Nonpuerperal breast secretion. Its relation to the use of oral contracetpives.

The occurrence of breast secretion more than 1 year postpartum was studied in 800 healthy, parous women of childbearing age. Among of 418 women who were using a combination-type oral steroid contraceptive, the incidence of breast secretion was lower than among the nonusers. The incidence of bilateral secretion decreased with increasing duration of use of the oral contraceptives. Statistical material is presented for the incidence of breast secretion as related to age. time elapsed since last delivery, and duration of nursing the last child. Brownish secretion rather than white or yellowish is seen more often in women over 30 years of age. Various menstrual irregularities (excluding amenorrhea) do not appear to be associated with an increased incidence of breast secretion.
