News | Antioxidant supplementation shows potential to improve male fertility
A new study suggests that antioxidant supplementation (AS) offers significant benefits for several key measures of male fertility, including sperm motility, morphology, DNA damage, sperm concentration, and overall fertility rates. This systematic review provides a new perspective on the use of antioxidants to improve male infertility.
Oxidative stress and male infertility
Infertility is the inability to conceive after one year of unprotected intercourse. More than 80 million couples worldwide are affected by infertility, with male infertility accounting for 30%-50% of cases.
Many factors can cause male infertility, including varicocele, smoking, radiation exposure, nutritional deficiencies, excessive alcohol use, psychological stress, excessive exercise, spinal cord injury, and environmental pollution.
Oxidative stress occurs when the production and removal of reactive oxygen species (ROS) become imbalanced. It can damage sperm membranes and DNA integrity, reducing sperm motility and causing DNA fragmentation, which significantly lowers the likelihood of conception.
If sperm with damaged DNA is not repaired during fertilization, it may also cause genetic mutations in the embryo and affect fetal development.
Study findings: Effects of antioxidant supplementation
The study reviewed 50 publications on the effects of antioxidants on male infertility and found that antioxidant supplementation can significantly improve semen quality. Common antioxidants and doses included:
Vitamin C (500-1000 mg)
Vitamin E (400 mg)
Zinc (25-400 mg)
Coenzyme Q10 (100-300 mg)
Carnitine (500-1000 mg)
Lycopene (6-8 mg)
Folic acid (0.5 mg)
Selenium (200 mg)
N-acetylcysteine (600 mg)
Studies show that vitamins C and E work together to protect sperm DNA, improve intracytoplasmic sperm injection (ICSI) outcomes, and reduce DNA damage. Carnitine and its derivatives, such as acetyl-L-carnitine, may improve sperm motility, while zinc supplementation may counter oxidative stress and restore normal semen function.
Challenges and future directions
Although studies demonstrate the potential of antioxidant supplementation to improve male fertility, the complexity of infertility means that an ideal treatment regimen has not yet been established. Differences among studies and unknown baseline antioxidant levels also make precise, individualized treatment difficult.
Future research should identify the optimal antioxidant combinations and appropriate doses while also considering how external environmental factors affect treatment outcomes.
