title: Histopathology of testis in acquired immune deficiency syndrome.
abstract: Histologic sections from the testes of 32 autopsied patients with acquired immune deficiency syndrome (AIDS) were examined. Almost invariably the testes displayed decreased spermatogenesis, and 20 of the 32 cases showed marked hypospermatogenesis with Sertoli cells predominantly lining the tubules. Although the seminiferous tubules were generally of normal size, the tunica propria at the periphery of the tubules was mildly to moderately thickened in 19 cases and markedly thickened in 10. The interstitial cells of Leydig were unaltered in most patients, with only 4 testes showing Leydig cell hyperplasia. The testicular blood vessels were slightly thickened in many patients, but 5 exhibited moderate to marked intimal proliferation with narrowing of the lumen. Mononuclear inflammatory infiltration of the testicular interstitium was slight in 11 cases, moderate in 6. Only 7 of the 28 AIDS patients with opportunistic infections had evidence of direct involvement of the testes by the infectious organisms. We concluded that the extragonadal endocrine balance of AIDS patients may be deranged due to the infectious process and so deserves clinical evaluation.
