My husbands parents were very fertile. producing nine children. does that mean my husband is very fertile as well since his parents were?

Growing a family: Your inlays having been fortunate enough to raise a large family may inspire your husband to want a large family. What is more relevant is the ability of you both, as a couple, to have children. Fertility likely has an inherited component, but I would not depend on it.

Not necessarily: The ability to father children is something most men achieve after puberty. Those that embrace the idea of a big family and have a willing partner will do so. That doesn't mean your spouse is more fertile than other men, just aware that big families can work.He could have acquired a problem that would limit his ability.
