Influence of ovarian and testicular secretions on lordosis was examined in 64 female hamsters ovariectomized when 1 or 43 days old and in 80 males castrated when 1, 3, 5, or 43 days old. The first of eight weekly 10-min mating tests was initiated at 57 or 113 days. Receptivity was not different among female groups except for higher initial scores for those with ovaries through puberty. Initial and maximum receptivity in males was inversely proportional to castration age. Rate of decrease from maximum appeared higher in males castrated at Days 3 and 5 than at Day 1. Age of initial test was significant for males; older animals had lower initial and maximum receptivity scores. Gonadal secretions decreased weights in both sexes.
在64只1日龄或43日龄时进行卵巢切除的雌性仓鼠以及80只1日龄、3日龄、5日龄或43日龄时进行阉割的雄性仓鼠中，研究了卵巢和睾丸分泌物对脊柱前凸的影响。八次每周10分钟的交配测试中的第一次在57日龄或113日龄开始。除了青春期有卵巢的雌性组初始得分较高外，各雌性组之间的接受性没有差异。雄性的初始和最大接受性与阉割年龄成反比。在第3天和第5天阉割的雄性，从最大值下降的速率似乎比第1天阉割的雄性更高。初始测试的年龄对雄性有显著影响；年龄较大的动物初始和最大接受性得分较低。性腺分泌物使两性的体重减轻。
