Resumen:

This chapter explains the evolution and development of the external male genitalia, from the undifferentiated genital tubercle, at approximately the 4th week of gestation, until formation and differentiation is completed at around week 11th of gestation. Understanding this stage allows us to identify the presence of congenital malformation of male external genitalia and its cause. External genitalia are the reproductive organs necessary for efficient copulation and internal fertilization in various species. In mammals, male and female external genitalia, the penis and the clitoris, are derived from a common primordium: the genital tubercle (GT). The development of the GT can be subdivided into a three-step process, that finally results in sexual differentiation of the external genitalia. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2022.
