XY complete gonadal dysgenesis, also known as Swyer syndrome, is a type of defect hypogonadism in a person whose karyotype is 46,XY. Though they typically have normal vulvas , [ 1 ] the person has underdeveloped gonads, fibrous tissue termed " streak gonads ", and if left untreated, will not experience puberty .
Turner syndrome was first described independently by Otto Ulrich in 1930 and Henry Turner in 1938. [29] 46,XX pure gonadal dysgenesis was first reported in 1960. [29] 46,XY pure gonadal dysgenesis, also known as Swyer syndrome, was first described by Gim Swyer in 1955. [29]
Swyer syndrome (Pure Gonadal Dysgenesis or XY gonadal dysgenesis) – a type of hypogonadism in a person whose karyotype is 46,XY. The person is externally female with streak gonads, and left untreated, will not experience puberty.
Hypergonadotropic hypogonadism (HH), also known as primary or peripheral/gonadal hypogonadism or primary gonadal failure, is a condition which is characterized by hypogonadism which is due to an impaired response of the gonads to the gonadotropins, follicle-stimulating hormone (FSH) and luteinizing hormone (LH), and in turn a lack of sex steroid production.

Meanwhile, XY gonadal dysgenesis is known as PGD, 46,XY or Swyer syndrome. Patients with PGD have a normal chromosomal constellation but may have localized genetic alterations. XX gonadal dysgenesis is related to Swyer syndrome, since both conditions have the same phenotype and clinical issues; however in Swyer syndrome the karyotype is 46,XY ...
46, XY gonadal dysgenesis, also known as Swyer syndrome 46, XX male syndrome , also known as de la Chapelle syndrome In this list, the karyotype is summarized by the number of chromosomes, followed by the sex chromosomes present in each cell.
The condition also occurs in XY males, as they suffer from the effects of low cortisol and salt-wasting, not virilization. Persistent Müllerian duct syndrome – A rare type of pseudohermaphroditism that occurs in 46 XY males, caused by either a mutation in the Müllerian inhibiting substance (MIS) gene, on 19p13, or its type II receptor ...
