Sperm quality influenced by diet

Sperm quality is influenced by diet, according to a new study by researchers at Linkoping University. A group of 15 normal, non-smoking healthy men were given a healthy diet for two weeks. In the third week, sugar was added in the form of confectionery and fizzy drinks.  It was found that sperm motility had increased in patients who were diagnosed with low sperm motility at the beginning of the study. The researchers also found that the small RNA fragments, which are linked to sperm motility, also changed. They are now planning to continue the work and investigate whether there is a link between male fertility and the RNA fragments in sperm. They will also determine whether the RNA code can be used for new diagnostic methods to measure sperm quality during in vitro fertilisation.
