The dimorphic development of male and female vertebrates, including humans, and the physiological processes involved in their respective contributions to reproduction are coordinated by a variety of hormones. They include specific sex hormones which are predominantly produced by the ovaries and testes. They are also called gonadal steroid hormones, the principal ones being classified as oestrogens, androgens and progestogens (progestins).
Keywords: reproduction; ovary; testis; steroid hormones
