The pediatric radiologist plays a significant role in the evaluation and the treatment of infants with ambiguous genitalia. On the first day of life, an investigation should be initiated that includes studies, in particular a sonogram, to demonstrate the presence or absence of a uterus, and a genitogram to define the presence of a vagina. Once gender assignment has been made, information regarding the size of the vagina and its position in regard to the urogenital sinus becomes essential to the pediatric urologist when planning a course for reconstruction. Herein we break down intersex states into four major categories: female pseudohermaphroditism, male pseudohermaphroditism without müllerian structures, and male hermaphroditism with müllerian structures and true hermaphroditism. The role of the radiologist in each of these states is discussed.
Gender verification testing in sport, first introduced in 1966 by the International Amateur Athletic Federation (IAAF) in response to fears that males with a physical advantage in terms of muscle mass and strength were cheating by masquerading as females in women's competition, has led to unfair disqualifications of women athletes and untold psychological harm. The discredited sex chromatin test, which identifies only the sex chromosome component of gender and is therefore misleading, was abandoned in 1991 by the IAAF in favour of medical checks for all athletes, women and men, which preclude the need for gender testing. But, women athletes will still be tested at the Olympic Games at Albertville and Barcelona using polymerase chain reaction (PCR) to amplify DNA sequences on the Y chromosome which identifies genetic sex only. Gender verification testing may in time be abolished when the sporting community are fully cognizant of its scientific and ethical implications.
