The Uterus is the organ of pregnancy as this is where implantation and development of the feotus occurs. The Uterus is the reproductive organ with the most species variations. These variations occur in both the anatomical types of uterus aswell as the uterine horn appearance and endometrial linings.

'''Duplex Uteri'''
* rabbits and marsupials
'''Bicornuate Uteri'''
*(previously Bipartite Uteri)
*A high degree of paramesonephric duct fusion leads to a uterine body and short poorly developed uterine horns as seen in the Mare.
*An intermediate degree of fusion leads to moderately developed uterine horns as in the Cow, Sheep and Goat.
*A low degree of fusion of the paramesonephric ducts leads to long uterine horns and a small uterine body as seen in the sow, bich and queen.
*This varying degree of paramesonephric duct fusion reflects the species differences in litter sizes. as either monotocous or polytocous animals
'''Simplex Uteri'''
*complete fusion of the paramesonephric ducts forming a single uterine body with no uterine horns. This is seen in primates and especially humans.
