Andrologia, 2019 The aim of this study was to investigate the predictive value of the parameters that might have an effect on the success of microscopic testicular sperm extraction (micro-TESE) in infertile patients with nonobstructive azoospermia (NOA). Between 2003 and 2014, 860 patients with NOA were retrospectively analysed. The effect of age, infertility duration,

Evaluation of sperm retrieval rate with bilateral testicular sperm extraction in infertile patients with azoospermia. [PDF]
Iran J Reprod Med, 2015 About 10% to 15% of infertile men have azoospermia, which could be obstructive or non-obstructive. Diagnostic biopsy from the testis and recently testicular sperm extraction (TESE) are the most precise investigations in these patients. Testicular biopsy can be done unilaterally or bilaterally.
