Abstract:
T-2 toxin, an inevitable environmental pollutant, is the most toxic type A trichothecene mycotoxin. Reproductive disruption is a key adverse effect of T-2 toxin. Herein, this paper reviews the reproductive toxicity of T-2 toxin and its mechanisms in male and female members of different species. The reproductive toxicity of T-2 toxin is evidenced by decreased fertility, disrupted structures and functions of reproductive organs, and loss of gametogenesis in males and females. T-2 toxin disrupts the reproductive endocrine axis and inhibits reproductive hormone synthesis. Furthermore, exposure to T-2 toxin during pregnancy results in embryotoxicity and the abnormal development of offspring. We also summarize the research progress in counteracting the reproductive toxicity of T-2 toxin. This review provides information toward a comprehensive understanding of the reproductive toxicity mechanisms of T-2 toxin.
Insights
T-2 toxin, a toxic environmental pollutant, harms male and female reproduction by disrupting reproductive organs, hormones, and fertility. Research also explores ways to counteract its adverse effects.
Area of Science:
- Environmental Toxicology
- Reproductive Toxicology
- Mycotoxicology
Background:
- T-2 toxin is a highly toxic type A trichothecene mycotoxin and an environmental pollutant.
- Reproductive disruption is a significant adverse effect associated with T-2 toxin exposure.
- Understanding T-2 toxin's reproductive toxicity is crucial due to its prevalence.
Purpose of the Study:
- To review the reproductive toxicity of T-2 toxin across different species and sexes.
- To elucidate the mechanisms underlying T-2 toxin's adverse effects on reproduction.
- To summarize current research on counteracting T-2 toxin's reproductive harm.
Main Methods:
- Literature review of studies on T-2 toxin's reproductive effects.
- Analysis of data on fertility, reproductive organ function, and gametogenesis.
- Examination of endocrine disruption and developmental toxicity.
Main Results:
- T-2 toxin exposure leads to decreased fertility, damaged reproductive organs, and impaired gametogenesis in both males and females.
- It disrupts the reproductive endocrine axis and suppresses reproductive hormone synthesis.
- Prenatal exposure causes embryotoxicity and developmental abnormalities in offspring.
Conclusions:
- T-2 toxin poses a significant threat to reproductive health in various species.
- Its mechanisms involve endocrine disruption and direct toxicity to reproductive tissues.
- Further research into mitigation strategies is warranted to address T-2 toxin's reproductive impacts.

Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...
