Dear Madam,
All the tests done on both of you are normal. By this statement, I presume that you are releasing the egg normally, your both the tubes are patent, the uterine lining is normal and there is no tumour or any abnormality in the
uterus. Also that there is no infection in the vagina. Further more I understand that the semen examination of your husband has revealed normal
sperm count with normal motility.
In such case, I would suggest you to go for ovulation monitoring. You will have to submit yourself for
ultrasonography from day 9 onwards till the ovulation (egg release) takes place. Usually the ovulation occurs when the follicle of the egg attains the size of 18 mm. Utilize this day , a day before and after this. Plan your sexual intercourse on these days. If there is no other abnormality, this should make you happy.
If the ovulation takes place after the follicle attains more than 21 mm size, the chances of fertilization are very poor.
May I suggest you one more test, if you have not done it already. Please get the post-coital semen examination done. In this test, semen is collected from your vagina after the intercourse for microscopic examination.
Some times, the vagina contains
antibodies or environment which is hostile to the sperms. In such cases, the sperms which were normal in semen examination, show dead or sluggish in this test. Thus this test reveals whether your intravaginal environment is hostile to your husband's semen or you have got antibodies against his sperms which is preventing factor for the fertilization. If it is so, you may ask me direct question by going to my profile and upload the reports for my review so that I can advise you some measures.
I hope this much advice should give you some direction.
