Abstract

Two noncontact techniques based on the use of ultrashort laser pulses are presented for assisted reproductive technologies. The first creates a unique alphanumeric code on an embryo’s envelope to simplify its identification during the period of preimplantation development. The second ensures the embryo will start to hatch at a prescribed site via laser-assisted drilling of its shell at the early blastocyst stage, where the inner cell mass and trophectoderm cells can be distinguished clearly.

基于超短激光显微外科的辅助生殖技术新技术

摘要

提出了两种基于超短激光脉冲的非接触技术，用于辅助生殖技术。第一种在胚胎的包膜上创建唯一的字母数字代码，以简化其在植入前发育期间的识别。第二种方法确保胚在胚泡早期通过在壳上进行激光辅助钻孔而开始在指定的位置孵化，在那里可以清楚地区分内部细胞团和滋养层细胞。
