Current research shows that men who don’t get enough sleep run an increased risk of developing sexual dysfunction. In fact, a new study reveals that sleep is second only to weight gain as the most important factor affecting levels of testosterone, which is the hormone that plays a key role in men’s fertility, sexual function, energy, and mental health. According to the study of nearly 2,300 college-aged men, poor sleep was linked to lower levels of testosterone. This key finding has important implications for men who have fertility issues, but do not want to undergo hormone treatment. Instead, an alteration to their lifestyle that is as simple as getting more sleep may help them elevate their testosterone levels.
P.S. According to the study mentioned above, men who slept less than the recommended seven hours experienced a drop of 5.85 ng/dL of testosterone for every hour of sleep lost.
