Can intercourse or orgasm cause miscarriage or contractions?
In cases of normal, low-risk pregnancies, the answer is no. The contractions that you may feel during and just after orgasm are entirely different from the contractions associated with labor. However, you should check with your health care provider to make sure that your pregnancy falls into the low-risk category. Some doctors recommend that all women stop having sex during the final weeks of pregnancy, just as a safety precaution, because semen contains a chemical that may actually stimulate contractions. Check with your health care provider to see what he or she thinks is best.
