Hello,

I wanted to know why people say accutane causes erectile dysfunction? It is a Type 1 5AR inhibitor! Not type 2! 5AR type 1 has a very low expression in urogenital areas. Unlike finasteride. I took 2 courses of accutane (high dose) and I am still able to get an erection, still have morning wood, still have high libido... so whats the deal here? DHT is tissue dependent. The circulating DHT is irrelevant. and the DHT in the sexual dependent tissue remains unaffected by accutane. I think people reading that accutane leads to ED has a way stronger effect on development of ED than accutane itself
