How many stages in boys puberty?

Puberty in boys typically progresses through four stages:

1. Prepuberty:

- This is the stage before puberty begins, usually starting around the age of 10.

- During this stage, boys will experience few physical changes, but their bodies will start to produce hormones that signal the start of puberty.

- These hormones, called gonadotropin-releasing hormone (GnRH), follicle-stimulating hormone (FSH), and luteinizing hormone (LH), will cause the testes to produce testosterone.

2. Early Puberty:

- This stage begins around age 11 or 12.

- The first noticeable change is the growth of the testes and scrotum.

- Boys may also start to develop pubic hair and experience erections.

- Their voices may start to deepen, and their skin may become oily and prone to acne.

3. Mid-Puberty:

- This stage typically begins around age 13 or 14.

- During this stage, boys experience a rapid growth spurt, and their muscles start to develop.

- Their voices continue to deepen, and their facial hair begins to grow.

- They may also start to produce semen, which is the fluid that carries sperm.

4. Late Puberty:

- This stage begins around age 15 or 16 and can last until age 18 or 19.

- During this stage, boys continue to grow and develop physically.

- Their reproductive systems become fully mature, and they are able to father children.

- Boys also experience changes in their emotional development and start to develop a sense of identity.
