Abstract

BACKGROUND: Ethanol intake levels characteristic of adult males and females emerge postpubertally. The present set of experiments examined the consequences of prepubertal and adult gonadectomies to explore whether the presence of gonadal hormones at puberty exerts organizational influences and/or plays an activational role in age- and sex-typical patterns of ethanol consumption. METHODS: Male and female Sprague-Dawley rats were gonadectomized (GX), received sham gonadectomy (SH), or were left nonmanipulated (NM) at 1 of 2 ages, either prepubertally on postnatal day (P) 23 (early) or postpubertally in adulthood on P70 (late). Early surgery animals were tested for ethanol consumption either during adolescence (P28 to 39) or in adulthood at the same age that late surgery animals were tested (P75 to 86). Voluntary ethanol consumption was indexed using a 2-hour limited-access paradigm, with access to 2 bottles: one containing water and the other a sweetened ethanol solution. RESULTS: Age of GX did not impact patterns of ethanol consumption. Removal of testicular hormones in males, regardless of age of removal, elevated consumption levels in adulthood to female-typical levels. Ovariectomy did not have notable effects on ethanol drinking in females. Ethanol intake and preference of early SH males were significantly greater than those of both late SH and NM males. Removal of the gonads prior to puberty did not influence ethanol drinking or preference during adolescence in either males or females. CONCLUSIONS: These results suggest that testicular hormones play an activational role in lowering ethanol intake and preference of adult male rats. Pubertal hormones, in contrast, were found to exert little influence on ethanol drinking or preference during adolescence, although the effect of surgical manipulation itself during development was found to exert a long-lasting facilitatory effect on ethanol consumption in adulthood.

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

  • Gonadectomy at either pre-pubertal or adult timepoint increases both ethanol preference and intake in male rats, and testosterone replacement in adulthood lowers ethanol preference to control levels.

    “In contrast, gonadectomy at either timepoint increases both ethanol preference and intake in male rats (Vetter-O’hagen and Spear, 2011), and testosterone replacement in adulthood (p77–93) lowers ethanol preference to control levels (Vetter-O’Hagen et al., 2011).”

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.
