The thin thickness of the lining of the uterus varies with age and menstrual cycles under the action of female sex hormones. The lining of the uterus is thin after menstruation and in men's women, the mucous membranes are thick in pregnant women and the second half of the menstrual cycle.
1. What is the endocosa of the uterus?
The endocosa of the uterus, also known as the lining of the uterus, is essentially a cell lining the uterus, composing of this mucous layer consisting of 2 layers: the endocosal layer and the bottom layer
- The endoratical layer is the layer that changes with the menstrual cycle.
- The bottom layer does not change with the menstrual cycle.
Endometrial is important for deciding the conception and nesting of fertilized eggs. The endometrial layer has a nutritional and protective effect, helping the pregnancy to develop best. The endometrial layer of the uterus thickens at the end of the menstrual cycle in preparation for fertilized eggs into nesting, if there is a phenomenon of conception this mucous layer will increase thicker. Without conception, under the sudden decrease of the endotriosis female sex hormone peels off and forms menstruation.
2. How does the endocosa of the uterus change during the menstrual cycle?
The endocosa of the uterus changes with the menstrual cycle under the action of the sysatal and ovarian hormones. The modified lining of the uterus can be divided by the menstrual cycle into 2 stages: the period of birth and the stage of excretion.
- Period of birth
After menstruation, the lining of the uterus peels off and forms menstruation, at which time the lining of the uterus remains only a thin layer about 3-4mm thick. Due to the end of the cycle the content of the hormones estrogen and progesterone decreases abruptly causing menstruation and produces a negative reverse conditioning reaction to the sedate glands that stimulate the ovaries to increase the excretion of these 2 hormones. Under the action of the hormone estrogen the endometrial cells begin to rise rapidly. The surface of the lining of the uterus thickens, blood vessels also increase. By the end of the period of increase in the thickness of the lining of the uterus at about 7-8mm
- Excretion stage
Under the action of the hormone the lining of the uterus is constantly increasing in the second half of the menstrual cycle, the lining of the uterus increases to about 8-12mm. Before the day of menstruation 2 days due to the sudden increase in the amount of hormones, the lining of the uterus thrives, at which time the thickness of the lining of the uterus can be about 12-16mm thick.
Then if there is no conception, the hormones estrogen and progesterone decrease suddenly, which causes the uterus blood vessels to contract the unnutrient lining of the uterus so they peel off and form menstruation. The lining of the uterus continues to grow with the upper cycle.
3. Endometrial abnormalities
Normally the lining of the uterus is about 7-8mm thick, after menstruation is 3-4mm, between and at the end of the menstrual cycle the thickest is about 8-15mm. From normal indicators that vary with the menstrual cycle can determine the condition of the thick lining of the uterus or the thin lining of the uterus.
- Thin lining of the uterus or thin endoometrial
Is when the mucous layer has a thickness of less than 6mm and not on the day of menstruation. When the lining of the uterus is thin the conception becomes difficult because the embryo cannot cling to the uterus for nesting. In some cases the lining of the uterus is thin, fertilized eggs can still nest and form the fetus, but due to being too thin, the mucous layer is not capable of providing enough nutrients to feed the developed fetus. Therefore, it will also affect the development of pregnancy, pregnancy is difficult to develop or can lead to miscarriage, still pregnancy.
Some of the causes that can cause a thin endo endo will such as: Low levels of estrogen in the body; Due to diseases related to the uterus such as tumours, inflammation …; Multiple abortions; Due to complications after procedures or surgeries in the uterus leading to sticking to the lining of the uterus …
- Thick lining of the uterus or thick endoometrial
That's when the lining of the uterus is over 20mm thick. For women with such endometrial strengthening, there is often a state of menopause, secondary arrhythmicity, ovule ejecting disorders. In this case, the ability to conceive is difficult because the thick mucous membrane interferes with the sperm meeting the egg.
Causes of thick endometriality include: The main cause of hormonal imbalances in the hormone estrogen in the body increases more than progesterone leading to proogenous proogeny of the lining of the uterus; Suffers from polycystic ovary disease; Due to the use of drugs containing estrogen constantly without progesterone.
Each time of the menstrual cycle, the thin thickness of the lining ofthe uterus is different , so when the uterus ultrasound at different times will see that the thin thick endotriosis is not the same. However, some cases of endometrials that are too thin or too thick to affect fertility should go to a specialized facility for examination and advice.
