Testosterone is the primary male sex hormone. In males, it is responsible for the development of the testicles and prostate as well as other characteristics such as muscle mass, bone density, facial hair, sex drive, and sexual function to name a few.

Testosterone Levels by Age

levels of testosterone


With age a mans natural testosterone production begins to taper off. As early as 20 years old a mans natural production begins to slow and men in their mid 30’s will notice the effects of low testosterone. Between the ages of 40-70 is when men notice a significant reduction in their level of the hormone. The reason for this is multifactorial and it can be summed up by one of two things happening,

Hypogonadism which is a condition where the body does not produce enough testosterone or Andropause which is sometimes referred to as ’male menopause’ and it is a much slower, more gradual decline in testicular function and testosterone production over time.

However, both of these conditions will exhibit the same symptoms in men such as

  • Low sex drive
  • Loss of morning wood
  • Stubborn belly fat
  • Lack of lean muscle
  • Depression
  • Brain fog
  • Fatigue
  • Mood swings
  • High cholesterol
  • High blood pressure
  • Arthritis
  • Osteoporosis
andropause symptoms


Nearly 1 in 3 men suffer from low testosterone and by 2025 it is estimated that a staggering 6.5 million men in America will suffer from low testosterone.

Low testosterone is one of the most undiagnosed and untreated conditions today.
