本页汇总 大豆异黄酮 的 7 篇安全性公开文献，按毒性终点分区，逐条标注研究类型、物种、染毒途径与来源。以上均为各原研究/评估机构的结论，本平台不作再评价，也不构成对该成分的安全性判定。
NLC制剂在临床研究中未引起显著皮肤刺激，表明大豆异黄酮成分Orobol在该制剂中无刺激风险
The NLC formulation did not cause significant skin irritation in clinical study, indicating no irritation risk for the soy isoflavone orobol in this formulation.
孕期暴露于双酚A（BPA）和大豆异黄酮（SIF）的联合作用加重了雄性后代的生殖毒性（体重增加、睾丸病变、激素水平改变），但单独SIF组未报告显著效应。暴露途径为口服（饲料），非外用。
Co-exposure to BPA and SIFs exacerbated reproductive toxicity in male offspring (increased body weight, testicular lesions, hormonal changes), but SIFs alone were not reported to have significant effects. Exposure was oral (diet), not topical.
围产期暴露于大豆异黄酮诱导大鼠间质细胞增殖，增加间质细胞数量，并提高成年期血清和睾丸睾酮浓度。但该效应可能为适应性改变，未明确显示有害。暴露途径为膳食（口服）。
Perinatal exposure to isoflavones induced Leydig cell proliferation, increased cell numbers, and elevated serum and testicular testosterone in adulthood. However, this may be an adaptive change, not clearly adverse. Exposure was dietary (oral).
围产期暴露于高剂量大豆异黄酮（1000 ppm）导致成年雄性大鼠血清睾酮升高，但个体间质细胞类固醇生成减少；低剂量无显著效应。暴露途径为膳食（口服），非外用。
Perinatal exposure to high-dose isoflavones (1000 ppm) increased serum testosterone in adult male rats, but decreased steroidogenesis in individual Leydig cells; low doses had no effect. Exposure was dietary (oral), not topical.
成年雄性大鼠长期膳食暴露于大豆异黄酮（200或2000 mg/kg饲料）12个月，未观察到生殖毒性，精子参数正常。
Chronic dietary exposure to isoflavones (200 or 2000 mg/kg diet) for 12 months in adult male rats showed no reproductive toxicity; sperm parameters were normal.
综述认为，作为膳食成分的大豆异黄酮在通常摄入量下是安全的，未发现生殖发育毒性风险。
The review concludes that isoflavones as typically consumed in soy-based diets are safe, with no evidence of reproductive or developmental toxicity.
动物实验显示大豆异黄酮有雌激素活性和甲状腺过氧化物酶抑制作用，但体内甲状腺功能指标正常，需碘缺乏等额外因素才致甲状腺毒性；对人类生殖发育风险证据有限且矛盾。
Animal studies show estrogenic activity and TPO inhibition, but in vivo thyroid function normal; overt toxicity requires additional factors like iodine deficiency; evidence for human reproductive risk is limited and conflicting.
毒理学实验记录来自标准化的毒性试验（如 OECD 导则试验），给出的是剂量/浓度层面的实验值；公开文献是研究者围绕化妆品实际使用场景发表的研究（本页 7 篇），结论均为原作者观点。两类证据并列呈现，本平台不做合并判定。
