Why are the testicles outside the body? And what that tells us about the cold
It's a question we've all asked ourselves at least once (without really daring to ask it): why are the testicles outside the body , while all the other vital organs are nice and warm inside? 🤔
Spoiler alert: the answer is scientific, thermal… and fascinating ! By understanding it, we realize to what extent cold plays a central role in our bodily balance, our fertility and our intimate well-being , for all genders. And in passing, we understand even better the interest of perineal cryotherapy , like that offered by Maholi.
🌡️ A question of temperature (and sperm survival)
The human body is a well-calibrated machine
The human body operates at an average internal temperature of 37°C . But sperm are much more fragile: they need to evolve at around 34°C , or 2 to 4 degrees cooler. 🔬
This is why the testicles are located in the scrotum, outside the body , a bit like a mini mobile cold room. This helps maintain an ideal temperature for sperm production (spermatogenesis) .
Too much heat = decreased fertility
When the temperature of the testicles rises (wearing tight clothing, hot baths, excessive heat, etc.), the quality and quantity of sperm decreases . This is a very serious subject for men who want to conceive a child , and a prevention angle that is still little known.
🔎 A study by Ben-Gurion University showed that male fertility increases in winter : sperm are more numerous, more mobile, and better formed.
What this teaches us about the cold and our intimate well-being
Cold is not an enemy… it’s a regulator
Contrary to popular belief, the cold does not “block” the body . On the contrary: it helps it regulate itself naturally . This is true for the testicles, but also for the pelvic area in women.
At Maholi, we use this logic to create our products: cold packs to apply to the perineum , inspired by the ancestral derivative bath . The goal? To help the body find an optimal temperature, reduce swelling, soothe and boost circulation.

Perineal cryotherapy: “strategic cooling”
The perineum is a richly vascularized area , ultra-connected to the digestive, nervous and hormonal systems. By cooling it slightly with a perineal ice pack , we:
- stimulates blood circulation
- soothes pelvic or digestive pain
- reduces chronic inflammation
- improves overall vitality
And yes: what we do for male well-being also applies, differently but logically, to female well-being.
What Testicles Can Teach Us About… Ourselves
Our body knows when it needs freshness
Nature does nothing by chance: if the testicles came out of the “warm center” of the body, it is to protect a vital function: reproduction . Cold, in the right doses, protects, regulates and optimizes .
This is also what our users feel: many report a deep, sometimes surprising, relief when using Maholi bags:
“ I always prefer natural when it comes to taking care of myself. This discovery has helped me so much! It's easy to use and full of benefits. I feel better overall and that's after just a few days of use. I recommend it 1000%😄” – Emilie, Maholi customer.

💡 Cold, an unsung ally of fertility… and pleasure?
Circulation = vitality (and libido!)
When the pelvic area is engorged, tense or inflamed, blood circulation slows down , which can impact sexual desire, the quality of erections or intimate sensitivity. Cold applied gently:
- decongests tissues
- improves oxygenation
- promotes clearer sensations
- and therefore… can improve libido ! 😏
Freshness also stimulates the nervous system
A cooling effect (like Holi) activates the parasympathetic system, that is, the brain's "rest & relax" mode . And in a relaxed body... sensuality has more room. 💕

Conclusion :
Nature placed the testicles on the outside because cold is essential to our intimate and vital balance . This simple biology lesson reminds us that sometimes comfort doesn't come from warmth... but from a good dose of coolness.
Maholi is part of this logic: reconciling our body with the cold , by making it soft, safe, accessible and natural.
