My wife, age 34, has her mensuration cycle on time and so does the ovulation as well. We are married for 6 years during which she suffered 2 miscarriages. 4 months ago after hsg it was found that her one of the fallopian tube was block and some infection was found and doctor started treating for the same with medicines used for intestine tb. Even after treatment was started the ovulation was on time. But this month when ovulation study was done it was found that eggs were not made. Is it because of the medicines she is taking or what can be the possible cause? Is it severe? please suggest.
