Cold therapy gets talked about in men’s fertility for one simple reason: s***m are very temperature-sensitive.
S***m are produced best at around 2 - 4°C below core body temperature, which is why the te**es sit outside the body. Chronic heat exposure (think tight underwear, skins or lycra, laptops, prolonged sitting, cycling, hot baths and saunas) has been linked with lower s***m count, motility, morphology and increased DNA damage (1).
Gentle, short-term cooling may help by reducing excess heat and oxidative stress in the te**es, creating a more supportive environment for s***m development. This matters because s***m take around 2–3 months to mature. What’s happening now affects future s***m quality.
That said, cold therapy isn’t a standalone fix. Meaningful improvements in s***m health come from addressing the bigger picture - reducing heat exposure day to day, supporting the body with nutrition, managing stress, and using therapies like acupuncture to optimise circulation and hormonal signalling.
At Yin, we offer a range of Traditional Chinese Medicine and more modern techniques in our treatments for s***m health - acupuncture, electro acupuncture, low level laser therapy (photobiomodulation - ie no heat) and lifestyle advice as above.
