This can express itself by milk river from the breast gland, even if the woman did not bear a child. In addition frequently the rule is missing with increased prolaktin.

Women after the change years < 15 480
Men < 15 480
In which cases is Prolaktin value too low?
To small Prolaktin quantities are with a subfunction of the gland of appendix of brain (hypophysis insufficiency) and with a over therapy with certain medicines (Dopaminagonisten).
