Western blotting analysis of sperm DJ-1 from control subjects (n = 9) and Chinese asthenozoospermia patients (n = 30). (A) DJ-1 expression detected by Western blotting. (B) Levels of DJ-1 were normalized against GAPDH and expressed as fold change relative to control subjects. ∗P<.05 by Student unpaired t test.

Quantitive ELISA analysis of DJ-1 levels in ejaculated spermatozoa. (A) Sperm DJ-1 concentration in control subjects (n = 58) and asthenozoospermia patients (n = 113). ∗P<.05 by Student unpaired t test. (B) Sperm DJ-1 levels in control subjects (n = 58), mild asthenozoospermia patients (n = 70), and moderate asthenozoospermia patients (n = 43). ∗P<.05; ∗∗P<.01; by analysis of variance with post hoc Bonferroni test.
