Study aim
-
To compare IVF results in patients with poor ovarian response included in the antagonist cycle recieving standard, double, and triple ovarian stimulation
-
Design
-
Three-arm parallel-group randomized clinical trial with 108 patients allocated into three groups, enrolled between April 2023- October 2023.
-
Settings and conduct
-
POR patients referred to the infertility department of Al-Zahra Educational Hospital, Tabriz, are assessed for eligibility to participate in the study. The eligible patients undergo controlled ovarian stimulation using antagonist protocol. After the diameter of the follicles reaches 16-18 mm, the randomization of patients into the study groups will be conducted by a nurse, using sealed envelopes, each containing a study group. Staff and patients will not be blinded. After 34- 36 hours, oocytes will be retrieved and evaluated by an embryologist. Following fertilization of the eggs and assessing embryo quality, embryo transfer will be performed and patients will undergo a pregnancy test (after two weeks) and vaginal ultrasound (after six weeks).

Intervention groups
-
POR patients are randomly divided into three groups: Group A, receiving human chorionic gonadotropin (hCG) (standard triggering), Group B, receiving hCG and decapeptide (as GnRHa) (dual triggering), and Group C, receiving hCG, Decapeptyl, and menotropin (hMG) (triple triggering).
