Studies 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 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 کاملRelationship of paternal age with outcome of percutaneous epididymal sperm aspiration and testicular sperm aspiration: intracytoplasmic sperm injection with obstructive azoospermia
Objective: The study aimed to compare intracytoplasmic sperm injection (ICSI) outcome of patients with epididymal sperm and testicular sperm in different paternal age with obstructive azoospermia. Methods: We retrospectively studied the records of 177 men with obstructive azoospermia who underwent sperm retrieval for ICSI. 71 cases were performed with testicular sperm aspiration (TESA), 106 cas...
متن کاملMicrosurgical vasovasostomy versus microsurgical epididymal sperm aspiration/testicular extraction of sperm combined with intracytoplasmic sperm injection. A cost-benefit analysis.
PURPOSE Vasovasostomy (VVS) represents the standard therapy of choice for the treatment of obstructive azoospermia following vasectomy. However, recently, intracytoplasmic sperm injection (ICSI) has been suggested by some to represent the solution for all cases of malefactor infertility regardless of its etiology based on its success rates. Therefore, we compared VVS to microsurgical epididymal...
متن کاملEfficacy of intracytoplasmic sperm injection using intentionally cryopreserved epididymal spermatozoa.
Microsurgical epididymal sperm aspiration was a great advance in the therapy of patients with non-reconstructable, obstructive azoospermia, most notably congenital bilateral absence of the vas deferens. Using conventional in-vitro fertilization, pregnancies were rarely achieved because the rate of oocyte fertilization was extremely poor. However, the use of retrieved spermatozoa in conjunction ...
