Ice on testicles and donating blood – the myths sold to men trying to boost their sperm
Every morning Simon steps into a sauna, after which he straps a cold pack to his groin. He says the ice keeps his testicles at an optimal temperature so that a high sperm count can be preserved.
The mainstream benefits are unclear: heat and cold can both influence sperm quality, but there is little evidence that this exact routine improves fertility dramatically. Extensive exercise, adequate sunlight, consumption of filtered water, and cotton underwear are more reliably linked to improved overall health, yet Simon includes them all in his daily agenda.
The rise in men wanting semen analysis is linked to social‑media anxiety about testosterone replacement therapy and environmental toxins. Influencers with millions of followers post daily “fertility hacks” such as ice packs, red‑light therapy and blood donations that claim to reduce microplastics.
Declining birth rates and the fertility “crisis” narrative
Globally birth rates have fallen from nearly five children per woman in 1950 to 2.2 in 2025, creating headlines about a fertility crisis. Some data point toward a real decline in sperm count since the 1970s, though a 2023 meta‑review notes research gaps and unclear impact on births.
Men are therefore tempted to purchase costly supplements and “stacks” featuring HCG or HMG, even though these drugs are only indicated for medical fertility treatment under clinician supervision. Possible side effects include blood clots, breast growth, and long‑term harm if taken without professional guidance.
The danger of DIY fertility stacks
One story follows a bodybuilder who stopped testosterone and steroid use after learning that these suppress sperm production. He sought professional help, avoided unmonitored “stacks,” and now watches his natural testosterone recover, though his sperm‑stimulating hormone remains low.
Experts warn that the vacuum created by influencer claims can bring men toward harmful self‑experimentation. While some lifestyle changes such as quitting smoking, losing weight, and increasing exercise are proven, they remain under‑used in place of risky protocols.
What can men do safely?
The bottom line is that reliable medical advice should outweigh influencer hype. Men wanting to safeguard fertility should consult reproductive endocrinologists, get semen analysis, and focus on evidence‑based lifestyle improvements. Where temperature control is concerned, keeping testicles at a slightly cooler range—rather than exposing them to extreme heat or cold—might be marginally beneficial, but professional guidance is essential.
