Carnitine\u00a0<\/strong>is present in high concentrations in the epididymis, where it facilitates the storage and transport of sperm. It protects against oxidative damage by acting as a natural antioxidant, thereby improving sperm motility, concentration and morphology, while regulating hormone levels such as testosterone and luteinising hormone. Recent meta-analyses and trials confirm these effects: after 3 months of L-carnitine supplementation, progressive motility increased by 18-40%, normal morphology by 4-15%, and cumulative pregnancy rates by up to +22% compared to placebo, with particularly marked benefits in cases of severe oligoasthenozoospermia.\u00b9<\/p>\n
