Effects of gonadectomy and gonadal steroid hormones on feeding. Males (♂) eat more than females (♀), but gonadectomy (\) had the opposite effect: castration of males resulted in weight loss because of decreased eating, while castration of females increased body weight due to hyperphagia. These changes were restored by testosterone (T) and estrogen (E) replacement, respectively.
