Androgen insensitivity syndrome (AIS) is a genetic X-linked recessive disorder where affected males have mostly female sex characteristics or signs of both male and female sexual development. Individuals with this condition are genetically male; they contain both an X and Y chromosome (Barbaro et al., 2007). Mutations in the androgen receptor gene are what cause androgen insensitivity syndrome in individuals. This gene produces androgen receptors which are important to males. Without this receptor androgen will not be supplied to the body and that is a major hormone males need. Other names used in place of AIS are as follows; Testicular Feminization Syndrome (TFM), Androgen Receptor Deficiency, Androgen Resistance Syndrome, AR Deficiency, Dihydrotestosterone Receptor Deficiency, and DHTR Deficiency (OMIM, 2012). Androgen insensitivity syndrome can be considered as complete androgen insensitivity syndrome, partial androgen insensitivity syndrome, or mild androgen insensitivity syndrome.
Complete androgen insensitivity syndrome occurs when the body is unable to use androgens at all. Affected individuals with this form have the external sex characteristics of females, but do not have a uterus, will not menstruate, and are infertile. They also will not have axillary or pubic hair, or acne which is linked to puberty. Androgen insensitivity syndrome individuals develop internal male sex organs. Partial androgen insensitivity syndrome (Reifenstein syndrome) is when the body’s tissues are partially sensitive to the effects of androgens. Affected individuals can have normal female sex characteristics, both male and female sex characteristics, or normal male sex characteristics. An individual may be brought up as a male then u...

In this essay, the author

  • Opines that finding common variants of androgen receptors can help us find where the mutations are coming from. studies need to be done to find a way to prevent the syndrome.
  • Explains grino, griffin, cushard, w. g., jr. and wilson, j. d.
  • Opines that wisniewski, a. b., migeon, c. j, meyer-bahlburg, h. f.
  • Explains that androgen insensitivity syndrome is a genetic x-linked recessive disorder where affected males have mostly female sex characteristics or signs of both male and female sexual development.
  • Explains that androgen insensitivity syndrome affects sexual development before birth and during puberty. it is inherited by an x-linked recessive disorder.
  • Explains that androgens are tested with the insulin-like growth factor (igf) system in cultured genital skin fibroblasts.
  • Explains that androgen insensitivity syndrome is when the genitals and reproductive organs are affected.
  • Explains that androgen insensitivity syndrome does not essentially have a cure or treatment.
