365 Days of Twinipedia - Day 16

Day Sixteen of Twinipedia: 

Fact #16

The rate of identical twinning is much higher in mothers that are older.  

The older you are, the higher your chances of having fraternal twins or higher-order multiples. A 2006 study found that women over 35 produce more follicle stimulating hormone (FSH) than younger women. Ironically, increasing levels of this hormone are a sign of failing ovaries and declining fertility. But FSH is also the hormone that causes an egg to ripen in preparation for ovulation each month, and women with extra FSH may release more than one egg in a single cycle. So while older women are statistically less likely to get pregnant, if they do get pregnant, they're more likely to have twins.
