Over the time course of the scientists fed a group of lab rats 50 mg/kg chrysin (human equivalent ~8mg/kg) or placebo for 60 days and found:
that chrysin significantly increased GSH, CAT, GSH-Px and CuZn-SOD levels, but did not change the formation of TBARS significantly. In addition, sperm motility, sperm concentration and serum testosterone levels significantly increased, whereas abnormal sperm rate significantly decreased with chrysin treatment.In essence the improvement in antioxidant markers (vs. placebo) went hand in hand with a measurable increase in sperm health and serum testosterone.
