This systematic review comprehensively evaluated the published scientific literature on glyphosate's effects on reproductive health in both animals and humans. Following PRISMA guidelines, the authors identified and analyzed dozens of studies examining endpoints including fertility, hormone levels, reproductive organ development, pregnancy outcomes, and transgenerational effects.
The review concluded that there is substantial evidence linking glyphosate exposure to adverse reproductive outcomes. Animal studies consistently demonstrate effects on both male and female reproductive systems, while human epidemiological studies show associations with altered hormone levels, reduced fertility, and adverse pregnancy outcomes. The evidence is particularly strong for endocrine disruption.
The authors noted that transgenerational effects — reproductive harm passed from exposed parents to unexposed offspring — have been documented in animal studies, raising the alarming possibility that glyphosate exposure today could affect the fertility of future generations.
Key Findings
- •Substantial evidence links glyphosate to adverse reproductive outcomes in both animal and human studies.
- •Endocrine disruption is the most well-supported mechanism of reproductive harm.
- •Male reproductive effects include reduced sperm quality, altered testosterone, and testicular damage.
- •Female reproductive effects include hormone disruption, altered ovarian function, and adverse pregnancy outcomes.
- •Transgenerational effects have been documented, with reproductive harm potentially passed to unexposed future generations.
Methodology
Systematic literature review following PRISMA guidelines. Databases searched included PubMed, Scopus, and Web of Science using defined search terms. Studies were screened for relevance and quality using the Newcastle-Ottawa Scale for observational studies and the Cochrane Risk of Bias tool for experimental studies. Evidence was synthesized narratively and graded for strength.
Why This Matters for Families
This systematic review confirms that glyphosate poses a real threat to reproductive health. For families trying to conceive or planning future pregnancies, minimizing glyphosate exposure should be a priority. The transgenerational findings mean that the choices parents make today about chemical exposure could affect their grandchildren's fertility.
