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.
If a young man's low testosterone is a problem for a couple trying to get pregnant , gonadotropin injections may be an option in some cases. These are hormones that signal the body to produce more testosterone. This may increase the sperm count. Hedges also describes implantable testosterone pellets, a relatively new form of treatment in which several pellets are placed under the skin of the buttocks, where they release testosterone over the course of about three to four months. Injections and nasal gels may be other options for some men.
