Objective: We objectively evaluated the testicular sperm cell morphology.
Methods: The spermatozoa head morphology was evaluated by image analysis as presented on testicular fine-needle aspiration cytology smears.
Results: 2,356 spermatozoa heads were classified into six groups, according to different morphology parameters.
Conclusions: This objective method of morphologic assessment of testicular spermatozoa provides an important tool for the evaluation of testicular spermatozoa and can serve as a guide for therapy in male infertility.
