Temporal trends in declining sperm quality are documented
Research gap analysis derived from 3 biology papers in our local library.
The gap
Temporal trends in declining sperm quality are documented globally, but the specific contribution of ultra-processed food consumption to this trend needs further epidemiological investigation.
Evidence profile
Sourced from the future work and open questions and limitations of the source papers, classified as data gap, drawn from work published between 2022 and 2026, spanning 3 journals. Those papers have been cited 1 times in total.
