    Background and Objectives: The aim of this study was to compare the in vitro fertilization (IVF) outcomes of long gonadotropin-releasing hormone agonist (GnRH-a) and GnRH-antagonist (GnRH-ant) protocols in endometriosis patients who have undergone laparoscopic endometrioma resection surgery. To our knowledge, there is no study in the current literature that compares the effectiveness of long GnRH-a and GnRH-ant protocols in management of IVF cycles in endometriosis patients who underwent laparoscopic endometrioma resection surgery. Methods: Eighty-six patients with stage III to IV endometriosis who had undergone laparoscopic resection surgery for endometrioma were divided into 2 groups: those who had ovarian stimulation with a long GnRH-a protocol (n = 44), and those who had ovarian stimulation with a GnRHant protocol (n = 42). Results: The number of follicles on human chorionic gonadotropin injection day, duration of hyperstimulation, number of retrieved metaphase II oocytes, and total number of grade 1 embryos were statically significantly higher in the long GnRH-a protocol. There were no significant differences in positive beta-human chorionic gonadotropin pregnancy rates (25% vs 21.4%; P = .269) and ongoing pregnancy rates per patient (20.5% vs 19.1%; P = .302) between the 2 protocols. Conclusions: Long GnRH-a and GnRH-ant protocols both present similar IVF outcomes in patients with endometriosis who have undergone laparoscopic endometrioma resection surgery. A long GnRH-a protocol may lead to a higher number of embryos that can be cryopreserved, providing the possibility of additional embryo transfers without having to go through the process of ovarian stimulation again.
