What to do if the endometrium does not expand

After a woman becomes pregnant, the fertilized egg will develop into a fetus in her uterus. During the development of the fertilized egg, the endometrium of the woman plays an important role. Some women may have an endometrium that is too thin. At this time, they need to think of some ways to adjust it. Because the endometrium is too thin, pregnancy termination or even infertility may occur. So what should I do if the endometrium does not grow?

Normal endometrium is regulated by ovarian sex hormones, and its thickness, morphology, metabolism, and reproductive endocrine function change cyclically. The endometrium is the basis for embryonic development. Endometrium of a certain thickness is a necessary condition for embryo implantation. If the endometrium is too thin, it can lead to a decrease in pregnancy rate or even infertility.

What is thin endometrium?

The uterus is the "palace" where the fetus lives, and the endometrium is the "hotbed" for nurturing life in the palace. It is the home of the embryo and the place where they take root and sprout. Whether the "soil of the hotbed" is fertile plays a key role.

The thickness of the endometrium that is more suitable for embryo implantation is 8-14mm. If a woman's endometrium is thin, it means that the "soil" for implantation is barren, and it is difficult for the embryo to survive when it implants, so the woman naturally cannot become pregnant.

It is currently recognized that the endometrium is considered thin when the thickness of the endometrium is ≤7mm in the late follicular stage.

How does thin endometrium form?

1. Systemic factors

Abnormal function of the female endocrine system, age factors, insufficient secretion of growth hormone or ovulation disorders can affect the normal growth of the endometrium.

2. Local factors

There is a history of intrauterine operations, including multiple curettage and hydrotubation, which may cause endometrial adhesion and damage; severe intrauterine infection; endometrial tuberculosis; uterine fibroids, including multiple, giant or submucosal uterine fibroids; congenital uterine malformations, etc.

3. External factors

Long-term (≥5 years) use of combined oral contraceptives can lead to restricted endometrial growth and reduced menstrual volume. Sudden or long-term increases in work pressure and environmental stress can all be potential factors leading to thin endometrium. At the same time, primary hypertension, diabetes, bad living habits such as smoking and drinking, and being underweight are all correlated with thin endometrium.

4. Unknown reasons

Although some patients have normal endocrine system function, normal sex hormone levels, no clear history of endometrial damage, and no other predisposing factors, hysteroscopy may still reveal thin mid-luteal endometrium even when there is no intrauterine adhesion.
