Question

Define puberty?

Answer 1

Puberty:

1. The age at which the sex hormones (or gametes) begin to be produced, and the boy and the girl become sexually mature (able to reproduce) is called puberty.
2. When the brain begins to release a hormone called gonadotropin-releasing hormone, puberty begins.
3. This causes the pituitary gland to secret additional hormones, including luteinizing hormone (LH) and follicle-stimulating hormone (FSH).
4. The release of sex hormones from the gonads is aided by LH and FSH.
5. Most of the changes in the sexual characteristics and reproductive organs occur throughout puberty and are caused by sex hormones.
6. Puberty normally begins in boys between the age of 11 and 12 and girls between the age of 9 and 10.
7. In puberty, secondary sexual characteristics develop in boys and girls.
