title: Long term effects of a first pregnancy on serum concentrations of dehydroepiandrosterone sulfate and dehydroepiandrosterone.
abstract: A previous paper in this journal reported that first pregnancy was followed by a marked decrease in dehydro-epiandrosterone sulfate (DHAS) and dehydroepiandrosterone (DHA) levels. We report here confirmatory observations from cross-sectional measurements in 460 women. In premenopausal subjects (n = 306), the mean DHAS level was 21% lower (P = 0.005) and the mean DHA level was 32% lower (P less than 0.001) in parous than in nulliparous women. Neither DHAS nor DHA was related to parity in postmenopausal women (n = 154).
