Males and females are born with testosterone. Males start generating higher amounts of testosterone during puberty, which is when their voices begin to deepen and they start experiencing changes in muscle mass, body hair growth, and sex drive.
- Between the ages of six months and nine years, males and females each have less than between 7 to 20 nanograms per deciliter (ng/dL) of testosterone
- Between the ages of 10 and 11 years, males have less than seven to 130 ng/dL and females have less than seven to 44 ng/dL
- Between the ages of 12 and 16, females have less than 75 ng/dl
- Between the ages of 12 and 13, males have less than 7 to 800 ng/dl and less than 7 to 1,200 ng/dL at the age of 14
- Between the ages of 15 and 16, males have between 100 to 1,200 ng/dL of testosterone
Between the ages of 17 and 18, males have between 300 to 1,200 ng/dL of testosterone, while females have between 20 to 75 ng/dL of testosterone.
Normal testosterone levels in males aged 19 years and older are between 240 to 950 ng/dL, while normal testosterone levels in females aged 19 years and older are between 8 to 60 ng/dL.
What is the Normal Testosterone Level for a 50-Year-Old Man?
In men, testosterone levels normally start to decline after the age of 30. Average testosterone levels for men between the ages of 40 and 49 are 252 to 916 ng/dL. Between the ages of 50 and 59, testosterone levels decrease even more to between 215 to 878 ng/dL.
Men who have low testosterone levels will usually experience a range of symptoms that affect their sex drive and overall health and well-being. Depression, fatigue, and weight gain are just some issues men can experience when their testosterone levels start to dip below average.
