Hi,
1. Please do not panic.
2.
Retroverted uterus as such or alone need not be the cause of
infertility. As you were advised by your treating doctor to avoid certain foods, she must be thinking of poly cystic ovaries, this condition can also interfere with conception.
3. Also, you can undergo ovulation study on
sonography and get IUI - intra uterine insemination done, on the day of ovulation. This will help to overcome retroverted uterus issue.
4. Secondly, you need to rule out
pelvic infection, as a cause of your pain after sex act. Please seek your doctor's advice for suitable antibiotic.
5. Lastly, about your orgasm issue - Please learn to be calm and quiet during sex act, focus on pleasure points and areas. Be frank with your partner. Ask him to pleasure you at areas where you want him to stimulate you.You need to learn to get orgasm.
6. Please do not worry. If needed, HSG - hystero salpingography after menses can be done to know about patency of your tubes.
Semen analysis of your partner can be done if needed.
I hope this answer helps you. Let me know if I can assist you further.
Thanks,
Dr. Purushottam Neurgaonkar
