什么是胚胎植入前基因檢測(cè)

1、什么是胚胎植入前基因檢測(cè)(PGT)植入前的基因測(cè)試可以篩查遺傳疾病和染色體異常，增加試管嬰兒患者成功懷孕的幾率，生一個(gè)健康的寶寶。為了增加懷孕和擁有一個(gè)沒(méi)有遺傳疾病和染色體疾病的健康嬰兒的幾率，愛(ài)G國(guó)際合作的生殖中心提供植入前基因測(cè)試，以配合 IVF治療。隨著父母年齡的 增長(zhǎng)，孩子患唐氏綜合癥或染色體異常等遺傳疾病導(dǎo)致流產(chǎn)的可能性會(huì)增加。另外，如果患者是遺傳疾病的攜帶者，那么有可能遺傳給孩子或者影響生育能 力。植入前基因檢測(cè)解決了這些挑戰(zhàn)，防止遺傳疾病和染色體異常的遺傳。原理:植入前基因檢測(cè)篩選能夠讓醫(yī)生選擇最健康的胚胎植入。傳統(tǒng)的體外受精會(huì)導(dǎo)致多胎妊娠，比如雙胞胎甚至三胞胎，而胚胎植入前的基
