Term
Gonadal and Genital Differentiation in Males
Definition

- Bipotential gonad --> Default pathway is to ovaries

- SRY gene --> Bipotential gland becomes a testis

- Testis then produce Leydig cells and Sertoli Cells

- Leydig cells: Produce SF-1 --> Testosterone --> Induces formation of male internal genitalia

- Sertoli cells: Produce WT1 and SF-1 --> Produce MIS-R --> Induces regression of Mullerian duct

- External genitalia: Formed via DHT production and effect

Term
Gonadal and Genital Differentiation in Females
Definition
