Orgasmic Coitus and Placental Abruption: A Rare Case Report

Understanding Placental Abruption Placental abruption, the premature separation of the placenta from the uterine wall, is a serious obstetric complication affecting 0.4% to 1.0% of pregnancies. It can result in fetal distress, preterm birth, or stillbirth. While common risk factors include hypertension, advanced maternal age, and socioeconomic conditions, sexual activity has not been widely studied as a direct trigger.

Case Summary A 38-year-old woman with a history of multiple pregnancies (8-para, 12-gravida) experienced placental abruption following orgasmic coitus at 29 weeks gestation. Despite an otherwise uneventful pregnancy aside from gestational hypertension managed with nifedipine, the patient developed severe vaginal bleeding shortly after intercourse.

On hospital admission, diagnostic tests confirmed placental abruption and fetal demise. Emergency cesarean delivery was performed, resulting in the delivery of a stillborn infant. Placental histopathology revealed retroplacental hematoma and intervillous hemorrhages, confirming the presence of placental disease. The patient recovered following intensive care treatment.

Clinical Implications and Recommendations

  • Pregnant women with high-risk factors such as hypertension, advanced maternal age, and a history of placental complications should receive tailored counseling on sexual activity.
  • Obstetricians may recommend abstaining from sexual intercourse in cases where uteroplacental perfusion is already compromised.
  • More research is needed to determine the precise mechanisms linking sexual activity and placental abruption.
