(A) Bax, cytochrome C, and caspase-9 and -3 were upregulated, whereas Bcl-2 was downregulated in oligoasthenospermia model rats; these changes were partly abrogated in rats treated with QLPs. (B) Bax/Bcl-2 ratio was increased in the model group and decreased by QLP treatment. Results shown represent the mean ± SEM of three experiments. *P<0.05 vs. Control, **P<0.05 vs. Model, ***P<0.05 vs. Low-dose QLPs.
