Sperm quality can be improved with a simple diet supplement containing a compound found in cooked tomatoes. Lycopene can be found in some fruits and vegetables, but the main source in the diet is from tomatoes. Lycopene is a pigment that gives tomatoes their red colour, but dietary Lycopene is poorly absorbed by the human body. People taking more tomatoes are having more lycopene in blood. Thus consumption of tomatoes protects sperm from DNA damage.
The improvement in morphology ( the size and shape of the sperm), is dramatic. Lycopene's beneficial action is due to its antioxidant action. Consequently it potentially inhibits the damage caused by oxidation of sperm which is a known cause of male fertility problems.
