A Cooling device for testicles has been invented by scientists in a bid to boost men's fertility.
The 'CoolMen' gadget is attached to a belt and should be worn for 12-16 hours a day for up to a month to boost men's sperm count, its manufacturers say.
Testicles have to be one to two degrees cooler than a man's body temperature for optimum sperm production, but tight clothes, saunas and laptops can heat them up.
Costing around £240 ($304), the CoolMen is connected to the wearer's smartphone to allow real-time temperature monitoring and is currently undergoing medical testing.
Polish company Cooltec has invented the device – which cups the testicles in a chilled pouch – in a bid to help men conceive, it is reported.
Recent studies show sperm counts around the world are plummeting – men living in Western countries are thought to have nearly 60 per cent less than 40 years ago.
Floundering fertility rates are thought to be down to unhealthy modern lifestyles which involve smoking, bad diets, obesity, exposure to plastics and inactivity.
'Disorders in sperm production are most commonly associated with elevated testicular temperatures,' Cooltec claims on its website.
'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 firm claims up to 50 per cent of infertility cases among couples are down to poor sperm quality, and cooling the testicles can increase sperm counts in weeks.
Developers also say the device could treat varioceles, a type of varicose vein inside the scrotum which can cause infertility.
It should be worn for between 12 and 16 hours a day for three to four weeks, they say, while it chills the testicles and collects temperature data over time.
This data could be used by doctors to find possible reasons for a man's difficulty conceiving, and point to other suitable fertility treatments.
