Pregnancy and obesity: Know the risks

Could having a high BMI affect my ability to get pregnant?

Having a high BMI can lessen the ability to become pregnant, also called fertility. A high BMI can affect the process called ovulation in which an egg is released from an ovary. The higher the BMI, the longer it may take to become pregnant. And that's true even in people who regularly ovulate. A higher BMI also may be linked to a greater risk of a fertility treatment called in vitro fertilization not working.
