Embryology of Testicular Descent and Maldescent

  • F. Hadžiselimović


During the development of the male genital tract two different stages can be discerned:
  1. 1.

    The initial stage is generally called an indifferent stage, lasting until the end of the 6th week after conception [1]. In this period the male and female genital tracts develop similarly, so that at the end of this phase both male and female embryos have an urogenital anlage with Wolffian and Müllerian ducts .

  2. 2.

    The second stage commences at the 7th week post conception (p.c.) and is clearly recognizable at the 8th week p.c. [2, 3]. This is the period when the differentiation of the testes, the epididymis, and the external genitalia occurs.
