More Tuna: More Vital Sperm

Omega 3 fatty acids found in tuna can help to restore the quality of semen. A recent study has shown that men with low fertility can benefit from consuming tuna on a regular basis.


Ninety males were tested in the research, each with a prior medical history of failed fertility treatments and the study lasted for a period of four years. Thirty sperm donors were also included for their optimal seminal quality.
The research conducted in the Assisted Reproduction Unit Quiron–Bilbao has concluded that consumption of docosahexaenoic acid (DHA) found in Omega 3 in tuna in doses of 800mg per day for ten weeks can have a positive impact on sperm quality. With this diet, men with low fertility were found capable of recuperating sperm vitality levels reaching similar levels to those of a sperm donor.
Andrologist, Carmen Anarte said: “sperm membranes contain high percentage of polyunsaturated fatty acids and a sperm membrane having less DHA than the one desired becomes rigid and less flexible, making it more difficult for the sperm to fertilize the egg.”
DHA is a fat type that is found in the group of Omega 3 acids that is often found in fish like tuna, salmon and mackerel. These polyunsaturated fats are usually related to good cardiovascular health. DHA is also found in the brain, retina and sperm membrane.
The fatty acid’s main benefits are related to the optimal development and functionality of the brain, along with improving vision and the conception process. It is thought therefore that DHA is necessary for the proper brain and eye development of the fetus.
Anatre presented the summary of the paper ‘Can exogenous supplementation with DHA modify the lipid composition of the sperm membrane and improve semen quality of infertile patients?’ at the XXXII National Congress of the Spanish Society of Gynecology and Obstetrics SEGO 2013, in Tenerife.
