Does Your Fetus Masturbate In Utero? Here’s What Research Suggests

Fetus Masturbate In Utero

It’s not every day you hear the words “fetus” and “masturbate” in the same sentence. Most people probably wouldn’t put the two together for obvious reasons, but for some, especially researchers, it’s genuinely a subject of fascination. And why not? Many humans masturbate so it only makes sense to wonder ” does your fetus masturbate in utero?” Although the science on the subject is a bit lacking, there is some research to point to an answer.

“There is no doubt that we can see the fetus touch their genital as early as 15 to 16 weeks, Dr. Sherry A. Ross, author of She-ology: The Definitive Guide to Women’s Intimate Health. Period  tells Romper. “There have also been isolated observations showing this phenomenon, but no definitive studies have been shown this as a purposeful movement to create pleasure.” One of the observations she’s referring to is a report that gets discussed in the news frequently. It was an observation made by two OB-GYNs in 1997 regarding fetal masturbation. Yes, that was a long time ago, but it bears relevance because it’s been so widely talked about.

According to U.S. News & World Report, the two OB-GYNs had “recently observed a female fetus at 32 weeks gestation touching the vulva with the fingers of the right hand” before the female fetus experienced prolonged spasms, and “finally…relaxed and rested.” Unfortunately, the full text of the article is no longer available. Given the ambiguous circumstances surrounding any actual data surrounding fetal masturbation, it’s hard to make conclusions.

But as Ross says, babies make many movements in utero. Through 3-D imaging, I was able to see my baby clasp her hands in prayer form like a little yogi at 3 months gestation. So if my baby was able to make that movement, kick, and flip in the womb, is it possible that fetuses can make intentional masturbation movements as well? And if yes, do they get pleasure from it? This is where things get even more unclear, as the medical community doesn’t exactly agree on whether fetuses, especially very young gestational age fetuses, can feel sensations. Two Italian researchers published in The Journal of Maternal-Fetal and Neonatal Medicine said it seemed possible for fetuses to feel pain in the third trimester, but it was hard to conclude if they did before that time because the data was weak. That said, however, they studied pain rather than pleasure.

Another voice worth bringing into the conversation comes from Dr. F. Session Cole, a professor of pediatrics at Washington University School of Medicine and a neonatologist who cares for newborns born prematurely at 22 to 24 weeks gestation. In a TIME article, it was reported that:

As said, it’s extremely difficult to make conclusions about fetal masturbation given the data and research available. In the end, it all seems to boil down to pain-pleasure sensations for a fetus in utero, to which one could presume will be studied sometime in the future if it isn’t at this very moment.
