However, the LBR using a freeze-all strategy in IVF is unknown.STUDY DESIGN SIZE AND DURATIONThis retrospective cohort study included 20 687 women who started their first IVF cycles using a freeze-all strategy during the period from 1 January 2007, through 31 March 2016, in China.PARTICIPANTS /MATERIALS, SETTING, METHODSData on 20 687 women undergoing their first complete cycles using a freeze-all strategy from 2007 to 2016 were analyzed to estimate LBRs. The LBR in a complete cycle was defined as the chance of a live birth from an ovarian stimulation cycle including all subsequent frozen embryo transfers from this stimulation. The relationship between LBR and number of oocyte was explored.MAIN RESULTS AND THE ROLE OF CHANCEThe LBR for the first complete cycle was 50.74% for patients using a freeze-all strategy. By age group, the LBR declined from 63.81% for w...
