In Utero Proximity of Female Mouse Fetuses to Males: Effect on Reproductive Performance during Later Life

Vom Saal, Frederick S., Bronson, F. H.·1978·Biology of Reproduction

Abstract

Female mice were delivered by Caesearian section, with females between 2 male fetuses in the uterus (2M females) and females not contiguous to males in the uterus (OM females) being compared morphologically, physiologically and behaviorally during later life. The results reveal that 2M females are masculinized morphologically and behaviorally relative to 0M females; 2M females have a larger anogenital space, are more aggressive in a variety of different situations, are less effective at inhibiting male-induced puberty when group housed and urine mark their environment at higher rates (all masculine traits). On the other hand, 0M females are more sexually attractive and arousing to males than are 2M females. While no differences were noted between 0M and 2M females in terms of their sensitivity to gonadal steroids or in their capacity to produce and raise healthy young in an optimal laboratory environment, the data indicate that in utero contiguity to male fetuses produces a masculine bias in the transmission of and response to reproductively important social cues. Such a bias could alter the probability of mating and of successfully producing healthy offspring in a natural environment.

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.
