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.
“The trials’ results indicate that, for older men with low sexual function, testosterone treatment can contribute to improved function,” said Evan Hadley, ., director of NIA’s Division of Geriatrics and Clinical Gerontology. “In contrast, though, the results don’t indicate that testosterone treatment for older men with low walking ability or vitality will improve these conditions to a great extent. Additional trial arms tested effects on other aging-related outcomes, and we are looking forward to their results to help provide further insights into testosterone use in older men.” Older men should consult their physicians if considering a testosterone treatment, Hadley emphasized.
