INTRODUCTION Prenatal exposure to some pesticides can adversely affect male reproductive health in animals. We investigated a possible human association between maternal exposure to 27 organochlorine compounds used as pesticides and cryptorchidism among male children. DESIGN Within a prospective birth cohort, we performed a case-control study; 62 milk samples from mothers of cryptorchid boys ...

Concern that the reproductive health of humans is being affected by exposure to xenoestrogens has led to the development of various in vitro and in vivo screening assays for the identification of suspected xenoestrogens. However, the estrogenic activity of a chemical determined in vitro may not necessarily predict its activity in vivo if the chemical is metabolized during the assay and/or in vi...

This study used an MCF-7 cell based ER-alpha reporter gene assay to assess chemical interactions within the following ternary mixtures: (1) three synthetic pesticides, methoxychlor (MXC), o,p-DDT, and dieldrin; (2) three polyaromatic hydrocarbons, benzo[a]pyrene (BAP), 1,2-benzanthracene (BENZ), and chrysene (CHRY); and (3) an endogenous estrogen, [17beta-estradiol, (E(2))]; a phytoestrogen, ge...

Persistent organochlorine residues in the environment are a threat to ecological health of aquatic organisms and pose risk both animals human consumers. Organochlorine pesticides were determined water sediments collected during wet dry season from selected riverine earthen fish pond sites high altitude catchment areas within Kuja River (Kenya) between August 2016–May, 2017. Analysis DDT metabol...

2 SUMMARY The major protocol features of the immature rat uterotrophic assay have been evaluated using a range of reference chemicals. The protocol variables considered include the selection of the test species and route of chemical administration, the age of the test animals, the maintenance diet used and the specificity of the assay for estrogens. It is concluded that three daily oral DGPLQLV...
