The endometrium is the soil of breeding fetuses. Many pregnant mothers are very concerned about the endometrium problems. They are too thick and afraid of being too thin to affect pregnancy.In fact, the thickness of the endometrium is not a fixed value, and it is changing.
The endometrium is one of the most differentiated tissues in the human body. The main role is to form menstruation when women are not pregnant. The rapid proliferation during women’s pregnancy provides nutrition for embryonic growth and development.The endometrium is divided into two layers, one is the base layer and the other is the functional layer.The base layer is not affected by the changes in ovarian hormones during the menstrual cycle, and the menstrual period remains unchanged; the functional layer is affected by the impact of ovarian hormones, and the menstrual period will fall off.Therefore, the thickness of the endometrium changes periodic changes with the menstrual cycle.
How much is the thickness of the endometrium suitable for pregnancy?
The thickness of the normal endometrium is constantly changing as the menstrual cycle, and it is not constant.In fact, the thickness of the endometrium is relatively speaking. There is no exact standard to say to which extent can the endometrium thick or thinner cause infertility.The endometrium has gone through three different stages of menstrual period, hyperplasia, and secretion periods that have experienced the whole process from falling to growth, becoming fertile, to falling off.Generally, the thickness of the normal uterine endometrium ranges from 5-10mm. In different periods of endometrium, the thickness is also different.
Menstrual period
The first-4 days of the menstrual cycle is the endometrium of the menstrual period. At this time, after the luteal degeneration of the ovaries, the amount of estrogen and progesterone decreases, the endometrial ischemia, the tissue necrosis falls into the uterine cavity, and is discharged from the vagina, which is menstrual blood.At this time, the endometrium is in a state of falling off, which is very thin, and the thickness is about 1-4mm.
Hyperplasia
After the menstrual tide, follicles will grow in the ovaries. Under the act of estrogen secreted by follicles, the endometrium has hyperplasia. At about 5 to 9 days in the menstrual cycle, the endometrium is very thin.In the sky, the endometrium becomes thicker and ribs, and the gland and the quality are significantly hyperplasia.
Secretion
On the 15th to 19th day of menstruation, 1 to 5 days after ovulation, the endometrium continues to increase, and the glandular body further increases and bent.About 20 to 24 days of the menstrual cycle, 6 to 10 days after ovulation, highly secretion activity occurred in the endometrium, and the bending and expansion of the glands reached its peak.By the advanced secretion, the thickness of the endometrium is about 5-6mm.
Severe endocrine disorders, multiple abortion, and uterine developmental deformities, etc., can easily lead to thinning endometrium. If the endometrium of women is thin, the embryo is difficult to go to bed smoothly, and even if it is successful in bed, it is easy to abortion in the early stages of pregnancy.If you find that the endometrium is thin, you must go to the hospital for examination and treat the cause in time, and follow the doctor’s guidance to avoid affecting the childbirth.
