New US research shows that docosahexaenoic acid is essential to build a vital sperm-cell structure.
In the study, mice that lack a gene essential to synthesize docosahexaenoic acid (DHA) showed to be infertile due to low sperm count and motility (1). When DHA was introduced into the mice’s diet, fertility was completely restored. The researchers showed that DHA is necessary for the building blocks of the sperm’s ‘acrosome’ to fuse. The acrosome is an arc-like structure that develops over half of the sperm cell’s head that houses and organizes a variety of enzymes which sperm use to penetrate an egg.
The scientists commented that in addition to create healthy sperm, DHA further has numerous health functions. Because DHA is abundant in specific tissues, including the brain and the retina, as well as the testes, the study results could also impact research relating to brain function and vision. DHA deficiencies could play a role, for example, in the development of dementia.

The results of the recent, comprehensive Age-Related Disease Study 2 (AREDS2) failed to support the prevailing view that marine omega-3 fatty acids could have a protective role in preventing the onset and progression of age-related macular degeneration (ARMD). Professor Eric Souied, Head of the Department of Ophthalmology at both the Hôpital Intercommunal de Créteil and the Hôpital Henri Mondor in France, has carefully reviewed the study and found that the null results could be due to methodological differences between this and other recent studies. He thinks that the evidence from laboratory and other clinical studies still provides hope that omega-3 fatty acids could provide benefits in relation to ARMD.
