My friend (30) and I (32) are still discussing whether we will try to have children. Now he’s half identical twins, but so am I. We’d like to have one if we’re already having kids, but the fact that we’re both half identical twins increases the chances of having multiples, or doesn’t it matter and we might as well have singletons ?
Answer
Dear Diana,
the trait of having multiple ovulations (ovulation) per cycle is hereditary, making dizygotic or fraternal twins more common in certain families. Identical twins are a freak of nature, pure coincidence, and there is currently nothing affecting their prevalence (except hormonal stimulation and medically assisted fertilization to a very slight extent). Therefore, the fact that both you and your partner are members of identical twins does not increase your chances of conceiving twins. You run the same risk as loners.
