  • Protocol summary

    This study is a prospective randomized study(Randomized numbers' table).the aim of this study is evaluation of effect of GnRH-a in endometrial preparation for frozen-thawed embryo transfer cycles in patient with repeated implantation failure.inclusion criteria:infertile womem(18-42) who are candidate for frozen-thawed embryo transfer; with at least 2 previous failed implantation.Eexclusion criteria :oocyte donation;intrauterine lesion;history of less than 2 previous failed implantation. at first patient divided in two groups: in case group patient receive 0.1 mg GnRH-a daily sc. from day 21 of previous cycle. From cycle day 2, dose of GnRH-a reduce to 0.05 mg and oral estradiol is started 6mg daily.In control group, patients receive oral estradiol 6 mg daily without GnRH_a from day 2. When endomwtrial thickness is atleast 7.5 mm ,vaginal progestrone 400 mg twice daily is started. In both group ,When endometrial thickness is at least 7.5 mm ,vaginal progestrone400 mg twice daily is started and GnRH-a is stoped in case group .Embryo transfer is done on day 4 of progestrone. Main outcomes: pregnancy test (serum BHCG) is done 14 days after ET(chemical pregnancy) . fetal heartbeat is checked 2-3 weeks after positive BHCG test(clinical pregnancy).

    این مطالعه یک مطالغه آینده نگر وتصادفی شده (با استفاده از جدول اعداد تصادفی)میباشد . هدف از این مطالعه بررسی اثر استفاده از (آگونیست گنادوتروپین)GnRH-a در آماده سازی اندومتر در سیکلهای بازکشت از فریز در بیماران با سابقه شکست مکرر لانه گزینی می باشد. معیار ورود: زنان نابارور 18 تا 42 سال ,سابقه حداقل دو شکست لانه گزینی معیار خروج: تخمک اهدایی , ضایعات داخل رحمی , سابقه کمتر از دو شکست لانه گزینی اابتدا بیماران به دو گروه تقسیم می شوند :در گروه مورد ابتدا بیماران از روز 21 سیکل روزانه 0.1 میلی گرم GnRH-a به صورت زیرجلدی دریافت می کنند و از روز دوم سیکل این میزان به 0.05 میلی گرم کاهش یافته و استرادیول خوراکی به میزان 6 میلی گرم در روز شروع می شود. در گروه شاهد بیماران بدون دریافت GnRH_a ار روز دوم سیکل 6 میلی گرم در روز استرادیول شروع می شود. زمانی که ضخامت اندومتر به 7.5 میلی متر برسد پروژسترون 400 میلی گرم دو بار در روز شروع می شود . در گروه مورد تجویز GnRH_a در روز شروع پروژسترون قطع می گردد.انتقال جنین در روز چهارم تجویز پروژسترون انجام می شود.14روز بعد از انتقال جنین سطح BHCG چک شده ودر صورت مثبت شدن (حاملگی شیمیایی)استروژن و پروژسترون ادامه می یابد. حاملگی کلینیکال در صورت مشاهده ساک حاملگی همراه با فعالیت قلب جنین تایید می شود.

    The case group (n = 34) received 0.1 mg/day of the GnRH agonist (Variopeptyl, VarianDarou, Iran), subcutaneous, from day 21 of the cycle preceding the actual FET cycle. On the second day of the cycle, the dose of GnRH agonist was reduced to 0.05 mg and 6 mg/day oral estradiol valerate (2 mg, Aburaihan Co., Tehran, Iran) was also started. When the endometrial thickness reached to 7.5 mm, vaginal supplementation of Cyclogest® pessaries (Cox Pharmaceuticals, Barnstaple, UK) at 400 mg twice daily was started and the GnRH agonist was also stopped. The control group (n = 33), received 6 mg/day oral estradiol valerate (2 mg, Aburaihan Co., Tehran, Iran) from the second day of the cycle without the GnRH agonist. In the two groups, frozen-thawed embryos were transferred on the fourth day of progesterone treatment.

