El efecto de los agroquímicos en la espermatogénesis

the occupational exposition to agrochemicals was related with sperm parameters linked with spermatogenesis. in 104 semen samples of patients with idiopatic infertility of the reproduction service of centenario hospital (rosario, argentina), sperm study and functional tests according to who (1999) have been carried out. two groups were formed: g1 (n=42) workers exposed to agrochemicals; g2 (n=62) men with no spermatogenic risk. the sperm concentration was determined in neubauer camera, the concentration of germinal cells and the sperm morphology were evaluated with papanicolaou. the results were: sperm concentration (spermatozoids 106/ml) g1: 21.1 ± 7.1; g2: 41.6 ± 9.2; morphology (% normal spermatozoids) g1: 5.2 ± 1.3; g2: 8.2 ± 3.6; and germinal cells 106/ml in g1: 0.91 ± 0.51; g2: 0.32 ± 0.21. the sperm concentration was lower in g1, major morphological changes and germinal cells in g1. this results show that the exposition to agrochemicals alters the spermatogenesis, it is a factor to consider in the male infertility.
