Salmon and tuna may help increase male fertility

January 10, 2012 11:39

Feeling, um, down and out. A certain omega-3 fatty acid, which is present in marine fishes like salmon or tuna, can help.

The Omega-3 fatty acid plays a vital role in determining male fertility, a new study has revealed. A University of Illinois study reported that docosahexaenoic acid is necessary to construct the arch that turns a round, immature sperm cell into a pointy-headed super swimmer with an extra long tail.

"Normal sperm cells contain an arc-like structure called the acrosome that is critical in fertilization because it houses, organizes, and concentrates a variety of enzymes that sperm use to penetrate an egg,' said Manabu Nakamura, a U of I associate professor of biochemical and molecular nutrition.

The study shows for the first time that DHA is essential in fusing the building blocks of the acrosome together.
