Influence of Corticotropin-Releasing Factor on Reproductive Functions in the Rat*

RIVIER, CATHERINE, VALE, WYLIE·1984·Endocrinology

Abstract

The acute administration of 0.015-1.5 nmol ovine corticotropin-releasing factor (CRF) into the lateral ventricle of gonadectomized (or gonadectomized/adrenalectomized) female rats caused a rapid and prolonged dose-related inhibition of LH (but not FSH) secretion. By contrast, the acute peripheral injection of up to 15 nmol CRF was without effect in the same animal preparations. In cycling intact female rats, injection of 1.5 nmol CRF into the brain or of 75 nmol CRF sc inhibited ovulation and blocked the proestrous LH surge in about 50% of the animals. Lower doses of peripherally administered CRF were ineffective. Finally, CRF injected daily sc (15 nmol/day) to female rats during the first 12 days after mating caused a 40% disruption of pregnancy. These results indicate that CRF will lower plasma LH levels and can exert this effect in the absence of circulating steroids of either adrenal or gonadal origin. CRF inhibition of LH secretion, which we have previously reported to be absent in vitro, was unaltered by the opiate receptor antagonist naltrexone or by the ganglionic blocker chlorisondamine. Furthermore, blockade of CRF-induced beta-endorphin or ACTH release into the general circulation by dexamethasone did not interfere with the inhibitory effect of CRF on LH secretion. Such observations suggest that CRF exerts deleterious actions on reproductive functions through brain sites of action which, at least under the experimental mental design used, do not appear to directly…

Claims other papers make about this one

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

  • CRH injected daily to female rats during the first 12 days after mating caused a 40% disruption of pregnancy.

    “Additionally, CRH injected daily to female rats during the first 12 days after mating caused a 40% disruption of pregnancy [35].”
  • Acute administration of ovine CRH into the lateral ventricle of gonadectomized, adrenalectomized female rats produces a rapid and prolonged dose-related inhibition of LH (but not FSH) secretion.

    “In a study consisting of acute administration of ovine CRH into the lateral ventricle of gonadectomized, adrenalectomized female rats, a rapid and prolonged dose-related inhibition of LH (but not FSH) secretion was exhibited [35].”
  • Animal studies have linked increased corticotropin releasing factor (CRF) to decreased LH and FSH secretion and hypercortisolemia.

    “Animal studies have linked increased corticotropin releasing factor (CRF) to decreased LH [12,13] and FSH [12] secretion and hypercortisolemia.”
  • Direct implantation of CRF into the brain of rodents inhibits LH secretion, and peripheral infusion of CRF decreased LH and FSH secretion in the monkey.

    “Direct implantation of CRF into the brain of rodents was observed to inhibit LH secretion [13], and peripheral infusion of CRF decreased LH and FSH secretion in the monkey [12].”

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.
