#85 : Microdissection Testicular Sperm Extraction (Micro-Tese) in Men Non-Obstructive Azoospermia with Very Small Testicular Volume: A Case Series Report

Background and Aims: Testicular atrophy is a common clinical manifestation of NOA, with a rate of 79.1%. The results of sperm retrieval using the mTESE method in a special NOA for testicular atrophy with volume $\le$5ml are currently inconsistent. As a result, we present the results of sperm retrieval using the mTESE method to patient NOA, who has a bilateral testicular volume $\le$5ml.

Methods: A case series report of NOA with bilateral testicular volume $\le$5ml that indicated mTESE surgery to collect sperm at the assisted reproductive technology center of Tam Anh Ha Noi General Hospital between January 2022 and December 2022.

Results: Four of seven NOA patients (57.1%) had successful sperm retrieval using the mTESE method, with bilateral testicular volume $\le$5 ml and a mean FSH level of 40,5 ± 21,9 (24,1-87,6) mIU/mL. In which case, 3/4 of patients simply require surgery on the monolateral testicular is sufficient sperm.

Conclusions: Testicular atrophy does not appear to impair sperm retrieval results by the mTESE method, even the sperm retrieval rate tends to be higher in NOA patients with bilateral testicular volume $\le$ 5ml.
