ABSTRACT
The reproductive organs have a primary function in producing gametes and the hormones that support reproductive function. In males, the tract is specialized for the delivery of gametes to enable fertilization. In females, the major role is in providing an environment for fertilization and then the development of the conceptus to a suitable degree of maturity before its birth. The female reproductive organs consist of a pair of ovaries, two oviducts, a uterus and cervix, vagina, and the vulva. There is considerable variation among species in the anatomic organization of the oviducts and uterus. The oviducts, also known as the uterine tubes or fallopian tubes, provide a means of communication between the infundibulum and the cornua, or horns, of the uterus. The reproductive organs of the male include the gonads, testes, the spermatic ducts, accessory glands, and the penis. The primary spermatocyte divides by meiotic and then mitotic mechanisms to give rise to four spermatids.
