Fine-needle aspiration cytology in azoospermic males

Bilateral testicular fine-needle aspiration cytology (FNAC) was performed in 100 males, including 10 controls with normal fertility and 90 infertile azoospermic males. The various seminiferous tubular cells were easily identified in smears. It was possible to give a cytological diagnosis in histologic terms by analysis of the combinations of various cell types. The cytohistologic correlation in 25 cases was nearly 100%. FNAC is particularly useful in cases of obstructive azoospermia, where mature spermatozoa are seen in smears.
