[/INST] HelloHowever, there may be many reasons of INFERTILITY in male and female. In male azoopermia (oligospermia) is one of the most common reason and I have seen that this problem is a hereditary problem, but it is not scientifically proven. This may be the reason of delayed conception for your mother-in-law. Same reason may be in your case also, but before any judgement your husband must be examined for SEMEN analysis. You should get an ultrasound of Fallopian tube, uterus and also hormonal test for yourself. Get in complete fertility test and thereafter deal accordingly. Hope you will get good result. </s>
