HORMONES ROLE IN REPRODUCTIVE FUNCTION

Endocrine glands release hormones into the bloodstream to reach a particular body part called target site. The target site responds to the hormone. There are many endocrine glands or ductless glands in the body The testes and ovaries secrete sex hormones. You have just learnt that these hormones are responsible for the male and female secondary sexual characters. Further, the sex hormones are under the control of hormones from the pituitary gland (Fig. 10.3). The pituitary secretes many hormones, one of which makes ova mature in the ovaries and sperms form in the testes.
