Abstract
Objective
This study aimed to assess the value of measuring the tubule diameter during microdissection testicular sperm extraction (micro-TESE) in predicting outcomes in patients with Sertoli cell-only syndrome (SCOS).
Methods
Fifty-six consecutive patients with SCOS were included. Patients were classified into two groups on the basis of the diameter of seminiferous tubules measured against 5/0 surgical suture (≥100 µm or <100 µm).
Results
The sperm retrieval rate (SRR) in men with a tubule diameter ≥100 µm was significantly lower than that in those with <100 µm (3.1% vs. 25.0%). The SRR from the contralateral testis in men with a tubule diameter ≥100 µm was lower than that in those with <100 µm (0% vs. 14.3%). Men with a tubule diameter ≥100 µm had a significantly larger testis and lower follicle-stimulating hormone levels than did men with <100 µm (8.1 ± 2.4 vs. 5.3±1.8 mL, 19.9 ± 9.7 vs. 25.9 ± 7.1 mIU/mL, respectively).
Conclusions
The diameter of tubules is a useful predictor for a successful SRR in men with SCOS. Intraoperative assessment of homogeneous large tubules allows some men to perform a limited (superficial) contralateral micro-TESE after no spermatozoa are initially identified.
