Application of percutaneous epididymal sperm aspiration in azoospermia.
OBJECTIVE The present study introduces the application of percutaneous epididymal sperm aspiration (PESA) for diagnosis of obstructive azoospermia and non-obstructive azoospermia. PATIENTS AND METHODS 96 cases diagnosed with azoospermia were selected, standard methods were used to measure testicular volume, chemiluminescence was used to test serum sexual hormone levels, and No. 7 butterfly ne...
متن کاملPercutaneous 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 کاملStudies of percutaneous epididymal sperm aspiration (PESA) and intracytoplasmic sperm injection.
Four distinct studies were carried out using two data sets of percutaneous epididymal sperm aspiration (PESA) and intracytoplasmic sperm injection (ICSI) procedures performed from March 1993 to January 1997. In study A, an analysis of 181 ICSI treatment cycles following PESA revealed a successful epididymal sperm retrieval rate of 83%. It confirmed that PESA is an effective sperm retrieval meth...
متن کاملSperm analysis of the vas deferens fluid after a long interval of unilateral percutaneous epididymal sperm aspiration in vasectomized patients.
OBJECTIVES Evaluation of the presence of spermatozoa in vas deferens fluid after a long interval of unilateral and homolateral percutaneous epididymal sperm aspiration (PESA) in vasectomized men. When found, the spermatozoa were evaluated including concentration and motility, in order to verify the patency of the epididymal tubules. MATERIALS AND METHODS Four patients, numbered in a progressi...
متن کاملThe mini-micro-epididymal sperm aspiration for sperm retrieval: a study of urological outcomes.
Epididymal sperm aspiration and in-vitro fertilization (IVF) with intracytoplasmic sperm injection is an established treatment for obstructive azoospermia. Sperm aspiration is performed with either an incision or percutaneously. To control costs, minimize morbidity and retain the advantages of both approaches, we developed a mini-incision technique for epididymal aspiration and here report sper...
