RESULTS OF PERCUTANEOUS EPIDIDYMAL SPERM ASPIRATION AND INTRACYTOPLASMIC SPERM INJECTION IN 2 MAJOR GROUPS OF PATIENTS WITH OBSTRUCTIVE AZOOSPERMIA

Percutaneous epididymal sperm aspiration (PESA) and intracytoplasmic s perm injection (ICSI) were carried out in patients,vith congenital bil ateral absence of the vas deferens (CBAVD) and men with failed reversa l of vasectomy (FRV). PESA was successful in 55 out of 62 patients wit h CBAVD (89%) and in 57 out of 60 men with FRV (95%). The fertilizatio n rates after ICSI (53 and 55%), cleavage rates (70 and 76%) and pregn ancy rates (36 and 32%) did not differ significantly between the two r espective groups (CBAVD and FRV). PESA and ICSI are effective both in patients with CBAVD and in those with FRV.
