As in other mammalian species the oviducts play an important role in storage of sperm, fertilization and early embryonic development. Unlike other mammals though the oviducts are enlarged at the uterine end and this unique arrangement allows prolonged storage of large numbers of spermatozoa. | As in other mammalian species the oviducts play an important role in storage of sperm, fertilization and early embryonic development.
