The onset of pregnancy triggers a number of biochemical processes in the female body that are necessary for the preservation and successful development of the fetus. One of the mechanisms that are needed for this is the yellow body.
What is the yellow body?
The yellow body is a temporary endocrine gland that is located in one of the ovaries. It is formed from the follicle that released the egg, and its main function is the production of hormones, primarily progesterone, responsible for the development of pregnancy. The yellow body is formed every time ovulation occurs, but by the end of the cycle it fades and is reduced, the ovary is preparing for a new cycle and a new ovulation. If the pregnancy is completed, the yellow body will be responsible for its development within the next 10-12 weeks, and then the placenta will take over the function of producing progesterone.
Yellow body - a sign of pregnancy
The presence of a yellow body in one of the ovaries can indeed be considered as an additional sign of pregnancy. But only in conjunction with other symptoms. The fact that outside of pregnancy in the ovary can, for various reasons, there is a cyst of the yellow body, which can also be diagnosed on ultrasound. Yellow body cyst as a sign of pregnancy may not be noted during the study, so only this factor should not be relied upon. The yellow body does not ache during pregnancy and does not manifest itself in any way.
In some cases, if ovulation occurs immediately in two ovaries, two yellow bodies appear during pregnancy. If the fertilization of both cells is successful, then twins will be born. However, the yellow body with a double can be one, because the twins are both monotonous and raznoyaytsevye.
Malnutrition in pregnancy
Hypofunction of the yellow body is a serious complication, which can threaten the interruption of pregnancy. Among the signs - smearing discharge, bleeding, tone, detachment of the fetal egg, detected by ultrasound. Hypofunction of the yellow body in pregnancy, confirmed by special studies, including the analysis of blood levels of hormones, is corrected with the help of drug therapy. A pregnant woman is prescribed a hormone progesterone, or rather his plant analogue in a dosage form. With the correct admission and carefully calculated dose, if there are no other reasons for interruption, pregnancy normally develops and ends with childbirth. Do not confuse the absence of a yellow body during pregnancy for ultrasound, which can not always be considered on low-resolution devices, and hormone deficiency confirmed by the doctor.
Pathological cases
Unfortunately, not always pregnancy can proceed smoothly, there are also pathological situations. So, the yellow body with ectopic pregnancy produces a significantly lower level of hormones, which allows you to suspect early pathology - it is enough to pass a blood test on hCG twice and track the dynamics of its growth,
The yellow body with a stopped pregnancy in general ceases to produce hormones, when the blood test is repeated, a decrease in the level of hormones is observed, ultrasound does not reveal signs of pregnancy.
The yellow body in the ovary for pregnancy has a direct effect. It is responsible for the development of the embryo and the formation of the placenta. That is why ultrasound in pregnancy yellow body, as a rule, look, and in the analyzes reveal the level of progesterone. To become pregnant with a yellow body, if it is a question of a cyst, is also possible, since ovulation can occur in another ovary.
