植入前遗传学诊断及筛查咨询

随着分子生物学技术的飞速发展及其在生殖领域的应用，植入前遗传学诊断（PGD）、植入前遗传学筛查（PGS）的遗传咨询变得更加复杂。在PGD、PGS的遗传咨询中，医生应充分告知患者PGD、PGS的应用现状、利弊、可能的预后、技术缺陷与安全性问题。同时，经PGD、PGS成功妊娠的孕妇，仍需进行常规的产前诊断，这一点对于PGD、PGS的安全性至关重要。

Counseling of preimplantation genetic diagnosis and screening.

Abstract:With the rapid development of molecular biology and its application in the field of reproduction, genetic counseling before PGD /PGS has become more and more complex. In this process，couples should be provided with evidence-based information on the techniques and their implications,as well as the Pros and cons of PGD. Of course, possible outcomes ,technical defects and security issues of PGD and PGS should also be informed. Meanwhile, the successful pregnant women after PGD / PGS should still do routine prenatal diagnosis, which is essential to the security of PGD/PGS.
