• Dutasteride and abiraterone were evaluated for inhibition of steroidogenesis. • Bypass mechanisms arise in the presence of abiraterone to form DHT. • Dutasteride inhibits T and DHT effectively in vitro. • Abiraterone inhibits AR and steroidogenesis leading to suppression of PSA. • Combining abiraterone and dutasteride activate compensatory mechanisms.
