Serum Androstenedione and Testosterone Levels During the Menstrual Cycle

JUDD, HOWARD L., YEN, SAMUEL S. C.·1973·The Journal of Clinical Endocrinology & Metabolism

Abstract

Utilizing specific radioimmunoassays serum androstenedione, testosterone, follicle stimulating hormone (FSH), and luteinizing hormone (LH) were measured daily in the same aliquots of sera in 6 ovulatory menstrual cycles. In 3 of 6 cycles a progressive increase in serum androstenedione concentration was seen during the follicular phase. The mean androstenedione level during the middle third of the menstrual cycle was significantly higher than during the earlier (p < 0.01) or later (p < 0.001) portions. Serum testosterone levels in the same individual cycles showed random variations. Again the mean T level was significantly higher (p < 0.001) during the middle third as compared to either the beginning or end of the menstrual cycle.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
