Can An Orgasm In The First Trimester Cause A Miscarriage? Science Answers


The first trimester is a really nerve-wracking time in your life. You're probably nervous about a lot of things, and on top of that, your hormones are all over the place. If you're feeling especially amorous (amidst all the morning sickness), sex can be a great escape from worry. But, can an orgasm in the first trimester cause a miscarriage?

I understand the concern. I mean, orgasms were once called "la petite mort" or "the little death." It's an encompassing sensation that almost feels too big for pregnancy — like it could be unsafe. Such a systemic reaction seems like it could cause as much harm as it does fun, doesn't it?

Thankfully, most women can have sex and have as many orgasms as they like, regardless of where they are in pregnancy. From the day that embryo implants in your uterus until the day you go into labor, it's a safe activity so long as your OB-GYN or midwife has given the go ahead, according to The Mayo Clinic.

That doesn't mean you'll want to have sex, or have to do it — it just means that you can. And there's good science as to why orgasms may benefit you during pregnancy, not just emotionally, but physically as well, according to Parents Magazine.


However, you may notice after you have sex, and that resulting orgasm, that you're spotting lightly and cramping. That's completely normal, according to the Mayo Clinic. The prostaglandins released by orgasm, and the prostaglandins that exist in semen (if you're having sex with a male), can both trigger uterine contractions. Provided they're not intense, and that they don't last more than a few hours after you've had an orgasm, it's nothing to worry about. The spotting is due to increased blood supply to the region, especially near the surface. This means that any tiny tear that might happen during sex will likely show up as a bit of spotting on your underwear, or present when you wipe after going to the bathroom. As long as it's not menstrual heavy, it's nothing to worry about.

If you are worried, you should call your provider. Talk it over with them to allay your concerns and to discuss with how your sex life may or may not proceed through the pregnancy. It's all about safety and comfort, and the ability to have both.
