Abstract

Objective: This prospective study was set up in order to analyze whether additional treatment (cutting off supernumerous cumulus cells; adding hyaluronidase) of the cumulus-oocyte-complex (COC) would help to improve treatment outcome. Material and Methods: COCs from 50 patients were prospectively subdivided into a control group A (no manipulation of COC) and two study groups. In group B, surplus cumulus cells were cut off using syringes, and in the second study group COCs were incubated with a 1:11 dilution of hyaluronidase (final concentration 7 IU/l). Main outcome measures were fertilization rate, embryo development, as well as rates of implantation, pregnancy, and live birth. Results: Fertilization was higher in group C as compared to the untreated control group A (p

Özet

Amaç: Bu prospektif çalışma, kümülus-oosit-kompleksine (KOK) ilave işlemin (çok sayıdaki kümülus hücrelerinin kesilip ayrılması; hiyaluronidaz eklenmesi) tedavi sonuçlarını iyileştirmede yardımcı olup olmayacağını analiz etmek için yapıldı. Gereç ve Yöntemler: Elli hastadan elde edilen KOK’lar prospektif olarak bir kontrol grubuna (Grup A; KOK manipülasyonu yok) ve iki çalışma grubuna bölündü. Grup B’de, artık kümülus hücreleri şırıngalar kullanılarak kesilip ayrılmıştır ve ikinci çalışma grubunda KOK’lar hiyaluronidazın 1:11’lik dilüsyonu (son konsantrasyon 7 IU/l) ile inkübe edildi. Başlıca sonuç ölçümleri fertilizasyon oranı, embriyo gelişmesi yanı sıra implantasyon, gebelik ve canlı doğum oranlarıydı. Bulgular: İşlem yapılmamış kontrol grubu A’ya kıyasla fertilizasyon, grup C’de daha yüksekti (p
