Normal Radiological Anatomy
In the 6th week of the embryo development the morphological sexual characteristics of both sexes start to establish themselves. In every embryo, on both sides of the middle line, the following structures are present: (i) a genital septum; (ii) a Wolf mesenteric duct, beside the genital septum; (iii) a paramesonephric Müllerian duct that consists of three segments: (a) a vertical cranial sector beside the Wolf duct; (b) a middle horizontal sector that passes in front of the Wolf duct; and (c) an inferior or caudal sector. According to the established sex at the moment of fertilization, the absence of the Y chromosome clears the way for the differentiation in the female sense, establishing the retraction of the Wolf ducts, the development of the structures derived of the Müller paramesonephric ducts and the formation of the ovaries.
