Deanna,
nerdy glasses on
PCOS is the leading cause of infertility in women. If you have PCOS, there is a 50% chance your mother, sister and/or daughter have PCOS, and therefore may have infertility problems as well.
I think it probably depends on your cause of infertility, and if it's a health related problem, such as PCOS, then yes, it's hereditery.
This makes me think of a visit we had with an "infertility specialist." DH and I mentioned that there was no history of infertility in either of our families. His response was "Obviously, otherwise you wouldn't be here today!" We did not see him again.
Hope this sheds a little light.
Love,
Julie
