2BALLZ x FERTILITY
2Ballz Underwear is designed for men who want to optimize their reproductive health. Our innovative, naturally cooling underwear helps regulate testicular temperature—an essential factor in supporting sperm health and improving the chances of conception.
Featuring our BallzCare Pouch™, 2Ballz Underwear delivers a custom-fit experience with its elasticized, air-flow mesh design. Engineered for maximum comfort, this innovative pouch adapts to your body’s natural movement, allowing the scrotum to extend and retract freely while enhancing breathability and heat dissipation through premium mesh fabric.
For men serious about fertility and everyday comfort, 2Ballz Underwear is a game-changer.
Modern Fertility Struggles

- Male fertiltiy is declining by around 3% each year.
- Men are a contributing factor in 50% of infertility cases.
- Increased sedentary lifestyles contribute to higher scrotal/testicular heat.
- Male fertility is significantly influenced by testicular temperature.
- Sub-quality sperm is a leading cause of miscarriages.
Testicular Heat and Fertility

- Scientific studies reveal that testes are, on average, 2°C warmer when seated compared to standing.
- A 1°C increase in testicular heat can reduce fertility by 14%. 2–3°C increase can halt sperm production entirely.
- Traditional brief underwear holds the testes up against the body, allowing absorption of core body heat.
The 2BALLZ Difference

- Features a scientifically designed air-flow mesh pouch.
- Comfortably supports the testes and scrotum, gently holding them away from the body.
- Allows self-regulation of temperature to maintain 2–3°C cooler than core body temperature.
- Helps optimise sperm health and improve male fertility by maintaining the ideal testicular temperature.
