Fine needle aspiration of the testis and correlation with testicular open biopsy.

The diagnostic value of cytologic examination of aspiration biopsy smears was compared with that of histologic examination of surgically removed biopsy specimens from 54 testes in 32 men with oligoazoospermia. In 47 testes (87.1%) a good correlation was found between the results of the two methods: 20 cases had normal testicular morphology, 10 cases had spermatogenic arrest, and 17 had only Sertoli cells. In the remaining seven cases there was a paucity of cells, not permitting a cytologic diagnosis. FNA of the testis is a reliable and simple method of evaluating male infertility.
