Prolactin (also known as lactogenic hormone, luteotrophic hormone, and luteotrophin) is a hormone secreted by the anterior pituitary gland (an endocrine gland in the human body).

The actions of prolactin in women include:

  • Stimulating the production of progesterone in the ovaries.
  • Stimulating milk production after childbirth.

The effects of excessive prolactin in both men and women can include:

  • Abnormal production of milk (called galactorrhoea).
