Low Dihydrotestosterone (DHT): what it means
A Dihydrotestosterone (DHT) result below the normal range is considered low. Here is what a reduced Dihydrotestosterone (DHT) can point to, and when it is worth discussing with a doctor.
Reference range: ~30–85 ng/dL in men (much lower in women); the most potent androgen, made from testosterone — drives hair-follicle effects, prostate growth and male sexual development
Understand your full resultWhat a low Dihydrotestosterone (DHT) can mean
- 5-alpha-reductase deficiency — an inherited inability to convert testosterone to DHT, affecting male sexual development.
- Treatment with a 5-alpha-reductase inhibitor — the expected, intended effect of these drugs for prostate enlargement or hair loss.
- Low testosterone (hypogonadism) — less substrate to convert.
When to discuss with a doctor
DHT is a specialist test, not part of a routine hormone panel — testosterone is the usual measure of androgen status. DHT is checked in specific situations: assessing certain disorders of sexual development or a suspected 5-alpha-reductase deficiency, monitoring the drugs used for prostate enlargement or hair loss that block DHT, and occasionally as part of working up androgen excess causing hirsutism or hair loss. Because it is made and acts largely within tissues, a blood DHT does not always capture what is happening at the hair follicle or prostate, so it is interpreted carefully and alongside testosterone. Mediora.AI shows DHT alongside testosterone, free testosterone and SHBG so the androgen pattern reads together; the interpretation belongs with your doctor or endocrinologist.
