RESUMEN
Background: Adenomyosis is a gynaecological condition characterized by the infiltration of endometrial glands and stroma resulting in ectopic intramyometrial, leading to the generalized enlargement of the uterus. Various cyclical regimens are employed globally to assist infertile women with adenomyosis during in-vitro fertilization (IVF) treatment because there is no consensus regarding the best protocol for managing adenomyosis. Case: The authors reported two cases the administration of long IVF protocol in Adenomyosis with pregnancy outcome. In both cases examined were found that the levels of anti-Mullerian hormone (AMH) were below the 25th percentile. Nevertheless, in both of these cases, the number of oocytes successfully retrieved was more than 5, which may have been influenced by the use of GnRH agonists in previous cycles of long protocol. Both of them were diagnosed with intrauterine pregnancy after transfer embryo. Conclusion: Although there is currently no consensus on the most suitable protocol for adenomyosis cases, the application of a long protocol in both of the aforementioned cases has yielded positive IVF outcomes.
