*(Previously Bipartite Uteri) Bicornuate uteri have a relatively small uterine body and two uterine horns of varying development.

*A releatively large uterine body and short, poorly developed uterine horns, as seen in the Mare, are due to a high degree of paramesonephric duct fusion.

*A relatively large uterine body and short, poorly developed uterine horns, as seen in the mare, are due to a high degree of paramesonephric duct fusion.

*Moderately developed uterine horns as in the cow, ewe and goat arise due to an intermediate degree of fusion.

*Long uterine horns and a small uterine body as seen in the sow, bitch and queen arise due to a low degree of fusion of the paramesonephric ducts.  

*Long uterine horns and a small uterine body as seen in the sow, bitch and queen arise due to a low degree of fusion of the paramesonephric ducts.  

*This varying degree of paramesonephric duct fusion reflects the species differences in litter sizes, Monotocous species having short horns and polytocous animals having much longer uterine horns.

'''Simplex Uteri'''

'''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.
