Find out if giving birth to twins runs in the family

The minute someone mentions having twins, most people instantly react by asking ‘do twins run in your family?’ It’s normal to ask that question because usually twins do run in the family, but is it always the case? The answer to this age-old hereditary question isn’t really a solid yes.


Giving birth to twins does run in the family but only for non-identical or fraternal twins. Non-identical twins are usually inherited from the mother’s side. This is usually caused by hyperovulation which causes a female to release several eggs at once during ovulation. If one female in the family has this genetic tendency, she can transfer it to her daughter and possibly even her grand-daughter. If the female has no daughters, it can skip a generation and resume in the next generation of females.


Giving birth to identical twins does not run in the family and can just happen randomly as well. Identical twins are a result of split fertilized egg. Science does not really have an explanation for this but some just call it good luck or a mere coincidence.


Giving birth to twins can also happen if you use drugs to increase your chances of having a baby. It seems that taking fertility drugs or treatments can help women conceive twins and even multiples. Aside from this, it seems that age also plays a factor in increasing chances of having twins. Once a woman has hit 30, her body tends to produce stimulating hormones that aid in ovulation and increases chances of egg spitting. This is why a woman who conceives at an older age is most likely to produce twins.
