  • Red sea urchins, 10 months old, were fed for 30 days on a casein-based diet containing progesterone, androstenedione, testosterone, estrone, or estradiol-17{beta}. The mean gonad indices of male animals in the androstenedione-and the estrone-treated groups were significantly higher than those in the control group, suggesting that these steroids promote gonadal growth in male animals. Histological observations indicated that spermatogenesis in the estrone-treated group was also promoted compared… CONTINUE READING
