Aromatization of Androstenedione by the Anterior Hypothalamus of Adult Male and Female Rats
Abstract
Homogenates of fresh tissue from adult male and female rats were incubated with appropriate co-factors and androstenedione-3H for one hour at 37° C. Extraction and identification of reaction products demonstrated the aromatization of androstenedione to estrone by anterior hypothalamus but not by posterior hypothalamus, anterior pituitary gland or frontal cortex. This finding confirms and expands the previous preliminary report of aromatization by human fetal hypothalamus to include adults of both sexes in a second species, the rat. Further localization of this reaction is consistent with concepts derived from experimental evidence which indicate central aromatization of androgens to be involved in sexual differentiation of the brain, initiation and maintenance of sexual behavior, control of gonadotropin secretion and “peripheral conversion” of circulating androgens to estrogens.

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.
