ResumenFluctuations in the plasma concentration of estradiol, progesterone, and prolactin across pregnancy regulate maternal nest-building (digging, straw-carrying, and hair-plucking) and food intake in rabbits. Because testosterone levels also change through pregnancy, we investigated if the injection of testosterone propionate (TP; 1 or 5 mg/day) or 5alpha-dihydrotestosterone propionate (5 or 10 mg/day) for 20 days, alone and combined with progesterone (P; 10 mg/day from days 2 to 15), modulated nest-building and food intake in ovariectomized rabbits. Only the combined injection of TP (5 mg/day) plus P stimulated digging and no treatment promoted straw-carrying or hair-plucking. Both androgens induced hair-loosening from the ventrum, an effect counteracted by P. High doses of TP and 5alpha-dihydrotestosterone propionate reduced food intake by 60-70\% of baseline values; this effect was counteracted by P in TP-treated animals. These results support a participation of androgens in specific aspects of maternal nest-building and reveal a strong inhibitory effect on food intake. (C) 2003 Elsevier Science (USA).
