F5, a 62-year-old male, experienced sensorineural hearing loss, self-observedanosmia, and bilateral cryptorchidism, with initial lab results showing lowtestosterone levels of 140 ng/dL and suppressed gonadotropins, including LH at 0.27mIU/mL and FSH at 0.85 mIU/mL. This evidence concerns the gene BRD2 and cryptorchidism.
