The incidence of breast secretions in a group of normal women was studied. No secretions were found in women who had never been pregnant, but were fairly common in those who had been gravid at one time. Usually the women were unaware of the presence of these secretions. The incidence of secretions in women taking oral contraceptives was less than in those not taking such medication. This investigation indicates that galactorrhea in an apparently normal nulligravida may be very significant, whereas a similar finding in a woman who has been pregnant in the past may have no clinical importance. It also suggests a lack of a causal relationship between oral contraceptives and galactorrhea. © 1969.
