Abstract

This study investigated whether sexual intercourse during pregnancy is associated with spontaneous preterm birth (SPTB). We included 77 women with SPTB and 145 women with a term birth. A total of 195 (87.8%) women had sexual intercourse during pregnancy, which was comparable between the groups. Primiparas with SPTB tended to report more often having sexual intercourse 3 – 4 times a week compared to primiparas with a term birth (8.8% vs. 0%, p =.082). We advise not to completely discourage sexual intercourse among pregnant women. Yet, high sexual intercourse frequency could be associated with SPTB.
