摘要
目的 研究生长激素(GH)预处理对整倍体的改善及妊娠结局的影响.方法 前瞻性分析行胚胎植入前染色体非整倍体检测(PGT-A)助孕的134例患者,其中30例行自身对照,104例行组间对照.根据是否添加GH分为GH预处理组和GH非预处理组,GH预处理为促性腺激素(Gn)启动前行4～6周的GH 2 U/d皮下注射,Gn启动日剂量加倍直至扳机日,GH非预处理为未用过GH处理.前次PGT-A周期失败后一年内再次行PGT-A时予GH预处理构成自身对照组.组间对照和自身对照分别比较各组间的基本情况、囊胚情况及助孕结局.结果 无论组间对照还是自身对照,GH预处理后的HCG日子宫内膜厚度、卵巢敏感指数(OSI)、获卵数、MII卵数、2PN数、2PN受精率、可利用卵母细胞率、活检囊胚数、整倍体囊胚数、整倍体囊胚率、至少一个整倍体率均明显增加,差异均有统计学意义(P＜0.05),GH预处理后的Gn总量、Gn天数、嵌合体囊胚数、嵌合体囊胚率无明显变化,差异均无统计学意义,GH预处理后的种植率、临床妊娠率均有提高,但差异均无统计学意义.结论 GH预处理可以明显增加行PGT-A患者的整倍体数和整倍体率,并有改善妊娠结局的趋势.
Abstract
Objective To investigate the effect of growth hormone(GH)pretreatment on the improvement of eu-ploid and pregnancy outcome.Methods A prospective analysis was conducted on 134 patients undergoing preim-plantation genetic testing for aneuploidy(PGT-A),among whom 30 patients were self-controlled and 104 patients were inter-group controlled.According to whether GH was added,the patients were divided into GH pretreatment group and GH non-pretreatment group.GH pretreatment included subcutaneous injection of GH 2U/day for 4-6 weeks before the start of gonadotropin(Gn),and the dose was doubled on the day of Gn until the trigger day.GH non-pretreatment meant no GH treatment,GH pretreatment was given when the previous PGT-A cycle failed within one year when the PGT-A was performed again,forming the self-control group.The basic situation,blastocyst situa-tion and pregnancy outcome were compared between the groups by inter-group and self-control.Results No matter in the group control or self-controlled group,the endometrial thickness on the day of HCG,ovarian sensitivity index(OSI),number of oocytes obtained,MII oocytes,2PN number,2PN fertilization rate,available oocyte rate,num-ber of biopsy blastocysts,number of euploid blastocysts,euploid blastocyst rate,and at least one euploid rate sig-nificantly increased after GH pretreatment,with statistically significant differences(P＜0.05).The total amount of Gn,Gn days,number of mosaic blastocysts,and mosaic blastocyst rate were not significantly changed after GH pretreatment,with no statistically significant differences.The implantation rate and clinical pregnancy rate in-creased after GH pretreatment,but with no statistically significant differences.Conclusion GH pretreatment can significantly improve the number and rate of euploid embryos in patients undergoing PGT-A,and has a tendency to improve pregnancy outcome.
