Infertility has not been proven hereditary, but there are some cases where you can find members but not close of the same family having the same problem.
Indeed, it is the case for me and my cousin, there is no direct realtion but then we are both following a treatment for fertility with
clomid whch we order generally from
CLOMID (CLOMIPHENE) (GONAPHENE) for about 3 month now. We just recently heard that another cousin living in france is suffering from the same condition. Maybe that is not hereditary but the it might be possible that the problem comes from the blood line as we all 3 come from the same grand-mother. Hope there may be some search in that domain.
