Does Vitamin D Affect Fertility?

Vitamin D has a lot of important jobs in the body, from promoting bone strength to supporting the immune system. And ongoing research suggests vitamin D may also play a big role in fertility and pregnancy outcomes. 

Dr. Samantha Butts, reproductive endocrinology and infertility specialist at the University of Pennsylvania, sat down with the Women's Healthcast to talk about why Vitamin D is important to fertility, how she incorporates this information when working with her patients, and where the research needs to go next to show how Vitamin D and reproductive health interact.
