Steroid and steroid glucuronide synthesis in feral male African catfish was investigated in vitro by incubating testes with [ 3H]-pregnenolone and seminal vesicles with [ 3H]-androstenedione. In testes, the capacity to form progestins, androgens, especially 11-oxygenated ones, and steroid glucuronid...
