Summary

Individuals with androgen insensitivity have a 46,XY karyotype and testes that produce age-appropriate androgen levels but have undermasculinized external genitalia due to defects in androgen action. The phenotype in PAIS varies depending on residual androgen receptor function, ranging from severe undermasculinization presenting as female-like external genitalia to male-appearing genitalia. The typical presentation comprises micropenis, severe hypospadias, and bifid scrotum with or without cryptorchidism (summary by Mongan et al., 2015). [from OMIM]
