However, among women who did continue to a second IVF cycle, those who had at least a chemical pregnancy on the first cycle were more likely to have a live birth on the second attempt than those women who had failed prior to conception in the first cycle (34% success rate compared to 21%, respectively).en-USepidemiologycensoringIVFARTJournal Article2017-05-1320092017-12-0510.1016/j.fertnstert.2008.07.1732
