During which ages does puberty usually occur in boys?

Puberty in boys typically begins between the ages of 11 to 15 years old. This range reflects the average onset of biological changes associated with puberty, which include increased testosterone production, growth spurts, and the development of secondary sexual characteristics such as deeper voices and facial hair. The onset of puberty can vary from individual to individual, but the majority will start experiencing these changes within this age frame.

The other options suggest narrower or wider ranges that do not reflect the most common age range observed for boys entering puberty. While there may be some variation, the 11 to 15-year-old range captures the general timeline observed in Pubertal development.
