Registration Number
NCT04414761
Lead Sponsor
ShangHai Ji Ai Genetics & IVF Institute
Brief Summary

Progestin can inhibit the pituitary LH surge during ovarian stimulation and various studies show progestin-primed ovarian stimulation (PPOS) is effective in blocking the LH surge in IVF. More and more centers in China are using PPOS because this regimen appears simpler and cheaper.A randomized trial to compare the effectiveness of PPOS and GnRH antagonist protocol in IVF in terms of the live birth rate is urgently needed.

Trial objectives: To compare the live birth rate between the PPOS protocol and the antagonist protocol used for ovarian stimulation during IVF

Eligible women will be randomised into one of the two groups:

Antagonist group : Women will receive antagonist (Cetrorelix or Ganirelix 0.25mg) once subcutaneously daily from day 6 of ovarian stimulation till the day of the ovulation trigger.

PPOS group: Women will receive oral medroxyprogesterone 10 mg daily or duphaston 10mg bd daily from Day 3 till the day of ovulation trigger.

There will be no fresh transfer. Only one blastocyst will be allowed to replaced in the first FET and a maximum of two blastocysts will be replaced in the subsequent FET cycles.

The primary outcome is the live birth rate of the first frozen-thawed transfer cycle.
