La exposición a plaguicidas se asocia con la disminución del recuento espermático

Out of the total of 224 serum samples available, at least one pesticide was quantified per sample, with an average of 11 pesticides per sample; the most frequent being p,p'-DDE, present in 95.98% of the samples. Only in the case of endosulfan sulphate (present in 45.1% of the volunteers) was there a strong reduction tendency in the number of spermatozoa of more than 1.23 million, reaching statistical significance(P=0.009), with a 95% confidence interval of −1.43 to −1.05. As far as the number of motile spermatozoa were concerned, it was also only with endosulfan sulphate that a statistically significant reduction of 1.23 million (P=0.02) in the total number appeared, with a 95% confidence interval of −1.47 to −1.04).
