What is the average percentage of water in adult males?

The average percentage of water in adult males is typically around 60%. This percentage can vary based on several factors such as age, body composition, and fitness level. It's important to understand that adult males generally have a higher water content compared to females, primarily due to a greater proportion of lean muscle mass, which contains more water than fat tissue.

The options presented reflect common misconceptions or variations. For instance, while some sources may list figures on the higher end (like 68% or 72%), these can refer to specific sub-populations or conditions, but they do not represent the average in the general adult male population. Similarly, a lower figure like 55% would not accurately portray the typical adult male's body composition since muscle tissue, which is predominant in males, comprises more water. Thus, the most accepted average figure remains closer to 60%.
