多囊卵巢综合征(PCOS)是最常见的女性内分泌疾病,根据种族和诊断标准的不同,患病率高达8%-15%。基本的病理生理学和遗传模式尚不清楚,但环境因素,如饮食,压力和化学暴露被认为是促成因素。发育过程中暴露于内分泌干扰物(EDCs)被认为会加剧风险,部分原因是围产期雄激素暴露可以可靠地在动物模型中诱导PCOS特征和相关的代谢共病。在这里,我们表明,终生暴露于含有内分泌活性植物雌激素的大豆饮食中,但不暴露于内分泌干扰单体双酚A(BPA)的发育中(妊娠第6天-哺乳期第40天),可以诱导大鼠多囊卵巢综合征的关键特征;这一结果支持了这样的假设,即在整个妊娠和出生后生活中食用激素活性饮食可能会增加风险。
Polycystic ovarian syndrome (PCOS) is the most common female endocrine disorder with a prevalence as high as 8–15% depending on ethnicity and the diagnostic criteria employed. The basic pathophysiology and mode of inheritance remain unclear, but environmental factors such as diet, stress and chemical exposures are thought to be contributory. Developmental exposure to endocrine disrupting compounds (EDCs) have been hypothesized to exacerbate risk, in part because PCOS hallmarks and associated metabolic co-morbidities can be reliably induced in animal models by perinatal androgen exposure. Here we show that lifetime exposure to a soy diet, containing endocrine active phytoestrogens, but not developmental exposure (gestational day 6 – lactational day 40) to the endocrine disrupting monomer Bisphenol A (BPA), can induce key features of PCOS in the rat; results which support the hypothesis that hormonally active diets may contribute to risk when consumed throughout gestation and post-natal life.
