Overview
There are two isoforms of 5-alpha reductase named type 1 and type 2. Type 1 5-alpha reductase is found mostly in the skin and liver, which can get delivered to the prostate by systemic circulation. Type 2 is found only on prostatic tissue and is the most common form. So, 5-alpha-reductase deficiency is known as 5-alpha-reductase 2 deficiency.
