A small, non-placebo controlled clinical trial testing testosterone patches in men with relapsing-remitting multiple sclerosis offered promising results. Brain atrophy slowed by 67 percent in ten men receiving daily transdermal testosterone treatments for one year. Their cognitive function also increased.
Beyond the obvious caveats associated with non-placebo controlled trials, it should be noted that participants "began the study with relatively low levels of disease activity on MRI." These results will need to be confirmed by controlled trials using a larger pool of patients before this can be offered as a standard treatment for MS.
Women have a similar trial in the works testing estriol, so this is an equal opportunity thing: You take your sex hormone, I'll take mine.
