RESUMO
We aimed to compare repeated LPP (luteal phase oestradiol LPP/GnRH antagonists protocol) treatment with different protocol results with poor ovarian response (POR) patients. Two hundred and ninety-three cycles with poor ovarian reserve who underwent LPP, microdose flare up protocol and antagonist protocol were included in the study. Of these, 38 patients were applied LPP in the first cycle and LPP in the second cycle. After the microdose or antagonist protocol applied in the first cycle, LPP was applied to 29 patients in the second cycle. There are 128 patients who received LPP only once and 31 patients who received microdose flare up only once. The clinical pregnancy rate was monitored higher in LPP application group in the second cycle than the patients who received only LPP and patients who received LPP after different protocols (p = .035). b-hCG positivity per embryo and clinical pregnancy rate were found to be significantly higher with the LPP application in the second protocol (p = .000, p = .001). Repeated LPP may be the first choice protocol for low ovarian reserve patients.
What is already known on this subject? There is no standard treatment protocol applied to patients with low ovarian reserve. In this patient group, the rate of lack of response to stimulation and cycle cancellation is high. Increasing FSH level in patients with poor ovarian reserve causes the formation of larger follicles by increasing the sensitisation of follicles in the late luteal phase.What do the results of this study add? Our study was conducted for the first time in the literature. We compared the results of second cycle LPP (luteal phase oestradiol LPP/GnRH antagonists protocol) application in patients with low ovarian reserve who resulted in failed IVF after commonly used LPP, microdose flare up protocol and antagonist protocols.What are the implications of these findings for clinical practice and/or further research? Luteal phase oestrogen LPP/GnRH antagonist may be the first choice in patients with poor ovarian reserve patients. In unsuccessful cases, the LPP protocol should be considered in the retreatment for the second time.
