Mixed Gonadal Dysgenesia vs. Cryptorchidism

Left picture: In fact, the catheterized opening corresponds to a vagina and at surgery a streak gonad, a fallopian tube and a uterus was found on the right side of the lower abdomen, and a vas deferens on the left side as can be seen in the fourth figure from top to bottom on the corresponding side. As the cause of the external (and internal) intersexual genitals a mixed gonadal dysgenesia was found which is caused by abnormal development of the gonads due to a chromosomal mosaic. Right picture: In this toddler a right-sided cryptorchidism is present, and more precisely, a prefascial ectopy of the testis (sliding testis). Notice the scrotal skin of the right scrotal pouch and the foreskin of the penis in comparison to the first contralateral picture from top to bottom, where no circumcision has been performed.

Left picture: 5-month-old boy with a full left and an empty scrotal pouch. Right picture: Toddler with a visible testis in the left scrotum; the right scrotal half is slack, small and empty. Left picture: Following a precise clinical examination, intersexual external genitals have to be considered; in contrast to the empty right labioscrotal fold, the left scrotal half exhibits distinct skin folds (so-called rugae) and a testis is visible and palpable, which can be recognized in in the third figure from top to bottom. At the lower surface of the penis a catheterized opening is visible in continuation of a groove (so-called verge enlisée), which reminds in the second figure from top to bottom of a severe type of hypospadias.
