Note this section of notes refers to the development of the gonad as an endocrine organ. A detailed description of the gonad development is covered in Ovary Development and Testis Development.
In particular, endocrine development of the testis is required for development of both the internal genital tract and the external genitalia.

Gonad Development
- mesoderm - mesothelium and underlying mesenchyme, primordial germ cells
- Gonadal ridge - mesothelium thickening, medial mesonephros
- Primordial Germ cells - yolk sac, to mesentery of hindgut, to genital ridge of developing kidney
Differentiation
- testis-determining factor (TDF) from Y chromosome: presence (testes), absence (ovaries)
Testis
- 8 Weeks, mesenchyme, interstitial cells (of Leydig) secrete testosterone, androstenedione
- 8 to 12 Weeks - hCG stimulates testosterone production
- Sustentacular cells - produce anti-mullerian hormone to puberty
Ovary
- X chromosome genes regulate ovary development
Steroidogenesis
