Introduction
Under normal circumstances, an endometrial thickness of 8–12 mm is suitable for pregnancy. The endometrium is the tissue lining the uterus in mammals and consists of a functional layer and a basal layer. The functional layer undergoes cyclic changes such as shedding and proliferation under the influence of ovarian hormones, while the basal layer remains unchanged throughout the cycle. A normal endometrial thickness is generally considered to be 8–12 mm.
Under normal circumstances, an endometrial thickness of 8–12 mm is considered suitable for pregnancy. The details are as follows:
The endometrium is the tissue lining the inner wall of the uterus in mammals and consists of a functional layer and a basal layer. The functional layer undergoes cyclical changes—such as shedding and proliferation—under the influence of ovarian hormones, while the basal layer remains stable without cyclical alterations. A typical endometrial thickness ranges from 8 to 12 mm. Endometria that are either too thick or too thin are not conducive to embryo implantation and may increase the risk of miscarriage. Changes in endometrial thickness can also be an indicator of uterine abnormalities in women, such as menstrual irregularities and endometritis. Therefore, variations in endometrial thickness significantly affect fertility. For example, endometritis may cause uterine congestion accompanied by exudates, impairing embryo implantation. Infections caused by bacteria, fungi, or other pathogens may lead to embryo death or reduced sperm motility.
Individuals who are trying to conceive should maintain healthy lifestyle habits and minimize external disturbances. Both partners should maintain a positive mental state. Endometrial thickening is usually caused by abnormal estrogen levels. Patients are advised to seek timely medical evaluation and receive appropriate treatment under the guidance of a healthcare professional.
