Does Sex Induce labor?

"Does sex induce labor?" This is a question often asked of practitioners by their pregnant patients. The answer may, or may not, be something you wish to hear at nine months pregnant.  The role of sexual intercourse in the initiation of labour is uncertain since a limited amount of data is available.  The truth is that it may help.


 It's not necessarily associated with starting labor but may help to ripen the cervix. Semen is the greatest (umm, highest;-) source of prostaglandins. Prostaglandins cause the cervix to "ripen", or soften and prepare to open. Sex can help the cervix to dilate and efface by depositing these prostaglandins on the cervix.


Furthermore nipple stimulation may also have a role in that it is known to release oxytocin, the hormone that causes contractions.  In addition, orgasms produce oxytocin.   So, between these factors, there is a pretty good case for the stimulation of labor.


However, for women who have complications such as sciatica, pubic symphysis dysfunction or other health issues which make intercourse too painful to attempt or ill-advised for their circumstances, there may be alternative options that provide some of the same benefits.   This method can also be used by other women who are simply too uncomfortable, exhausted from work, have other children to attend to or simply don't desire sex at 9 months pregnant. 


As an alternative to intercourse, you might consider collecting semen in a condom, a diaphragm or an Instead cup to hold the semen against the cervix. An Instead cup is designed for use during menstruation, but theoretically could be used in this manner.


It's important to note I know of absolutely no studies about any of this, so you're on your own. If anyone's circumstances make this the preferred course, use the contact form to report your success, or lack thereof.
