The past adventures of Uterus Man and his brother

Having recently enjoyed The Adventures of Uterus Man, we turn now to the past adventures of Uterus Man and his brother. Those are detailed in a study:

Two male sibs with uterus and Fallopian tubes. A rare, probably inherited disorder,” S. Armendares, L. Buentello, and S. Frenk, Clinical Genetics, vol. 4, no. 3 (1973): 291-296. The authors, at Instituto Mexicano del Seguro Social, report:

“Two male sibs (46, XY) with normal penis and scrotum as well as bilateral cryptorchidism are reported. Intraabdominal uterus and Fallopian tubes were found. The pathogenesis and the possible inheritance of this developmental defect are discussed.”

(Thanks to investigator Leila Francis for bringing this to our attention.)
