Laptop Computers and Sperm Count Studies have shown that heating the scrotum by just 1°C can reduce sperm count and sperm quality, so men concerned about fertility are cautioned to avoid too much time in the hot tub or sauna. A new study¹ suggests that men also keep their laptop computers off their laps. The study measured scrotal temperature in 29 healthy male volunteers as they sat with legs together and a laptop computer on the lap. Temperature increase in the left scrotum over a 60-minute session is given as 2.31 ± 0.96 and a note tells us that "Temperatures are given as C; values are shown as mean $D." The abbreviation SD stands for standard deviation. (Men who sit with their legs together without a laptop computer do not show an increase in temperature.)

Transcribed Image Text:Laptop Computers and Sperm Count
Studies have shown that heating the scrotum by just 1°C can reduce sperm count and sperm quality, so men concerned about fertility
are cautioned to avoid too much time in the hot tub or sauna. A new study¹ suggests that men also keep their laptop computers off
their laps. The study measured scrotal temperature in 29 healthy male volunteers as they sat with legs together and a laptop
computer on the lap. Temperature increase in the left scrotum over a 60-minute session is given as 2.31 ± 0.96 and a note tells us that
"Temperatures are given as ° C; values are shown as mean D." The abbreviation SD stands for standard deviation. (Men who sit
with their legs together without a laptop computer do not show an increase in temperature.)
