Does Polyester Underwear Affect Testosterone? A Scientific Look

Can Polyester Underwear Impact Testosterone?

Many men focus on optimizing their health, fitness, and hormone levels. But could something as simple as underwear fabric affect testosterone? Some research suggests that synthetic materials like polyester may play a role in hormonal balance, leading to concerns about long-term use.

The Science Behind Polyester and Hormones

Polyester is a widely used fabric due to its durability and affordability, but studies indicate it may have unintended effects on reproductive health.

Key concerns include:

Heat retention – Polyester traps heat, which may raise scrotal temperature and affect sperm production and testosterone levels.
Moisture buildup – Unlike breathable fabrics, polyester can retain sweat, creating a humid environment that may not be ideal for reproductive health.
Electrostatic effects – Some studies suggest that prolonged exposure to synthetic fabrics can alter the body's natural electrical field, potentially influencing hormonal regulation.

What Makes the Best Underwear for Hormone Health?

Men who prioritize comfort and overall well-being should look for underwear that supports breathability, moisture control, and temperature regulation.

Key features of hormone-friendly underwear:

Best breathable underwear for men – Improves airflow and minimizes heat buildup.

Luxury men’s underwear that lasts – Premium materials that maintain softness and durability.
