Male fertility is increasingly under scrutiny – not only among couples actively trying to conceive, but also among younger men aiming to improve their health and vitality. And while the causes of infertility can range from hormonal imbalances to varicocele, one approach consistently stands out as safe, natural, and highly beneficial: exercise.

But even when sport acts as an ally, there’s one paradox – overheating of the testicles after intense physical activity can negatively impact spermatogenesis. That’s exactly where BREEZERS by PolarCare come in – specialized underwear that allows breathability and temperature control, even after the most demanding workouts.

Why is exercise good for fertility?

Regular physical activity offers numerous benefits for male reproductive health. Moderate workouts improve circulation, regulate the hormonal profile, and reduce oxidative stress – one of the main enemies of healthy sperm. Additionally, exercise helps maintain a healthy body weight – and it’s well known that obesity negatively affects testosterone levels and sperm quality.

Exercise also contributes to reducing cortisol, the stress hormone, which can disrupt hormonal balance if elevated for long periods. In short – movement activates not only muscles, but the entire hormonal system.

When sport becomes a double-edged sword – the impact of heat on the testicles

While sport is beneficial, intense physical exercise can cause an increase in testicular temperature. Tight sportswear, workouts in hot conditions, and increased circulation during exercise create conditions in which the testicles overheat. And we know that for optimal sperm production, the testicles need to be a few degrees cooler than body temperature.

Prolonged overheating can impair sperm motility, count, and structure, significantly affecting fertility – especially in men already experiencing mild issues such as varicocele or hormonal fluctuations.

BREEZERS by PolarCare – functional underwear for athletes and active men

BREEZERS by PolarCare represent a new generation of underwear designed for men with an active lifestyle who don’t want to compromise their fertility. These boxer briefs combine:

• breathability and thermoregulation

• discreet design and all-day comfort

• functional materials that promote better post-workout ventilation

Unlike standard sports underwear, which often traps heat, BREEZERS allow the testicles to "breathe," helping maintain the healthy microclimate essential for quality spermatogenesis.

After an intense workout, the body needs recovery – so why shouldn’t fertility have its own "recovery tool" too?

Who benefits most from BREEZERS boxer briefs?

• Men who train regularly (gym, running, cycling, HIIT)

• Those planning fatherhood and wanting to proactively support fertility

• Men diagnosed with varicocele or previous poor semen analyses

• Anyone seeking comfort, quality, and purpose in one product

BREEZERS fit perfectly into everyday wear – suitable at home, at work, in the gym, or on a walk, without feeling like you're wearing “special underwear.” This discretion and functionality make them truly unique on the market.

An active lifestyle and smart choices

Exercise is one of the best natural allies of male fertility – but as with everything, balance is key. By incorporating products like BREEZERS by PolarCare into your fitness routine, men gain an extra layer of support – one that may not be visible from the outside, but can make a world of difference inside.

If you’re planning fatherhood or simply want to keep your reproductive health at its best, combining smart training with functional underwear may be exactly what you need.
