The Summary
This 8-week randomized placebo-controlled pilot trial evaluated the effects of daily creatine supplementation, with or without ubiquinol, on sperm quality in 15 normospermic and oligospermic men. Researchers analyzed semen parameters, sperm biochemics, and self-reported well-being. While overall improvements in concentration showed a non-significant trend, 60% of creatine-supplemented participants experienced improved sperm concentrations compared to just 20% in the control group. Notably, all oligospermic men taking creatine (with or without ubiquinol) showed improved sperm concentrations, and those in the co-supplementation group experienced a 35.8% increase in sperm creatine levels.
Why this is interesting
While creatine is famously used for muscle building, its impact on reproductive health has been poorly understood. This study is the first to suggest that dietary creatine—especially when paired with the antioxidant ubiquinol—might directly accumulate in sperm and improve low sperm counts. For men dealing with oligospermia (low sperm count), these preliminary findings offer a simple, potential dietary intervention to support fertility. Although the sample size is very small and larger trials are needed, it opens a promising new avenue for natural male reproductive support.
