Oogenesis02:07

Oogenesis

In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...

主要方法:

  • 一项回顾性研究,比较了在卵细胞检索时接受子宫内膜理 (活检) 的女性与没有理的对照组.
  • 关键的终点包括流产,临床妊娠率 (CPR),持续妊娠率 (OPR),活产率和慢性子宫内膜炎 (CE) 的发生率.

主要成果:

  • 在和对照组之间,在总怀孕率,CPR或OPR中没有发现显著差异.
  • 慢性子宫内膜炎 (CE) 的发病率在划伤组为10.8%.
  • 在接受子宫内膜划痕的组中,注意到第二个三个月的损失风险明显更高.

结论:

  • 在冷幼胚胎移植之前的子宫内膜痕并没有改善妊娠结果.
  • 这种程序与第二个三个月妊娠流产的可能性增加有关.
  • 慢性子宫内膜炎 (CE) 是在卵细胞检索时接受子宫内膜划伤的患者的常见发现.
