As individual’s level of testosterone depends on their unique bodily characteristics. In some cases, a male’s testosterone levels begin to decline after they turn 18. Though this decrease can certainly happen, it generally doesn’t occur all at once. Normal testosterone decline is slow, typically taking place over the course of decades.
After reaching 30, male testosterone levels decline by roughly 1% each year. This can be alarming for individuals who suffer from low testosterone levels, especially if they didn’t realize they suffered from low levels of testosterone while they’re young. Testing your testosterone levels as you age is an essential part of preventing the physical and emotional backlash associated with low hormone levels.
In women, testosterone levels decline between ages 55 and 65. However, the effects of testosterone levels dropping aren’t as difficult to cope with in women. In fact, many women still possess enough of the hormone to combat some of the impacts of menopause.
Though testosterone levels naturally decline with age, the process can be sped up by taking part in unhealthy lifestyle activities. Eating certain specific foods (ex. Soy-based products), eating unhealthily, and neglecting to exercise all can contribute to a decrease in testosterone.
Another way to look at it is that an unhealthy lifestyle prevents your hormone levels from remaining at their fullest potential dictated by your body’s chemistry. Instead, they travel toward your body’s lower natural range of testosterone. Unless you already have a naturally low level of testosterone, this typically isn’t enough to encourage horrible side effects.
