The Physiology of Reproduction – Quo vadis?

This review argues that reproductive physiology remains poorly understood at the systems level, with gamete production and gonadal hormone dynamics reflecting complex, redundant informational networks whose full quantitative and developmental dimensions — and vulnerability to environmental disruptors — are still largely uncharted.

Single-cell sequencing reveals the reproductive variations between primiparous and multiparous Hu ewes

Researchers used single-cell sequencing to compare reproductive differences between first-time and experienced mother Hu ewes. The study identified key differences in gene expression within granulosa cells, suggesting these cells play a critical role in determining reproductive capacity. Several specific genes were highlighted as important regulators of follicular development and overall fecundity in sheep.

199 Nanoplastics are incorporated by the bovine cumulus–oocyte complex and form a potential treat for oocyte competence

Nanoplastics were found to be taken up by bovine cumulus-oocyte complexes — the cellular unit surrounding an egg — raising concern that nanoplastic contamination of reproductive tissues could compromise egg quality and fertilisation. This conference abstract provides early experimental evidence linking nanoplastic exposure to oocyte competence, with implications for understanding plastic-related reproductive risks across mammals.

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.

Microplastics are present in women’s and cows’ follicular fluid and polystyrene microplastics compromise bovine oocyte function in vitro

Researchers detected microplastics in both women's and cows' follicular fluid for the first time, and showed that polystyrene microplastics impair bovine oocyte function in vitro, raising concern that environmental microplastic exposure may be contributing to declining reproductive health.

Transcriptome-wide m6A profiling reveals mRNA post-transcriptional modification of boar sperm during cryopreservation

Researchers mapped chemical modifications (m6A tags) on messenger RNA in boar sperm during freeze preservation for the first time, finding these epigenetic marks are linked to sperm motility and cell survival — offering new insight into why sperm quality declines during cryopreservation.

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.

Microplastics are present in women’s and cows’ follicular fluid and polystyrene microplastics compromise bovine oocyte function in vitro

Researchers detected microplastics in follicular fluid from both women and cows and showed that polystyrene microplastics disrupt oocyte development, providing the first evidence that microplastics can penetrate reproductive barriers and potentially contribute to the global decline in fertility.

Microplastics are present in women’s and cows’ follicular fluid and polystyrene microplastics compromise bovine oocyte function in vitro

Researchers detected microplastics in the follicular fluid of both women and cows, marking one of the first studies to find these particles in reproductive tissues. In laboratory tests, polystyrene microplastics impaired bovine egg cell function at concentrations comparable to what was found in the follicular fluid. The findings raise questions about whether microplastic exposure could be a contributing factor in the widespread declines in reproductive health observed in recent decades.

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.

Analyzing the toxicological effects of PET-MPs on male infertility: Insights from network toxicology, mendelian randomization, and transcriptomics

Using network toxicology, Mendelian randomisation, and transcriptomic analysis, researchers identified mechanisms by which PET microplastics may impair male fertility, linking shared gene targets to testicular oxidative stress, hormonal disruption, and spermatogenesis interference. The multi-evidence approach strengthens the case for a causal role of PET-MP exposure in male infertility.
