ABSTRACT

La exposición perinatal a diversos contaminantes ambientales y a otros agentes químicos afecta en formairreversible la diferenciación y programación de diversos tipos celulares, alterando cualitativa y cuantitativamentesus receptores hormonales mediante el mecanismo del imprinting, afectando su función y determinando el desarrollo de diversas patologías más tarde en la vida. En el presente trabajo se describen los agentes más conspicuos que actúan por este mecanismo afectando de por vida la salud reproductiva y la sexualidad. La investigación de este mecanismo, la identificación de sus agentes inductores y el desarrollo de medidas legislativas y administrativas para minimizar el daño constituyen un desafío pendiente para mejorar la saludreproductiva de las futuras generaciones.


Perinatal exposure to various environmental pollutants and other chemical agents irreversibly affects thedifferentiation and programming of various cell-types. This process quantitatively and qualitatively alters their hormone receptors through the mechanism of imprinting, affecting their function and determining the development of various pathologies later in life. The present report describes the most conspicuous agents acting through this mechanism, affecting for life reproductive health and sexuality. The study in detail of this mechanism, the identification of imprinting-inducing agents and the development of legislative and administrative measures to minimize damage constitute a pending challenge to improve future generations reproductive health.
