Sex Determinationiation of the gonad into a testis or ovary. The gonad develops as an undifferentiated primordium that is initially indistinguishable between XX (female) and XY (male) embryos; the gonad is a uniquely bipotential organ in its ability to give rise to a testis or ovary.

Male Sexual Differentiationdges contain three main types of bipotential precursor cells: supporting cells, which in the developing testis differentiate into Sertoli cells, steroidogenic cells giving rise to Leydig cells, and primordial germ cells developing into sperm.
