The lining of the uterus that is too thick or too thin has a negative effect on a woman's conception process, causing infertility. So how thick is the uterine lining to get pregnant?
1. What is the uterine lining?
The lining of the uterus, also known as the endometrium, is a layer of tissue that covers the entire inner surface of the uterus. This mucosal layer plays an important role in the ability to conceive and protect the pregnancy process in a woman. Under the influence of the female sex hormone estrogen, the lining of the uterus will become thicker depending on the specific time of the month. Thickening of the uterine lining is a sign of preparation for implantation of a fertilized egg during each menstrual cycle.On the other hand, if the egg is not fertilized, this lining will be peeled off and pushed out of the body. This is the main cause of menstruation in women. In case if conception takes place, female hormones continue to work to make this lining thicker and ready for the implantation process of the fetus.
The lining of the uterus is composed of 2 parts:
Basal layer (basal endometrial layer): Including columnar epithelial cells and stromal tissue, not affected by the menstrual cycle. Superficial layer (endothelial layer): Strongly influenced by changes in the menstrual cycle.

2. The thickness of the uterine lining and its effect on fertility
2.1. The lining of the uterus is too thin
For women whose uterine lining is thinner than 8 mm, it will certainly face many difficulties in the process of conception, namely the implantation process of the fetus.
Even if the fetus has implanted, the ability to keep the fetus in the uterus during pregnancy is still very difficult. The reason is because the lining of the uterus is too thin, not able to hold the fetus. As a result, the fetus is easily aborted, which can lead to miscarriage or stillbirth.
2.2. The lining of the uterus is too thick
Women whose uterine lining is thicker than 20mm is considered too thick. This is also the case that is detrimental to the conception process.
The reason is because the amount of estrogen produced in a woman's body is excessive, stimulating the lining of the uterus to thicken, hindering the implantation of the fetus.
Therefore, if this amount of estrogen is pushed up too high, women will have to face menorrhagia, secondary amenorrhea, polycystic ovaries, ovulatory disorders... All these phenomena Both can interfere with conception.

3. How thick is the uterine lining to get pregnant?
To know how thick the uterine lining is to get pregnant, please compare with the information about the normal thickness of the uterine lining in a woman:
The period when the period has just passed: The endometrium is 3 to 4 mm thick. Mid-menstrual cycle (days close to ovulation): The lining of the uterus is 8-12 mm thick. Menstrual period: The uterine lining is up to 12-16 mm thick. At this stage, if conception does not occur, the lining of the uterus will slough off, forming menstruation.
4. Treatment of abnormal uterine lining to improve fertility
4.1. In case of thin uterine lining
Thin uterine lining can be caused by: estrogen deficiency, endometrial layer damaged due to previous abortions, body ischemia or glandular tissue condition of the uterine lining The uterus grows inside the muscle of the uterine wall... During the examination, depending on the cause, the doctor will choose the appropriate treatment regimen.
4.2. Thick uterine lining
Proliferation of the uterine lining, which causes this tissue to thicken, is common in obese women, women with polycystic ovary disease or who are continuously taking estrogen-containing drugs without progesterone.
For cases of thick uterine lining, doctors often treat with hormones to re-establish the balance of estrogen and progesterone in the body, thereby increasing a woman's ability to conceive.
If you notice any abnormal problems in your ability to become pregnant and your menstrual cycle, you need to go to a hospital with an obstetrician-gynecologist for examination and appropriate treatment.
For women who are planning to become pregnant, performing pre-pregnancy screening is the first thing to do to best prepare a woman for her pregnancy journey. Prenatal check-ups help women detect abnormal problems early in the future in mother and baby, so that appropriate and timely treatment can be provided.
