Does Polyester Decrease Testosterone? What You Need to Know

Can the Fabric of Your Underwear Affect Testosterone Levels?

While diet, exercise, and lifestyle play the most significant roles in maintaining hormonal balance, some research suggests that the fabric you wear may also influence comfort and body temperature, which can indirectly affect testosterone production. Understanding how different materials interact with your body helps you make more intelligent choices for long-term health.

How Polyester Affects the Body

1. The Connection Between Polyester and Heat Retention

Testosterone production is temperature sensitive. The body naturally keeps the testes cooler than the rest of the body for proper hormone function. Polyester, a synthetic fabric with low breathability, traps heat and moisture against the skin. Wearing breathable moisture-wicking underwear allows air circulation and helps maintain a cooler temperature, reducing excess warmth that could affect hormonal balance.

2. Does Polyester Cause Moisture Buildup?

Polyester has poor moisture absorption, so sweat tends to stay on the skin. This can cause irritation, discomfort, and a damp environment. Choosing underwear made from high-performance fabrics that wick away sweat will keep you dry and cool throughout the day.

Key features to look for

Does polyester decrease testosterone?
There is no conclusive evidence that polyester directly lowers testosterone levels. However, it retains heat, and prolonged warmth in the groin area may influence hormone regulation over time. Switching to breathable, moisture-wicking fabrics helps maintain a temperature balance.
