What do you suggest if my husband had 3 hernia surgery is it possible we could ever have children?

Possibly: In good hands, a hernia surgery has no negative effect on a males potential for reproduction. Even after 3 surgeries, this should be no problem.

Yes.: Why are you concerned about the hernia history? You are apparently age 45. You may need in vitro fertilization; please see a reproductive endocrinologist, as your age is your primary factor for worry with regard to having a pregnancy.
