自然流产自然流产 凡妊娠不足28周、胎儿体重不足1000g而终止者称为流产。自然流产是指胎儿尚无生存能力，也未使用人工方法，由于某种原因胚胎或胎儿自动脱离母体排出的，其发生率占全部妊娠的15%左右。自然流产的原因较多，主要有以下方面：①遗传基因缺陷：早期自然流产时染色体异常的胚胎占相当比例，占50%～60%，染色体异常多为数目异常，其次为结构异常；②外界不良因素：如有害化学物质如有机汞和物理因素如放射性物质可直接或间接对胚胎或胎儿造成损害；③母体因素：如妊娠期患急性病，高热可引起宫缩，细菌毒素或病毒使胎儿死亡；孕妇严重贫血或心力衰竭可致胎儿缺氧，高血压可使胎盘发生梗死等均造成流产；生殖器官疾病如子宫畸形、盆腔肿瘤影响胎儿发育导致流产。宫颈内口松弛或宫颈深度裂伤，易导致胎膜破裂发生晚期流产。内分泌功能失调可影响胚胎发育如黄体功能不足，甲状腺功能亢进或低下，糖尿病等。妊娠期创伤可刺激宫缩等；④胎盘内分泌功能不足使妊娠难以继续；⑤免疫因素：胚胎及胎儿与母体间存在复杂而特殊的免疫学关系，这种关系使胚胎及胎儿不被排斥。若母儿双方免疫不适应则可引起母体对胎儿的排斥而致流产。
