Question

What changes are noticed in the sexual maturity of human beings?

Answer 1

Hint: Puberty and adolescence are two terms that are often used interchangeably to describe certain changes and periods of change. The physical changes that lead to sexual maturity in a boy or a girl are referred to as puberty. Adolescence is the period of a boy or girl's life when psychological and social changes occur. The cause of adolescence is puberty, which can last anywhere from one person to another.

Complete answer:
The body changes dramatically as a result of growth and maturation in both men and women. The rate of development accelerates during adolescence. There are some differences in the characteristics of boys and girls when it comes to reproduction. Primary sexual characteristics are those that are inherited, whereas secondary sexual characteristics are those that are acquired.
Secondary sexual characters refer to the changes that occur in humans as they reach sexual maturity. Some of these changes are shared by both genders, while others are unique to one gender.

The following are changes that both sexes experience:
1. Hair growth in the armpits and genital area.
2. Armpit and genital area darkening.
3. The appearance of fine hair on the arms, legs, and face.
4. Growth in stature.

The changes that are taking place in girls are as follows:
1. Breasts and hips enlargement.
2. Darkening of the nipple area.
3. Menstruation has begun.
4. The voices become more high-pitched.

The following are the changes that are occurring in boys:
1. On the face, there appears to be a lot of thick hair.
2. The voice is cracking.

Note:
The male sex hormone testosterone is produced in the testicles. Testosterone levels are crucial for normal male sexual development and function. During puberty (adolescence), testosterone aids the development of male characteristics such as body and facial hair, a deeper voice, and muscle strength in boys. Estrogen is a hormone that has several functions in the body. It aids the development and maintenance of the female reproductive system as well as female characteristics such as breasts and pubic hair in females.
