From: Appropriate cut-off value for follicle-stimulating hormone in azoospermia to predict spermatogenesis
Depiction of ROC curves of serum FSH can discriminate between successful or failed sperm retrieval. Depiction of receiver operating characteristic (ROC) curves of serum follicle-stimulating hormone (FSH) can discriminate between successful or failed sperm retrieval. The area under the ROC curves was 0.939 ± 0.02 (with a 95% confidence interval for the area being between 0.891 and 0.986). A FSH cut-off point of 13.7 mIU/mL discriminated between groups A and B with a sensitivity of 85.7% and a specificity of 87.0%. When the cut-off point was increased to 19.4 mIU/mL, the sensitivity of FSH level was 70% and the specificity was 100%. Arrows indicate the cut-off point for serum FSH 19.4 mIU/mL.
