance of intrauterine insemination
(IUI) 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.
