Four types of uterine malformations. The uterus is formed during embryogenesis by the fusion of the two paramesonephric ducts (also called Müllerian ducts). This process usually fuses the two Müllerian ducts into a single uterine body but fails to take place in these affected women who maintain their double Müllerian systems.
The superior part of the Müllerian ducts do not fuse and form the left and right fallopian tubes. Disruptions to this stage of development can result in didelphys or bicornuate uteri anomalies. [8] In both didelphys and bicornuate uteri, the non-fusion of the Müllerian ducts results in two distinct uterine cavities.
Didelphis is a genus of New World marsupials. The six species in the genus Didelphis , commonly known as Large American opossums , are members of the opossum order , Didelphimorphia . The genus Didelphis is composed of cat -sized omnivorous species, which can be recognized by their prehensile tails and their tendency to feign death when cornered.
A bicornuate uterus is an indication for increased surveillance of a pregnancy, though most women with a bicornuate uterus are able to have healthy pregnancies. [1] Women with a bicornuate uterus are at an increased risk of recurrent miscarriage, [2] [10] preterm birth, [2] [11] malpresentation, [2] [12] disruptions to fetal growth, [13] premature rupture of membranes, placenta previa and ...

The largest difference between the opossum and non-marsupial mammals is the bifurcated penis of the male and bifurcated vagina of the female (the source of the term didelphimorph, from the Greek didelphys, meaning "double-wombed"). [38] Opossum spermatozoa exhibit sperm-pairing, forming conjugate pairs in the epididymis.
