Abstract
Complete androgen insensitivity syndrome (CAIS) is a rare and complicated endocrine condition in which individuals inherit a female phenotype but a male karotype of 46XY. It occurs as a result of a defect on the X chromosome inhibiting the effect of androgens during embryological development.
