From Prenatal Exposure to Adult Sexual Dysfunction: The Impact of Plastic-Derived Endocrine Disruptors on Testosterone Homeostasis and Erectile Function
AI summary Read the abstract
Everyday plastics — found in food packaging, containers, and countless consumer products — contain chemicals that can interfere with hormone signaling, and this review pulls together existing research suggesting they may lower testosterone and contribute to erectile dysfunction. The disruption seems to start as early as the womb, potentially affecting how the male reproductive system develops, and continues into adulthood by damaging blood vessels, promoting inflammation, and altering metabolism. While more research is needed to confirm direct cause-and-effect in humans, this is a good reminder to minimize plastic exposure where possible, especially around food and drink.
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 of plastic-based EDCs on testosterone regulation and male reproductive health has been provided. The role of developmental programming, endocrine disruption, oxidative stress, epigenetics, and vascular dysfunction has been explored in detail. Moreover, the possible involvement of micro- and nanoplastics has also been reviewed. From the data that is currently available, there seems to be a physiologically plausible association between plastic-based contaminants, testosterone dysregulation, and adverse reproductive outcomes.

Impacto de los disruptores endocrinos derivados de plásticos en la regulación hormonal masculina: un análisis integral de la evidencia científica
AI summary Read the abstract
This literature review compiled recent studies on how phthalates, bisphenol A, and microplastics from plastic products disrupt male hormonal regulation, finding evidence for reduced testosterone, impaired testicular synthesis, and alterations in the hypothalamic-pituitary-gonadal axis. The review calls for greater attention to plastic-derived endocrine disruptors in male reproductive health research.
Micro- and nanoplastics as emerging disruptors of Leydig cell function: A systematic review of experimental evidence
AI summary Read the abstract
Tiny plastic particles from our environment have already been found in human testicles, and this review pulls together 19 lab studies looking at how these particles affect the cells that produce testosterone. The evidence so far shows these plastics can stress and damage these cells, potentially lowering testosterone production, though the studies are mostly in animals and cells rather than people, so more research is needed to confirm the risk to human fertility and hormone health.
The Threat of Micro-/Nanoplastics to Male Fertility: A Review of the Data and the Importance of Future Research
AI summary Read the abstract
This review synthesizes findings from 21 studies examining how micro- and nanoplastics and their associated endocrine-disrupting chemicals affect male reproductive health at the cellular level. Researchers found evidence of multiple toxicity mechanisms including damage to the blood-testis barrier, disruption of hormone signaling, oxidative stress, and structural damage to testicular tissues. The study notes that while these findings from cell and animal studies are concerning, translating the results to human health requires further research with realistic exposure conditions.

Researchers review growing evidence that microplastics and nanoplastics, now detected in human semen and testicular tissue, disrupt spermatogenesis and testosterone production through oxidative stress, endocrine-disrupting additives, and blood-testis barrier damage, while also linking these mechanisms to elevated prostate cancer risk.
Polystyrene nanoplastics exposure causes erectile dysfunction in rats
AI summary Read the abstract
Researchers exposed rats to polystyrene nanoplastics through oral ingestion for 28 days and found that the particles accumulated in penile tissue and impaired erectile function. The nanoplastics caused oxidative stress, inflammation, and damage to the smooth muscle and blood vessel lining in erectile tissue. The study suggests that nanoplastic exposure may represent a previously unrecognized risk factor for reproductive health issues.
