Understanding Free Testosterone (FTT)

Free Testosterone (FTT) is a key biomarker in blood tests that free testosterone measures the bioavailable form of testosterone, crucial for metabolic and reproductive health.

What is Free Testosterone?

Free Testosterone measures the bioavailable form of testosterone, crucial for metabolic and reproductive health.

Normal Range

Low < 5 pg/mL
Normal 5 - 21 pg/mL
High > 21 pg/mL

The normal Free Testosterone range is between 5.0 and 21.0 pg/mL.

High Free Testosterone Levels (Above 21.0 pg/mL)

Causes of High Free Testosterone

High free testosterone may be due to PCOS, anabolic steroid use, or adrenal tumors. Balancing hormone levels through lifestyle adjustments and medical intervention may be necessary.

Health Effects of High Free Testosterone

Excess free testosterone can result in hormonal imbalances, fertility issues, aggression, acne, and cardiovascular disease risk.

Low Free Testosterone Levels (Below 5.0 pg/mL)

Causes of Low Free Testosterone

Low free testosterone is often linked to aging, obesity, insulin resistance, or high SHBG levels. Strength training, weight loss, and optimizing sleep can help improve levels naturally.

Low free testosterone can lead to fatigue, muscle loss, reduced libido, and difficulty maintaining body composition.
