It does not significantly impair female genital or sexual development. The insensitivity to androgens is therefore clinically significant only when it occurs in genetic males, (i.e. individuals with a Y-chromosome, or more specifically, an SRY gene)….

Are people with AIS female?
A person with complete AIS appears to be female but has no uterus. They have very little armpit and pubic hair. At puberty, female sex characteristics (such as breasts) develop. However, the person does not menstruate and become fertile.
Are CAIS female?
Most individuals with CAIS are raised as females. They are born phenotypically female and usually have a heterosexual female gender identity; However, at least two case studies have reported male gender identity in individuals with CAIS.
Do people with CAIS have vaginas?
Girls with CAIS do not have a womb or ovaries, so are unable to get pregnant. Their vagina will also be shorter than normal, which may make some sexual acts difficult.
Is Pais male or female?
Partial androgen insensitivity syndrome (PAIS) is genetic condition that affects the sexual development of a male fetus. During pregnancy, male fetuses with PAIS are unable to properly respond to male sex hormones (androgens). As a result, this affects the development of the genitals.
Can a girl be born with male hormones?
People with this syndrome are genetically male (they carry both an X and a Y chromosome), but are born with all or some of the physical traits of a female. This happens because a mutation on the X chromosome causes the body to resist androgen, the hormones that produce a male appearance.
What is an XY female?
In this system, the sex of an individual is determined by a pair of sex chromosomes. Females have two of the same kind of sex chromosome (XX), and are called the homogametic sex. Males have two different kinds of sex chromosomes (XY), and are called the heterogametic sex.
What causes androgen insensitivity?
What causes androgen insensitivity? Androgen insensitivity is a genetic mutation on the X chromosome that can be inherited from the mother or happen as a spontaneous genetic change at conception. This mutation prevents the body tissue from using male hormones (androgens) during fetal development and after birth.
Do people with AIS have periods?
Can people with PAIS have kids?
Androgens are most important during early development in the womb. People with PAIS can have a normal lifespan and be totally healthy, but they may have difficulty conceiving a child.
What is the difference between partial androgen insensitivity syndrome?
Partial androgen insensitivity syndrome (PAIS) is a condition that results in the partial inability of the cell to respond to androgens. It is an X linked recessive condition….

What is an XY woman?
XY gonadal dysgenesis, also known as Swyer syndrome, is a type of hypogonadism in a person whose karyotype is 46,XY. Though they typically have normal female external genitalia, the person has functionless gonads, fibrous tissue termed “streak gonads”, and if left untreated, will not experience puberty.
What is androgen insensitivity syndrome (AIS)?
Androgen Insensitivity Syndrome (AIS) is a human disorder in which an individual’s genetic sex (genotype) differs from that individual’s observable secondary sex characteristics (phenotypes). A fetus with AIS is genetically male with a 46,XY genotype. The term 46,XY refers to the chromosomes found in most cells of the fetus.
What is partial androgen insensitivity (Reifenstein syndrome)?
People with partial androgen insensitivity (also called Reifenstein syndrome) can have genitalia that look typically female, genitalia that have both male and female characteristics, or genitalia that look typically male. They may be raised as males or as females and may have a male or a female gender identity.
How is partial androgen insensitivity syndrome (PiS) treated?
Treatment for partial androgen insensitivity syndrome may include corrective surgery to match gender identity. If your child identifies as male, hormone therapy will include testosterone. Ongoing psychological support is an important part of treatment. Parents of a newly diagnosed child may benefit from counseling as well.
What tests are used to diagnose androgen insensitivity?
Partial androgen insensitivity may be diagnosed at birth because of the presence of male and female sexual traits. Tests used to confirm this condition include blood work to check hormone levels, genetic testing and pelvic ultrasound. Complete androgen insensitivity syndrome is treated with estrogen replacement therapy after puberty.
