    ارزیابی تاثیر پروتکل تاخیری در درمان بیماران با پاسخ ضعیف تخمدان
    تاثیر پروتکل تاخیریانتاگونیست GnRH در درمان بیماران با پاسخ ضعیف تخمدان
    InterventionalClinical trial with control group, non-blind, randomized, phase 2 on 60 patients. Closed envelope randomization was used for randomization.
    Interventional clinical trial with control and parallel groups, non-blind, randomized, phase 2 was performed on 72 patients. Randomization was performed using random number table.

    کارآزمایی بالینی دارای گروه کنترل، با گروههای موازی، کور نشده، تصادفی شده، فاز 2 بر روی 72 بیمار. انجام شد. برای تصادفی سازی از جدول اعداد تصادفی استفاده گردید.
    The objective of this study is evaluating the effect of delayed start protocol in ovarian poor responders. Study population: Infertile women with poor ovarian response candidate for IVF. Study groups: Intervention and control groups. There are thirty women in intervention group and thirty in control group. This is a randomized not blinded trail, in one center, in phase 2 study. Setting and conduct: Ovarian poor responders after obtaining informed consent randomized into intervention and control groups.

    هدف از این مطالعه ارزیابی تاثیر پروتکل تاخیری در درمان بیماران با پاسخ ضعیف تخمدان می باشد. جمعیت مورد مطالعه بیماران نابارور با پاسخ ضعیف تخمدان به تحریک که کاندید لقاح ازمایشگاهی هستند می باشد. گروه های مطالعه: دو گروه مداخله و کنترل. حجم نمونه 60 بیمار، کور نشده، تصادفی شده به دو گروه و یک مطالعه تک مرکزی و فاز 2. نحوه انجام: بیماران ناباروری که پاسخ دهنده ضعیف تخمدان به تحریک باشند وارد مطالعه شده و پس از دادن رضایت نامه اگاهانه به صورت تصادفی در دو گروه قرار می گیرند.

    In the intervention group with delayed protocol: First, like the control group, estradiol valerate 4 mg daily for 10 days starts from the 20th day of the previous menstrual cycle, then 7 days of daily administration of gonadotropin-releasing hormone antagonist (0.25 mg cetrorelix acetate) begins. The ovaries are then stimulated with gonadotropins.

The ovaries are then stimulated with gonadotropins. In the control group ovarian stimulation was performed using standard GnRH protocol.
    در گروه مداخله با پروتوکل تاخیری: ابتدا مانند گروه کنترل از روز 20 سیکل قاعدگی قبلی قرص استرادیول والرات 4 میلی گرم روزانه به مدت 10 روز شروع می شود سپس 7 روز تجویز روزانه ی آنتاگونیست هورمون ازاد کننده گونادوتروپین، 0.25 میلی گرم سترورلیکس، شروع می شود. بعد از ان تحریک تخمدان با گونادوتروپین انجام می شود.

Inclusion criteria: Patient with Bologna criteria for ovarian poor responders Exclusion criteria: History of endocrine disorders, severe endometriosis, azoospermia.
Intervention groups
In the intervention group with delayed protocol: First, like the control group, estradiol valerate 4 mg daily for 10 days starts from the 20th day of the previous menstrual cycle, then 7 days of daily administration of gonadotropin-releasing hormone antagonist (0.25 mg cetrorelix acetate) begins. The ovaries are then stimulated with gonadotropins. In the control group ovarian stimulation was performed using standard GnRH protocol.
