Comparison of oocyte count, fertilization, and pregnancy rates in adenomyosis patients undergoing In Vitro Fertilization with short and long protocol controlled ovarian stimulation - Restospective study.

Introduction: Adenomyosis (benign gynecological disease) is an endometrial stromal tissue condition that invades the myometrium of the uterus. The administration of a gonadotropin-releasing hormone (GnRH) analog before the IVF (In Vitro Fertilization) cycle significantly increases the chances of getting pregnant in adenomyosis patient with infertile condition. There is no best protocol consensus for adenomyosis for now. This study plans to compare the outcomes of long-protocol and short-protocol of IVF in adenomyosis patients who have undergone surgery and treatment with GnRH analogs. Method: This study is a retrospective study with a comparative method. The study was conducted at the IVF Aster Clinic and the IVF Bandung Fertility Center by reviewing retrospective data from 2015 to 2021. Patients who have been diagnosed with adenomyosis will undergo IVF procedure with a long-protocol and short-protocol pretreatment. Parameters observed were oocyte count, fertilization, and pregnancy rate. Results: Fifty-eight patients were included. There was a significant difference in the oocytes count and the pregnancy rate in short and long groups with p value of less than 0.05, while there was no significant difference in fertilization rate with p value of greater than 0.05. Conclusion: There were differences in the oocytes count and pregnancy rates in the short and long protocol groups in adenomyosis patients. There was no difference in fertilization rate in the short and long protocol groups in adenomyosis patients.
