From Prenatal Exposure to Adult Sexual Dysfunction: The Impact of Plastic-Derived Endocrine Disruptors on Testosterone Homeostasis and Erectile Function
Abstract
Bisphenols, phthalates, and other plastic-associated compounds are endocrine-disrupting chemicals (EDCs), common environmental contaminants that can disrupt hormonal homeostasis. Human exposure to such chemicals occurs mainly through food packaging, consumer goods, medical devices, and the environment, starting right from early development stages up to adulthood. These chemicals might cause damage to male reproductive systems as a result of being anti-androgens and estrogenic chemicals. However, the proper development of the male reproductive system requires well-regulated hormonal signaling pathways; hence, exposure to such compounds during the developmental stages poses a great risk. Environmental exposure to plastics during fetal development may influence the development of the testes, reduce the function of the Leydig cells, disrupt steroidogenesis, and produce epigenetic modifications, as documented through studies. This has been shown to increase the risk of developing reproductive disorders and reduce the production of testosterone. Therefore, one of the pathophysiological links between endocrine disruptor exposure and ED might be testosterone deficiency. Apart from disrupting testosterone production, the plastic-sourced EDCs could influence various physiological processes associated with erectile performance, such as those related to vasculature, inflammation, metabolism, and endocrinology. In this review, a comprehensive overview of the scientific data on the effect…
