Gonadal agenesis is a rare condition where an individual lacks both
gonads.
If the
karyotype is
46,XY and the individual otherwise has a male phenotype, it is called anorchia; this occurs in one of 20,000 male births.[1] The corresponding condition in an individual with a female phenotype and
46,XX phenotype is called bilateral ovarian agenesis. However, gonadal agenesis is more common in people with an 46,XY karyotype.[2]
