Introduction

Loss of libido during pregnancy is generally associated with hormonal fluctuations, physical discomfort, increased psychological stress, concerns about fetal safety, and changes in lifestyle. During pregnancy, levels of estrogen and progesterone fluctuate significantly. In early pregnancy, rising estrogen levels may temporarily affect libido, while the continuously increasing progesterone levels in the second and third trimesters can suppress neural signals related to sexual desire, leading to a marked decrease in sexual drive.

Loss of libido during pregnancy is generally related to hormonal changes, physical discomfort, increased psychological stress, concerns about fetal safety, and changes in lifestyle. The specific factors are analyzed as follows:

1. Hormonal changes: During pregnancy, levels of estrogen and progesterone fluctuate significantly. A rise in estrogen early in pregnancy may temporarily affect libido, while the continuously increasing progesterone levels in the second and third trimesters can suppress neural signals related to sexual desire, leading to a noticeable decrease in sexual drive. This is a natural physiological response as the body adapts to the pregnant state.

2. Physical discomfort: Common symptoms during pregnancy such as nausea, vomiting, backache, fatigue, and frequent urination can be physically draining. These discomforts consume considerable energy, making it difficult for pregnant women to feel sexually interested. Particularly during the first trimester with severe morning sickness or in the late stages when abdominal heaviness increases, physical discomfort further reduces libido.

3. Increased psychological stress: Pregnant women may experience fear of childbirth, anxiety over body image changes, and worries about future parenting responsibilities. These negative emotions can dominate their attention, diverting focus away from sexual intimacy and consequently leading to decreased sexual desire.

4. Concerns about fetal safety: Many pregnant women worry that sexual activity might harm the fetus—such as triggering miscarriage, preterm labor, or infection. These concerns can cause hesitation and lead women to avoid intimate contact voluntarily, resulting in reduced libido.

5. Changes in lifestyle: Poor sleep quality, reduced time spent together with partners, and increased focus on fetal health alter daily routines and affect the emotional intimacy between couples. As a result, both partners may experience diminished interest in sex, manifesting as lowered libido in the pregnant woman.

During pregnancy, couples should communicate openly about their feelings and show mutual understanding and patience. If low libido affects emotional well-being, consulting a healthcare provider for professional advice is recommended. Engaging in activities such as walking or gentle physical affection can help strengthen emotional bonds and prevent relationship conflicts arising from sexual concerns, allowing couples to navigate pregnancy together smoothly.

Why do some people give birth at 37 weeks?

Some women give birth at 37 weeks, often due to reasons such as fetal maturity, maternal hormonal changes, abnormal uterine contractions, a history of preterm delivery, or multiple pregnancies. A 37-week gestation is considered full-term, but maternal and infant health should still be closely monitored. If symptoms such as abdominal pain, vaginal bleeding, or rupture of membranes occur during pregnancy, prompt medical attention is recommended. Some fetuses are already fully developed by 37 weeks.
