The male reproductive organs produce the male gametes, the spermatozoans. These are introduced into female reproductive system, where they fuse with the sperm to form zygote. The reproductive system(bull) is compsed of the following parts; i). Testes ii). Epididymis iii). Sperm ducts iv). Accessory glands(Seminal vesicles and prostrate glands) v). Penis The ovary is the primary female reproductive organ and has two important functions: producing the female reproductive cell (the egg or ovum) and producing the hormones estrogen and progesterone. The cow's two ovaries are oval to bean-shaped organs that are 1—1.5 inches long and located in the abdominal cavity. The secondary sex organs are a series of tubes that receive semen, transport sperm to the egg so it can be fertilized, nourish the fertilized egg (embryo), and allow the calf to be birthed. These organs include the vagina, cervix, uterus, uterine horns, and oviducts (also called Fallopian tubes), which each have a funnel-shaped opening called the infundibulum.
