临床观察与动物实验已支持这样一种假设:精子进入排卵前期的女生殖道,可能是宫颈癌的致病因素。动物实验发现,动情期(排卵前期)的宫颈上皮对癌的刺激特别敏感,精子可以穿透宫颈细胞,并与它们的核相融合,而引起宫颈上皮呈现细胞学及组织学上的异常。对雌性动物行实验性人工授精,可诱发 Clinical observations and animal experiments have supported the hypothesis that sperm entering the female genital tract of pre-ovulation may be a causative agent of cervical cancer. Animal experiments found that the estrus (preovulatory) of the cervical epithelium is particularly sensitive to cancer stimulation, sperm cells can penetrate the cervix, and their nuclear fusion, resulting in cervical epithelial cells showed cytological and histological abnormalities. Experimental artificial insemination of female animals can be induced
