Presence of PRDX5 and PRDX6 on the sperm surface and within the entire sperm cell. Bar charts depict fluorescence intensity of fluorescently labeled anti-PRDX5 antibodies in non-permeabilized (A) and permeabilized (B) sperm samples, as well as anti-PRDX6 antibodies in non-permeabilized (C) and permeabilized (D) sperm samples. Data are presented as the mean ± SD (n = 8 sperm samples). ***p < 0.001
