Which hormone might contribute to multiple births and why?
Other factors that have greatly raised the multiple birth rate in recent years are reproductive technologies such as: Ovulation-stimulating medicines, such as clomiphene citrate and follicle stimulating hormone (FSH). These help produce many eggs. If fertilized, they can result in multiple babies.
What makes you more likely to have twins?
As you age, your chance of conceiving twins increases. Researchers have found that women over 35 produce more follicle stimulating hormone (FSH) than younger women, which may cause more than one egg to drop at ovulation. You’ve been pregnant before.

But in a rare phenomenon called superfetation, another egg is released, gets fertilized with sperm, and attaches to the wall of the uterus, resulting in two babies.
