Abstract

Hyperprolactinemia is the most common cause of hypogonadotropic anovulation and is one of the leading causes of infertility in women aged 25-34. Hyperprolactinemia has been proposed to block ovulation through inhibition of GnRH release. Kisspeptin neurons, which express prolactin receptors, were recently identified as major regulators of GnRH neurons. To mimic the human pathology of anovulation, we continuously infused female mice with prolactin. Our studies demonstrated that hyperprolactinemia in mice induced anovulation, reduced GnRH and gonadotropin secretion, and diminished kisspeptin expression. Kisspeptin administration restored gonadotropin secretion and ovarian cyclicity, suggesting that kisspeptin neurons play a major role in hyperprolactinemic anovulation. Our studies indicate that administration of kisspeptin may serve as an alternative therapeutic approach to restore the fertility of hyperprolactinemic women who are resistant or intolerant to dopamine agonists.

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

  • PRL infusions reduce kisspeptin and GnRH expression, resulting in anovulation.

    “In support of this hypothesis, PRL infusions have been shown to reduce the kisspeptin and GnRH expression, resulting in anovulation (27).”

    From Kisspeptin Overcomes GnRH Neuronal Suppression Secondary to Hyperprolactinemia in Humans (2022) · cites this paper as [27]

    The Results and Discussion report that PRL treatment decreased hypothalamic Kiss1 expression and was accompanied by anovulation. They also report inhibited GnRH release, but explicitly state that hypothalamic Gnrh gene expression was not altered. The claim therefore conflates reduced GnRH release with reduced GnRH expression. (LLM, conf=0.91)

  • In female mice with hyperprolactinemia, kisspeptin administration restores GnRH and gonadotropin secretion and ovarian cyclicity.

    “In female mice with hyperprolactinemia, kisspeptin administration was shown to restore GnRH and gonadotropin secretion and ovarian cyclicity (27).”

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.
