Ubiquinol and Male Fertility
Oligozoospermia (also called oligospermia) refers to a low sperm concentration and is a common contributor to male infertility. It is often accompanied by abnormalities in sperm motility (movement) and morphology (structure).
Emerging research suggests that ubiquinol, the reduced and biologically active form of coenzyme Q10 (CoQ10), may support sperm health. In a double-blind, placebo-controlled trial published in the Journal of Urology (June 13, 2012), researchers evaluated ubiquinol supplementation in 228 men with unexplained infertility and oligozoospermia.
Participants were randomly assigned to receive 200 mg of ubiquinol daily or placebo for 26 weeks, followed by a 12-week observation period. Men receiving ubiquinol experienced significant improvements in sperm density, motility, and morphology compared with placebo.
These findings suggest that supporting mitochondrial energy production and antioxidant status—both key roles of CoQ10—may be relevant in certain cases of male infertility.
