It’s natural to be concerned about lower testosterone levels. Professional organizations have not set a target range, but 500 ng/dL falls within the AUA’s normal testosterone range of 450 to 600 ng/dL. However, laboratories may report levels down to 264 ng/dL as within the normal range. According to the AUA, low testosterone for adult males who don’t have obesity is below 300 ng/dL. Research suggests that females produce three times more testosterone than estrogen before menopause. Some research also suggests that high levels of prenatal testosterone levels may be linked to autism in children. Contrary to popular perception, testosterone isn’t simply a male hormone.
