Background Everyday, humans are exposed to a mixture of environmental chemicals some of which have endocrine and/or metabolism disrupting actions which may contribute to non-communicable diseases. The adverse health impacts of real-world chemical ex...

Environmental Toxicology and Pharmacology, 94, Article 103913. https://doi.org/10.1016/j.etap.2022.103913

Current declines in male reproductive health may, in part, be driven by anthropogenic environmental chemical (EC) exposure. Using a biosolids treated pasture (BTP) sheep model, this study examined the effects of gestational exposure to a translationa...

Ovine fetal testis stage-specific sensitivity to environmental chemical mixtures (2022)
Journal Article
Lea, R. G., Mandon-Pépin, B., Loup, B., Poumerol, E., Jouneau, L., Egbowon, B. F., …Sinclair, K. D. (2022). Ovine fetal testis stage-specific sensitivity to environmental chemical mixtures. Reproduction, 163(2), 119-131. https://doi.org/10.1530/REP-21-0235

Exposure of the fetal testis to numerous individual environmental chemicals (ECs) is frequently associated with dysregulated development, leading to impaired adult reproductive competence. However, 'real-life' exposure involves complex mixtures of EC... Read More about Ovine fetal testis stage-specific sensitivity to environmental chemical mixtures.

Radiographic assessment of the skeletons of Dolly and other clones finds no abnormal osteoarthritis (2017)
Journal Article

Our recent report detailing the health status of cloned sheep concluded that the animals had aged normally. This is in stark contrast to reports on Dolly (first animal cloned from adult cells) whose diagnoses of osteoarthritis (OA) at 5½ years of age...
