Clinical study on the treatment of male infertility with Wuwei Fuzheng Yijing decoction based on microplastics: Study protocol for a randomized controlled trial
AI summary Read the abstract
This clinical trial protocol describes a study testing a traditional Chinese medicine treatment for male infertility, with a focus on reducing microplastic levels in semen. It aims to explore whether microplastics in reproductive fluids contribute to fertility problems and whether targeted treatment can help.
This study will provide evidence for the efficacy and safety of WWFZYJ in treating male infertility and reducing the content of MPs in semen, and further explore the effects of MPs on male fertility.

Repair mechanism of Yishen Tongluo formula on mouse sperm DNA fragmentation caused by polystyrene microplastics
AI summary Read the abstract
This study investigated a traditional Chinese medicine formula (Yishen Tongluo) for its potential to repair sperm DNA damage caused by polystyrene microplastics. Researchers found that the formula's protective mechanism may be associated with the PI3K/Akt signaling pathway and the protein SPARC. The study suggests a new direction for using traditional medicine approaches to address reproductive system injury linked to microplastic exposure.
Association of mixed exposure to microplastics with sperm dysfunction: a multi-site study in China
AI summary Read the abstract
In a study of 113 men across three regions in China, microplastics were detected in all semen and urine samples tested, with eight different plastic types identified. The presence of certain microplastics, particularly PTFE (Teflon), was associated with reduced sperm quality, suggesting that microplastic exposure may pose risks to male fertility.
Comment on “Polyethylene and Polyvinyl Chloride Nanoplastics in Human Follicular Fluid and Seminal Plasma: Impact on Fertilization and Sperm Quality”
AI summary Read the abstract
A recent study made headlines by claiming to find tiny plastic particles (from common plastics like PE and PVC) in reproductive fluids linked to fertility problems, but this new commentary pushes back on those findings. The authors point out significant flaws in how the original study was designed and interpreted, suggesting the link between plastics and fertility issues isn't as solid as reported. The takeaway: while microplastics in our bodies remain a valid health concern worth studying, we should be cautious about jumping to conclusions from any single study until the science is on firmer ground.
Increased seminal microplastic burden in men with varicocele: a controlled clinical study
AI summary Read the abstract
In a controlled clinical study, researchers compared seminal microplastic burdens between men with varicocele—a condition linked to male infertility—and healthy controls. Men with varicocele had significantly higher microplastic concentrations in their semen, suggesting that the compromised blood-testis barrier and increased oxidative stress associated with varicocele may facilitate microplastic accumulation in the male reproductive tract.
Recent advances in microplastics research: impacts on mammalian sperm and reproductive health
AI summary Read the abstract
This review consolidates evidence that microplastic exposure reduces sperm quality, disrupts spermatogenesis, and can pass toxic effects across generations in mammals, acting through inflammation, hormonal disruption, and oxidative stress. As microplastics increasingly accumulate in human reproductive organs, understanding these mechanisms is urgently important for addressing a potential contributor to declining male fertility worldwide.
