Figure 1 Sister 1. (A) Left elongated gonad visualized at laparoscopy. Adjacent to the gonad is a tubal structure with distal fimbria and a paratubal cyst. (B) Histopathology of testicular tissue showing immature testicles containing immature germ cells and spermatagonia with decreased tubular diameter. Scattered groups of Leydig cells appearing immature. (C) Histopathology of hypoplastic uterine tissue removed demonstrating fragments of smooth muscle.

Figure 2 Sister 2. (A) Right gonad visualized at laparoscopy showing no Müllerian structures. (B) Histopathology revealed testicular tissue with benign Sertoli cell adenomas, entirely in the testicular parenchyma, consisting of relatively bland well-formed tubules lined by benign columnar cells. No evidence of spermatogenesis is seen in any of the structures. No malignant degeneration.
