Swyer syndrome was first formally described by London endocrinologist Dr. Gerald 'Gim' Swyer in 1955, marking a significant moment in the understanding of sex development disorders. This rare condition, also known as 46,XY complete gonadal dysgenesis, would come to redefine medical comprehension of how genetics influence physiological sex characteristics, even when an individual's chromosomal makeup is different from their external appearance.

Estimates suggest around 0.018% to 1.7% of the population have intersex traits, a biological reality sometimes inaccurately described by the outdated phrase "half man half woman syndrome". This colloquial term is a misnomer, as it fails to capture the complexity and diversity of variations in sex characteristics that exist naturally.
