The patient, in this case, is a 15-year-old female who presented with primary amenorrhea and who on work-up was found to have complete androgen insensitivity syndrome. Here, Dr. Canon at the University of Arkansas for Medical Sciences performs a prophylactic laparoscopic bilateral gonadectomy to reduce her future risk for intra-abdominal testicular malignancies.
