Hello Thanks for the query. You should have consulted a proper infertility specialist by now, I hope you have. the phenomenon that you mention is entirely normal. It is very natural for some seminal fluid to get discharged, however, for fertilization, please remember that only a handful of sperms are required. If she doesnt immediately get up after intercourse, the necessary amount has already entered the vaginal and cervical canal. ALso, please make sure the basic laboratory tests, necessary hormonal tests, sperm counts, fallopian tube testing etc has been done. Sometimes, there is a condition called unexplained infertility, for which you should not give up, but keep trying the avenues of ART ( assisted reproductive technology ) under guidance of a Specialist Infertility practitioner. Take care.
