People with this condition are fertile, with the ability to father children, but may be raised as females due to ambiguous or feminized genitalia. [ 18 ] [ 19 ] 17β-Hydroxysteroid dehydrogenase deficiency – a condition characterized by impaired androgen and estrogen synthesis in males and females, respectively.
Chromosomal abnormalities causing female infertility include Turner syndrome. Oocyte donation is an alternative for patients with Turner syndrome. [36] Some of these gene or chromosome abnormalities cause intersex conditions, such as androgen insensitivity syndrome.
A zygote with only X chromosome (XO) results in Turner syndrome and will develop with female characteristics.
