Table 2.
Medians and interquartile ranges (IQR 75°–25° centile) of isoprostanes (F2-IsoPs), cholesterol (CHOL), estradiol (E2), testosterone (TESTO), iron (Fe), ferritin (FERR), transferrin (TRSF), and triglycerides (TRG) assayed in semen samples of 63 men divided into 3 groups according to their clinical condition (leukocytospermia, L; idiopathic infertility, I; varicocele, V; fertile men, F). Statistics are also reported: *P < .05, ***P < .001
