We’ve probably all done it at some point or another: wishing that one day we might have twins. I know I did when I was a little girl. I carried around my two “waterbabies” until they were worn out. I’d say my mind has changed somewhat since then, but, I’ll admit, I still secretly hope we might, maybe, could possibly, and surprisingly have twins.
Who doesn’t want to have oodles of fun dressing up TWINS?
AND my genetics are favorable… I think. My maternal grandmother had identical twin girls, my aunts. My husband also has twins on his side; his uncles. The little girl in me feels like we are bound to have twins. “They” say it skips a generation. So… maybe?
This got me thinking about what the research actually says about genetics and twins?
*Here’s what I found…
You are more likely to have multiples if:
- Your mom’s family has twins. Did your grandmother or great grandmother have twins? If so, you may be more likely to have multiples.
- You are over 35 years old. Studies show that mothers who conceive over 35 are more likely to have twins because their bodies produce more FSH (follicle stimulating hormone) which may cause more than one egg to release.
- You’ve already had children. Studies show that the more children you have, the more likely you are to have multiples.
- You are taller than 5’2” or have a BMI over 30. Women with these characteristics have higher levels of IGF (insulin-like growth factor) which boosts ovulation, and increases sensitivity to FSH. Additionally, the more protein and fat-rich foods you eat, the better your body is able to cope with carrying twins.
- You have used fertility treatments. Couples who have used IVF (in vitro fertilization) are 25% more likely to have multiples. This can be caused by the multiple implantation of embryos into the uterus, in hopes that at least one will “keep.” Other forms of fertility treatments can cause your body to produce more than one egg, resulting in multiples.
So what are the statistics? What’s the likely hood that you or I could have twins? Well, about 4%. Obviously, if you have one or more of the factors above, you are more likely to have multiples, but statistically speaking 4 out of every 100 births are twins, more than we thought!
So there you have it! If you are hoping for twins (or praying that you won’t), now you know.
