Methadone treatment can cause testosterone levels to plummet, finds Mcmaster study

Some men who participated in the study had testosterone levels that were 75 per cent lower than men who weren’t using methadone. Addiction specialists say they knew of the effect but did not realize how drastic it could be. A recommendation of the researchers is that when a man is taking methadone to control opioid addiction, he should ask for testosterone level monitoring and possible replacement therapy.
