Prolactin is a hormone synthesized and accumulated in the anterior pituitary gland, which plays an important role in the regulation of lactation in women after childbirth. It also stimulates the production of progesterone, which is necessary for the development of the placenta and the formation of the corpus luteum in the ovaries.
Prolactin is a lactotropic hormone, meaning it is responsible for milk production. Its production increases during pregnancy and after childbirth, which is necessary to maintain lactation. However, if prolactin levels are elevated, it can lead to the development of galactorrhea, an abnormal milk secretion that can occur in both men and women.
In general, prolactin plays an important role in human reproductive function and its production is regulated by the hypothalamus and pituitary gland. Dysregulation of prolactin can lead to various diseases such as galactorrhea, amenorrhea, infertility and others. Therefore, it is important to monitor prolactin levels in the body and consult a doctor if necessary.
The hormone prolactin is one of the most important hormones in the human body. Its synthesis is produced in the anterior lobe of the pituitary gland, which is located in the brain. Prolactin is a lactotropic hormone (lactogenesis hormone), which is responsible for the formation and secretion of breast milk. It is produced in women after childbirth and its level in the blood can vary significantly depending on various factors. In this article we will take a closer look at the hormone prolactin and its role in our body.

Introduction
***Prolactin*** is a hormone synthesized and accumulated in the anterior lobe of the ***pituitary***. It is responsible for ***secretion of milk*** in women after ***birth***, and also stimulates ***production of progesterone*** in the ***corpus luteum of the ovary***. With elevated levels of prolactin, the likelihood of developing ***abnormal secretion*** of milk increases in both men and women.
The effect of prolactin on the reproductive system
Early after birth, women's ***LH*** levels decrease (primarily in the brain). In response to this, against the background of ongoing physiological blockade of the hypothalamus and other brain structures, the level of ***prolactin*** secretion increases [2]. The mechanism of this increase in the mechanism has not yet been fully studied. There are suggestions that this mechanism is associated with the activity of progesterone receptors [3].
Until prolactin levels reach sufficient concentrations, breastfeeding does not begin. On days 5-6 after the start of breastfeeding, there is a sharp increase in the secretion of prolactin and a two-fold decrease in ***luteinizing hormone (LH)*** [4]. The level of ***follicle-stimulating hormone*** (FSH) remains constant during these periods. Gradually, one day after stopping breastfeeding, the level of prolactin decreases to the initial level (placental 3-monoxidase enzyme).
**Prolactin** is a hormone of the anterior pituitary gland, which is responsible for many processes in the body, such as growth and development, reproductive function, etc. However, one of the most important properties of prolactin is its ability to stimulate lactation after childbirth. In this article we will look in more detail at what lactotropic hormone is, how it works and what consequences a high concentration of this hormone in the body can have.
