reported that the consumption of unsaturated fatty acids improved sperm antioxidant capacity of infertile men. However, some studies report no effect of fish oil on sperm quality. Fish oil (rich in n-3 PUFA) has been shown to alter sperm structure and penetration resistance, and to increase sperm number and antioxidant capacity. The few studies published to-date regarding the effects of PUFA on human and animal male reproduction have reported divergent findings.


In fact, researchers have discovered that the male sperm quality can be affected by the pathway of PUFA metabolism, oxidative stress, hormone levels, and physiological function of the epididymis. Intake of different types and sources of polyunsaturated fatty acids (PUFA) has been shown to change the fatty acid composition of animal sperm and affect sperm quality. Previous reports have revealed that the fatty acid content of spermatozoa in bulls, boars, rabbits, and humans are very high and has a unique function.
