哺乳类的生殖过程中,乳汁分泌与排卵——妊娠——分娩现象,同样具有重要的意义。乳汁分泌的生理过程,通过鼠、豚鼠等实验动物或牛、猪、羊等家畜的研究,已趋明瞭。然而,人类的乳腺发育、乳汁分泌的生理过程和乳汁漏出症的生理。在过去,因为缺乏精确测定血中催乳素的方法,加之在生长激素(GH)以外是否还存在催乳素还 Mammals reproductive process, milk secretion and ovulation - pregnancy - childbirth phenomenon, also of great significance. The physiological process of milk secretion, through rats, guinea pigs and other experimental animals or cattle, pigs, sheep and other livestock research, has become clear.

In the past, because of the lack of a precise method of determining prolactin in the blood, combined with the presence of prolactin in addition to growth hormone (GH)
