Symptoms of Hormone Deficiencies

Men experience a wide range of symptoms due to hormonal deficiencies, most of which are related to low testosterone levels. Testosterone affects a man’s reproductive function and secondary sexual features such as growth of facial and body hair as well as muscle mass and bone density. From their mid-30s to 40s, male hormone levels tend to decline. By the age of 60 years, about 2 in 10 men will have low testosterone and by the age of 70 to 80 years, about 3 in 10 men will suffer from this condition.

Common symptoms of hormonal deficiencies in men may include:

  • Significant decrease in sexual desire
  • Difficulty achieving and maintaining an erection
  • Decrease in the volume of semen produced during ejaculation
  • Loss of muscle mass
  • Increased body fat with enlargement of breast tissue
  • Thinning of bone with increased susceptibility to fractures
  • Extreme fatigue and tiredness despite getting enough sleep
  • Loss of hair or decreased hair growth on the body and face
  • Mood changes and irritability
  • Anxiety
  • Depression


Unlike women, the slowing down of hormone production is not as abrupt and hence the changes that occur in men are more subtle. The older a man gets, the more likely he will suffer from hormone deficiencies and benefit from bioidentical hormone replacement.
