Testosterone is often referred to as the “male hormone” for good reason. It’s responsible for regulating many important functions in a man’s body, including sexual desire, sperm production, muscle mass, and even mood.
In simple terms, testosterone acts on receptors in the brain, particularly in areas linked to sexual behavior. When testosterone levels are high, these receptors send signals that increase sexual desire and motivation. On the other hand, when testosterone levels decline, the signals weaken, causing a reduction in sexual thoughts, desire, and performance.
Testosterone also helps stimulate the production of dopamine, a neurotransmitter associated with pleasure and reward. Lower testosterone means lower dopamine activity, making it harder for men to feel motivated or interested in sexual activity.
