Seasonal reproduction in the mongoose, Herpestes auropunctatus

摘要: The male mongoose is a seasonal breeder and displays distinct pattern in serum androgen levels. In this series of experiments testicular responsiveness to luteinizing hormone (LH) was evaluated during the breeding (active) inactive seasons. testes LH assessed by measuring [125I]hCG (human chorionic gonadotropin) binding dispersed interstitial cells vitro LH-stimulated release cells. data indicated that there significantly greater concentration LHhCG sites/Leydig cell active season than season. contrast, prepared from animals trapped seasons were equally responsive small doses (“physiological”) ovine (oLH); however, higher oLH produced significant depression output but not These results indicate are differences responses testis LH. Whether levels directed changes gonadotropin or discussed.
