Nutritionist Isabella Obert looked into the best diet for male fertility, specifically focussing on the quality of sperm. This is important considering one fifth of men have low sperm count i.e. fewer than 15 million sperm per millilitre of semen.
In general, good health and nutritional adequacy translates into good overall sexual health, but Obert has decided to look into some specifics including dark chocolate which naturally contains L-arginine (the same ingredient found in most good pre-workout supplements to support blood support flow).
Sperm are considered highly receptive to oxidative stress, this damages sperm reducing its overall quality. So one way to increase the sperms quality is to consume an array of vitamins and minerals from fruit and veg, as well as including the following specific foods…tomatoes, walnuts, pumpkin seeds, lentils blueberries, pomegranates, dark chocolate and plenty of water.
It was also recommended that couples should reduce their total caffeine intake when trying to conceive. According to research, although caffeine doesn’t appear to reduce the size or shape of sperm, it did prove problematic in couple’s ability to conceive during IVF. Also ‘diet drinks’ that are high in Aspartame are considered ‘risky’ when trying to conceive, so avoid these where possible.
