Pesticide residue on food could affect sperm quality, says Harvard study

Analysis of semen from men at fertility clinic matched with questionnaire on consumption of fruit and vegetables

Eating fruit and vegetables containing pesticide residues could adversely affect men's fertility, leading to fewer and poorer quality sperm, a study suggests.

Research by Harvard University found that men who ate the greatest amount of fruit and vegetables with high levels of pesticide residue had a 49% lower sperm count and a 32% fewer normally formed sperm than those who consumed the least.
