Obstet Gynecol:流产后什么时候才能再次尝试受孕?

妊娠20周都还没到就流产了,那么想继续怀孕是要一定要等3个月以后才能进行尝试吗?WHO建议的可是要等6个月呢。新研究表明,3个月内开始尝试怀孕的成功机会跟等待3个月以上才开始尝试受孕的机会相同。

以往的研究主要集中在流产后相隔多长时间才能受精卵植入等,而很少关注何时开始尝试受孕。因此研究者纳入了1228名18-40岁女性进行了研究。集中调查了1083名女性,超过99%的女性在妊娠20周内流产。所有女性都没有以下并发症:异位妊娠或胎儿组织发育异常。研究者对其随访6个月经周期。

研究数据显示,超过76%的参与者在流产后3个月内尝试受孕;与等待3个月以上才开始尝试的人群相比,3个月内开始尝试的人群成功受孕率更高(61% vs. 51%),活产率也更高(53% vs. 36%)。且流产3个月内开始尝试妊娠的女性中没有发现妊娠并发症风险的增高。

关于传统上建议的流产后等相当长一段时间在开始尝试受孕的观念,研究者们没有发现生理上的必要原因,不过夫妻双方可能需要时间治愈流产所带来的负面情绪。但如果夫妻双方已经做好尝试再次受孕的准备,是没有必要非得等待3个月或更长时间以后再开始尝试受孕。

Hum Reprod Update:CA125对先兆流产结局的预示作用高于HCG和孕酮

背景:先兆流产影响1/5的女性,它与情绪困扰有显著相关性。先兆流产的预后仍然不能确定,由此成为了医疗护理专业人员的一项挑战。过去几年已经研究出多种生物标志物以预测先兆流产的结局;然而,结果却十分矛盾。因此,研究人员构建了一项系统性回顾性meta分析,以研究生物标志物在预测先兆流产女性妊娠结局的诊断准确性。方法:这是一项系统回顾性meta分析的前瞻性研究,探究生物标志物预测孕龄在5-23周范围的女性
