Marcella is diagnosed with complete androgen insensitivity syndrome.
Complete androgen insensitivity syndrome is an intersex condition which occurs due to complete inability of the body to respond to androgenic hormones such as testosterone. This condition occurs to genetically male individuals (who has one X and one Y chromosome). Affected individuals have the external sex characteristics of females, but do not have a uterus and therefore are unable to menstruate.
