46,XY karyotype syndrome, also known as Swyer syndrome or 46,XY gonadal dysgenesis, is a condition where individuals have male chromosomes (46,XY) but develop female characteristics. This happens due to non-functional gonads, typically resulting in female external genitalia and an absence of secondary sexual characteristics. Hormone replacement therapy is often recommended.
