Testosterone is the primary male sex hormone produced mainly in the testicles. It plays a crucial role in male sexual development, muscle mass, bone density, and overall well-being. Both men and women produce testosterone, although men have much higher levels.
Testosterone is essential for many bodily functions:
Testosterone levels are highest during adolescence and early adulthood. After age 30, testosterone naturally declines by about 1% per year. Low testosterone can cause symptoms like:
| Age Range | Avg. Testosterone Level |
|---|---|
| 10-13 | 1.8-7.7 nmol/L |
| 14-17 | 10.4-41.6 nmol/L |
| 18-30 | 10.4-41.6 nmol/L |
| 30-50 | 9.1-37.3 nmol/L |
| 50 | 6.3-26.3 nmol/L |
Normal testosterone levels in adult males range from about 9-38 nmol/L
Several factors can influence testosterone production:
| Factor | Effect |
|---|---|
| Age | Levels decline ~1%/year after 30 |
| Obesity | Lowers testosterone |
| Sleep deprivation | Decreases testosterone production |
| Alcohol abuse | Reduces testosterone levels |
| Estrogen excess | Suppresses testosterone function |
Lifestyle changes like losing weight, exercising regularly, managing stress, and getting enough sleep can help maintain healthy testosterone levels. In some cases, testosterone replacement therapy may be recommended to treat very low testosterone.
See a doctor if you have symptoms of low testosterone that are impacting your quality of life, such as low libido, difficulty with erections, depressed mood, low energy, and unexplained weight gain.
