Everyone knows that the 35 year old queen, Beyonc̩, finally welcomed her twins into the world. Earlier this summer, George Clooney and Amal also had twins, adding to the growing list of Hollywood twins. Recent studies have shown that women aged 35 and older have better chances of giving birth to twins. Queen Bey is 35 and Amal is 39, coincidence? I think not.
Now more than ever, women are having their first child in their thirties, including millennial women. Often times we jump to conclusions and assume that women in their mid to late thirties pregnant with twins have undergone fertility treatment. Of course IVF and other advances in fertility treatments contribute to the growth in twin population, however it's not just those treatments that lead to twins. The biggest factor is actually hormones. Women aged 35 through 41 have a noticeable shift in hormones that makes them more likely to have twins because they are able to prepare more than one egg during their menstrual cycle. This is because of higher levels of a pregnancy-related hormone called follicle-stimulating hormone.
So, look out millennials and future mommies to be. Waiting until you're in your thirties may just give you two or three babies instead of one.
