The association between ovarian cancer risk and reproductive factors has been well established, and two main theories, incessant ovulation and gonadotropin stimulation, have been proposed to explain the mechanism. Recent studies using animal models of ovarian tumorigenesis, and analysis of ovarian tissues from prophylactic oophorectomies, suggest that depletion of ovarian follicles might underlie the epidemiological findings linking reproductive history and ovarian cancer risk.
卵巢癌风险与生殖因素之间的关联已得到充分证实,并且已经提出了两个主要理论,即持续排卵和促性腺激素刺激,来解释其机制。最近使用卵巢肿瘤发生动物模型的研究以及对预防性卵巢切除术的卵巢组织分析表明,卵巢卵泡的耗竭可能是将生殖史与卵巢癌风险联系起来的流行病学发现的基础。
