Impacts of Microplastic Debris on the Reproductive Health and Gestational Period Variability in Orcinus orca: A Comprehensive Review
Summary
Researchers reviewed the impacts of microplastic debris on reproductive health and fertility in wildlife species, documenting how plastic particles and associated chemical additives can disrupt endocrine function, impair gonadal development, and reduce reproductive success. The findings raise concerns about parallel effects in humans.
This comprehensive review delves into the correlation between microplastic debris in planetary oceans and variations in the gestational period of orcas (Orcinus orca). Microplastics, defined as plastic particles smaller than 5mm, have become ubiquitous pollutants in marine environments, with the potential to affect a wide array of marine life forms. As apex predators, orcas are particularly vulnerable to the bioaccumulation of toxins associated with microplastics. This review synthesizes existing literature on microplastic pollution, orca biology, and reproductive health to explore potential impacts and correlations. The evidence suggests that microplastics may disrupt endocrine functions in orcas, potentially leading to variations in gestational periods, with significant implications for population dynamics and conservation efforts.

Threats of nano/microplastics to reproduction and offspring: Potential mechanisms and perspectives
This review summarized the evidence on how nano- and microplastics threaten reproduction and offspring health across multiple species, including fish, invertebrates, and mammals. The authors outlined potential mechanisms by which these plastic particles disrupt endocrine function, gonadal development, and embryonic development.
Reproductive toxicity of micro- and nanoplastics
This review summarizes existing research on how micro- and nanoplastics harm reproduction across many species, from marine invertebrates to mammals. The particles can cause oxidative stress and hormone disruption, leading to reduced fertility, abnormal embryo development, and toxic effects that pass to offspring. The findings raise concerns that human reproductive health could be similarly affected given our increasing exposure to these particles.
Reproductive toxicity and related mechanisms of micro(nano)plastics in terrestrial mammals: Review of current evidence.
This review of terrestrial mammal studies found that micro- and nanoplastics induce reproductive toxicity through oxidative stress, inflammation, endocrine disruption, and DNA damage, affecting both male and female fertility. In males, effects include blood-testis barrier disruption and impaired spermatogenesis, while females show compromised oocyte maturation, ovarian fibrosis, and diminished ovarian reserve, with particles also capable of crossing the maternal-fetal interface.
The emerging risk of microplastics and nanoplastics on the microstructure and function of reproductive organs in mammals: A systematic review of preclinical evidence
Preclinical evidence from 12 studies shows micro- and nanoplastics accumulate in mammalian gonads, causing dose-dependent damage including seminiferous degeneration, sperm malformation, reduced follicular growth, and impaired hormone levels through pro-oxidant and pro-inflammatory mechanisms.
