# What does a high Free Testosterone mean?

> High free testosterone means more of the hormone is unbound and active. In women it is the most sensitive lab clue to PCOS or, when marked, an adrenal or ovarian source; in men it usually reflects testosterone therapy or a low SHBG (obesity, insulin resistance) rather than overproduction. It is interpreted with total testosterone and SHBG together.


## When does this result need same-day care?

- Rapid virilization in a woman (deepening voice, clitoral enlargement, sudden hair growth) — prompt evaluation for a hormone-producing tumor

## What is the normal range for Free Testosterone?

- Male, age 18+: 47.0 – 244 pg/mL
- Female, age 18+: 0.100 – 6.40 pg/mL



## What are the common causes of high Free Testosterone?

1. Women: PCOS (most common), congenital adrenal hyperplasia, androgen-secreting tumors (rare, usually very high)
2. Low SHBG from obesity, insulin resistance, hypothyroidism or anabolic steroids — raises free T even with a normal total
3. Testosterone or DHEA supplements and therapy
4. Men: exogenous testosterone or anabolic steroids

## What symptoms go with high Free Testosterone?

- Women: acne, oily skin, excess facial or body hair, scalp hair thinning, irregular periods
- Men: often none; acne, irritability or reduced fertility on therapy

## What do clinicians usually check next?

- Total testosterone and SHBG to explain the pattern
- Women: DHEA-S, 17-hydroxyprogesterone, LH/FSH; pelvic ultrasound if PCOS is suspected
- Fasting insulin/A1c — insulin resistance is the usual driver of low SHBG
- Repeat on a morning sample; free testosterone assays vary, so trends within one lab matter most

## Common questions

### Why is my free testosterone high but total normal?

Because SHBG is low — less binding protein leaves more hormone free. Obesity and insulin resistance are the usual reasons; treating those raises SHBG.
