Abstract

Objective: The aim of this study is to evaluate the impact of PGD on implantation and ongoing pregnancy rates in couples whose male partner was diagnosed as having dominantly (>50%) spermatozoa with macrocephalic forms together with the other forms including multi-tailed sperm, sperm without tails and globozoospermia. Institution: İstanbul Memorial Hospital, ART, Reproductive Endocrinology and Genetics Centre, İstanbul Materials and Methods: 83 ART cycles of 73 couples in which male partner shows macrocephalic sperm characteristics were retrospectively analyzed in Istanbul Memorial Hospital, ART, Reproductive Endocrinology and Genetics Centre. In 23 cycles, suitable embryos were biopsied for p reimplantation genetic diagnosis (PGD) was performed on day 3 of embryo development. Blastomeres were then analyzed by fluorescent in situ hybridization (FISH) for chromosomes 13, 18, 21 Xand Y. In cases where PGD was perfomed, chromosomally normal embryos were selected for transfer procedure. Results: Out of 82 embryos biopsied in 23 PGD cycles, sixtynine of them gave interpretable results (84,1%) and abnormalities detected in 32 blastomeres analyzed (46,4%). Once embryos were selected by preimplantation genetic diagnosis (PGD) and transferred 27 cycles a 33.3% pregnancy rate was achieved with the statistically higher implantation rate of 25.0% compared to 54 non-PGD embryo transfer cycles with 12,3% implantation rate (p

Özet

Amaç: Bu çalışmada, semen analizi sonrası spermlerin belirgin olarak (>%35) makrosefalik formda olduğu ve bununla birlikte, çok kuyruklu sperm, kuyruksuz sperm ve globozoospermi olarak tanımlanmış sperm içeren vakalarda preimplantasyon genetik tanı (PGT) tekniğinin implantasyon ve devam eden gebelik oranları üzerindeki etkisi değerlendirilmektir.Çalışmanın Yapıldığı Yer: İstanbul Memorial Hastanesi, YÜT, Reprodüktif Endokrinoloji ve Genetik Merkezi, İstanbul Materyal ve Metod: Çalışmada İstanbul Memorial Hastanesi YÜT, Reprodüktif Endokrinoloji ve Genetik Merkezine başvuran ve yardımcı üreme teknikleri (YÜT) programına alınan ve makrosefalik sperm özelliği gösteren 73 çifte ait 83 siklus retrospektif olarak incelenmiştir. 23 siklusta elde edilen embriyolarda, embriyo gelişiminin 3.günü uygun gelişim düzeyinde olanlarına preimplantasyon genetik tanı (PGT) amaçlı biyopsi işlemi uygulanmıştır. Elde edilen blastomerler floresan in situ hibridizasyon (FISH) tekniği kullanılarak 13., 18., 21. X ve Y kromozomları yönünden incelenmiştir. PGT yapılan grupta FISH sonucu normal kromozom yapısına sahip embriyolar ile transfer uygulanmıştır. Bulgular: 23 PGT siklusunda biopsi yapılan 82 embryonun 69’unda floresan in situ hibridizasyon (FISH) sonrası sonuç alınmış (%84.1), analiz edilen 32 embriyoya ait blastomerede anomali saptanmıştır (%46.4). PGT sonrası kromozom yapısı normal olarak tespit edilen embriyolar ile uygulanan embriyo transfer işlemi sonrası 21 siklusta %33.3 gebelik oranı ve %25 implantasyon oranı elde edilmiştir. Bu oran PGT yapılmayan 54 embryo transfer siklusunda elde edilen %12.3’lük implantasyon oranına göre istatistiksel olarak, daha yüksek bulunmuştur (p
