Snowballs™ is a scientifically backed, patent-pending cooling underwear that was conceived as a natural fertility aid for men… as well as for all men who wish to benefit from practicing the cooling arts.

Studies have shown that lowering scrotal temperature by even one degree Celsius can increase sperm count and quality, and our convenient, comfortable, organic cotton boxer-briefs are guaranteed to make you cooler. Snowballs™ are a perfect icing solution for:

• male infertility
• vasectomies
• varicoceles
• hydroceles
• spermatoceles
• epididymitis
• athletic injuries
• testosterone enhancement

Each order of Snowballs™ includes two pair of our special underwear, designed to be worn all day, and three of our unique SnowWedges™, so there’s always one ready to keep you cool. After inserting a SnowWedge™ into the pouch of your Snowballs™, you’ll stay comfortably cool for about 30 minutes. Snowballs™ can be gently machine washed like any other pair of quality organic underwear. SnowWedges™ can be washed with soap and water and freeze for use in less than an hour.

“So here’s what we’re doing,” we would say at parties. “We’re researching cooling devices and the male…anatomy…in order to create comfortable underwear that will chill your balls.”

This was a conversation starter, to put it mildly. Several months later, when an unsuspecting lunch guest caught us in the kitchen holding freezer bags to the fronts of our pants, we were already convinced that we were onto something big. The lunch guest had her doubts.

Male infertility accounts for roughly 40% of all infertility, but it’s still tough to sound cool when talking about it. That’s why we loved the name we had dreamed up for our still-imaginary product: Snowballs! Some thought it was insensitive, or inappropriate, but for us it was just a punch line for a story we were dying to tell. You see, we had both been through the “fertility factory” with our wives, losing our money and our minds until we began to look more closely at the actual causes of infertility…and became obsessed by heat.

It was T and his wife who really provided the breakthrough. It had been a painful year. There had been a silent miscarriage after two years of trying, and the best doctor that money could buy had said that their chances were now zero. Think about adoption. Think about overpopulation.

They ignored his advice and saw another doctor, and then another, until finally one gynaecologist took the time to sit down with them and listen carefully. Almost immediately, he had a new plan. First, T should begin icing his balls. Huh? And then he should have himself tested for a varicocele. Again, huh?

A Brief History of Scrotal Cooling

Since the mid-Sixties, scientists have been aware that scrotal cooling could improve male fertility, but no controlled tests were done until the mid-Eighties, when the advantages of cooling were first clinically shown. Now, with an increasing number of studies confirming its effectiveness, some of the world’s best fertility specialists are beginning to prescribe icing.
We know now that the testes of men with fertility problems tend to be naturally warmer by an average of over one degree Celsius, which is significant in this delicate science. We also know that if we can lower scrotal temperature on a consistent basis, fertility will improve. (See our FAQ section for more details on the science).

Control

We found that the most frustrating aspect of playing fertility roulette was the loss of control. There was something wrong, but nobody was sure exactly what. Doctors were looking at us under microscopes and seeing things we would never see (and these were wonderful, competent doctors). It didn’t feel as if we were in control.

Then, when a last doctor mentioned scrotal cooling and varicoceles, we began to do research on something that actually made intuitive sense (see our FAQ section for some of what we learned). That’s when we began to get excited. We were no longer under the microscope all the time. We were men, and we fixed things.
And didn’t it make sense that if higher temperatures damaged sperm, then we could rig up a way to cool our…balls? We were taking the vitamin supplements and limiting the booze, and surely that was all helping, but didn’t it make sense to directly treat the part of the body with the problem?
Of course it made sense. We would never replace our doctors, but science was on our side too, and most importantly: we were back in control.

The Research

More and more, studies are showing the effectiveness of scrotal cooling. See our FAQ section for a more in-depth look at the science, but here’s a brief overview of a few studies:

• In a study by Mulcahy (1984), fifty men with reduced sperm motility applied ice packs to the scrotum at night. After treatment, both sperm density and sperm motility had at least doubled in 65 percent of the patients. Mulcahy JJ, ‘Scrotal hypothermia and the infertile man.’ Journal of Urology, 132/3 (1984), pp. 469-70
• Jung et al (2005) found a significant increase in both sperm concentration and total sperm count as a result of nocturnal scrotal cooling. For twelve weeks, twenty infertile men used a cooling technique every night, and significant change had taken place by eight weeks. Jung, A., Schill, W. -B., Schuppe, H. -C., ‘Improvement of semen quality by nocturnal scrotal cooling in oligozoospermic men with a history of testicular maldescent.’ International Journal of Andrology, vol. 28/2 (2005), pp. 93-98
• Zorgniotti and Sealfon (1988) measured scrotal temperatures in 300 sub fertile men and 30 control men. They found a statistically significant difference in temperature between the two groups (1.35 degrees Celsius), suggesting that ‘small intrinsic temperature increases may interfere with the ability of the testis to accommodate to environmental temperature stresses and so lead to abnormal semen and sub fertility.’ Zorgniotti, A. W., Sealfon, A. I., ‘Measurement of intrascrotal temperature in normal and subfertile men.’ Journals of Reproduction and Fertility, vol. 82 (1988), pp. 563-66
• Laven et al (1988) studied 56 men from infertile couples. The men were categorized into two groups named ‘cool workers/sleepers’ and ‘warm workers/sleepers’ according to whether or not there was evidence of extra scrotal insulation in their lifestyles. They found a greater number of good moving sperm in the ‘cool workers/sleepers’ group, both per ejaculation and per ml. Laven, J. S., Haverkorn, M. J., Bots, R.S., ‘Influence of occupation and living habits on semen quality in men (scrotal insulation and semen quality).’ Eur. J Obstet Gynecol Reprod Biol., vol. 29/2 (1988), pp. 137-41

