Testosterone is a key hormone primarily produced by the testes, ovaries, and adrenal glands. It plays a critical role in maintaining muscle mass, bone density, libido, mood, and overall energy levels in both men and women.
Hormonal imbalances can occur when these organs produce too much or too little testosterone, often influenced by stress, aging, medications, lifestyle factors, or underlying medical conditions. Since testosterone levels also interact with other key hormones such as cortisol, estrogen, and DHEA, maintaining hormonal balance is essential for supporting long-term health and optimal physical function.
