A diphasic pattern of gonadotropin secretion in patients with the syndrome of gonadal dysgenesis

Abstract

Cross sectional and longitudinal studies of plasma FSH and LH in 58 patients, age 2 days of 20 yr, with the syndrome of gonadal dysgenesis show a diphasic pattern of gonadotropin secretion. The mean basal plasma FSH level is 43 plus or minus 7 (SE) ng/ml (LER-869) in patients from 2 days to 4 yr, which is strikingly elevated. Thereafter, a decline in plasma FSH to a mean level of 4 plus or minus 0.7 (SE) ng/ml occurs between 4 and 10 yr, followed by a rise after 10 yr to 61 plus or minus 4 (SE) ng/ml. The pattern of LH (LER-960) secretion is qualitatively similar to that of FSH, although quantitatively the values for LH are 1/3 to 1/10 those for FSH. The similarity of pattern of gonadotropin secretion observed between patients with gonadal dysgenesis and normal children suggests that gonadal function does not play a decisive role in the pattern of gonadotropin secretion from infancy through adolescence, but exercises striking effects on the quantity of gonadotropin secreted.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Circulating concentrations of both FSH and LH present a biphasic pattern in Turner syndrome individuals with hypogonadism: elevated after birth, declining to values similar to girls with normal ovarian function during mid-childhood, and rising again in the peripubertal years or at the time of loss of ovarian function.

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.
