Studies conducted in the Assisted Reproduction Unit Quiron-Bilbao show that the consumption of omega 3 fatty acids can help restore the quality of semen.
According to Carmen Anarte, an andrologist, the contribution of exogenous supplementation based on microalgae oil, which is rich in docosahexaenoic acid (DHA) and in doses reaching 800 mg/day for 10 weeks, makes it possible for infertile men to reach levels of morphology and sperm vitality that are similar to those of a sperm donor, who is required to have a very high level of semen quality.
Anarte presented a summary of his thesis in the XXXII National Congress of the Spanish Society of Gynecology and Obstetrics SEGO 2013, held in Tenerife in May.
The paper is titled Can exogenous supplementation with DHA modify the lipid composition of the sperm membrane and improve semen quality of infertile patients?
The research lasted four years and involved 90 males with a prior medical history of failed fertility treatments, and 30 sperm donors, chosen for their optimal seminal quality Hospital Group Quiron reported.
According to Anarte, "sperm membranes contain a 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."
The DHA is a type of fat that is beneficial for the body, which belongs to the group of omega- 3 polyunsaturated fats that are usually associated with cardiovascular health.
The DHA is also found in the sperm membrane, in the retina and in the brain.
It is a fatty acid able to concentrate on various body structures and the distribution makes it possible to foresee that its main benefits are related to the optimal development and functioning of the brain, with visual acuity and with the conception process.
That is to say, the DHA is necessary for the proper brain and eye development of the fetus.
