A Case of Normal Uterus With Bicollis and Vaginal Septum: A Challenge to the Classical Theory of Mullerian Duct Fusion

Figures

↓  Figure 1. Development of female internal genitalia. (a) Undifferentiated gonads are present with Mullerian ducts lateral to mesonephric ducts cranially and medial caudally. (b) In females, mesonephric ducts regress as Mullerian ducts fuse and the septum is resorbed. (c) Uterus, cervix, and upper vagina, with mesonephric remnants such as the epoophoron, paroophoron, and Gartner’s duct cysts [5].
