Hi Geeta, Tab Folvite contains folic acid. It is one of the B vitamin. It should be taken by all women who are planning for pregnancy. This vitamin to a large extent prevents the development of some spinal cord birth defects in the baby. This is the reason your doctor has given it to you. It has no action on your fertility. it does not help you to get pregnant. What is your age and BMI? How long have you been married? Are your menstrual cycles regular? From your notes I understand that your hormone tests and fallopian tube patency tests are normal and your husband s semen analysis is normal. Then this is unexplained infertility. In this case try regular intercourse ( at least thrice in a week) for two years. If you are already practicing regular intercourse for two years or more you need to see infertility specialist. Depending on your age the doctor will discuss with you induction of ovulation with hormones for three to six cycles or IUI for three to six cycles. If this does not help then IVF may be considered. I hope I have answered to your satisfaction.
