In a 2011 study, researchers determined that just a week of getting 5 hours per night of sleep can drop Testosterone levels 10-15%. In just one week!

“After 1 week of 8-hour bedtimes (from 11 PM to 7 AM) at home, the participants spent 11 days in the laboratory for 3 nights of 10-hour bedtimes (from 10 PM to 8 AM; rested condition) followed by 8 nights of 5-hour bedtimes (from 12:30 AM to 5:30 AM; sleep restriction).”

While I work with a lot of guys who seek me out for help with things like low sex drive, and fatigue, and weight gain, you’d be surprised that a lot of women are looking for help too.

While the fundamental approach is the same- reducing the impact of the various types of stress that screw up the balance between stress hormone and sex hormones, the specific changes can be a little different.
