    Abstract:
    OBJECTIVE: To evaluate percutaneous epididymal sperm aspiration (PESA) and testicular sperm extraction (TESE) in the diagnosis and treatment of azoospermia. METHODS: We examined 385 azoospermia patients using the techniques of PESA and TESE. RESULTS: Of the total number of the azoospermia patients, 64 (16.62%) had sperm in the epididymis and 45 (11.69%) in the testis. Intracytoplasmic sperm injection (ICSI) was applied to 64 of the patients with sperm in the epididymis or testis. The pregnancy rate after the embryo transfer was 39.07%. CONCLUSION: PESA and TESE, as an effective therapy for azoospermia, can further the classification of azoospermia and provide chances of procreation to azoospermia patients with partial obstruction.
