How much endometrial thickness is normal?

Female friends often consult: "My lining is too thin to transplant, what should I do?" ”

"Other doctors told me that the lining was too thin, which affected pregnancy."

This question is sometimes really difficult to answer in a simple sentence. Let's discuss this issue with you today.

How is the thickness of the endometrium calculated?

The thickness and thinness of the endometrium are cyclical

When it comes to the thickness or thinness of the lining, it is best to say that it is on the first few days of the menstrual cycle. At the beginning of a woman's menstrual cycle, that is, the menstrual period, the endometrium has just been completely peeled off, that is, when a large amount of menstrual bleeding during the menstrual period is close to the end, the lining should be very thin, which can be described as a line, that is, as thin as a line, and the doctor will record the intima as "linear" in the medical record book.

If the thickness of the endometrium is still more than 7 mm near the end of the menstrual period, it means that the endometrial detachment is not complete, but it is not normal. In general, at the end of a large amount of menstrual blood during menstruation, it is best to be less than or equal to 5 mm.

Then into the follicle development period, the follicle in the ovary starts to develop, with the continuous development of the follicle, will continue to secrete estradiol, estradiol mainly acts on the endometrium, so that the endometrium is also constantly thickened, therefore, the thickening of the endometrium is accompanied by the development of follicles, in general, if the diameter of the dominant follicle reaches or exceeds 15mm, the thickness of the endometrium should be 7-8mm or more, and the thickness of the endometrium in normal women can reach about 9mm at this time.

Therefore, the thickness of the endometrium is closely related to the size of the follicle, and the two cannot be separated.

What is the A/B/C Inner Membrane?

The endometrium is divided into A, B and C under ultrasound.

The "A/B/C" type intima is often referred to as a different morphology of the endometrium, rather than a level evaluation.

The "A/B/C" type lining not only changes with the menstrual cycle, but is also related to the position of the uterus, such as the median uterine endometrial form is mainly "B" or "C" type.

Type A inner membrane:

That is, the three-line inner membrane, the outer layer and the center are strong echo lines, and the outer layer and the middle line of the uterine cavity are low echo areas or dark areas. It is common in the early stages of endometrial hyperplasia (usually days 6 to 10 of menstruation), when the endometrial thickness is 4-9 mm.

Type B inner membrane:

It is a uniform medium intensity echo, and the median line of the strong echo of the uterine cavity is intermittent. It is common in late endometrial hyperplasia (11th day of menstruation - ovulation), when the thickness of the intimal membrane is about 9-12 mm.

C-type inner membrane:

It is a homogeneous strong echo, without the midline echo of the uterine cavity, at which time the "three-line sign" disappears. It is common in the luteal phase (i.e., after ovulation and before the next menstrual period) and is about 10–14 mm thick.

Common problems with inner membranes

What should I do if I have a thick lining and polyps?

Polyps are easy to handle, but a few people relapse. It is not difficult for the attending physician to choose a reasonable plan.

Why do people who have never been pregnant or had uterine surgery also stick?

Inflammation can also cause adhesions. Chronic mild inflammation you don't necessarily feel, just like people who haven't had an abortion or surgery have blocked fallopian tube adhesions.

Why do some people have few follicles, but the intima is still very good?

Follicles and lining are two different things, as long as the intima is not diseased, with a certain amount of estrogen intima can grow, the use of progesterone can also be converted.

I have a bit of a thin lining, but I have never had an abortion before, and I was pregnant for the first time before, is this thin intima congenital? How do I thicken the intima before my next pregnancy?

There are two causes of thin intima: one is that the follicle is not developing properly. The final stage of follicle development, that is, the estrogen level before the peak of ovulation appears, or ovulation before the tenth day of the cycle, in these cases the intima can not be fully developed, manifested as a thin intima, the intima itself has no problems, generally through ovulation induction can be solved. There is also a case where there is organic damage to the inner membrane. There is no response to estrogen of the stimulin, such as curettage, infection, tuberculosis, etc., which need to be resolved by hysteroscopy.

Do uterine fibroids affect implantation?

Depending on the location and size of the fibroids, if the fibroids grow under the mucous membranes inside the uterine cavity, even if they are small, they may affect the implantation of the fertilized egg.

Do pelvic adhesions affect pregnancy?

It is not easy to conceive naturally, but it has little effect on IVF transplantation.

Improve the endometrium in preparation for conception

The womb, as the name suggests, is the "palace" of the future child, that is, the "house" of the future baby. If the embryo is likened to a "seed", then the uterine lining is the "soil", and hormone levels and mood are equivalent to sunshine and rain.

Improving the quality of eggs and sperm is also to have a high-quality "seed", conditioning the uterine environment, especially the endometrium, maintaining a good mood, maybe we and the child just need a tacit understanding or a fate.

After long-term careful research, Mr. Shao Hui, a pregnancy expert, has concluded that turpentia extract can promote blood circulation in the womb; taking it in the first trimester can also inhibit contractions by inhibiting prostaglandin secretion, prevent fetal arrest and miscarriage, and escort your pregnancy road!
