Comparison of relative expression levels of various SLC7A11-AS1 isoforms in spermatozoa of individuals with varicocele with those of fertile men. (A) Schematic representation from eight isoforms of SLC7A11-AS1. Five primer pairs (I–V) were used for evaluation of expression in spermatozoa samples (primers were indicated by arrows; qPCR-amplified products were indicated by red boxes). (B) Quantitative RT-PCR analysis of the expression of SLC7A11-AS1 isoforms using five primer pairs in the ejaculated spermatozoa of varicocele and control groups. Glyceraldehyde 3-phosphate dehydrogenase (GAPDH) was used for expression normalization. *P < 0.05 and ***p < 0.001 using independent sample t-test.
