Dihydrotestosterone: normal range and what it means
Short answer: The normal dihydrotestosterone range is 30 – 85 ng/dL for men and 5 – 30 ng/dL for women. In SI units that is about 1 – 2.9 nmol/L for men and 0.2 – 1 nmol/L for women. Labs differ a little, so also check the range printed on your report.

A potent androgen derived from testosterone.
Normal range
This marker’s healthy range depends on sex and age.
| Normal range | Men | Women |
|---|---|---|
| Low | < 30 ng/dL | < 5 ng/dL |
| Normal | 30 – 85 ng/dL | 5 – 30 ng/dL |
| High | ≥ 85 ng/dL | ≥ 30 ng/dL |
What it measures
A more potent product of testosterone, made in tissue rather than the testes. It drives male-pattern hair loss and prostate growth more than testosterone itself does.
What moves it
Derived from testosterone via 5-alpha-reductase, so it follows testosterone and is strongly affected by medications that block that enzyme.
How to bring it into range
Mostly relevant when investigating hair loss or prostate symptoms. Interpreted with testosterone rather than alone.
How fast it responds
Weeks.

Common questions
- What is the normal dihydrotestosterone range?
- The normal dihydrotestosterone range is 30 – 85 ng/dL for men and 5 – 30 ng/dL for women. In SI units that is about 1 – 2.9 nmol/L for men and 0.2 – 1 nmol/L for women. Labs differ a little, so also check the range printed on your report.
- What does a high Dihydrotestosterone mean?
- A value above the reference band means Dihydrotestosterone is outside the range typical for a healthy adult. A single reading is rarely conclusive on its own — what matters is the trend across draws and the other markers around it, which is why HealthOS reads the whole panel together rather than one number at a time.
- How do I improve my Dihydrotestosterone?
- Mostly relevant when investigating hair loss or prostate symptoms. Interpreted with testosterone rather than alone.
