Abstract
Objectives: This study aimed to determine the role of pre-surgical markers in the prediction of sperm retrieval in infertile Vietnamese men with azoospermia. Patients and Methods:Retrospective descriptive analysis of 136 infertile men with azoospermia, examined from August 2014 to July 2018. Patients underwent stepwise surgical sperm retrieval via percutaneous epididymal sperm aspiration, testicular sperm aspiration then multiple testicular sperm extraction in up to 3 locations until sperm were detected. Factorswere analyzed to determine the prediction of sperm retrieval.Results: The overall success rate of sperm retrieval was 49.3% including 88.3% and 18.4% in the OA and NOA group, respectively. The results of sperm retrieval were significantly associated only with the OA and NOA group, not with endocrine test or testicular volume. We found no significant difference in the endocrine test and testicular volume’s result between successful and unsuccessful sperm retrieval in either group.Conclusions: Neither an endocrine test nor testicular volume should be used for predicting the results of surgical sperm retrieval in infertile Vietnamese males with azoospermia.
