Ezeh, N. Taub, H. Moore, I. In order to predict the probability of retrieving at least one testicular spermatozoon we conducted a prospective study of a set of variables in 40 patients with non-obstructive azoospermia. Using the receiver operating characteristic curves, we determined the probability estimates of testicular volume, plasma follicle stimulating hormone FSH concentration, Johnsen score and visualization of testicular spermatids in discriminating between patients with successful and failed testicular sperm extraction.

Correspondence Address : Dr. We performed this meta-analysis to evaluate the predictive value of different parameters in the sperm retrieval rate SRR of microdissection testicular sperm extraction TESE in patients with nonobstructive azoospermia NOA. We chose three parameters to perform the meta-analysis: follicle-stimulating hormone FSH , testicular volume, and testicular histopathological findings which included three patterns: hypospermatogenesis HS , maturation arrest MA , and Sertoli-cell-only syndrome SCOS. If there was a threshold effect, only the area under the summary receiver operating characteristic curve AUSROC was calculated. Twenty-one articles were included in our study finally. The sensitivities of them were 0.

Sperm harvesting is entirely different from a diagnostic testicular biopsy because, in this setting, the goal is not to identify what is happening in the testis but instead it is to find sperm. Only men with no sperm in their ejaculate azoospermia need to have sperm retrieved directly from the testis or epididymis. This may involve a simple aspiration for men who have a blockage or require much more extensive sampling of the testis for men who have a sperm production problem.
