Abstract
In ovaries of the African catfish, Clarias gariepinus, uridine diphosphoglucose dehydrogenase (UDPGD) and 3β-hydroxysteroid dehydrogenase (3β-HSD) appear in the granulosa of post-ovulatory follicles. In testes, both enzymes are present in interstitial cells. The combined presence of UDPGD and 3β-HSD points to the formation of steroid glucuronides at these sites. Interstitial
