Introduction

NT refers to the thickness of the translucent layer beneath the skin at the back of the fetal neck, which is commonly measured during an ultrasound screening in early pregnancy to assess the risk of chromosomal abnormalities such as Down syndrome. Generally, after a normal NT scan at 12 weeks of pregnancy, women can resume sexual activity, but should avoid overly vigorous intercourse.

Sexual intercourse is generally permissible at 12 weeks of pregnancy if the NT (nuchal translucency) measurement is normal, but should be avoided if the pregnant woman has poor physical health. The detailed analysis is as follows:

I. Sexual intercourse is allowed

NT refers to the thickness of the translucent layer beneath the skin at the back of the fetal neck, which is commonly assessed during an ultrasound screening for intrauterine pregnancy to evaluate the risk of chromosomal abnormalities such as Down syndrome. Generally, women may resume sexual activity after a normal NT scan at 12 weeks of pregnancy, though overly vigorous sexual activity should be avoided.

II. Sexual intercourse should be avoided

At 12 weeks of gestation, the fetus inside the uterus has not yet fully developed and may be vulnerable to external pressure or stimulation, potentially causing adverse effects. If the pregnant woman has a weak constitution or experiences significant pregnancy-related symptoms, sexual intercourse is not recommended to avoid harm to either the fetus or the mother.

Before and after sexual intercourse, it is essential to maintain cleanliness of the vagina and external genitalia to prevent bacterial infection. During pregnancy, underwear should be changed frequently to ensure good external hygiene.
