A previous study reported plasma sex steroid levels were measured in female dab (Limanda limanda) induced to ovulate by injections of human chorionic gonadotrophin (HCG). In the present study, a similar experiment was carried out on male dabs. In common with female dabs, 17alpha, 20alpha -dihydroxy-4-pregnen-3-one and 3 beta, 17alpha, 20alpha -trihydroxy-5 beta -pregnane showed the greatest response. Their plasma levels increased, respectively, from 6 plus or minus 1.6 and 13 plus or minus 6.2 ng/ml to ca. 62 ng/ml within 36 hr and then decreased. Levels of both steroids remained low in fish injected with saline.
