What Are Free Testosterone Levels Ranges

Free Testosterone Levels

Free testosterone levels for this hormone in a male should fall between a certain range in order for a man to feel his best. Here is a simple outline of what free testosterone level ranges should be according to the experts. Ranges will vary from clinic to clinic, but here are numbers from the Mayo Clinic:

  • Testosterone levels in men from 30 to 40:

30 – 35 years: 1.51 – 18.57 ng/dL

35 – 40 years: 1.39 – 17.69 ng/dL

  • Testosterone levels in men from 40 to 50:

40 – 45 years: 1.26 – 16.81 ng/dL

45 – 50 years: 1.14 – 15.93 ng/dL

  • Testosterone levels in men from 50 to 60:

50 – 55 years: 1.02 – 15.05 ng/dL

55 – 60 years: 0.89 – 14.17 ng/dL

  • Testosterone levels in men from 60 to 70:

60 – 65 years: 0.77 – 13.30 ng/dL

65 – 70 years: 0.64 – 12.42 ng/dL

What is free testosterone? This is the testosterone in the male body that is not bound to sex hormone binding globulin (SHBG) in the bloodstream. Free testosterone levels will decline faster than total testosterone levels. It is important to keep them both balanced in order to avoid feeling negative symptoms.

Free testosterone will decrease at a rate of approximately 50 percent from age 25 to age 75. That is faster than the decline of total testosterone, which drops at a rate of 30 percent from age 25 to age 75.

Keeping levels of testosterone balanced in the body will help to avoid the following symptoms:

Low energy Foggy feeling
Fatigue Difficulty with concentration and focus
Loss of muscle Forgetfulness
Weight gain Depression
Low stamina Anxiety
Low endurance Irritability
Loss of bone mineral density Agitation
Loss of sexual stamina Mood swings
Poor immune system Overall emotional instability
Difficulty healing from injury Erectile dysfunction (ED)
Slow recovery time after working out Low sperm count
Poor sleeping patterns Weak sperm potency
Balding Infertility
Thinning hair Lack of sexual libido
Wrinkling skin High cholesterol levels
Loss of memory Risk for heart attack or stroke

Many more issues can occur when free testosterone levels dip, but testosterone replacement therapy (TRT) can help and stop these problems.
