Sex During Pregnancy

Throughout the course of your pregnancy, you will experience a wide range of emotions and physical changes. One change you or your partner may encounter is an increased or decreased sex drive. Hormones, body image, relationship issues and prenatal health can affect your sex drive and your ability to engage in sexual activity.

Sexual Desire
A woman’s desire for sex during pregnancy can fluctuate month-to-month or trimester-to-trimester. During the first trimester, fatigue, vomiting and nausea may put a damper on sexual activity. By the second trimester, many women regain energy and feel more aroused due to physical changes such as full breasts, increased vaginal lubrication and increased blood flow to the pelvic region. Once the third trimester arrives, fatigue and body aches and pains may decrease your sexual desire.

Your partner may also experience an increased or decreased sex drive. In one respect, your partner may be aroused by your full breasts and round belly, trying new sex positions (to account for your growing abdomen) and a newfound freedom from concerns about contraception. On the other hand, your partner may feel anxious due to a fear of causing you discomfort, harming the fetus, or nervousness about becoming a parent.

Communicating With Your Partner
Talk to your partner about your comfort level regarding the amount of sex you would like to have, the different positions you would like to try, and where you would like to be touched. Ask your partner about his preferences as well.

Participating in sexual activity while pregnant can be enjoyable, and as long as you are experiencing a healthy or “normal” pregnancy, sex during pregnancy does not harm your baby. The penis does not come into contact with the fetus during sex due to the mucus plug in your cervix and the muscles of the uterus. In addition, it is safe for a pregnant woman to reach orgasm.

When Sex During Pregnancy is Not Safe
Sex may not be a safe activity if your pregnancy is considered high-risk or if other significant complications exist. Your doctor may advise against sex during pregnancy if you are diagnosed as having any of the following conditions:

  • Unexplained vaginal bleeding
  • The presence of symptoms (cramping or contractions) or risk factors (multiple pregnancy including twins, triplets or more) that may indicate or predispose a woman to preterm labor
  • Leakage of amniotic fluid (the fluid that surrounds the baby)
  • Placenta previa, occurs when the placenta is situated in an area that covers the cervix (opening of the uterus)
  • Incompetent cervix, a condition in which the cervix is weakened and opens (dilates) prematurely, increasing the risk for miscarriage or premature delivery

If you are unsure whether sex during pregnancy is safe for you, contact your obstetrician. In addition, if you notice any unusual symptoms after intercourse, contact your health care provider immediately. Mild cramping may follow sexual intercourse and orgasm. This cramping is due to the prostaglandins (hormones that help induce labor) in semen and contraction of pelvic muscles during orgasm. The cramping should be mild and short-lived. If cramping persists or intensifies to regular contractions, contact your obstetrician.

It is important to abstain from sexual activity with a partner who has or may have a sexually transmitted disease (STD) such as genital warts (HPV), chlamydia, herpes or human immunodeficiency virus (HIV). Some STDs can be transmitted to the fetus or to the newborn at the time of birth. Some people with an STD may show no signs or symptoms. Avoid having sexual intercourse with a partner whose sexual history is unknown to you.

Sexual Activity During the Latter Stages of Pregnancy
During the latter half of your pregnancy, sexual intercourse in the missionary position (woman flat on her back) should be avoided. When flat on your back, the enlarged pregnant uterus may compress the blood vessels along your spine that are returning blood to your heart. This can cause a sudden drop in your blood pressure and a feeling of dizziness. To maintain good blood flow to the uterus, lie on your side during the latter half of pregnancy.

Talk to your doctor about sexual activity during the final weeks of your pregnancy. If you experience vaginal bleeding or have a history of preterm labor, your doctor may advise you to abstain from sexual intercourse. The hormone prostaglandin is present in semen, but not in the amount required to induce labor. In general, sexual activity will not trigger labor unless your body is ready.

How Soon Can I Have Sex After the Baby is Born?
Medical opinions vary as to when you should resume sexual activity after delivery. It is recommended that you wait until after your postpartum checkup before you resume intercourse.

Every woman's pregnancy is different. Talk to your doctor, nurse or midwife regarding any concerns you may have about your sexual activity and prenatal health.
