👉 The gentleman fluid, also known as testosterone, is a key male sex hormone that plays a crucial role in the development of male secondary sexual characteristics, such as increased muscle mass and deepened voice. However, it also influences cognitive functions, libido, and overall well-being in men. Unlike the more commonly discussed estrogen, which is predominant in females, the gentleman fluid in men exists in a lower concentration but still significantly impacts various aspects of male physiology and behavior, contributing to the unique characteristics and capabilities associated with masculinity.