    گروه مورد (34 نفر) از روز 21 سیکل قبل0.1 میلی گرم در روز آگونیست GnRH (واریوپپتیل ، واریان دارو ، ایران) ، زیر جلدی دریافت کردند. از روز دوم قاعدگی ، دوز آگونیست GnRH به0.05 میلی گرم کاهش یافت و 6 میلی گرم در روز استرادیول والرات خوراکی (2 میلی گرم ، شرکت Aburaihan ، تهران ، ایران) شروع شد. هنگامی که ضخامت آندومتر به 7.5 میلی متر رسید ، شیاف واژینال سیکلوژست ® (Cox Pharmaceuticals، Barnstaple، UK) با 400 میلی گرم دو بار در روز شروع شد و آگونیست GnRH نیز متوقف شد. گروه کنترل (33 نفر) از روز دوم چرخه بدون آگونیست GnRH شش میلی گرم در روز استرادیول والرات خوراکی (2 میلی گرم ، شرکت Aburaihan ، تهران ، ایران) دریافت کردند. در دو گروه ، رویان منجمد شده در روز چهارم درمان پروژسترون منتقل شد.

    Patients are divided into two groups of 34 patients according to permutation block method of control and intervention. Therapeutic tasks within the blocks are determined in such a way that they are random, but the desired allocation ratio is achieved in each block. There are 8 blocks in each,is 8 numbers in order to reaches sample size to 64 and one block of 4 is considered. Generate random codes using random block allocation method which will be generated with the help of Random allocation software version 1. The first person eligible to enter the study is given number one and so on until the last person eligible for number 67 is given.Using a table generated by random allocation software by number, individuals are placed in the control and intervention group. The output of Random allocation software version 1 is specified as A and B in the specified blocks, which describe the number of blocks and the number of patients in each block.

    بیماران بر اساس روش بلوک جایگشتی به دو گروه 34 نفره کنترل و مداخله تقسیم می شوند. تکالیف درمانی در داخل بلوک ها به گونه ای تعیین می شوند که به ترتیب تصادفی باشند اما نسبت تخصیص مورد نظر دقیقاً در هر بلوک حاصل شود. تعداد 8 تا بلوک 8 تایی در نظر گرفته می شودکه حجم نمونه به 64 میرسد و یک بلوک 4 تایی در نظر گرفته میشود. تولید کدهای تصادفی با استفاده از تخصیص تصادفی به روش بلوک جایگشتی که با کمک نرم افزار Random allocation software version 1 تولید خواهد شد. به اولین نفر واجد شرایط ورود به مطالعه شماره یک داده می شود و به همین ترتیب ادامه می یابد تا به آخرین فرد واجد شرایط شماره 67 داده می شود. با استفاده از جدولی که توسط نرم افزار تخصیص تصادفی تولید می گردد بر حسب شماره، افراد در گروه کنترل و مداخله قرار می گیرند. خروجی نرم افزار Random allocation software version 1 بصورت حرف A وB در بلوکهای مشخص شده که تعداد بلوک وتعداد بیمار در هر بلوک توضیح داده شده است.

Protocol summary

Study aim
This study was conducted to investigate the effects of GnRH agonist administration on the implantation rate in the FET cycles of women with RIF, prior to estrogen-progesterone preparation of the endometrium.
Design
The case group (n = 34) received 0.1 mg/day of the GnRH agonist (Variopeptyl, VarianDarou, Iran), subcutaneous, from day 21 of the cycle preceding the actual FET cycle. On the second day of the cycle, the dose of GnRH agonist was reduced to 0.05 mg and 6 mg/day oral estradiol valerate (2 mg, Aburaihan Co., Tehran, Iran) was also started. When the endometrial thickness reached to 7.5 mm, vaginal supplementation of Cyclogest® pessaries (Cox Pharmaceuticals, Barnstaple, UK) at 400 mg twice daily was started and the GnRH agonist was also stopped. The control group (n = 33), received 6 mg/day oral estradiol valerate (2 mg, Aburaihan Co., Tehran, Iran) from the second day of the cycle without the GnRH agonist. In the two groups, frozen-thawed embryos were transferred on the fourth day of progesterone treatment.
Settings and conduct
In this randomized clinical trial, 67 infertile women with history of idiopathic RIF (at least two implantation failures), undergoing FET cycles in Yazd Reproductive Sciences Institute.

Patients are divided into two groups of 34 patients according to permutation block method of control and intervention. Therapeutic tasks within the blocks are determined in such a way that they are random, but the desired allocation ratio is achieved in each block. There are 8 blocks in each,is 8 numbers in order to reaches sample size to 64 and one block of 4 is considered. Generate random codes using random block allocation method which will be generated with the help of Random allocation software version 1. The first person eligible to enter the study is given number one and so on until the last person eligible for number 67 is given.Using a table generated by random allocation software by number, individuals are placed in the control and intervention group. The output of Random allocation software version 1 is specified as A and B in the specified blocks, which describe the number of blocks and the number of patients in each block.
