Dear patient!
You have not mentioned:
1. Follicular development on days 14, 15, 16
2. Tubal patency tests
Have you attempted:
1. Intra Uterine Insemination (IUI)
2. Invitro Fertilization (IVF)
If every thing is normal, the following may be the reasons for failure to conceive:
1. Anti-sperm anti-bodies in the cervical secretions
2. Unexplained infertility
If you have tried IUI and/or IVF, the presence of anti-sperm anti-bodies in the
cervix is bypassed.
Anyhow, you are not alone in facing this dilemma. There are many couples complaining of the same problem. And many conceive eventually. So, please don't lose hope and stay positive.
Still, you must go to your doctor and check for the above said reasons.
1. Tubal patency
2. Follicular development
3. Anti-sperm anti-bodies in the cervical secretions
Hope this has been helpful.
Awaiting your precious feedback.
