摘要

Objective: To investigate the feasibility of obtaining mature spermatozoa for intracytoplasmic sperm injection (ICSI) by testicular fine needle aspiration (TEFNA) in men diagnosed non-obstructive azoospermia. Methods: TEFNA was performed in 121 patients with a mean of 15 punctures and aspirations from each testis with a #23 butterfly needle connected to a 20 mL syringe with an aspiration handle. Results: One hundred and twenty-one patients underwent 176 TEFNA cycles. Testicular sperm were recovered in 56.3 % (99/176) cycles from 57 % (69/121) of patients. The sperm recovery rate was 46.7 % (21/45) in patients with Sertoli cell-only syndrome, 45.7 % (16/35) in patients with maturation arrest, 96.1 % (25/26) in patients with hypospermatogenesis and 63.6 % (7/11) in patients of non-mosaic Klinefelter's syndrome as judged by testicular histology. No sperm were found in 3 cases with post-irradiation fibrosis and one, after resection and chemotherapy of unilateral testicular cancer. In 87 cycles of ICSI using
