This is a preliminary, prospective study of uterine contractility in response to sexual intercourse. The study population consisted of 30 pregnant subjects. Group I included 15 women treated for an episode of preterm labor with intravenous and oral tocolysis in this pregnancy, and group II was a matched control group of low-risk volunteers. The availability of home uterine tocodynamometric systems permitted monitoring of uterine contractility for three 60-minute time periods related to coitus. A significant increase in uterine contractility in the immediate postcoital period was observed for the high-risk women, but not for the controls. This increased uterine activity subsided spontaneously within 2-3 hours, returning to baseline. These initial preliminary observations of uterine response to coitus in a home environment are interesting; however, further research is suggested to establish their clinical implications.
