It is a form of gonadal dysgenesis, meaning that a person with this variation will have streak gonads that do not produce hormones. Since they do not produce testosterone, their body does not develop a penis and usually develops a vulva and vagina instead. Since they do not produce another hormone known as anti-Müllerian hormone (AMH), people with Swyer syndrome often develop a uterus and fallopian tubes as well. They will not usually start puberty or begin menstruating, but some people with Swyer syndrome do menstruate (without ovulating) if they receive estrogen therapy.
