Gonadal steroid hormone patterns in saddleback wrasses are paralleled by differences in gonadal ultrastructure and steroid hormone synthetic capacity. Females exhibited greater gonadal E2 synthetic capacity than advanced sex changers in vitro when stimulated by salmon gonadotropin, while terminal phase males showed greater 11KT synthesis than females in vitro with advanced sex changers being intermediate .
