Primordial germ cells reach gonadal ridge Primordial germ cells migrate to the urogenital ridges Primordial germ cells migrate to the hindgut However, since there are significant differences in gonadal development between birds and mammals, these mechanisms need to be explored to establish whether they are conserved amongst vertebrates. The molecular mechanisms underlying the specific location of the gonads on the surface of the mesonephroi begin to be unveiled in chicken embryos, where Sonic hedgehog (SHH) signaling mediated by the bone morphogenetic protein 4 (BMP4) establishes the dorsoventral patterning of the mesoderm and induces coelomic epithelium cell ingression, thus probably initiating gonadal development ( 2). The mesonephroi also give rise to components of the internal reproductive tract and of the urinary system. Gonads are subsequently colonized by the primordial germ cells, of extra-gonadal origin. The gonadal ridge is bipotential and can develop into an ovary or a testis. The adreno-gonadal ridge is the common precursor of the gonads and adrenal cortex. Each urogenital ridge divides into a urinary and an adreno-gonadal ridge in the 5 th week ( Table 1). In the human, they develop during the 4 th week post-fertilization at the ventral surface of the cranial mesonephroi, and are formed by intermediate mesoderm covered by coelomic epithelium. The urogenital ridges are the common precursors of the urinary and genital systems and of the adrenal cortex ( 1).

For complete coverage of all related areas of Endocrinology, please visit our on-line FREE web-text, The Gonadal Ridge Here we review the sexually undifferentiated stage of embryonic development, and the anatomic, histologic, physiologic and molecular aspects of the fetal sexual differentiation of the gonads, the internal reproductive tract and the external genitalia. Subsequently, internal and external genitalia will follow the male pathway in the presence of androgens and anti-Müllerian hormone (AMH), or the female pathway in their absence. The presence or absence of primordial germ cells, of extragonadal origin, also has a sexually dimorphic relevance. Believed initially to be governed entirely by the presence or absence of the SRY gene on the Y chromosome, gonadal determination has proven to rely on a complex network of genes, whose balanced expression levels either activate the testis pathway and simultaneously repress the ovarian pathway or vice versa.

Sex differentiation involves a series of events whereby the sexually indifferent gonads and genitalia progressively acquire male or female characteristics. However, 6 weeks elapse in humans before the first signs of sex differentiation are noticed.
