2History 1817: 1st report of a woman with un-descended testes by a Dr. Diefferbach 1st provided evidence of a hereditary pattern.1937: Dr. discovered any female with AIS was genetically male.1993: Anne Fausto-Sterling proposed a pan for 5 gender categories.
3Symptoms No extragenital abnormalities. Two nondysplastic testes. (are inside body)No fallopian tubes, uterus, and cervix but a short vagina.Undermasculinization of extra genetalia at birth. (very little or no male parts.)Impaired spermatogenesis and/or somatic virilization at puberty. (no production of sperm or egg)
4InheritanceUsually from the mother with an altered copy of the carrier AR gene.46XY Karytype and affected.46XY Karytype and unaffect.46XX Karytype and a carrier.46XX Karytype and not a carrier.
5It affects 2 to 5 per 100,000 people who are genetically male. FrequencyIt affects 2 to 5 per 100,000 people who are genetically male.
6Locus Mutations in the AR gene. usually the AR gene provides instructions for making a protein called an androgen receptor.Mutations prevent androgen receptors from working properly, and prevents cells from using the hormones properly.
7It affects sexual development before birth and during pregnancy. Age of OnsetIt affects sexual development before birth and during pregnancy.
8Males (genetically) with a mutation in the X- chromosome. Affected GroupsMales (genetically) with a mutation in the X- chromosome.
9Treatment Hormone Replacement Therapy Mostly consists of estrogen replacement.Psychological SupportParents are the biggest client for support.Surgical CareVaginal lengthening or orchidectomy. (remove a testicle and spermatic cord.)
10PrognosisFor complete AIS, it’s good if at risk testicular tissue is removed at the right time.The outlook for incomplete AIS depends on the presence and severity of ambiguous genitalia.
