Background: Due to the heterogeneous distribution of seminiferous tubules (STs) in patients with nonobstructive azoospermia (NOA), retrieving enough good quality spermatozoa for ICSI may require a complete testicular dissection. According to the only available study in this field, spermatozoa may be found in the testis surface in 34.2% of patients, while a deeper testicular dissection is able to provide spermatozoa for ICSI in 28% of those without spermatozoa in the testis surface.

Objectives: To determine whether the seminiferous tubules pattern and the histological categories could affect the sperm retrieval rate in patients with non-obstructive azoospermia undergoing salvage microdissection testicular sperm extraction after failed conventional testicular sperm extraction.
Materials And Methods: Seventy-nine patients undergoing unilateral or bilateral salvage microdissection testicular sperm extraction were evaluated.
