Prolactin hormone is responsible for milk secretion after parturition.

Prolactin hormone is responsible for milk secretion after parturition.

Prolactin is the most vital hormone, which controls reproductive health. This hormone is produced and secreted in the front portion of the pituitary gland present in the brain and is found in both males and females. Other than the pituitary gland, Prolactin hormone is also secreted by immune cells, skin, adipose tissue, breasts, and uterus. Prolactin is released by the respective glands when a newborn baby suckles the mother’s breast, causing the production of milk. Prolactin hormone is mainly involved in differentiating the cells that perform their own specific functions. This is a specialized hormone, which is mainly produced when the body is exposed to high levels of the  cortisol hormone  for a longer period of time. The Prolactin hormone plays a vital role in stimulating the alveoli, which is responsible for producing milk after the baby’s birth. Refer more:  Parturition – Childbirth

Prolactin is the only specialized hormone, which promotes lactation in mammals and is responsible for a number of other functions and systems. Listed below are a few of them:

The hormonal level in both male and female sex remains the same till they attain puberty. The level rises or increases 2 to 3 times during deep sleep and there is a peak in the early morning hours.

The increased level of prolactin hormone is mainly seen during pregnancy, stress, physical activities, breast stimulation and in nursing mothers. The decreased level of prolactin hormone is mainly because of hypopituitarism. The main disorders caused by the prolactin hormone are hyperprolactinaemia and hypoprolactinaemia Also Refer:  Hormones and Hormonal Disorders What is hyperprolactinemia? The condition of having more prolactin circulating in the blood is called hyperprolactinaemia. The causes of hyperprolactinaemia include:

What is hypoprolactinemia? The condition of having little prolactin circulating in the blood is called hypoprolactinaemia. This condition is very rare and may occur in people with underactivity of the pituitary gland and Sheehan’s syndrome. Reduced secretion of prolactin hormones leads to inadequate milk being produced after giving birth. There are no specific symptoms with a low level of prolactin hormone. The preliminary evidence suggests they might have reduced immune responses to some infections. The condition of having too little prolactin hormones in males results in oligospermia and visual disturbance.

PRL or prolactin test is the pathology test which is mainly used for the diagnosis of the level of prolactin hormone in an individual. The PRL test is also used for diagnosing:
