冷冻卵子

冷冻卵子

冻卵即冷冻卵子,是指把采集的卵子在一种特殊溶液中迅速冰冻,然后用液氮保存起来,这项技术本来是为了造福先天不育或失去生育能力的女性,但现在许多因为事业而选择晚婚晚育的女性也选择冷冻卵子.

生殖科医生称,44岁以上的女性受孕率相对较低,25岁-30岁的女性成功率最高。随着女性年龄的增长,受孕率会逐步降低.而冷冻卵子可以将卵子保存在当时的年龄,等到需要的时候可在试管婴儿技术的帮助下受孕.

2012年11月18日,45岁的阿根廷女子莫尼卡利用自己33岁时冷冻的两枚卵子和丈夫的精子.生下一对双胞胎女儿.创造了利用储存时间最长的冷冻卵子产子的世界纪录.

冻卵不仅能延长女性的生育期限,也可以让由于身患癌症而可能丧失生育能力的女性在进行放疗或化疗或卵巢切除术之前保存她们的卵母细胞,为更多的人实现生育的需求.
