Can Sex During Pregnancy Induce Labor?
Prostaglandins - Reproduction, Inflammation & Other Conditions | Everyday Health
Human semen is the biological source that is presumed to contain the highest prostaglandin concentration. The role of sexual intercourse in the initiation of labour is uncertain. The action of sexual intercourse in stimulating labour is unclear, it may in part be due to the physical stimulation of the lower uterine segment, or endogenous release of oxytocin as a result of orgasm or from the direct action of prostaglandins in semen. Furthermore nipple stimulation may be part of the process of initiation. This is one of a series of reviews of methods of cervical ripening and labour induction using standardised methodology.

What Are Prostaglandins?
NEW YORK - Despite a widespread belief that sex during the later stages of pregnancy can jumpstart labor, a new study from Malaysia found no differences in the timing of delivery between women who had sex near term and those who abstained. Tan Peng Chiong, an obstetrics and gynecology professor at the University of Malaya, and one of the authors of the study. Tan said that many women believe intercourse can induce labor, and scientists have proposed plausible biological explanations for why it might help.
Most women experience some menstrual pain, For up to 15 percent, it is severe enough to interfere with work and other activities for one or more days every month. In the s, it became evident that chemicals called prostaglandins are a central part of the problem. These chemicals are made from the traces of fat stored in cell membranes, and they promote inflammation. They are also involved in muscle contractions, blood vessel constriction, blood clotting, and pain. Shortly before a period begins, the endometrial cells that form the lining of the uterus make large amounts of prostaglandins.
