- Testosterone levels tend to decline with age, but the rate of decline varies among individuals.
- Factors such as testicular function and pituitary hormone production contribute to age-related changes in testosterone levels.
- [01:04:12](https://youtu.be/SzGb9hbvlZ0?t=3852s) Age-Adjusted Reference Ranges for Testosterone
- Debate surrounds the establishment of age-adjusted reference ranges for testosterone.

- [01:08:00](https://youtu.be/SzGb9hbvlZ0?t=4080s) Determining Low Testosterone Levels
- The FDA's threshold for low testosterone levels has historically been set at 300 ng/dL, although this value lacks empirical evidence.
- Endocrinologists have proposed lower thresholds, such as 264 ng/dL, based on studies of healthy young populations.
