Q+A: Can Sex Bring On Labor?

A. "There isn't really any hard evidence that sex in the later stages of pregnancy can start labor," says Doreen Wiggins, MD, clinical assistant professor of obstetrics and gynecology at Brown University, in Providence, Rhode Island. Still, she says, at least in theory, there are plenty of reasons why it might work.

First, semen contains compounds called prostaglandins that cause contractions. "When we induce someone, we often use a prostaglandin cream or gel to help soften the cervix," Dr. Wiggins explains.

Second, nipple stimulation and orgasm can also trigger uterine contractions. Whether it's enough to actually start labor is still uncertain. But provided your doctor clears you for sex, it certainly can't hurt, so feel free to go for it!
