what age do males go through puberty
The third stage of male puberty occurs around age 13 or 14, but frequently as early as 11 or late as 16. Pubic hair begins to grow darker and fuller, and the penis now begins to grow in length. The testicles continue growing, erections become commonplace and the boy gains in height at a rate of over 3 inches (7.6 centimeters) a year.
