Puberty
Puberty occurs around ages 9-13 in females, and 10-13 in males where the reproductive system starts to develop maturely.
Puberty is under control of a number of sex hormones produced by glands such as the pituitary, testes(in males), and ovaries (in females).

Puberty and Sex Hormones
How does it begin?
Puberty begins when GnRH is released from the hypothalamus and acts on the anterior pituitary causing secretion of the following protein hormones:
1. Follicle Stimulating Hormone (FSH)
2. Luteinizing Hormone (LH)
FSH and LH stimulate the ovaries to secrete the steroid hormone:
1. Estrogen- activates the development of most secondary sex characteristics.
