Testicular fine needle aspiration cytology in male infertility

Objective: To compare the accuracy of testicular fine needle aspiration and biopsy for diagnostic and therapeutic purposes. Study Design: A comparison of testicular fine needle aspiration and biopsy was performed on 34 infertile men over a 2-year period. Results: Concordance of the 2 tests was evident in 88% of cases. In discordant cases fine needle aspiration yielded more than biopsy, considering the existence of secondary spermatocytes and spermatids. Charcot- Bottcher crystalloids were frequently seen in the cytoplasm of Sertoli cells in normal and abnormal spermatogenesis. Conclusion: Testicular fine needle aspiration is a simple and costeffective method of evaluating testicular pathology in male factor infertility. It may yield more diagnostic and therapeutic material than does biops
