    "name": "Dysplastic testis",
    "definition": "A descriptive term denoting a developmental anomaly of the male gonad characterized by architectural disorganization of the testicular parenchyma, which may include irregular or poorly formed seminiferous tubules, a thinned tunica albuginea, and increased or fibrotic interstitial tissue. Macroscopically, the testis may range from near-normal in size and appearance to a small, firm, or streak-like structure.",
