Abstract
A total of 230 healthy women attending family planning clinics took part in a cross-sectional study, comparing contraceptive histories and serum prolactin levels. The distribution histogram of serum prolactin was markedly skewed to the right in all main groups but the distribution profile was not affected by use of estrogen-containing contraceptives. Neither the dose of estrogens nor duration of their use affected prolactin levels. Evidently currently available combined oral contraceptive agents have no effect on serum prolactin. Analysis of the skewed raw data yields a normal range of 110-700 mU/l, higher than that usually accepted.
