Probe sees link between semen quality, pesticides

Paris (AFP) - Higher levels of pesticide residue in fruit and vegetables are associated with lower quality of semen, according to a study published on Tuesday.Its authors said the research was only an early step in what should be a much wider investigation.In a first recommendation, they urged men not to stop eating fruit and veg, and pointed to organically-grown food, or food that is low in pesticides, as options for lowering any apparent risk.The US team analysed 338 semen samples from 155 men attending a fertility centre between 2007 and 2012.The volunteers were aged between 18 and 55, had not had a vasectomy, and were part of a couple planning to use their own eggs and sperm for fertility treatment.The men were asked to fill out a questionnaire about their diet, asking them how often, on average, they consumed portions of fruit and vegetables.These portions were then placed into categories of being low, moderate or high in pesticide residues, on the basis of US Department of Agriculture data.Peas, beans, grapefruit and onions, for instance, fell into the low category, whereas peppers, spinach, strawberries, apples and pears were in the high category.The data factored in whether the items had been peeled and washed before being eaten.Men who had the greatest consumption of high-category fruit and vegetables had a total sperm count of 86 million sperm per ejaculate.This was 49 percent less than men who ate the least.
