Red raspberries contain high concentrations of folic acid and vitamin C, which may have a positive effect on both male and female fertility, according to Medical Daily. Raspberry promotes healthy embryo development, for example, and increases the strength of sperm DNA in some men.
Folic acid is a B vitamin found in high levels in raspberries, notes Medical Daily. This vitamin is particularly important for women, as it helps regulate the development of unborn babies. Consuming sufficient amounts of folic acid before and during a pregnancy helps the production of new cells and can decrease the risk of birth defects in the baby's brain and spine, according to Medline Plus. Folic acid also lowers the baby's chances of being born underweight or premature and lessens the risk of miscarriage.
The aging process in men tends to damage or weaken sperm cells, but a study conducted by the U.S. Department of Energy’s Lawrence Berkley National Laboratory concluded that in men 44 or older, high levels of vitamin C consumption helped reduce DNA damage in sperm cells, and younger men who consumed sufficient vitamin C had up to 20 percent less sperm damage than those who did not, Medical Daily reports.
Antioxidants such as vitamin C help protect important genetic materials such as sperm and eggs, and they are a fundamental part of good fertility nutrition.
