Testosterone Levels by Age
Testosterone is a hormone that is present in both men and women; although, testosterone levels in men are much higher. In men, levels typically start to decline after age 30 while levels start to decline by age 45 in women. The hormone plays a pivotal role in the human body and in various aspects of adult health.
The Role of Testosterone in the Body
How Testosterone Impacts Physical Health
Testosterone contributes to muscle mass and strength, making it a crucial factor in physical performance and overall muscular development.
Adequate levels support the production of red blood cells, which carry oxygen to muscles and other tissues, thereby enhancing stamina and energy levels.
It helps to maintain strong bones and reduce the risk of osteoporosis, particularly in aging males.
Furthermore, testosterone is integral to fat distribution in the body, aiding in maintaining a healthy weight and preventing obesity-related health issues.
How Testosterone Impacts Mood and Cognition
Proper levels of testosterone can contribute to a balanced mood and sharp mental acuity, making it an essential element for overall well-being.
Symptoms of Low Testosterone

The Importance of Age in Determining Normal Testosterone Levels
In younger men, higher levels are typical, supporting energy, strength, and overall vitality.
However, as men transition into their 30s and 40s, these levels begin a gradual decline, decreasing by about 1% each year.
This decrease doesn't just affect physical health but can also impact mental well-being and quality of life.
By recognizing these changes, men can take proactive steps to manage their hormone health, addressing issues early and adopting lifestyle changes or treatments to maintain balance.
Normal Testosterone Levels by Age Group
There are a lot of different opinions about what's considered normal and low testosterone levels.
The American Urological Association says that adult men with testosterone levels below 300 ng/dL are considered low.
However, according to endocrinologist, Kevin Pantalone, DO, he says levels below 250 ng/dL are considered low.
A study by the University of Michigan in 2018 which tested 1,486 men between the ages of 20-44 observed the following:
In males between 20-24 years of age, the cutoff for low levels was at 409 ng/dL
In males between 25-29 years of age, the cutoff for low levels was at 413 ng/dL
In males between 30-34 years of age, the cutoff for low levels was at 359 ng/dL
In males between 35-39 years of age, the cutoff for low levels was at 352 ng/dL
In males between 40-44 years of age, the cutoff for low levels was at 350 ng/dL
By the time men reach their 50s and beyond, the decline becomes more pronounced, with levels ranging from 200 to 800 ng/dL. This age-related drop can lead to more noticeable symptoms of low testosterone, impacting quality of life.
The Significance of Regular Testing and Monitoring
Tracking your testosterone levels through regular testing is more than just a health precaution—it's a vital step in maintaining overall well-being as you age. Regular monitoring can catch early signs of imbalances, whether they’re drops that may sap your vitality or spikes that could indicate underlying health issues.
Diagnosing low testosterone
A healthcare provider will first conduct a thorough medical history and physical examination to identify potential signs of low testosterone. Blood tests are then performed to measure the levels of testosterone, with multiple samples often needed to confirm consistent low readings due to the hormone's natural fluctuations throughout the day. Additional tests may be carried out to rule out other medical conditions influencing hormone levels, ensuring a comprehensive assessment is conducted before diagnosing low testosterone.
