Lycopene - a natural pigment that gives red fruits and vegetables their colour - is an antioxidant that protects against cell damage, and tomatoes contain plenty of it. In fact, it is estimated that tomatoes account for 80% of the lycopene in the US diet. Now, a new study suggests Lycopene may also help boost sperm quality. According to the research by a team at the University of Sheffield, healthy men who consumed the equivalent of two tablespoons of concentrated tomato puree each day were found to have better quality sperm. During the 12-week trial, 60 men were randomly selected to take 14mg of lactolycopene supplement each day. The reason a supplement was used is because the participants would have had to eat 2kg of tomatoes each day to obtain an equivalent dose of lycopene. The participants’ sperm was tested before, during and after the trial. While there was no difference in sperm concentration, the men who had been taking the lycopene had healthier and faster sperm. Encouraged by the results, the researchers now want to expand the trial to include more men and see if the findings are the same. Lycopene has also been previously linked to other health benefits, including a lowered risk of heart disease and certain cancers.
A new study suggests that eating nuts regularly can improve both a man’s sperm count and the quality of the sperm produced. Experts say the finding is significant given that sperm counts across the Western world are in decline, a reality that’s been attributed to pollution, smoking and diet. At present, around one in seven couples have difficulty getting pregnant and figures show that 40-50% of infertility cases are attributable to men. For the study, scientists randomly split 119 healthy men between the ages of 18 and 35 into two groups. One group had 60 grams (2oz) of nuts added to their normal diet each day, while the other continued to eat as they always had done. The group that had the nuts added to their diet were found to have improved sperm – 14% greater count, 4% better vitality, 6% better motility (movement) and 1% better morphology (shape and size) – all of which are considered by the World Health Organisation (WHO) to be measures of sperm quality. Dr Albert Salas-Huetos, from the Universitat Rovira i Virgili in Spain, who led the study, said: "Evidence is accumulating in the literature that healthy lifestyle changes such as following a healthy dietary pattern might help conception”. The results of the study were recently presented at the annual meeting of the European Society of Human Reproduction and Embryology in Barcelona.
