Impact of microplastics on female reproductive health: insights from animal and human experimental studies: a systematic review
AI summary Read the abstract
This systematic review of 15 experimental studies found that microplastic exposure significantly impairs ovarian function, decreases fertility rates, and disrupts hormone levels in female subjects. Several studies also reported negative effects on embryo development and offspring health, though study quality varied and more rigorous research is needed to confirm mechanisms.
OBJECTIVE: This systematic review aims to evaluate the impact of microplastics on female reproductive health by analyzing experimental studies. METHOD: A comprehensive search was conducted in PubMed, Web of Science, and Scopus databases to identify experimental studies published between 2021 and 2023. Studies investigating the effects of microplastics on reproductive organs, hormone levels, fertility rates, and offspring development in female subjects were included. The quality of the studies was assessed using the Cochrane risk of bias tool. RESULTS: A total of 15 studies met the inclusion criteria. The results indicate that exposure to microplastics significantly affects ovarian function, decreases fertility rates, and disrupts hormone levels in female subjects. Several studies also reported negative effects on embryo development and offsprings health. The quality of the studies varied, with some showing a high risk of bias. CONCLUSION: The evidence from experimental studies suggests that microplastics have a detrimental effect on female reproductive health. However, the variation in study quality highlights the need for more rigorous research to confirm these results and better understand the underlying mechanisms.

A review of the impact of micro‐ and nanoplastics on female reproduction: What we know and gaps in knowledge
AI summary Read the abstract
This review examines what is known about how micro- and nanoplastics affect female reproductive health. Animal studies show these particles accumulate in ovarian tissue, disrupt hormones, and cause oxidative stress, leading to hormonal imbalances and ovarian damage, though research in humans is still limited.

AI summary Read the abstract
This systematic review examined evidence linking microplastic exposure to reproductive health problems in humans. While early findings raise concerns, the review emphasizes that more high-quality studies are needed to clearly establish how microplastics affect fertility and reproduction.
Concerning influences of micro/nano plastics on female reproductive health: focusing on cellular and molecular pathways from animal models to human studies
AI summary Read the abstract
This review summarizes research showing that micro- and nanoplastics can harm the female reproductive system in multiple ways, from reducing ovarian reserves and disrupting hormone balance to accumulating in the placenta and breast milk. Animal studies show these particles trigger oxidative stress and inflammation in reproductive tissues, and human studies have confirmed their presence in placental tissue and infant feces, raising concerns about effects on fertility and fetal development.
Effects of micro(nano)plastics on the reproductive system: A review
AI summary Read the abstract
This review summarizes research on how micro and nanoplastics affect the reproductive system in both animal studies and cell experiments. Evidence indicates these particles can cross biological barriers, accumulate in reproductive organs, and disrupt hormones, egg development, and sperm quality. While human studies are still limited, the animal data suggests microplastic exposure may be a meaningful concern for reproductive health.
