The uterus is the most important reproductive organ present in the pelvis, a constituent of the internal female reproductive tract which develops from a paired paramesonephric duct, originating from coelomic epithelium extending beside the mesonephric ducts.
At 18 gestational days the ovary could be observed histologically in this species, and through immunohistochemistry we confirmed only the positive marking on the germinal epithelium and the paramesonephric ducts (Figs.
The Wolffian (mesonephric) and Mullerian (paramesonephric) ducts form in both sexes.

Thus, the cranially located appendix testes and caudally located prostatic utricle are typically the only vestigial structures derived from paramesonephric ducts [14].
The Mullerian ducts, also called the paramesonephric ducts, are derived from the mesoderm in embryos of both genders but only go on to develop the reproductive organs in females and degenerate in males.
According to this theory, the fallopian tubes develop from paramesonephric channel remnants in the 6-7th weeks of gestation in the embryologic period [5].
Therefore, imaging studies of the urinary tract are fundamental in paramesonephric duct anomalies, particularly in the HWW syndrome.
Nevertheless, cystic ovaries reported in mammalians, including guinea pigs, horses, swine, rabbits, cattle, and aged rats, have been interpreted as to have been derived from corpora lutea, ovarian follicles, ovarian surface epithelium, remnants of rete ovarii, or mesonephric and paramesonephric ducts [25-27].
Hymen is formed from the epithelial lining of paramesonephric ducts and urogenital sinus at vestibulo vaginal junction.
It is postulated that these tumours arise from mullerian or paramesonephric duct remnants, which were deposited when the ovary descended during embryogenesis.
Sinowatz (2010) describes that the vagina has two origins: one anterior, derived from the paramesonephric ducts and one posterior derived from the urogenital sinus.
