Potential baseline differences between the regimens were adjusted by propensity score matching. Clinical and laboratory data, including the cumulative clinical pregnancy rate (CCPR) and cumulative live birth rate (CLBR), were compared.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Ovulation induction required significantly longer use of gonadotropins in the GnRH agonist group. However, the GnRH agonist group had a lower starting dose of gonadotropin (all\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.05).

CCPR and CLBR for the oocyte retrieval cycles of the antagonist and ultra\u2010long agonist protocols were similar. The ultra\u2010long agonist protocol resulted in more favorable implantation of fresh embryos and improved clinical outcomes of the fresh cycle.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This novel strategy could be appropriate for endometriosis patients who are temporarily unsuitable for fresh embryo transfer.
