What is a key feature of Tanner Stage II in male adolescents?

1. The penis is growing more in length than width

2. The testicles become larger with darker scrotal skin

3. Petuitary gland activity is at a peak

4. The pubic hair is coarse and curly

The correct answer is: The testicles become larger with darker scrotal skin

In Tanner Stage II of male adolescents, a key feature is that the testicles become larger along with the development of darker scrotal skin. This stage marks the beginning of sexual maturation, where physical changes are first noticeable. Typically, the onset of stage II reflects the increase in testicular volume, which is a primary indicator of advancing puberty in males. As the testicles grow, the scrotum also undergoes changes, including darkening of the skin, which signifies emerging sexual maturity. While other features, such as penis growth and pubic hair development, are present as well, the significant and distinctive change in the size and appearance of the testicles and scrotum is characteristic of this stage. This establishes a clear marker for assessing sexual maturation progress in adolescent boys.