A Miracle Cure?

We believe in miracles, but don’t count on Snowballs to work “miracles”. They should increase both sperm quality and quantity, and they should give you a better chance to conceive at minimal cost, but fertility science is complex, and you’ll also want to consult with a urologist (for varicoceles), as well as your fertility specialist. Snowballs may end up being just a supplemental treatment for you. It can’t hurt, and it will likely help. At the same time, do your own research (see our FAQ section for more) and think for yourself. IUI and IVF didn’t work for us, and we met several world-class doctors before one suggested that scrotal temperature might be the problem. People said we were crazy to ice ourselves. We looked desperate to our friends. But in our case, cooling worked, and although every case is different, it is our fervent hope that it works for you too.

Congratulations. You just got 1% cooler.

Designing Snowballs

Having discovered that there were simple, organic solutions to male infertility, it was important to us that Snowballs™ be designed as close to nature as possible. We wanted our customers to understand our patent-pending product from the inside out, because so much of our experiences with infertility had been such a mystery. So here’s everything:

• Organic Cotton – we insisted that the underwear be soft, comfortable, and 100% natural
• Freezable Gel (Carboxymethyl Cellulose Sodium)– we insisted that it stay cold for as long as possible, that it be shaped ergonomically, and that it be entirely non-toxic. The formula we use is a modified version of natural cellulose. It has no taste or smell, is entirely non-flammable, and if you were forced to swallow it on an inadvisable dare, your wife might kill you, but our gel won’t affect you in the slightest.
• Biodegradable Plastic Casing and Packaging – we insisted that it be durable for years but nonexistent for our great-grandkids

The Package

Each order of Snowballs™ includes: two pair of our specially designed underwear, so that you can always have one on hand to wear anywhere, at home or at the office; and three of our unique SnowWedges™, so that there’s always one ready to help you cool down.

Daddy Cool

After inserting a SnowWedge™ into your Snowballs, it should keep you cool for at least 30 minutes, and although testicle icing is never high on anybody’s list of things to do, we’ve designed these wedges to give you the beneficial cooling you need without being painful.

How much should you cool per day? A least a couple of hours is ideal, and we strongly advise you not to ice for more than an hour at a time. Keep the underwear on if you like – we’ve designed it to be worn all day long (although you should also see our FAQ section for more tips about underwear) – but you should have a SnowWedge™ inserted at just certain times during the day: after a workout, getting under the covers at night, or simply when it’s convenient for you.

Our cotton underwear can be gently machine washed like any other pair of quality organic underwear. SnowWedges™ can be washed with soap and water and will freeze completely (but stay flexible) in less than an hour.

Congratulations. You just got 1% cooler.

How long does it take the body to create a spermatozoa?

About 74 days, or approximately 10 weeks. This process is continually beginning anew, however, so any “organic” treatment for male infertility will ideally be done over a period of several months.

What effect can heat have on sperm quality?

Heat can kill sperm, but just as importantly, it creates conditions that complicate your body’s ability to efficiently produce sperm, resulting in lesser quality (“sperm motility”) and lesser quantity (“sperm count”). A consistent scrotal temperature increase of even just one degree Celsius will adversely affect your sperm production.

Why does cooling work?

Studies have shown that occasionally reducing the temperature of the scrotal area by just 2-5 degrees Celsius can reverse male infertility. The enzymes responsible for testosterone and sperm production work most effectively at a certain optimal temperature, and even a one-degree increase in temperature takes you out of the optimal zone. Keep yourself cool, and your body will be able to do its job most efficiently.

How are Snowballs SnowWedges™ designed to maximize these benefits?

Our patent-pending SnowWedges™ have undergone extensive testing with consulting doctors. They are designed with a central hinge that cleverly molds the SnowWedge™ around your body to reach maximum surface area and maximum cooling. Unlike normal icepacks, they won’t get you wet, and you won’t have to sit there holding ice for hours. Admit it: even if you understand that testicular cooling is good for you, and even if you want a child more than anything, you’re not likely to keep up an unpleasant, messy, and time-consuming routine for long. With Snowballs™ you can keep moving, keep working, and keep playing, without wasting time thinking about a problem that you’re undoubtedly devoting enough mental and physical energy to already.

