Objective:To evaluate the improvement of pereutaneous epididymal sperm aspiration(PESA)and testicular sperm extraction(TESE) and the therapy value in the diagnosis and treatment of azoospermia. Methods:We examined 218 azoospermia patients by the techniques of PESA and TESE.Results:Of the total number of the azoospermia patients
94(43.12%)had sperm in the epididymis and 28(12.84%)in the testis.Intracytoplasmic sperm injection (ICSI) was applied to 16 patients with sperm in the epididymis or testis after sperm extraction.The pregnancy rate after the embryo transfer was 37.5%. Conclusion:The improvement of the PESA and TESE can provide safer chances of procreation to azoospermia patients with partial obstruction and effective therapies for azoospermia.
