Percutaneous epididymal sperm aspiration (PESA) in men with obstructive azoospermia.
OBJECTIVES Assessing the efficiency of repeated percutaneous epididymal sperm aspiration (PESA) in men with obstructive azoospermia, and also the possibility of cryopreservation of remaining material for future use in intracytoplasmic sperm injection (ICSI). METHOD Retrospective study, in which 79 procedures of PESA were assessed in 58 patients (mean age = 45 years), whose partners had mean a...
متن کاملEvaluation of sperm retrieval rate with bilateral testicular sperm extraction in infertile patients with azoospermia
BACKGROUND About 10% to 15% of infertile men have azoospermia, which could be obstructive or non-obstructive. Diagnostic biopsy from the testis and recently testicular sperm extraction (TESE) are the most precise investigations in these patients. Testicular biopsy can be done unilaterally or bilaterally. The worth of unilateral or bilateral testicular biopsy in men with azoospermia is controver...

متن کاملExtended sperm preparation: an alternative to testicular sperm extraction in non-obstructive azoospermia.
Testicular sperm retrieval for the treatment of non-obstructive azoospermia requires the execution of an invasive procedure, with all its possible attending complications and subsequent long-term effects. This study suggests a new non-invasive approach for collection of spermatozoa in these patients: the extended sperm preparation (ESP). ESP consists of conducting a thorough microscopic search ...
متن کاملComparison of efficacy of two techniques for testicular sperm retrieval in nonobstructive azoospermia: multifocal testicular sperm extraction versus multifocal testicular sperm aspiration.
To compare the efficacy of 2 sperm-retrieval procedures, testicular sperm extraction (TESE) and testicular sperm aspiration (TESA), during the same procedure using the same subjects as their own controls. The presence of mature testicular sperm cells and motility were evaluated in 87 men with nonobstructive azoospermia (NOA) by means of multifocal TESE and multifocal TESA, which were performed ...
