Testosterone is often associated with macho men or aggressive behavior. But testosterone plays a much larger role than the myths linked with it. It’s a hormone found in both males and females, but levels are much higher in males.
In men, testosterone is a hormone produced by the gonads (sex organs). It plays different roles in three life stages:
Fetal development – Testosterone initiates the development of male internal and external reproductive organs.
Puberty – Testosterone causes changes such as an increase in height, body and pubic hair; enlargement of the penis, testes and prostate gland; and an increase in libido.
Adulthood – Testosterone is essential for sperm production, new red blood cells, bone and muscle strength, and a sense of well-being.

Testosterone Levels
Having too little or too much testosterone can have a negative effect on your health. It’s usually the highest in the morning and lowest in the evening. There are signs to look for that can indicate high and low testosterone levels.
High Testosterone
Testosterone levels vary over time and during the day. Some symptoms of high testosterone include:
low sperm count
prostate enlargement with difficulty urinating
acne
weight gain
increased muscle mass
mood swings and irritability
Low Testosterone
Men over age 45 may have a higher frequency of low testosterone levels. Some symptoms include:
reduced body and facial hair
decreased muscle mass
low libido
poor concentration
brittle bones
Testosterone is essential in men for reproductive and overall health. It’s natural for testosterone levels to fluctuate depending on age and overall health. However, if levels are consistently high or low, treatments are available.
Your Primary Care Provider can check your testosterone levels with a blood test and recommend treatments to relieve your symptoms.
