5-Alpha Dihydrotestosterone (DHT) is a blood test that measures the level of DHT, a potent androgen produced from testosterone by the enzyme 5-alpha reductase. DHT plays an important role in male sexual development, prostate function, and hair growth. The test is needed to evaluate certain hormonal or androgen-related disorders, including abnormal sexual development, unexplained hair changes, or suspected abnormalities in testosterone metabolism.
DHT is a hormone produced when the enzyme 5-alpha reductase converts testosterone into a more potent androgen that influences several male characteristics and tissues.
DHT contributes to male sexual development, prostate growth, body hair development, and other androgen-dependent functions in both males and females.
Yes. DHT is strongly associated with androgenetic alopecia (pattern hair loss) in genetically susceptible individuals, although hair loss can have many different causes.
Elevated DHT levels may be associated with androgen-related symptoms such as increased body hair, acne, scalp hair thinning, or other hormonal changes depending on the individual.
Low DHT levels may occur in conditions affecting testosterone metabolism, including deficiencies of the enzyme 5-alpha reductase or certain hormonal disorders.
