Nutrient supplementation: improving male fertility fourfold

Area of Science:

• Reproductive Medicine
• Andrology
• Nutritional Biochemistry

Background:

• Oxidative stress is a known factor contributing to impaired spermatogenesis and male infertility.
• A variety of antioxidants, including carnitine, vitamins C and E, selenium, and coenzyme Q10, have been investigated for their potential benefits.

Purpose of the Study:

• To evaluate the effectiveness of antioxidant supplementation in improving semen parameters and pregnancy rates in men.
• To assess the impact of antioxidants on live birth rates, especially in the context of assisted reproductive technologies.

Main Methods:

• Analysis of data from a recent Cochrane review.
• Examination of outcomes including pregnancy rates and live birth rates.
• Focus on men undergoing assisted reproduction.

Main Results:

• Men taking antioxidants showed a statistically significant increase in both live birth and pregnancy rates.
• For men undergoing assisted reproduction, antioxidant use was associated with an odds ratio of 4.18 for improved pregnancy rates and a 4.85-fold improvement in live birth rate.

Conclusions:

• Antioxidant supplementation demonstrates a positive impact on reproductive outcomes in men, notably improving pregnancy and live birth rates.
• Randomized, controlled clinical trials are essential to further validate the safety and efficacy of antioxidant use in managing male infertility.
