Table 1.
Medians and interquartile ranges (IQR 75°–25° centile) of semen parameters evaluated by light microscopy, sperm apoptosis, necrosis, immaturity, and fertility index evaluated by transmission electron microscopy in semen samples of 63 men divided into 4 groups (leukocytospermia, L; idiopathic infertility, I; varicocele, V; fertile men, F) according to their clinical condition. Statistics are also reported: *P < .05, **P < .01, ***P < .001
