Dihydrotestosterone (DHT) · low result
What does a low Dihydrotestosterone (DHT) mean?
Short answer
Low DHT is expected in anyone taking finasteride or dutasteride, which block the enzyme that makes it; those drugs lower DHT by 60–90% and that is the therapeutic goal. Without such medication, low DHT tracks low testosterone (hypogonadism) or, rarely, an inherited 5-alpha-reductase deficiency. It is interpreted with total testosterone.

Common questions
I take finasteride — is my low DHT a problem?
No, it's the intended effect. Discuss with the prescriber only if you have side effects you want to weigh against the benefit.
