As a subject matter expert in endocrinology, I can provide you with information on average testosterone levels by age. Testosterone is a hormone that plays a crucial role in the development of male reproductive tissues and secondary sex characteristics. It is also present in females, but in much lower levels. Testosterone levels can vary widely in both men and women, and they are influenced by a variety of factors including age, overall health, and lifestyle.
In men, testosterone levels typically follow a certain pattern throughout life:
1. Fetal Development: High levels are present during fetal development.
2. Adolescence: Levels rise significantly during puberty to initiate the development of secondary sexual characteristics.
3. Young Adulthood (20s-30s): Testosterone levels peak, usually in the late teens to early twenties.
4. Middle Age (40s and beyond): There is a gradual decline in testosterone levels, a process sometimes referred to as "andropause" or "male menopause," although these terms are not medically recognized conditions.
The average testosterone levels in adult men are often cited as being around 300 to 1,000 ng/dL (nanograms per deciliter), with the normal range typically considered to be between 280 to 800 ng/dL. However, it's important to note that what is considered "average" can vary based on the source and the population studied.
For women, testosterone levels are significantly lower, with the normal range being around 15 to 70 ng/dL.
It's important to consult with a healthcare professional for personalized information, as individual levels can differ greatly and what might be normal for one person may not be for another.

In general, the normal range in males is about 270 to 1070 ng/dL with an average level of 679 ng/dL. A normal male testosterone level peaks at about age 20, and then it slowly declines. Testosterone levels above or below the normal range are considered by many to be out of balance.
