Reproductive Systems. Today we are going to learn about our origin, lets learn about the human reproduction. The gonadal primordium is the only tissue in mammals that has two divergent developmental fates, leading ultimately to the formation of either a testis or an ovary (Cederroth et al, 2007). The female reproductive system consists of the primary as well as accessory sex organs. Other systems in the body, such as the endocrine and urinary systems, work continuously to maintain homeostasis for survival of the individual. Reproductive System 8.
