Disappearance Rates of Endogenous Follicle-Stimulating Hormone in Serum Following Surgical Hypophysectomy in Man

YEN, S. S. C., LLERENA, L. A., PEARSON, O. H., LITTELL, A. S.·1970·The Journal of Clinical Endocrinology & Metabolism

Abstract

The disappearance rates of endogenous FSH in serum following complete hypophysectomy were determined in 5 patients. Simultaneous determinations of serum FSH and LH were made in one patient. The hormone concentrations were measured by specific radioimmunoassays. Endogenous FSH disappears from circulation at a much slower rate than endogenous LH (approximately 10-fold). The disappearance rates for FSH, like that of LH, could be resolved into at least 2 exponential components. The initial fast component has a mean t½ of 3.9 hr, which was followed by a second slow component with a mean t½ of 70.4 hr.

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.
