Abstract

Prenatal handling, prenatal stress, and early postnatal exogeneous testosterone were examined in female rats for their effects on rat pup-killing and pup retrieval. During each of the last 5 days of pregnancy. Long-Evans rats received either 3 minutes of handling, 45 minutes of restraint and intense illumination or remained untouched. Half of the offspring of each group received testosterone from Day 1 after birth to Day 30. In adulthood, animals that received handling prenatally and testosterone postnatally killed pups more rapidly than any other group and a larger proportion did so than in the control groups. Animals not manipulated at any time retrieved pups more rapidly and a larger proportion did so than the combined other groups. The study suggests that prenatal handling interacts with testosterone presented immediately postnatally to increase infanticide in female rats. A variety of perinatal manipulations seem to suppress pup retrieval.

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.
