Rectal palpation and transrectal ultrasound could not reveal the presence of female gonads. Urethral ultrasound revealed the pelvic urethra and the openings of the male accessory glands. The equine was subjected to hormonal challenge with human chorionic gonadotropin (hCG). First sample presented a testosterone concentration of 20 ng/dL; [...]
