Intervention model description: Randomized multi-center controlled trial comparing 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) in terms of surgical outcomes and sperm retrieval rates
Primary purpose: TREATMENT

Brief summary: The aim of the study is to compare surgical outcomes (intra and post-operative complications) and sperm retrieval rates 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.

Detailed description: 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.

Eligibility criteria: Inclusion Criteria:

* Adult males
* Diagnosis of non obstructive azoospermia who required m-TeSE.

Exclusion Criteria:

* Absence of signed written informed consent
* Age \< 18 years
* Obstructive azoospermia
* Genetic anomalies (e.g., Klinefelter syndrome, Kallmann syndrome, Y chromosome microdeletions, CFTR mutations)
* Previous testicular biopsies/surgical sperm retrieval
* Personal history of malignant testicular tumor
* Unilateral cryptorchidism
* Varicocele
* Previous chemotherapy/radiotherapy treatments
* Monorchidism
