Regulation[edit] The gonads are controlled by luteinizing hormone and follicle-stimulating hormone, produced and secreted by gonadotropes in the anterior pituitary gland.[3] This secretion is regulated by gonadotropin-releasing hormone produced in the hypothalamus.[4][5]


Development[edit] Main article: Development of the gonads Gonads start developing as a common primordium (an organ in the earliest stage of development), in the form of gonadal ridges,[6] and only later are differentiated to male or female sex organs. The presence of the SRY gene,[7] located on the Y chromosome and encoding the testis determining factor, determines male sexual differentiation. In the absence of the SRY gene from the Y chromosome, the female sex (ovaries instead of testes) will develop. The development of the gonads is a part of the development of the urinary and reproductive organs.
