This study investigated the effects of social environment on gonadal recrudescence and sexual behavior in male and female Little Striped Whiptail lizards (Cnemidophorus inornatus). The presence of sexually active males facilitates ovarian recrudescence in conspecific females. Similarly, the presence of reproductively active females facilitates testicular recrudescence in conspecific males. Males housed with females, however, had lower average circulating concentrations of testosterone and dihydrotestosterone, and higher average concentrations of corticosterone compared to intact males housed in isolation. In other studies, the presence of reproductively active females partially restored courtship behavior in castrated males compared to castrated males housed in isolation. Despite the stimulatory effects of females on castrates, exogenous androgens are required for complete restoration of all components of sexual behavior in male C. inornatus. Females are receptive to male courtship and copulatory behavior only during the vitellogenic stages; females in previtellogenic or postovulatory ovarian stages aggressively reject male courtship advances. These findings demonstrate reciprocal effects of sexual behaviors of males and females upon each other's reproductive behavior and physiology.
本研究调查了社会环境对雄性和雌性细纹鞭尾蜥（Cnemidophorus inornatus）性腺复苏及性行为的影响。性活跃雄性的存在促进了同种雌性的卵巢复苏。同样，生殖活跃雌性的存在促进了同种雄性的睾丸复苏。然而，与单独饲养的完整雄性相比，与雌性生活在一起的雄性的睾酮和双氢睾酮平均循环浓度较低，而皮质酮平均浓度较高。在其他研究中，与单独饲养的去势雄性相比，生殖活跃雌性的存在部分恢复了去势雄性的求偶行为。尽管雌性对去势雄性有刺激作用，但对于雄性细纹鞭尾蜥性行为所有组成部分的完全恢复而言，外源性雄激素是必需的。雌性仅在卵黄生成阶段接受雄性求偶和交配行为；处于卵黄生成前或排卵后卵巢阶段的雌性会积极拒绝雄性的求偶行为。这些发现表明了雄性和雌性性行为对彼此生殖行为和生理的相互影响。
