Glyphosate-based herbicide formulations and reproductive toxicity in animals.

Area of Science:

• Agricultural Science
• Toxicology
• Reproductive Biology

Background:

• Genetically engineered (GE) crops, particularly those with glyphosate tolerance, are widely adopted.
• Increased weed resistance to glyphosate-based herbicides (GBHs) has led to higher herbicide application rates.
• Elevated glyphosate residues are consequently found in animal feed.

Purpose of the Study:

• To review the known effects of glyphosate-based herbicides (GBHs) on animal reproductive health.
• To assess the potential risks posed by GBH residues in animal feed to reproductive health.
• To highlight emerging concerns regarding GBHs and animal agriculture.

Main Methods:

• Literature review of studies on glyphosate-based herbicides and animal reproduction.
• Analysis of research on the impact of glyphosate residues on reproductive parameters.
• Synthesis of findings on enzyme disruption, hormone alteration, tissue damage, and gametogenesis impairment.

Main Results:

• Glyphosate-based herbicides show potential for adverse effects on animal reproduction.
• Disruption of androgen synthesis enzymes and altered estrogen/testosterone levels are reported.
• Damage to reproductive tissues and impaired gametogenesis are potential consequences.

Conclusions:

• Glyphosate residues in animal feed may pose a significant risk to reproductive health in livestock.
• Further research is needed to fully understand the long-term reproductive implications of GBH exposure in animal agriculture.
• Concerns regarding the safety of GBHs warrant attention within the agricultural and veterinary communities.
