Study: Sex doesn’t hasten childbirth.

(In the short term, that is.)

From an Ohio State University Medical Center press release:

Women who were sexually active in the final three weeks of their pregnancies carried their babies an average of 39.9 weeks, compared to average delivery at 39.3 weeks among women who abstained from sexual activity at term.

“Patients may continue to hear the ‘old wives’ tale’ that intercourse will hasten labor, but according to this data, they should not hear it from the medical community,” concludes Dr. Jonathan Schaffir, an obstetrician at OSU Medical Center and author of the study published in the June issue of the journal Obstetrics & Gynecology.

Well, what do you know.  I can’t count how many times I’ve heard it said that sex at the end of pregnancy encourages labor to start. 

Question:  Does this now spell the end of the recommendation that women at risk for preterm labor avoid intercourse?

    Hi, Erin,
    Maybe you remember me from the TOTB list a few years ago? I’m Eric’s wife. I linked to your blog from his.
    You have lots of interesting things to say, as always.
    I found this study to be of interest, having had some experience with the role of sex in labor. I’ve found having intercourse to have little or no effect on starting labor, but once labor is going, it can have a big effect! With my second birth, things were pretty slow, contractions 7 to 10 minutes apart, until we decided to try to speed them up “naturally”. From one contraction to the next, they went from 7 minutes to 3 minutes! I’m sure this was not a coincidence. Semen contains prostaglandins, which doctors sometimes use in a synthetic gel form to stimulate labor “unnaturally”.
    We also used this method in our first birth, but much earlier on in labor, and it didn’t have as dramatic effect, but did have a more subtle effect.
    Now, it’s not so much fun to have intercourse once labor has started, but it’s better than the alternative sometimes, if that’s a long, slow, labor that’s exhausting the mother.
    Anyway, that’s my
    experience.
    By the way, congratulations on your pregnancy!
