Peer-reviewed research concerning environmental exposure, summarized and appraised in plain language with every source cited.
This systematic review set out to examine how phthalates, chemicals widely used to soften plastics and to carry fragrance in cosmetics, affect male fertility by altering semen quality. It pulled…
This review set out to explore how environmental factors affect sperm quality and male fertility. It analyzed 82 recent studies, mostly from 2020 onward, looking at pollutants, heat, radiation, and…
This review set out to examine how microplastics (tiny plastic particles) affect the male reproductive system at the cellular and molecular level. It compiled findings from multiple studies across scientific…
This study asked which workplace exposures matter most for men's reproductive health. It took 80 men working in an automobile parts plant, measured their exposure to magnetic fields, electric fields,…
This study set out to see if microplastics (tiny plastic particles) are present in human semen and whether they might affect sperm health. Researchers analyzed semen samples from 45 men…
This study set out to see whether microplastics turn up in semen in ordinary men with no plastics job, and whether they track with sperm quality. Researchers took semen from…
This study set out to see whether microplastics in the body track with sperm quality. Researchers checked semen and urine from 113 men across three regions of China for eight…
This review set out to explore how polystyrene microplastics (PS-MPs) might harm male fertility by damaging the blood-testis barrier (BTB), a protective shield in the testicles that keeps harmful substances…
This study set out to clarify how bisphenol A (BPA, a chemical used in food packaging and container linings) affects men's reproductive health. It pooled 18 studies that measured BPA…
This systematic review and meta-analysis set out to find which lifestyle, environmental and health factors go with higher sperm DNA fragmentation, meaning breaks in the genetic material inside sperm, where…
This study set out to look at whether microplastics are present in human semen, a concern given animal studies suggesting they might harm reproductive health. Researchers analyzed semen samples from…
This meta-analysis set out to work out how high ambient temperature affects sperm quality. It pooled nine studies covering 356 men in Iran, Italy, Thailand, China and Egypt, comparing men…
This review set out to see whether sweating clears toxic metals from the body. It pooled 24 studies that measured arsenic, cadmium, lead and mercury in sweat, compared those levels…
