Research indicates that sexual intercourse is safe in the absence of ruptured membranes, bleeding, or placenta previa, but pregnant women engage in sex less often as their pregnancy progresses. No studies have suggested that any particular position is unsafe, although a 1993 study demonstrated a 2-fold increased incidence of preterm membrane rupture with the male-superior position compared to other positions. ACOG states that sexual activity during pregnancy is safe for most women right up until labor, unless there is a specific contraindication.
ACOG specifically cautions that a women should limit or avoid sex if she has had preterm labor or birth, more than one miscarriage, placenta previa, infection, bleeding, and/or breaking of the amniotic sac or leaking amniotic fluid. ACOG discusses that, as part of natural sexuality, couples may need to try different positions as the woman's stomach grows. Vaginal penetration by the male is not as deep with the male facing the woman's back, and this may be more comfortable for the pregnant woman.
