| Popis: | Purpose: After intracytoplasmic sperm injection was established to facilitate in vitro fertilization in men with the most severe semen abnormalities, the use of testicular sperm to achieve conception became feasible. We investigated the use of a method of percutaneous needle aspiration previously used for diagnostic purposes to obtain testicular sperm for intracytoplasmic sperm injection.Materials and Methods: A method of percutaneous aspiration of sperm was developed to facilitate intracytoplasmic sperm injection. A total of 69 testicular aspirations were performed for diagnostic purposes and 179 to obtain sperm on the day of egg retrieval for couples undergoing in vitro fertilization with intracytoplasmic sperm injection. The procedures were performed in an outpatient facility. Most patients received intravenous sedation and a few received only local anesthesia.Results: Sperm adequate for intracytoplasmic sperm injection were obtained in all men with obstructive azoospermia, including those with... |
