Endometrial thickness changes

As we all know, the womb is an area where new life is created and born. The thickness of the uterine wall can be neither too thick nor too thin. The thickness of the endometrium is not a numerical value, because the thickness of the uterine wall changes with the changes in the menstrual cycle.

During the menstrual period, due to the decline of progesterone in the ovaries, the secretion of estrogen and estrogen in women will decrease in a very short period of time. The spiral aorta in the functional layer of the uterine wall will continuously contract, causing ischemia of the uterine wall. The necrotizing tissue will fall into the uterus and be discharged from the vagina, thus causing menstruation.

During menstruation, the uterine wall is in a state of falling off, so it is very thin, about 1-4mm, and looks like a thin rope. At this time, the boundary between the uterine wall and the uterine myometrium is not very clear, but it is indeed undergoing a transformation, and after the replacement of the old with the new, it will present a brand new appearance.

As women's menstruation fades, there are multiple eggs growing in their ovaries. Under the action of warm and secreted estrogen, the uterine wall will change again and gradually thicken. The uterine wall can be completely repaired before the next menstrual period ends. This stage is called the proliferative phase.

The thickness of the endometrium will vary at different stages.

Because the thickness of the female uterine wall shows regular changes, for women of childbearing age with a menstrual cycle of 28 to 30 days, the endometrial thickness in the follicular phase should be around 4-5mm, and for women in the ovulation period, the thickness of the uterine wall should be around 8-10mm, but for those women in the follicular phase, the thickness of the uterine wall should be around 10-12mm.

The thickness of the endometrium can be said to be closely related to the female reproductive organs and endocrine system. Under normal pregnancy conditions, the uterine wall is an area for the embryo to implant. If the uterine wall is too thin or too thick, it is not conducive to the growth of the test tube embryo. However, the thickness of the endometrium is relative to a certain extent. There is no accurate standard in clinical medicine that says that if the endometrium is too thin or too thick, pregnancy is impossible.

The uterine wall will gradually become thicker and looser under the stimulation of the female hormones and estrogen secreted by progesterone, especially under the stimulation of estrogen, just like a soft sponge bed with a lot of nutrients. Once the sperm and egg combine, the embryo will implant on the uterine wall and then begin to create life. If a woman does not get pregnant this month, the uterine wall will fall off again 28 days after the menstrual cycle, and the woman will have her period.
