Snowballs: cooling underwear for men


Snowballs: cooling underwear for men

By localized application of cold on the scrotum, Snowballs underwear naturally increases the testosterone level and the male fertility, in a fast and significant way
Increases testosterone levels naturally
Improves masculine fertility
helps recover from surgery and improve comfort


Mother nature has placed human testes in an external pouch to the body (called the scrotum) for a good reason: the efficient production of sperm and testosterone which are optimal at 36°C (97°F), over 1 degree below the body temperature.

The modern lifestyle makes us wear warm clothes and often keeps us in a sitting position, which destroyed this temperature difference and with it our ability to create the optimum testosterone and sperm quantity and quality.

It has been proven that the testicles of men with fertility problems are warmer, on average by 1°C.
This difference may seem insignificant, but it is in fact decisive.
More and more studies show that cold applied to the scrotum allows increased levels of testosterone and improve male fertility naturally, rapidly and significantly.
In line with these studies, Snowballs helps you boost your testosterone and fertility. 

Find here the references of medical studies on the benefits of cooling on male fertility.

Soft and comfortable, the Snowballs shorts can be worn all day long, with or without the SnowWedges gel pockets.

Increases testosterone

Lowering the testicles temperature has been a method used for a long time to increase testosterone naturally.

Russian bodybuilders were already using this approach in the 1980s to gain muscle mass.
The Thrombosis Research Institute in London also published a study in 1993 on the link between cold showers and increased testosterone levels.
More recently, ice baths and cold showers are also a method advocated by Tim Ferris in his book "The Four Hour Body".

SnowBalls is a less "violent" and more convenient method of achieving these results and allows for localized applications over much longer periods of time for greater efficiency.

Natural Testosterone has many beneficial effects on the body :
> Promotes building muscle mass and athletic performance
> Prevents the formation of fat (better fat burning )
> Contributes to bone density
> Boosts libido and improves quality of sex

A low scrotal temperature is essential for testosterone production. For optimal functioning, the temperature of the testicles should be between 31 and 36°C (88 and 97°F).
The layers of clothing we wear, sitting for long periods of time or taking hot showers have a negative impact on the proper production of testosterone.
Sitting for long periods of time can increase the temperature of the scrotum by up to 6°C (43°F)!

Wearing Snowballs underwear will lower the temperature of the testicles and thus increase the natural production of testosterone (endogenous testosterone).

On the other hand, an excess of exogenous testosterone (synthetically produced) can have a negative impact on spermatogenesis. Without the need to produce sperm, the testicles will gradually stop doing their job and start to shrink.

It is therefore essential to favour a natural increase in testosterone and to avoid (unless medically advised, of course) synthetic testosterone.
Refreshing is a simple and inexpensive way to do this, along with other natural methods.

Improves fertility

Male fertility accounts for about 40% of conception difficulties.
But the good news is that 88% are treatable and 75% are due to a problem (quantity and quality) of spermatozoa that can be greatly improved by scrotal cooling.

Three different studies show that 33% of infertile men have scrotal hyperthermia.
Snowballs could therefore be decisive for 13% of couples experiencing difficulties in conceiving, while being useful for more than 95% of them (as definitive sterility is only announced in 3 to 4% of cases).
A selection of scientific sources can be consulted on the Snowballs partner site.

Excess heat in the testicles impedes spermatogenesis , which results in a lower quality sperm, and in smaller quantities.
The use of Snowballs unerwear, by acting directly on testicular cooling, will lead to a better sperm production: studies show up to a doubling of the concentration and motility.
A 3 months use at a rate of 2 hours per day proved to be optimal to significantly increase their chances of conception.

If, after a year of regular carnal knowledge, attempts to conceive remain unsuccessful, this can be considered a fertility disorder.
A consultation with a doctor will be necessary to make a diagnosis and to orientate a treatment according to the case.
It is important not to confuse "infertility" with "sterility". Infertility can indeed be reversible. Infertility corresponds in the strict sense of the term to a definitive and irreversible state for a couple to have a child.

Helps recovering from surgery

Snowballs underwear is also particularly useful after a vasectomy, hydrocelectomy, varicocelectomy, inguinal hernia operation or any other operation in this sensitive area of the male anatomy.
The application of freshness indicated by any surgeon in his post-operative recommendations will act locally for rapid and lasting relief.
You will no longer need to walk around with a bag of frozen peas on your crotch (as is still often recommended for lack of an alternative!).
The Snowballs will keep you cool while allowing you freedom of movement (and peas for dinner!).



Place the "SnowWedges" gel pockets in a freezer for about 1 hour before inserting them in the specific compartment of your Snowballs pants for a cooling effect of about 30 minutes. For best results, we recommend that you wear your Snowballs pants with their gel pockets cooled for about 2 hours a day, at a time of your choice.

The Snowballs set includes 2 pants and 3 gel packs.
You can therefore alternate wedges, one being in the freezer and the other one being in the compartment of your Snowballs pants.
When the gel pocket gets saturated with heat just replace it by the one waiting in the freezer.

Afraid of being cold?!
The idea of placing an ice pack between your thighs can make you feel cold...
Don't worry, contrary to what you might think, cooling your genitals is a very pleasant sensation.
Indeed, don't confuse internal temperature with the sensation of hot and cold.

For example, a person who has a temperature is very cold and may even shiver.
A person who is cold necessarily has a too high internal temperature.
Lowering the internal temperature contributes to less chilliness...

Très pratique posted the 03/05/2023 by Adrien
Très simple d'utilisation et très confortable, Il pourrait cependant avoir des kits avec autant de gels mais plus de caleçons

Satisfait posted the 29/03/2023 by Sammy
Très agréable à porter. A pour l'instant l'effet voulu de soulager des gênes lié à une posture assise trop longue et à une varicocèle. Je reprocherai toute fois la difficulté à trouver des caleçon avec la poche sans les glaçons, deux c'est un peu juste.

Super posted the 09/09/2022 by Steven
Produit super très pratique et fait bien ce pourquoi il est fait, seul bémol les poches qui reste bien froide que 10 minutes une fois mise, mais bon on n'y peut rien.
