Occupational hazard alert: Scrotal hyperthermia and laptop use.
When I saw this title in my weekly Google Scholar alert, I knew I had to share it. Published by members of the Urology Department, SUNY Stony Brook and available for download at ScienceDirect.com, "Protection from scrotal hyperthermia in laptop computer users" should be read by every male and those who love them. From the abstract:
Right and left scrotal temperature and LC and lap pad temperatures were recorded during three separate 60-minute sessions using a working LC in a laptop position: session 1, sitting with closely approximated legs; session 2, sitting with closely approximated legs with a lap pad below the working LC; and session 3, sitting with legs apart at a 70° angle with a lap pad below the working LC.
Scrotal temperature increased significantly regardless of legs position or use of a lap pad. However, it was significantly lower in session 3 (1.41°C ± 0.66°C on the left and 1.47°C ± 0.62°C on the right) than in session 2 (2.18°C ± 0.69°C and 2.06°C ± 0.72°C) or session 1 (2.31°C ± 0.96°C and 2.56°C ± 0.91°C). A scrotal temperature elevation of 1°C was reached at 11 minutes in session 1, 14 minutes in session 2, and 28 minutes in session 3.
Sitting position with closely approximated legs is the major cause of scrotal hyperthermia. Scrotal shielding with a lap pad does not protect from scrotal temperature elevation. Prevention of scrotal hyperthermia in LC users presently is not feasible. However, scrotal hyperthermia may be reduced by a modified sitting position (legs apart) and significantly shorter use of LC.
Uh, I think I'll be blogging from my desktop from now on.
