A new method was created to test the effectiveness of Dihydrotestosterone (DHT) inhibitors, like finasteride and dutasteride, in human and fish cells. The results showed fish cells are more sensitive to these treatments, and dutasteride works better than finasteride in all tested cells.

The 3D-SeboSkin model effectively simulates Hidradenitis suppurativa and is useful for future research.
