Leptin Treatment Rescues the Sterility of Genetically Obese ob/ob Males*
Abstract
Leptin, a hormone secreted from white adipose tissue, has been shown to normalize the body weight of ob/ob but not db/db mice as postulated by Coleman in his classical parabiosis experiments. The major effect of leptin is therefore to decrease food intake, thus resulting in a breakdown of fat stores. Recently, we have suggested that leptin plays a role in reproductive physiology based on the observation that leptin treatment but not food restriction rescues the sterility of ob/ob females. In the present communication, we treated sterile ob/ob males with leptin and asked whether fertility could be induced, thus selecting their reproductive ability as the endpoint of the experiment. Our results show that all food-restricted ob/ob males are unable to impregnate normal C57BL/6J females. However, all leptin-treated ob/ob males fertilized normal females mice that carried out normal pregnancies and deliveries, demonstrating that the reproductive capacity of ob/ob males was corrected only with leptin treatment. Furthermore, reproductive indices such as testicular weight and histology are normalized in leptin-treated animals. Therefore, as in ob/ob females, leptin plays a significant role in the male mouse reproductive pathways.

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.
