Zulkishura Gonadal dysgenesis Psychological support should also be offered to patients and their families. Etiology Although the etiology is not completely understood, 46,XY CGD results from failure of testicular development due to disruption of the underlying genetic pathways and several genes have been implicated: Systemic arterial hypertension was only diagnosed in the patient with 17 alpha-hydroxylase deficiency, and gonadal malignization, in the one with XY PGD.

Mutations in SOX9, the gene responsible for campomelic dysplasia and autosomal sex reversal. Differential diagnosis The differential diagnosis should fonadal other causes of POF, as well as 46,XY complete gonadal dysgenesis see these terms. Infertility is an important management issue; however, pregnancy may be feasible through zygote egg donation. You can help by adding to it.

Management and treatment Management should include hormone replacement therapy. Disgenesia gonadal XY Infertility is an important management issue; however, pregnancy may be feasible through zygote egg donation. Environmental factors maternal progesterone intake during pregnancyand impaired prenatal growth have also been associated with 46,XY CGD.

Amenorrhea, Y chromosome, Sexual differentiation, Androgen receptors, Testosterone, Dihydrotestosterone, 46,XY gonadal dysgenesis, 17 alpha-hydroxylase. Management and treatment Management should involve removal of streak gonadal tissue as there is a high risk for malignancy.
