To gain more insight of the most appropriate treatment protocol for infertile women with adenomyosis, we conducted this study comparing the pregnancy outcomes in infertile women with ultrasound-diagnosed adenomyosis in two treatment protocols, one is GnRH antagonist protocol with freeze-all strategy, the other is long-acting GnRH agonist protocol with fresh embryo transfer. The gene discussed is GNRH1; the disease is adenomyosis.
