Quality assessment was carried out using the criteria outlined in the Cochrane Handbook for Systematic Reviews of Interventions. Egger test and funnel plot analysis were used for publication bias assessment. The primary outcome was clinical pregnancy rate (CPR). Secondary outcomes were live birth rate (LBR), pregnancy loss rate (PLR), and implantation rate (IR).<\/jats:p><\/jats:sec><jats:sec><jats:title>Main Results<\/jats:title><jats:p>Nine studies with 2087 women were included. Ultralong (3\u2009months GnRH agonist) (SUCRA 24.5%) and long protocols (1\u2009month GnRH agonist) (SUCRA 24.9%) as well as progestins (SUCRA 28.8%) showed similar results to no treatment (SUCRA 21.8%) in terms of post\u2010ART CPR. Regarding the LBR, no treatment (SUCRA 50.0%) showed highest rates relative to progestins (SUCRA 7.0%), and long (SUCRA 36.6%) and ultralong (SUCRA 6.4%) protocols. For PLR, no treatment (SUCRA 57.9%), followed by long protocol (SUCRA 18.4%), ultralong protocol (SUCRA 12.3%), and progestins (SUCRA 11.4%) showed the greatest degree of reduction.
