Steroid

A natural organic compound produced from lipids, specifically cholesterol. Sex-related steroids are produced mainly by the testicles and ovaries, which control the physiology of reproduction and secondary sexual characteristics. In women, these hormones are called estrogens and progesterone; in the end they are called testosterone and androsterone. Research into these compounds has allowed them to be synthesized, as with the artificial hormones used in contraceptives.
