Laptop Computers and Sperm Count

Studies have shown that heating the scrotum by just 1? Cocan reduce sperm count and sperm quality, with long-term consequences. Studies have also indicated that males sitting with a laptop on their laps have increased scrotal temperatures. Does a lap pad help reduce the temperature increase? Does sitting with legs apart help? The study investigated all three of these conditions: legs together and a laptop computer on the lap, legs apart and a laptop computer on the lap, and legs together with a lap pad under the laptop computer. Scrotal temperature increase over a60-minute session was measured inCo, and the summary statistics are given in Table 1.
