Reproductive activity of male Rhabdomys pumilio is inhibited by exposure to a combination of reduced ambient temperature and food availability. However, the extent of this inhibition is reduced in mice that have maintained a body fat reserve. To determine if body fat stimulates reproduction via leptin, we treated 5 non-scrotal mice with exogenous leptin (40 micrograms subcutaneously twice per day for four days). A further 5 mice served as untreated controls. To determin...
