Abstract

Intracytoplasmic sperm injection (ICSI) is one of the most important techniques used for the treatment of male infertility. Before ICSI oocytes have to be denuded from cumulus and corona cells using a combination of enzymatic and mechanical methods. In this study 40 IU/ml hyaluronidase has been used to denude the oocytes. The aim of this study is to investigate the effects of the incubation of hyaluronidase applicated oocytes before ICSI on fertilization, embryo development and pregnancy rates. Materials and methods: Patients were randomly selected according to the days of the week. In 114 patient ( Group I) oocytes were incubated in 37 C , %5 CO2 and %5 O2 for 30-60 minutes before ICSI. In 136 patient ( Group II ) ICSI is performed immediately after denudation. Results: There was no statistical difference on fertilization rates and number of grade I embryo that were transferred between two groups. Although implantation rates were higher in group II that no incubation had been performed, there was no statistical difference between two groups. Discussion: ICSI can be performed immediately after denudation with hyaluronidase.

Özet

Yardımcı üreme tekniklerinde infertilite tedavisinde kullanılan en önemli tekniklerden birisi intrasitoplazmik sperm enjeksiyonudur. ICSI'den önce uygulanan denudasyon işleminde oositlerin etrafındaki korona-kumulus kompleksi mekanik ve enzimatik yolla uzaklaştırılır. Bu çalışmada, 40 IU/ml hyaluronidaz enzimi kullanılarak denudasyon işlemi yapılmış oositlerin ICSI'den önce inkübasyonsuz veya inkübe edilerek kullanılmalarının fertilizasyon, embriyo kalitesi ve gebelik oranı üzerine olan etkilerinin incelenmesi amaçlanmıştır. Materyal - Metod: Hastalar haftanın günlerine göre randomize edildiler.114 hastada (GrupI) hyaluronidaz işleminden sonra oositler 30-60dak. süreyle 37 C'de %5.5 CO2, %5 O2'de inkübe edilmiştir. Bu inkübasyon sonrasında mikroenjeksiyon işlemine alınmıştır. 136 hastada ise (Grup II ) hyaluronidaz işleminden hemen sonra ICSI işlemi uygulanmıştır. Bulgular: Hyaluronidaz uygulanmasından sonra oositleri inkübe edilen ve edilmeyen gruplarda fertilizasyon oranları ve transfer edilen Grade I embriyo sayıları arasında istatistiksel fark saptanmamıştır. İmplantasyon oranı inkübasyon uygulanmayan grupta (Grup II) yüksek görülmekle birlikte iki grup arasında anlamlı bir fark yoktur. Sonuç: Hyaluronidaz kullanılarak yapılan denudasyon işleminin hemen sonrasında mikroenjeksiyon işlemine başlanabilir.
