    "name": "Vanishing testis",
    "definition": "A condition which is considered to be due to the subsequent atrophy and disappearance in fetal life of an initially normal testis. In the presence of spermatic cord structures is evidence of the presence of the testis in early intrauterine life. When associated with a blind-ending spermatic cord, this entity is named as his absence of a testis in an otherwise normal 46XY male is usually unilateral and is assumed to be a consequence of intrauterine or perinatal torsion or infarction.",
