What are sex hormones? Why are they named so? State their functions.

Dear Student

The hormones which help and control the formation of secondary sexual characters are called sex hormones. They are called sex hormones because they control the sexual activities and help us to distinguish boys from girls.
The sex hormones help to delop the secondary sexual characters. Such as, in boys they control formation of sperms by testes and growth of facial hair. In girls they help to develop breasts, milk secreting glands or mammary glands.

Thanks
