I think the situation is slightly amusing!!
So if the sperm is not strong enough they can give medicine for that?
So what if they find the sperm is ok...and the female partner has had her tests as well as she is given the green signal as well...and they still arent conceiving? what would/could be the reason for that?
actually its not quite possible that both their tests are normal then. there is definitely a prob in either one of the spouse due to which they are unable to conceive. it can be hormonal, PCOS for women and sperm count etc for men. havin said that, i believe in fate too... so if Allah wills, even if both of them are fertile, they mite still find it difficult to get preg.
