title: A case of homosexual murder: a victim with testicular regression syndrome.
abstract: A 25-year-old male was killed with a survival knife by his business and homosexual partner. In addition to 22 wounds on the extremities, 16 wounds were found on the neck, chest and abdomen. The heart and lungs were penetrated, and three wound tracks reached the back of the body. The cause of death was diagnosed as hemorrhage. The genitalia of the victim was anomalous: the pubic hair pattern was that of a female, the penis was small and no testes were identified in the scrotal sac. According to his medical records, micropenis and bilateral cryptorchidism were present at birth, and neither hormonal treatments nor bilateral orchidopexy could enlarge his penis size. At the age of 17, his condition had been diagnosed as hypergonadotropic hypogonadism. His genital anomalies were considered due to embryonic testicular regression syndrome, and his micropenis a possible cause of his homosexual orientation. Judging from the patulous anus with thickened margins, he was probably a passive homosexual. The motive of the murder was not monetary, but rather emotional entanglement. The court judged that the case was one of premeditated murder with a short-circuited motive, and sentenced the defendant to ten years imprisonment.
