Chorionic gonadotropin

Chorionic gonadotropin: what it is and how it affects the body

Human chorionic gonadotropin (HCH) is a hormone produced by the placenta in pregnant women. It got its name due to the fact that its discovery was associated with the study of the chorion, the membrane that surrounds the embryo inside the uterus.

HCH is a glycoprotein consisting of two subunits - alpha and beta. The alpha subunit is similar to that found in other hormones such as gonadotropins, thyrotropin, and corticotropin. The beta subunit is specific for HCH and provides its biological activity.

One of the main functions of HCH is to maintain the corpus luteum in the ovaries, which continues to produce progesterone, a hormone that is necessary to maintain pregnancy. In addition, HCH also stimulates the synthesis of estrogens in the placenta.

It is important to note that in women who are not pregnant, the level of HCH in the blood is low. However, in men, this hormone is also present in the body, although its functions are not yet fully understood.

HCH is used in medicine as a marker of pregnancy. The level of this hormone in the blood begins to increase in the early stages of pregnancy and reaches its peak in mid-pregnancy. Therefore, testing HCH levels can help determine whether a woman is pregnant.

In addition, HCH is used in the treatment of certain diseases such as delayed puberty and some forms of infertility. In these cases, HCH can stimulate the ovaries and increase the chance of conception.

In conclusion, human chorionic gonadotropin is an important hormone that plays a key role in maintaining pregnancy and reproductive function. Its level in the blood can be used to determine whether a woman is pregnant, as well as to treat certain diseases associated with the reproductive system.

Gonadotropin chorionic is one of the main glycoproteins of the allofibrin fraction of the human body. Along with other hormones, it is produced into the blood by the cells of the chorionic placenta, which is formed after the implantation of a fertilized egg into the wall of the uterus.

Gonadotropins are female sex hormones, i.e. estrogens and gestagens, as well as a substance that influences the formation of hereditary memory.

The ovary, uterus and kidney produce a hormone called luteinizing hormone (LH), a deficiency of which can cause amenorrhea. LH stimulates the production of progesterone synthesized in second-order granulosa cells of the ovarian follicles. Progesterone forms a protective shell
