What are the features of the structure of the yellow body, and what functions does it perform?
The yellow body, which contains the ovary, usually does not exceed 10-27 mm. The size of it can vary depending on what phase of the menstrual cycle is currently taking place. With a decrease, or vice versa, an increase in the yellow body is larger than the above-mentioned dimensions, one speaks of its pathology.
The main, perhaps, function of this gland is the production of the hormone progesterone. Along with it, androgens, estrogens and oxytocin, as well as relaxin, inhibin and other biological substances, are produced in small amounts, which, first of all, are responsible for maintaining the pregnancy that has arisen.
What effect does the yellow body have on pregnancy?
The formation of a yellow body in the ovaries occurs after ovulation. There is not always. In case, after the release of the ovum from the ovary, it was never fertilized, the yellow body soon dissolves. In the case of pregnancy, it continues to exist in the ovary. It is at this point that the synthesis of progesterone, which is also called the "hormone of pregnancy," begins. Thanks to him, a fertilized egg recovers in the uterine cavity.
The operation of the gland continues until 10-16 weeks of gestation, i.ะต. until the placenta is fully ripe, and will not take on the function of producing the necessary hormones for the body. Therefore, the absence of a yellow body in the ovary puts the resulting pregnancy in jeopardy, and can lead to a miscarriage.
What are the most common disorders of the body?
There are 2 main problems that are most often observed in women and are associated with the functioning of the examined gland:
- low activity;
- cyst of a yellow body.
Both these conditions disrupt its normal functioning and in pregnancy can lead to miscarriage. That is why urgent correction is needed, which is carried out with the use of medications.
The main signs of having a yellow body cyst in the ovary are:
- painful sensations located in the region of the uterine appendages, in the left part of the abdomen or on the right;
- a constant sensation of feeling of bursting, discomfort, heaviness;
- the delay of menstrual bleeding, the violation of the cycle, the increase in the duration of menstruation due to uneven rejection of the endometrium.
To exclude the development of these pathologies, the doctor performs measurements of the size of the yellow body during ultrasound. If they exceed the norm, we can assume the presence of cysts in the yellow body, and further examination is aimed at the correct definition of its localization.
Also, a woman's health problems can arise even when the old yellow body in the ovary, after lack of fertilization, does not resolve. This can prevent subsequent menstruation, and often leads to the development of an inflammatory process in the ovary.
Thus, the yellow body takes a direct part in the normal course of the pregnancy process, allocating the necessary hormones and substances for this. That is why, with a long absence of pregnancy, to determine the causes of infertility in the course of diagnosis, a measurement of the size of the yellow body is performed, which allows to determine whether it is functioning correctly or correctly.
