چکیده

Background: Recently different studies suggested that discontinuation of gonadotrophin releasing hormone analogue (GnRHa) at beginning of ovarianstimulation (improvement of ovarian response to gonadotrophins) may have some benefit to poor responder patients in invitro fertilization (IVF) cycles.Objective:The efficacy of GnRHa stop protocol in poor responder patients in IVF cycles was assessed. Materials and Methods: This study was a prospective, randomized controlled trial that40 poor responder patients (less than three mature follicles in a previous cycle) with normal basal follicle stimulating hormone (FSH) were randomly allocated into two protocols: 1) Non-stop protocol: long GnRHa suppression, and start gonadotrophins from day 3 of mense. 2) Stop-protocol: GnRHa is stopped with the onset of menses, and gonadotrophin doses remained similar to group 1.Results: A significantly higher number of follicles, oocytes, embryos and fertilization rate also shorter stimulation days and lower human menopausal gonadotropins (HMG)ampoules were recorded in the stop protocol compared to the control group. Both protocols resulted in a similar cancellation rate, pregnancy rate, estradiol level and LHlevel. Conclusion: Early follicular cessation of GnRHa permitted the retrieval of a significantly higher number of follicles, oocytes and embryos, and can reduce the number of HMG and stimulation days.
