Which of the following statements is true about water content in men and women?

The correct answer is that men typically have higher water content than women. This difference in body water composition between the sexes is primarily due to variations in body composition. Generally, men tend to have a higher percentage of muscle mass compared to women, and muscle tissue contains more water than fat tissue. As a result, men usually have a greater overall water volume in their bodies.

In terms of percentages, men may have around 60-70% of their body weight as water, while women generally have around 50-60%. This physiological distinction is significant, especially in contexts related to hydration, physical health, and how the body processes substances, including alcohol. Understanding these differences is crucial, particularly in fields such as medicine and law enforcement, where body composition can affect sobriety testing results.
