- Abstract: OBJECTIVE: To investigate the effects of GnRH agonist and antagonist protocols on preimplantation genetic testing outcomes of chromosomal translocation carriers.METHODS: The clinical data of 226 patients with chromosomal translocation were analyzed retrospectively between Jan. 2015 and Dec. 2017 in Shengjing Hospital Affiliated to China Medical University.The patients were divided into GnRH agonist group(174 cases)and GnRH antagonist group(52 cases),then the duration of gonadotropin stimulation,dosage of gonadotropin used,embryonic quality,normal and balanced embryo numbers,per transfer cyclepregnancy rate,abortion rate and continuous pregnancy rate and accumulated pregnancy rate were analyzed.RESULTS: There were no statistical differences in the number of retrieved oocytes,number of MⅡ oocytes,fertilization rate,cleavage rate,blastocyst formation rate,number of high-quality embryo,number of blastocyst biopsy,normal and balanced embryo numbers,per transfer cycle pregnancy rate,abortion rate,continuous pregnancy rate or accumulated pregnancy rate between GnRH agonist group and GnRH antagonist group(P>0.05).The duration of gonadotropin stimulation(9 d vs. 10 d)and dosage of gonadotropin(2100 U vs. 2400 U)used in the GnRH antagonist group were significantly less than the GnRH agonist group(P<0.05).CONCLUSION: There are no significant differences in embryo quality or pregnancy rate between the GnRH agonist group and antagonist group during preimplantation genetic testing,but the GnRH antagonist group have an advantage in Gn duration and dosage.
