Objective To investigate the efficacy of intracytoplasmic sperm injection (ICSI) combined with percutaneous testicular sperm aspiration (PTSA)in the treatment of severe male infertility. Methods From October 1998 to December 2000, 162 couples were enrolled, and ICSI and PTSA were adopted. Ovarian stimulation was achieved by the short protocol. All metaphase Ⅱ (MⅡ) oocytes were selected for ICSI. Results 1 517 MⅡ oocytes were injected in 185 cycles, 990 fertilized (65.3%), and 152 embryo implanted. 54 couples achieved clinical pregnancy (35.5%). Conclusion PTSA combined with ICSI is a rapid, convenient, painless and effective approach for the treatment of severe male infertility.
