5α-Reductase - Wikipedia
5α-Reductases, also known as 3-oxo-5α-steroid 4-dehydrogenases, are enzymes involved in steroid metabolism. They participate in three metabolic pathways: bile acid biosynthesis, androgen and estrogen metabolism. There are three isozymes of 5α-reductase encoded by the genes SRD5A1, SRD5A2, and SRD5A3.

2023年7月18日 · The class of medicines called 5-alpha reductase inhibitors (5ARIs) includes finasteride and dutasteride. These medicines treat benign prostatic hypertrophy and male pattern hair loss.
5-Alpha Reductase Deficiency: How It Affects Hormones
2023年4月27日 · 5-alpha-reductase deficiency is a rare hereditary disorder caused by the mutation of the SRD5A2 gene. It is an autosomal recessive mutation, meaning that you can only get it if both of your parents pass an SRD5A2 gene mutation to you. There are more than 60 different mutations that can cause this.

5-Alpha Reductase - an overview | ScienceDirect Topics
5-Alpha reductase is the enzyme responsible for the conversion of testosterone into 5-alpha dihydrotestosterone (DHT), a potent androgen involved in male sexual differentiation. In the absence of DHT, undermasculinized external genitalia are observed; in severe enzyme deficiency, patients may be phenotypically female [176] .
