Rating (out of 5): 3

Fatty acids, especially omega-3 polyunsaturated fatty acids (such as EPA and DHA), are scientifically investigated for their roles in supporting male reproductive health. Research indicates that fatty acids are crucial structural components of sperm cell membranes, influencing sperm motility, morphology, and overall fertility. Several clinical and animal studies have shown that supplementation with omega-3 fatty acids can improve semen quality, particularly sperm concentration and motility. For example, a 2019 randomized controlled trial published in Andrology found that omega-3 supplementation led to a significant increase in total sperm count and motility in infertile men.

Fatty acids also exhibit anti-inflammatory properties and play a role in hormone production, both of which are relevant to male reproductive function. However, the magnitude of the effect and the optimal dosage remain subjects of ongoing research, and not all studies have shown significant benefits. While the evidence is promising and mechanistically plausible, it is not universally conclusive, thus meriting a moderate evidence rating.

In summary, the use of fatty acids, particularly omega-3s, to support the male reproductive system is supported by a moderate amount of scientific research, primarily based on improvements in semen parameters and potential benefits to hormonal balance and inflammation.
