In infertile men given 16mg of astaxanthin daily for three months noted reductions in serum Inhibin B (29%) and improvements in seminal reactive oxygen species content (to 25% of baseline) although no other sperm parameter such as count of morphology was affected. Pregnancy rates increased with supplementation relative to placebo, possibly related to significant improvements in sperm adherence to oocytes.Funding issues for this study:
