Abstract

In the study reported here, we investigated the effect of androgens on recruitment of resting, primordial follicles into the actively growing pool. Healthy, random-cycling female rhesus monkeys were treated with testosterone, dihydrotestosterone (DHT), or vehicle for 3-10 days, after which ovaries were collected for histological analysis. The first stage of follicle growth is the formation of the primary follicle, consisting of an oocyte surrounded by a single layer of cuboidal granulosa cells. The number of primary follicles was significantly increased over time in testosterone-treated animals. In situ hybridization showed that androgen treatment resulted in an increase to 3-fold in insulin-like growth factor I (IGF-I) and to 5-fold in IGF-I receptor mRNA in primordial follicle oocytes. DHT effects were comparable to those of testosterone, showing that these are androgen receptor-mediated phenomena. These data show that androgens promote initiation of primordial follicle growth and implicate oocyte-derived IGF-I in this activation process.

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.
