Popis: | To evaluate the effect of double stimulations during the follicular and luteal phases in women with poor ovarian response (POR) in in-vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) cycles.This prospective clinical study was performed in Royan Institute from October 2014 to January 2016. 121 patients were diagnosed as POR on the basis of Bologna criteria were included. Double stimulations were performed during the follicular and luteal phases by Letrozole, Clomid, hMG and GnRH-agonist. The patients' present cycle outcomes were compared with those of the previous cycle results using appropriate statistical tests.The total of 104 (85.9%) patients completed the stimulation stages. The analysis revealed the number of retrieved oocytes after the first and second stimulations did not differ (P = 0.2); however, the fertilization rate and the number of frozen embryos after the first stimulation were significantly higher than those of in the second stimulation (P 0.001 and P = 0.03), indicating the better quality of retrieved oocytes after the first stimulation. The mean number of MII oocytes and the fertilization rate after Shanghai protocol were higher than those of the previous antagonist protocol with a substantial trend toward significance (P = 0.06), which can be clinically important. The cancellation rate (33%) due to no ovarian response and no embryo formation was still high in these patients.Since the intensity of stimulation in both stages was mild, this protocol can be considered a time-efficient and patient friendly regime; however, more studies are required with emphasis on its cost-effectiveness. |
