Abstract

To study the long-term impact of neonatal exposure to endocrine-active compounds (EACs) on plasma lipid profiles, steroid concentrations, and morphology of porcine luteal tissue, piglets were injected with testosterone propionate (TP), flutamide (FLU), 4-tert-octylphenol, ICI 182,780 (ICI), methoxychlor, or corn oil (controls) between postnatal days 1 and 10 (n = 5/group). Blood samples and corpora lutea were obtained from sexually mature gilts. The investigated compounds differentially affected plasma lipid and steroid concentrations. Moreover, we demonstrated hypertrophy of luteal cells after neonatal EAC administration. In addition, a predominant abundance of lipid droplets was found in luteal cells of TP-, FLU-, and ICI-treated animals. It seems that the pathways leading to changes in the plasma lipid profile may contribute to the development of long-term alterations that have the potential to affect luteal steroidogenic capability in pigs.
