What is the role of the endometrium during pregnancy?

Endometrium is called the inner mucous membrane of the uterus. It is abundantly supplied with blood vessels. Its thickness depends on the phase of the menstrual cycle.endometrium and pregnancyEndometrial thickness - important for pregnancyindicatorPhoto: GettyThe endometrium has the smallest thickness immediately after the end of menstruation. Later, it begins to grow and reaches a thickness of 17–20 mm by the end of the cycle. If fertilization does not occur, its particles are rejected and leave with blood during the next menstruation. But if ovulation occurs during conception, menstruation does not occur and the endometrium continues to develop. This is necessary for successful implantation and fixation of the ovum. Endometrium in early pregnancy has a thickness of about 20 mm. An experienced specialist is able to see this during the ultrasound and suggest pregnancy, even if the ovum is not yet visible. The endometrium is actively supplied with blood and subsequently becomes part of the placenta, through which nutrients are supplied to the baby.

Endometrial thickness: norm and pathology

Often, various endometrial pathologies becomecause unsuccessful attempts to get pregnant. In order for the fertilized egg to penetrate the wall of the uterus, the thickness of its mucous membrane must be at least 7 mm. If the endometrium is not growing well, it is called hypoplasia. The embryo simply has nowhere to gain a foothold, and the pregnancy fails. The reasons for this may be inflammatory processes, genital infections, abortions in the past. The opposite situation also occurs. Excessive growth of the mucous membrane is called endometrial hyperplasia, pregnancy with it is also very problematic. The reasons for hyperplasia are hormonal imbalance, endometriosis, uterine myoma. Therefore, it is so important to plan a pregnancy and pre-check the doctor. In order to treat hypoplasia, hormonal preparations and physiotherapy procedures are prescribed. Hyperplasia is eliminated with the help of hormonal correction, and surgical intervention is often required. Endometrial thickness and pregnancy are closely related, this is one of the first indicators that need to be checked when planning a pregnancy.
