Sadece G1 ve G2 iyi kalitede blastokistler dondurulmuştur. >43 yaş olanlar, tedavi siklus kayıtlarında eksik verileri olan veya takipten çıkan hastalar çalışma dışı bırakılmıştır. Tüm hastalara âdetin 2. günü 6 mg sabit dozdan oral Ö tedavisi başlanmıştır.Östradiyolkullanım süresi embriyo transfer (ET) günü planlamasına göre 8 ile 14 gün arası değişmektedir. Toplamda 241 hastanın VET siklusu Ö kullanım sürelerine göre (Grup 1: <12 gün, n=105; Grup 2:³12 gün, n=136) analiz edilmiştir. Çalışmanın primer sonuç değişkeni CDO’ dır.Bulgular:Toplam 241 VET siklusundaki P kullanımı öncesi E kullanım süresi: 8 gün (%3), 9 gün (%8), 10 gün (%16), 11 gün (%16.5), 12 gün (%22.5), 13 gün (%20.5), 14 gün (%13.5) şeklinde dağılım göstermektedir.Östradiyoltakviyesinin 12 günün altında kullanımının 12 gün üzerinde kullanımına kıyasla CDO üzerine anlamlı etkisi yoktur (OR=1.25; %95 CI[0.75-2.1], p=0.38). Klinik gebelik, erken ve fetal kayıp oranları da gruplar arasında benzerdir. Ortalama endometrial kalınlık gruplar arasında benzerdir (9.5mm).Östradiyoltakviyesinin reprodüktif sonuçlarla ilişkisi her gün için ayrı ayrı değerlendirildiğinde de anlamlı bir fark saptanmamıştırSonuç:Vitrifiye embriyo transfer sikluslarında genel kabul görenden daha kısa östradiyol kullanımı canlı doğum oranlarını etkilememekte, abort riskini artırmamaktadır. Bu durum test edilmemiş ancak kuvvetle kabül görmüş bu protokolü sorgulanır kılmaktadır KW - blastokist KW - vitrifiye KW - embriyo transferi KW - östrojen KW - endometriyum N2 - Objective:To evaluate the effect of a shorter duration of estradiol (E) exposure prior to progesterone (P) administration on live birth rate (LBR) in vitrified warmed embryo transfer (VWET) cycles.Materials-Methods:A retrospective cohort study was conducted in the American Hospital (Koc University affiliated private hospital) between October 2015 and October 2017. All VWET cycles with a single blastocyst transfer using artificial endometrial preparation without GnRH agonist pretreatment were included. Only G1 and G2 good quality blastocysts had been cryopreserved. Women >43 years of age, treatment cycles with incomplete data and women who were lost to follow-up were excluded.Participants/material, setting, methods:All women received oral E treatment starting on day 2 of menstrual bleeding in a fixed dose of 6mg/day. The duration of E administration varied from 8 to 14 days due to concerns regarding embryo transfer scheduling. A total of 241 patients with vitrified warmed single blastocyst transfer cycles were analyzed according to the duration of E administration (Group 1: <12 days, n=105; Group 2:³12 days, n=136). The main outcome measure was LBR per transfer.Results:Among a total of 241 patients with vitrified warmed blastocyst transfers, E exposure prior to P supplementation was as follows: 8 days (3%), 9 days (8%), 10 days (16%), 11 days (16.5%), 12 days (22.5%), 13 days (20.5%), 14 days (13.5%).LBR was not significantly affected when the E treatment was administered for less than 12 days (OR=1.25; 95%CI[0.75-2.1], p=0.38). Mean endometrial thickness was similar among the groups (9.5mm). When the patients were sub-divided according to the duration of E treatment, primary and secondary outcomes were likewise similar.Conclusion:Shorter than the normally accepted duration of E administration yields similar LBRs in VWET cycles, thus questioning the need to adhere strictly to an untested protocol.
