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 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 کاملOutcome of intracytoplasmic sperm injection with testicular spermatozoa in obstructive and non-obstructive azoospermia.
From 1 August 1993 until 30 September 1994, 69 couples suffering from azoospermia underwent testicular sperm extraction and intracytoplasmic sperm injection. In 50 couples with obstructive azoospermia a total of 631 metaphase-II oocytes were injected after testicular sperm extraction yielding a 2-PN fertilization rate of 57%. In female patients <40 years of age an ongoing pregnancy rate per tra...
متن کاملSperm retrieval for obstructive azoospermia
Advances in the treatment of male infertility now routinely allow men with obstructive azoospermia to have fertility treatment without microsurgical reconstruction. A variety of methods for retrieving sperm from men with obstructive azoospermia have been described. The goals of sperm retrieval are to obtain the best quality sperm possible, to retrieve adequate numbers of sperm for immediate use...
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 ...
