ÖZET
Amaç: İnfertilite tedavisi sırasında daha kaliteli sperm hücrelerini elde etmek için farklı sperm elde etme yöntemlerinin etkinliği uzun yıllardır
araştırılmaktadır. Bu çalışmanın amacı, yaygın olarak kullanılan iki sperm ayıklama yönteminin, kardeş oositleri kullanarak laboratuvar ve klinik
sonuçlar üzerindeki etkilerini karşılaştırmaktır. Gereç ve Yöntemler: Çalışmaya 72 hastadan elde edilen toplam 1075 olgun oosit dahil edildi. Tüm
semen numuneleri iki parçaya bölündü ve intrasitoplazmik sperm enjeksiyonundan önce pellet yüzerek veya tek katmanlı santrifüj ile hazırlandı.
Her hastanın olgun oositleri iki gruba ayrıldı ve her gruba sperm elde etme yöntemlerinden birisi ile işlem yapıldı. Sonuçlar ve Sonuç: Çalışmanın
ana sonuç ölçütü toplam blastosist gelişme oranı iken, diğer sonuç ölçütleri (fertilizasyon oranı, blastosist gelişme hızı, embriyo kalitesi, gebelik
ve implantasyon oranı) ikincil sonuçlar olarak gruplar arasında karşılaştırıldı. Pelet yüzdürme yöntemi, çalışmamızda tek katmanlı santrifüjlemeye
göre daha yüksek blastosist edinimi (toplam blastosist gelişimi ve blastosist kullanım oranı) göstermesine rağmen, aradaki fark istatistiksel
anlamlılık göstermemiştir (p> 0.05). Ayrıca fertilizasyon, embriyo gelişimi, 2. gün embriyo kalitesi, gebelik ve implantasyon oranları açısından
gruplar arasında anlamlı farklılık bulunmadı (p> 0.05). Verilerimiz, her iki yöntemin de blastosist kullanımı ve implantasyon oranları açısından
karşılaştırılabilir etkilere sahip olduğunu göstermektedir; bu nedenle farklı laboratuvarların koşullarına ve ihtiyaçlarına göre dönüşümlü olarak
kullanılabilirler.

ABSTRACT
Objective: The efficiency of different sperm sorting methods for retrieving higher quality sperm cells during infertility treatment has been under
investigation for many years. The aim of this study was to compare the effects of two commonly used sperm sorting methods on laboratory and
clinical outcomes by using sibling oocytes. Materials and Methods: 72 female patients having a total of 1075 mature oocytes and their partners
were included in this study. All semen samples were divided into two aliquots and prepared either by pellet swim up or single layer centrifugation
before intracytoplasmic sperm injection. Mature oocytes of each patient were split into two groups; and each group was assigned to one of
the sperm sorting methods. Results and Result: The main outcome measure of the study was total blastocyst development rate whereas other
outcome measures (fertilization rate, blastocyst development rate, embryo quality, pregnancy and implantation rate) were also compared between
the groups as the secondary outcomes. Although pellet swim-up method demonstrated a higher blastocyst yield (total blastocyst development and
blastocyst utilization rate) compared to single layer centrifugation in our study, the difference did not reach a statistical significance level (p>0.05).
Moreover, no significant differences were found between the groups in terms of fertilization, embryo development, embryo quality on day 2, pregnancy
and implantation rates (p>0.05). Our data suggest that both methods have comparable effects in terms of blastocyst utilization and implantation
rates; thus, may be used alternately according to the conditions and needs of different laboratories.
Keywords: Blastocyst; implantation; pregnancy; sperm sorting
