Abstract

Context: Studies in humans and animals indicate that estrogen negative feedback occurs at the level of the hypothalamus, but it is unclear whether estrogen also exerts an inhibitory effect directly at the pituitary. Objectives: The aim of the study was to determine whether estrogen has a direct negative feedback effect at the pituitary and whether this varies with aging. Design and Setting: A GnRH antagonist and graded doses of GnRH were used to isolate pituitary responsiveness before and after estrogen administration in Clinical Research Center studies at an academic medical center. Subjects: Subjects were healthy postmenopausal women aged 48–56 yr (n = 8) or 70–75 yr (n= 8). Interventions: A suppressive dose of the NAL-GLU GnRH antagonist was administered, followed by graded doses of GnRH before and after 1 month of estrogen administration. Results: LH and FSH responses to GnRH decreased after estrogen administration (P = 0.01 and P = 0.0001, respectively). The ratio of FSH to LH amplitudes decreased in response to estrogen (P = 0.04) indicating a greater sensitivity of FSH than LH to inhibition by estrogen. The inhibitory effect of estrogen on FSH was attenuated with aging (P = 0.02), but was maintained for LH (P = 0.4). Conclusions: Studies that control for endogenous GnRH and estradiol demonstrate a direct pituitary site of estrogen negative feedback on LH and FSH responsiveness to GnRH in women. The effect of estrogen on FSH responsiveness is greater than on LH and is attenuated with aging. These studies indicate that estrogen negative feedback occurs directly at the pituitary and contributes to the differential regulation of FSH and LH secretion.

  • FSH release is stimulated by the active GnRH receptor complex and inhibited by the amount of E2.

    “The release of FSH from the pituitary, Rel FSH t ð Þ, is stimulated by the active GnRH receptor complex, GR a t ð Þ and inhibited by the amount of E2 (Shaw et al., 2010).”

    The Results section, “Effect of estrogen on LH and FSH responses to GnRH” (page unavailable), reports that FSH responses increased with GnRH dose and decreased after estrogen administration. The paper supports those directions of effect, but it does not directly measure an active GnRH receptor complex or establish how FSH release varies with the amount of E2. (LLM, conf=0.82)

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.
