Sex During Pregnancy: Myths vs. Truths

Sex in pregnancy: myths and realities without taboos

Pregnancy is a stage of profound physical, emotional and social changes, and one of the topics that usually generates the most doubts – and silences – is sex. Is it safe? Can it harm the baby? Does it affect childbirth? In this article we debunk myths, speak openly and tell you what science says about sex during pregnancy.

Is it safe to have sex during pregnancy?

In a normal, uncomplicated pregnancy, having sex is completely safe. There is no evidence that intercourse or orgasm harms the fetus or causes preterm birth in low-risk pregnancies.

According to the American College of Obstetricians and Gynecologists (ACOG), sex does not pose a danger in uncomplicated pregnancies and can continue throughout trimesters, as long as there are no medical contraindications.

Common myths about sex in pregnancy

There are many myths that generate guilt or fear. Let's debunk the most common ones:

Having sex cannot cause a miscarriage. Most abortions occur because of genetic abnormalities and not because of sexual activity.

WHO

"The penis can hit the baby."

False. The baby is protected by the uterus, the amniotic sac, and the mucus plug of the cervix. There is no way to "touch" it.

"Sex can induce labor."

In a full-term pregnancy, orgasm or prostaglandins in semen could, in theory, stimulate the uterus. But there is no conclusive evidence that they induce labor under normal conditions.

"You shouldn't have sex in the third trimester."

It is not true either, unless the professional indicates otherwise. Many couples adapt positions for comfort.
Pregnant couple showing physical affection

Intimacy can be strengthened during pregnancy, always with consent and comfort.

When should sex be avoided in pregnancy?

Although in most cases it is safe, there are some medical situations where it is recommended to avoid vaginal sex:

  • Threat of preterm labor.
  • Placenta previa (the placenta covers the cervix).
  • Premature rupture of membranes.
  • Vaginal bleeding with no clear cause.
  • Active genital infections.
  • Cervical incompetence or short cervix.

In these cases, it is essential to follow the instructions of the health professional. Every pregnancy is unique.

Changes in libido during pregnancy

Libido in pregnancy can increase, decrease, or fluctuate, and everything is normal. Some factors that influence:

  • Hormonal changes (estrogen, progesterone).
  • Physical discomfort such as nausea, fatigue, or lower back pain.
  • Body image and self-esteem.
  • Emotional connection with the partner.

Talking openly, experiencing new forms of intimacy (such as massage, caresses, mutual masturbation) and adapting postures can be very positive.

Sex is an important part of emotional well-being during pregnancy, as long as it's consensual and comfortable for both people.

Sex, couple and communication

Pregnancy can be a time of deep emotional connection, but also of insecurities. Talking about wants, fears, and needs strengthens the bond. Not all sexual relations have to involve penetration: affection, play and eroticism also count.

The desire of the non-pregnant couple also changes. Empathy, respect, and open communication are key.

And after childbirth?

After delivery, it is usually recommended to wait between 4 and 6 weeks to resume vaginal intercourse, depending on the type of delivery, presence of tears, episiotomy and bleeding. However, every woman and every body has her rhythm.

Vaginal dryness, pain, tiredness, and emotional changes are common. The use of lubricants, the pelvic floor and emotional validation are important allies. If there are persistent difficulties, it may be helpful to consult a specialist midwife or sexologist.
