Sponsor's own description

This study, conducted at the Naval Medical Center in San Diego, CA, will determine if having vaginal intercourse in the last weeks of pregnancy decreases the risk of having a prolonged pregnancy. Pregnancies that continue beyond the due date may increase health risks for the mother and the baby. Although some believe that vaginal intercourse can help start labor in the last weeks of pregnancy, there is not proof that it works. Some studies showed that sexual intercourse helped and some that pregnancy lasted even longer for couples having sex. In addition to exploring the effect of sexual intercourse on time to delivery, this study will collect information that can be used in the future to predict when labor will naturally start and the risk for overdue pregnancies. Women 18 years of age and older in their first pregnancy who are carrying a single fetus with gestational age before 38 plus 6 weeks may be eligible for this study. Candidates must be living with their partner in a stable relationship. Participants are asked to have sexual intercourse about three times per week. They complete a diary in which they record the times they have intercourse and how they are feeling daily. The diaries are submitted by mail each week or at the doctor's or midwife's visit until delivery. The women have a pelvic exam and ultrasound and complete questionnaires about problems during pregnancy, overall well-being, attitude toward induction of labor, physical activity, body image during pregnancy, stress and social support, habits at home, and environmental conditions, such as weather.