Can I see improvements with just a couple of hours of cooling a day?

Yes. Your body is always producing sperm, and the more often you create the optimal conditions within yourself for that production, the better. The goal is to decrease your daily average scrotal temperature.

When should I cool?

Snowballs™ have been designed to make cooling convenient: anytime, anyplace. But give some thought to when your body temperature is the highest – after a workout, under the bed covers, coming out of the shower – and try to establish a routine that keeps you cool at the times you know you’re hottest. This will decrease your daily average scrotal temperature as effectively as possible.

How soon can Snowballs™ positively affect spermatozoa?

Studies of men who cooled their testicles nightly showed a significant increase in sperm count after just eight weeks, and a further increase after twelve weeks. Given the time it takes to produce sperm; three months of treatment is recommended to see a marked improvement.

What other measures can I take to reduce scrotal temperature?

Heat is your enemy. We advise you to wear looser pants and underwear (or no underwear at all), avoid saunas, baths, and excessively hot showers, put your laptop anyplace other than your lap (in your lap, those laptops have been shown to increase your temperature by 2.8 degrees, which is more than enough to do some damage), occasionally wash your scrotum in cool water, and eventually, in consultation with your doctor, consider varicocele embolization or surgery.

What are varicoceles, and what is the difference between varicocele embolization and surgery?

Varicoceles, which bring additional blood and heat to the scrotum, are the cause of male infertility in 40% of cases.

Incredibly, the cause of infertility in roughly 40% of infertile males is a varicocele. A varicocele is an enlarged vein in the scrotum that causes abnormalities in the temperature regulation of the testis. You’ve heard of varicose veins in legs. Well they can also develop in the scrotum, and they’re more common than people suspect. 15-20% of all men have a varicocele, and it’s logical that an enlarged vein carries more blood and brings more heat. In addition, because the vein is enlarged, the valve that prevents blood from settling in the vein may not close completely, keeping excessive blood in the scrotum, which means additional heat. Again, heat is your enemy.

To treat a varicocele, the options are surgery or varicocele embolization. Surgery (a varicocelectomy) is minimally invasive and has a high success rate (with 97% of men regaining normal blood flow and sperm production), but it can be costly (roughly $4,000). Varicocele embolization is a process as effective as surgery, but requiring no incision to the scrotum and no general anaesthetic. It’s painless and patients generally return to work the next day. The cost, however, is usually as high as surgery.

Snowballs™ can help minimize the effects of a varicocele, but it’s also worth asking a doctor specialized in male fertility about additional solutions. Procedures for treating varicoceles are relatively new, so you may meet with some scepticism, but once we began to do a bit of research, we were blown away by the implications.

What other lifestyle changes can I make to increase my chances of conceiving?

• Stop smoking. Studies have shown that smoking damages sperm, but fortunately the damage can be reversed if you stop.
• Drink less, and avoid hard alcohol. Excessive alcohol consumption has also been shown to damage sperm. Incidentally, your partner in pregnancy really shouldn’t be drinking either, so find a new drink together.
• Avoid heavy cell phone use. Research on this is still developing, but at least one study has shown that men who use a cell phone for more than 4 hours a day have lower average sperm counts and sperm quality.
• Eat as healthily and organically as you can. There has been some interesting research on pesticides found on produce and on hormones added to meat and dairy products. These additives can have a significant effect on a man’s hormonal balance. Interestingly, many pesticides mimic the hormone estrogen, which lowers sperm count and semen production. And fiber, which is found in lots of grains and vegetables, can help the body rid itself of unnecessary estrogens.
• Try a vitamin supplement for 3-6 months. There are some supplements for male fertility on the market, but look for these vitamins and herbs.

1. Maca: increases libido and healthy sperm
2. Tribulus: increases testosterone and luteinizing hormone, which stimulates the testes to secrete testosterone
3. Ginseng: increases sperm count and sperm motility
4. Zinc: important for increasing testosterone levels
5. Folic acid: men with low levels of folate have a higher risk of producing sperm with too little or too many chromosomes, which in turn can lead to birth defects and miscarriage
6. Vitamin C: can protect sperm from oxidative damage (especially important for smokers)
7. B12: may improve sperm count and sperm motility
8. L-carnitine: an amino acid, L-carnitine is essential for sperm formation, maturation, and quality maintenance
9. Antioxidants: antioxidants protect the sperm from free radicals, which can damage the sperm’s health, leading to higher proportions of birth defects and miscarriages

• Work out at least 3-4 times a week (and avoid cycling).
• Sound mind in sound body. Live well, think positive thoughts, be healthy for your own sake first.

Use Snowballs™ daily and make these lifestyle changes, and you’ll almost certainly see an increase in sperm count and quality, giving yourself the best shot for conceiving.

Congratulations. You just got 1% cooler.
