Patient's question:
Is sexual intercourse suitable during pregnancy? Does engaging in sexual intercourse after the seventh month have an impact on the fetus?Doctor's answer:
Generally speaking, sexual activity is not advisable during pregnancy, especially in the first three months and the last three months. Although some opinions suggest that sexual intercourse during pregnancy is not a major issue, in fact, many cases of miscarriage, preterm birth, premature rupture of membranes, and postpartum infections are caused by sexual activity. The main hazards of sexual activity during pregnancy include:1. Increased risk of uterine contractions leading to miscarriage or preterm birth. There are two main reasons:
- Mechanical stimulation during intercourse causes congestion in the external genitalia and pelvic organs. During orgasm, the perineum, vagina, and pelvic floor muscles contract rhythmically, and the uterus may also contract, increasing the risk of miscarriage or preterm birth.
- Sperm contains prostaglandins, which can stimulate uterine contractions, leading to placental separation, miscarriage, premature rupture of membranes, or preterm birth due to cervical dilation.
2. Potential for antenatal, intrapartum, and postpartum infections. This is because both male and female external genitalia are often contaminated with bacteria. Sexual activity can easily lead to premature rupture of membranes, allowing alkaline amniotic fluid to leak, which promotes bacterial growth and infection in the uterine cavity. Postpartum cervical lacerations also provide an opportunity for bacteria to enter, making infection more likely.
If sexual activity occurs occasionally during the second trimester of pregnancy, the following precautions should be taken:
(1) Maintain cleanliness of the genital organs—both partners should clean their external genitalia before intercourse.
(2) Exercise restraint, especially avoiding rough movements from the male partner. It is best to avoid the male-on-top sexual position.
