Hello all! I actually have TWO sets of twins - both fraternal (b/g). My children are 9 year old single, 4 1/2 year old twins and 21 month old twins. I have done LOTS of research on the topic. Here is what I have learned:o There are actually three types of twins: 1) Identical which are 1 egg, 1 sperm - which splits; 2) fraternal which are two eggs, two sperm; and 3) which I can't remember medical term, but are one egg which splits then is fertilized by 2 sperm. These can be very similar to identical or can be opposite sex since the dad determines the sex. They are now saying the Olsen twins are not identical!! o Twins in the same sac are ALWAYS identical, twins in separate sac can be either type. It depends on how early the split occurs in identicals - if it is early enough - they will have two sacs. o Identical twins are not supposed to be hereditary, but my friend has 8 sets of identical twins in her family. It makes sense to me that if a woman has the propensity to drop more than one egg, she might also have the propensity to have her eggs split also. o It is supposed to be passed along ONLY from woman to woman ... since it is the eggs that determine twins, the father has NOTHING to do with it (except for the obvious, he, he) o When you are over 35 (which I was both times - 37 first time; 39 second) you have a higher chance of twins. The older you are, the more likely you are to drop more than one egg - to "get rid" of your supply before you start entering pari-menopause (which I am in). I was even on the pill when I got preggers with the second set of twins - I thought I was done - guess not!! o Once you have fraternal twins - without fertility help - you have a 40% chance of doing it again. Once you have done it twice, you have about 80% or higher chance of doing it again (which is why I am fixed - he, he) Anyway - that is all I can think of now - if anyone wants to chat - please email me! Hectic Mom of Five!!
