According to a new study, appearing in February 13th issue of Science Translational Medicine, a woman’s fertility declines after her mid-30s possibly because, as women age, their egg cells become riddled with DNA damage and die off because their DNA repair systems wear out. The scientists suspect that most ageing oocytes self-destruct because they have accumulated a dangerous type of DNA damage called double-stranded breaks. The study found older oocytes have more of this sort of damage than do younger ones, and are less able to fix DNA breaks due to their dwindling supply of repair molecules.

Dr. Susan Taymans, PhD, of the Fertility and Infertility Branch of the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), commented, “We all know that a woman’s fertility declines in her 40s. This study provides a molecular explanation for why that happens. Eventually, such insights might help us find ways to improve and extend a woman’s reproductive life.”(http://www.nih.gov/news/health/may2013/nichd-21.htm)
With this in mind, Yourwellness Magazine reported on a recent study, published in the journal PLOS One, which found that organic food boosts fertility. According to Yourwellness Magazine, “Researchers at Southern Methodist University, in Dallas, carried out a study on fruit flies that revealed the insects fed an organic diet had better general health. Why the flies eating organic food did better was not revealed by the study but the team believe their work is a step along the way to understanding the potential health benefits of organic food.”
Yourwellness Magazine explained that the researchers used fruit flies because these particular insects are often used in studies on human diseases such as Alzheimer’s, diabetes and cardiovascular disease. The study found that longevity and fertility increased in the flies fed on organic food while those flies also performed better in general health tests. Yourwellness Magazine notes that further study is now required into how organic food might achieve the same outcomes in humans.
