Clinical research still hasn’t determined a hard threshold level for when symptoms of low T begin appearing . Some recent research suggests that symptoms of low T might begin appearing in men when their total testosterone level dips below 320 ng/dl . According to anecdotal evidence from the owner of Peak Testosterone, many men start noticing low T symptoms when their total testosterone dips into the 400s . Of course, it’s anecdotal, so take it for what it’s worth, but it’s probably a good idea to stay above 500 ng/dl if you don’t want to experience symptoms of low T.
A survey of 28,000 users found that many Italian males started an "excessive consumption" of porn sites as early as 14 years old. After daily use in their early to mid-20s, they become inured to "even the most violent" images. The effects of developing their sexuality largely divorced from real-life relationships are gradual and devastating. "It starts with lower reactions to porn sites, then there is a general drop in libido and in the end it becomes impossible to get an erection," Carlo Foresta, head of the Italian Society of Andrology and Sexual Medicine (SIAMS), told reporters. However, the condition is not irreversible and a proper recovery is possible within just a few short months.
