The original adaptive significance of milk secretions may have been nutrition or immunological protection.

Neonatal milk secretion is considered a normal variation and no treatment or testing is necessary.

This increases prolactin production and, therefore, milk secretion.

In women the monthly cycles become irregular or stop altogether, and during lactation milk secretion may become insufficient for the baby.

It is supposed to promote diuresis and milk secretion, activate blood circulation and relieve swelling.

Galactorrhea hyperprolactinemia is increased blood prolactin levels associated with galactorrhea (abnormal milk secretion).

Alternatively, the behavior may be a remnant of a newborn's kneading of the mother's teat to stimulate milk secretion.

In extremely rare cases neonatal mastitis may develop but it is unclear if it is related to neonatal milk secretion.

In this combined control from ECM and systemic hormones, milk secretion can be reciprocally amplified so as to provide enough nutrition for the baby.

Medicines for various health issues such as anaemia, infections, constipation, improved milk secretion and quick resolution of uterus for new mothers, and deworming medication are distributed regularly.

During his time at Berlin University, Michaelis worked in the lab of Oskar Hertwig, even receiving prize for a paper on the histology of milk secretion.

He obtained a PhD in 1993 and the title of his thesis is "Tissue distribution and milk secretion of 131 I in ruminants following their experimental exposure".

It is an extremely rare condition and believed to be in many cases related to an autoimmune reaction to milk proteins following incomplete inhibition of milk secretion and hyperprolactinemia.

This occurs, for the fat portion of the milk, by apocrine secretion, where vacoules containing materials bud off the cell into the lumen (storage) of the alveolus (milk secretion gland).

In Thai medicine the leaves and root are known to be diuretic; and used for treatment of intestinal infections and kidney dysfunction; when boiled or ground with water, it is take to increase milk secretion for post-labor.

A doctor will test for prolactin blood levels in women with unexplained milk secretion (galactorrhoea) or irregular menses or infertility, and in men with impaired sexual function and milk secretion.

Milk secretion (lactation) begins a few days later due to reduction in circulating progesterone and the presence of another important hormone prolactin, which mediates further alveologenesis, milk protein production, and regulates osmotic balance and tight junction function.
