Prolactin is an important hormone involved in the production of milk by women at the same time that affects other functional activities of cells. Prolactin is also valuable in supporting the diagnosis and treatment of diseases of the functioning of reproduction of both sexes.

1. What is the hormone Prolactin?

Prolactin (PRL) is also known as luteotropic hormone or luteotropin, which is a protein that plays an important role in the production and secreting of milk. Prolactin was found in animals by the scientist Oscar Riddle in 1930, then in 1970 it was confirmed on humans by Henry Friesen.

Prolactin is produced from the antral lobe of the pituity glands and secreted in stages in order to meet the problems of eating, intersym, treatment related to estrogen, ovulation and the most important role is to stimulate milk production.

The secretion of prolactin of the piti pit gland is conditioned by the neurons of the ende noisy gland in the lower hills:

  • TIDA neurons: The most important cell of arc almonds that secrete dopamine (the hormone that inhibits the production of prolactin) acts on the D2 receptor of lactotrophs that inhibit the secretion of prolactin.
  • The hormone releases thyrotropin which stimulates the release of prolactin.

Prolactin has a molecular weight of about 22 – 23 kD, which is composed of 198 different types of amino acids. In serum, prolactin exists in 3 different forms:

  • Monosymic: 80%, is a form of biological activity and immunity.
  • Binary form :Accounts for 5 – 20%, this form has no biological activity.
  • Quadrilateralform : Accounts for 0.5 – 5%, which is a form of low biological activity.

Prolactin is found both in men and women, increasing in pregnant and lactation women.

Female: In non-pregnant women it is 2 – 29ng/ml, in pregnant and lactation women it is 10 – 209 ng/ml. Prolactin index in men: 2 – 18 ng/ml.

2. The role of the hormone Prolactin

Prolactin plays an important role in the body's metabolism, moderates the immune system and is directly related to the development of the pancreas.

Prolactin acts on the same mechanism as cytokines, which play an important role in:

  • Air conditioning of the immune system and metabolism of the body.
  • In relation to the process of cell growth.

What is the hormone Prolactin?

The role of the hormone Prolactin in relation to cell growth
  • Affects the process of cell chemistry.
  • Against cell-cycled death.
  • Prolactin has a profound effect on hematoma, procillary vascular pron prosy, and is also involved in the coaulation process.

The target body of prolactin is the mammary glands that promote the development of the mammary glands while at the same time distinguishing the mammary glands, stimulating the mammary glands to secrete after childbirth and then combining with oxytocin to push milk out. Some post-birth cases of insufficient lactation can also be caused by post-birth prolactin depleted.

In aeration, prolactin is also known as the yellow body nourishing hormone. It is directly related to the process of ovulation to the formation of menstruation and facilitates conception. Blood prolactin levels are inversely proportional to blood estrogen levels. When prolactin levels rise, it reduces the amount of estrogen. This means that it interferes with the estrogenic process from negatively impacting the lower axis of the hill – the sathala to increase LH secretion. When the hormone LH is not produced, there are no factors that provoke ovulation leading to amality, menstruation off and difficulty conceiving, infertility is rare.

Clinically, blood prolactin test results are relied on to support diagnosis and treatment. The blood prolactin index can help evaluate:

  • Evaluation of the function of the sath line or diseases of the sysath gland.
  • Diagnosis of the causes of genital problems in both men such as infertility, asym neurorrmenity, menstrual disorders, premature dysaculation, erectile dysfunction,…
  • Helps diagnose and support the treatment of tumors such as mammary gland tumors, pit gland tumors or tumors that increase prolactin production …

Prolactin is an important hormone involved in the production of milk by women at the same time that affects other functional activities of cells. Prolactin is also valuable in supporting the diagnosis and treatment of diseases of the functioning of reproduction of both sexes.
