Introduction: Assisted conception is an option for subfertile couples. Surgical sperm retrieval by testicular sperm aspiration and testicular sperm extraction are widely used safe techniques to yield sperm for intracytoplasmic sperm injection. Experience with these techniques is presented. Materials and Methods: A retrospective study of testicular sperm retrieval for assisted reproduction is presented. Testicular sperm aspiration is attempted on all azoospermic males with normal sexual characteristics. Testicular sperm extraction is attempted on consenting patients where aspiration has failed. Donor sperm injection is done to oocyte of a spouse on the failure of both techniques. Results: Sixty-six percent of males had adequate numbers and characters of viable spermatozoa on testicular sperm aspiration. Further 53.3% of patients where aspiration failed yielded spermatozoa on testicular sperm extraction. Thus overall 77.1 % of patients with azoospermia benefi tted from testicular sperm retrieval techniques. Conclusions: Testicular sperm aspiration is a technically easy, quick, safe, and cheap method of sperm retrieval. Testicular sperm extraction is a safe adjunct to aspiration with better yield.

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.
