Understanding DHT: Normal vs Optimal Ranges

Also known as: dht, dihydrotestosterone

Male HormonesUnit: pg/mL

?What is DHT?

Dihydrotestosterone (DHT) is a potent androgen formed from testosterone by the enzyme 5-alpha reductase. DHT is approximately 3–5 times more potent than testosterone at androgen receptors. It plays a critical role in male genital development, prostate growth, and is the primary driver of male pattern baldness and benign prostatic hyperplasia.

!Why It Matters

Elevated DHT is associated with benign prostatic hyperplasia (BPH), male pattern hair loss (androgenetic alopecia), and prostate cancer development. 5-alpha reductase inhibitors (finasteride, dutasteride) block DHT production and are used to treat BPH and hair loss. Low DHT may occur during treatment with these medications.

Reference Ranges

Range TypeMinMaxUnitNote

Lab normal ranges may vary between laboratories. Optimal and longevity targets are based on research literature and should be interpreted with your physician.

Symptoms of Imbalance

  • High DHT: accelerated hair loss, urinary symptoms from prostate enlargement
  • Low DHT: reduced libido, erectile dysfunction, reduced body hair

How to Improve Your Levels

  • 1Finasteride or dutasteride reduce DHT (under medical supervision)
  • 2Saw palmetto may modestly reduce 5-alpha reductase activity
  • 3Zinc inhibits 5-alpha reductase activity
  • 4Maintain healthy testosterone levels through lifestyle

When to Test

When investigating male pattern baldness, BPH, or monitoring response to 5-alpha reductase inhibitor therapy.
