Beyond apoptosis: evidence of other regulated cell death pathways in the ovary throughout development and life
This review explores different types of programmed cell death in the ovary beyond the well-known process of apoptosis, and their roles in ovarian development and function throughout a woman's life. While not focused on microplastics directly, these cell death pathways are important because emerging research shows that microplastic and nanoplastic exposure can trigger abnormal cell death in ovarian tissue. Understanding these pathways is key to assessing how environmental pollutants may affect female fertility.
Implications of environmental toxicants on ovarian follicles: how it can adversely affect the female fertility?
This review examines how environmental toxicants, including endocrine disrupting chemicals, heavy metals, agrochemicals, and chemicals used in plastic and cosmetic industries, can adversely affect female fertility. Researchers found that these substances can interfere with follicle development and lead to conditions like polycystic ovary syndrome, premature ovarian insufficiency, and meiotic defects. The study highlights the difficulty of isolating individual risk factors since multiple toxicants often share common pathways of reproductive harm.
Microplastics in ovarian function and ozone-based mitigation strategies: Emerging evidence and translational implications

Preventing ovarian aging: from redox-targeted strategies to extracellular vesicle-based therapies
This review paper summarizes research showing that ovarian aging (when a woman's ovaries stop working properly) can be sped up by things like smoking, unhealthy diets, chemicals in plastics, and tiny plastic particles we're exposed to every day. Scientists are studying treatments like antioxidants and special cell therapies that might help protect women's ovaries from this damage. This matters because healthier ovaries could help women maintain their fertility longer and reduce health problems related to hormone changes as they age.
Evaluation of Ovarian Histomorphology and Function Following Clomiphene Citrate and Human Chorionic Gonadotropin Administration in Wistar Rats
Researchers evaluated the effects of clomiphene citrate and human chorionic gonadotropin — two commonly used fertility drugs — on ovarian histomorphology and fertility parameters in female Wistar rats. Both drugs altered ovarian follicle development and hormonal profiles, with some groups showing improved ovulation rates alongside structural changes that warrant consideration in clinical use.

The findings point to the environment-gut-ovarian axis as a potential pathway through which micro- and nanoplastic exposure could contribute to reproductive health concerns.
Concerning influences of micro/nano plastics on female reproductive health: focusing on cellular and molecular pathways from animal models to human studies
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.
Size- and hydrophobicity-dependent accumulation of microplastics in follicular fluid is linked to impaired ovarian reserve in women undergoing medically assisted reproduction
Researchers measured microplastic concentrations in follicular fluid and blood from women undergoing fertility treatment and found that nearly all samples contained microplastics. Higher microplastic concentrations in follicular fluid were significantly associated with reduced oocyte yield and lower odds of pregnancy, with evidence suggesting that certain hydrophobic polymers selectively accumulate in the ovary.
Allantoin Derived From Dioscorea opposita Thunb Ameliorates Cyclophosphamide-Induced Premature Ovarian Failure in Female Rats by Attenuating Apoptosis, Autophagy and Pyroptosis
Researchers studied whether allantoin, a compound from a Chinese yam species, could protect female rats from ovarian damage caused by the chemotherapy drug cyclophosphamide. They found that allantoin treatment reduced ovarian cell death through multiple protective pathways and helped preserve ovarian function. While this study does not involve microplastics, it contributes to understanding how natural compounds may help protect reproductive health from toxic chemical exposures.
