So, 2018 was a big year for inventions. Self-driving luggage was brought to our attention, China built an artificial sun because why the hell not? And, of course, we were introduced to the 'Autoblow AI' - the world's first oral sex simulator...
But 2019 ain't doing too bad itself, and we're only on the fifth day. It's getting off with an absolute bang, and a cold one at that, because a team of medical scientists from Poland have come up with a testicle cooler.
They had to wait for Christmas to pass, didn't they.
All joking aside, the device is a non-invasive alternative to male infertility and could help with improving the wearer's sperm count.
The downside to this device is that it will set you back around £240 ($305) and it should be worn for 12-16 hours a day. So, you essentially have to wear what looks like a strap-on (but without the, erm, crucial bit) for the entire day?

You could wear it through the night but if you want to reach the optimum benefits, you're better sticking it on after a morning shower and taking it off after tea (by which we mean the last meal of the day, but that's an argument for another time).
Oh and by the looks of the video, it will also record your steps, heart rate and calorie intake - who needs a Fitbit?!
As well as temperature, the CoolMen records many other things. Credit: CoolMen
According to Business Insider, to produce sperm, the testicles need to be 1-2 Degrees Celsius (°C) lower than your body temperature.
Male infertility can be caused by many different factors like tight clothes, regular use of saunas, sitting at a computer or driving the car for hours on end. Other contributing factors are unhealthy lifestyles including smoking, bad diets and obesity.
Cooltec, the company behind the device, claims that disorders in sperm production are 'most commonly associated with elevated testicular temperatures'.

The website explanation continues: "Elevated temperatures result in the death of cells from which spermatozoa are formed and further stages of the spermatogenesis process.
"Because of this, the quality of the semen from superheated testicles decreases."
The wearer of the CoolMen can connect his smartphone into it to allow real-time temperature monitoring.
And, just in case you needed it selling any more - did I mention you can charge it up using the USB port in the car... winning.
