Fetuses and children are more susceptible to the effects of environmental toxins. The objective of this article is to determine the levels of organochlorine pesticides (HCB, ß-HCH, pp'DDT, op'DDT and pp'DDE) in the serum lipids of mothers of newborns with cryptorchidism and compare the levels to a control group of mothers of newborns with descended testicles. The cases were composed of newborns with cryptorchidism (n=41), and the controls (n=41) newborns with descended testicles. Blood samples from both groups of mothers were used to determine the organochlorine pesticide levels. Cryptorchidism was diagnosed at birth by a neonatologist. The results showed that the organochlorine pesticide residues were found in the serum lipids of both groups of mothers. The median serum lipid levels (mgkg-1 lipid-based) were statistically higher for the metabolites pp'DDT (0.464 vs. 0.269) and ß-HCH (0.263 vs. 0.192) in the cryptorchidism group compared to the control group (p<0.01). It could be concluded that the levels of the metabolites pp'DDT and ß-HCH are higher among mothers of newborns with cryptorchidism. It is possible that substances with anti-androgenic effects could produce endocrine disruption, such as cryptorchidism, during fetal development.
