Hi LilMirsK - you probably know more than me if you've already done some reading on it, but I would say a definite YES.

My background is in animal reproduction rather than human, but my understanding is that ovulation rate has a genetic component - livestock breeders strive hard to increase the average ovulation rate through selection for the more fertile animals.

Your family history could mean you have a higher than average chance of fraternal twins ie. release of two eggs. In any case, you should have no trouble conceiving with such fertile ancestry.

BTW - Identical twins does not have a genetic component because it's just one of nature's little quirks when a fertilised egg splits early enough to make two separate babies.

I hope you don't mind the comparison to production livestock!!
