【摘要】：目的探討女性年齡對胚胎植入前遺傳學(xué)診斷及篩查(PGD/PGS)結(jié)局的影響。方法回顧性分析2015年1月1日至12月31日開展PGD/PGS治療周期的149例患者,按女性年齡將患者分為3組:Ⅰ組10例(25歲)共36枚囊胚;Ⅱ組94例(25~34歲)共329枚囊胚;Ⅲ組45例(≥35歲)共89枚囊胚。比較各組之間的胚胎正常率和臨床妊娠率。結(jié)果Ⅰ組、Ⅱ組、Ⅲ組的胚胎正常率分別為50.00%、50.15%、29.21%。Ⅰ組與Ⅲ組的胚胎正常率比較差異有統(tǒng)計學(xué)意義(χ~2=4.855,P0.05),Ⅱ組與Ⅲ組的胚胎正常率比較差異有統(tǒng)計學(xué)意義(χ~2=12.376,P0.05)。Ⅰ組、Ⅱ組、Ⅲ組的臨床妊娠率分別為83.33%、82.50%、40.00%。Ⅰ組與Ⅲ組的臨床妊娠率比較差異有統(tǒng)計學(xué)意義(χ~2=3.893,P0.05),Ⅱ組與Ⅲ組的臨床妊娠率比較差異有統(tǒng)計學(xué)意義(χ~2=7.510,P0.05)。結(jié)論女性年齡對PGD/PGS結(jié)局有影響,當(dāng)女性年齡≥35歲時會明顯降低胚胎的正常率和臨床妊娠率。
