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.
Almost all of the clinical trials studying TRT have been inconclusive or have not followed patients long-term, so this treatment option is still a bit experimental in practice, and the treatment should not be administered to anyone not deemed an exceptional candidate. Because of the serious nature of TRT, patients with less severe testosterone deficiencies may look into safer, alternative treatment options. Any man currently taking TRT needs to see their doctor regularly for checkups, and should report any medical issues immediately. In addition, prostate screenings are essential.

But I'm not more aggressive—a behavior change often tied to testosterone. That's not surprising to Robert Sapolsky, ., a neuroendocrinologist at Stanford University and a leading researcher on stress and behavior. "It's really not the case that testosterone 'causes' aggressive behavior," he says. "Instead, it makes the brain more sensitive to social cues that trigger aggression. And in support of that, a guy's testosterone level isn't a very good predictor of how likely he is to be aggressive."
