Secondary sex characteristics in females:

1. Among females, estrogen is the hormone responsible for the development of secondary sexual characteristics.
2. On reaching puberty and the start of menarche, secondary sexual features found among females are the development of breasts and reproductive system, change in the external genitalia and the growth of axial and pubic hair.

Secondary sex characteristics in males:

1. In males, Testosterone is the hormone responsible for secondary sex traits.
2. Puberty among men is characterized by a change in voice, growth of axial and pubic hair, and development of external genitalia.

Estrogen (females) and Testosterone (males) are the two hormones responsible for secondary sex characteristics among humans.
