TeSE (Testicular Sperm Extraction) in Azoospermic Patients: m-TeSE vs. l-TeSE

Objective: To compare surgical outcomes and sperm retrieval rates (SRR) between conventional microsurgical-assisted testicular sperm extraction (m-TeSE - Group A) and testicular sperm extraction performed with surgical loupes (l-TeSE - Group B) in adult males with non-obstructive azoospermia (NOA). A multicentric prospective randomized trial was conducted from March 2022. Adult males with NOA without genetic alterations who agreed to participate in the study and signed the required informed consent were enrolled. SRR, intra and post-operative complications (according to Clavien-Dindo classification), hormonal profile tchanges were considered as outcomes during the follow up period.
