Effect of gonadotropin releasing hormon agonist addition to routine luteal phase support in intracytoplasmic sperm injection-embryo transfer cycles on pregnancy rates and outcomes

Abstract

Amaç: GnRH-a uzun protokol ve GnRH-anta protokol ICSI-ET sikluslarında rutin Luteal Faz Desteği ((LFD)’ne GnRH-a eklenmesinin gebelik oranlarına ve sonuçlarına etkisini araştırmak Gereçler ve Yöntem: Bu prospektif randomize çalışmaya ICSI-ET ile tedavi edilen yüz sekiz infertil çift dahil edildi. Hastalar iki farklı ovulasyon indüksiyon protokolüne tabi tutulmak için rastgele olarak iki gruba ayrıldı. Grup I'e GnRH-a uzun protokolü ve grup II'ye GnRH-anta protokolü uygulandı. İki protokol ile tedavi edilecek kadınlar da iki alt gruptan birine rastgele olarak ayrıldı. Ib ve IIb alt gruplarına, rutin LFD'ye [90 mg / gün vajinal progesteron artı 4 mg 17β Estradiol] ek olarak ET'den sonra 5. ve 10. günlerde löprolid asetat (0.5 mg s.c.) enjeksiyonları uygulandı. Diğer iki alt gruba (grup la ve IIa) ise sadece rutin LPD verildi. Bulgular: Toplanan toplam oosit ve MII oosit sayısı, grup Ia'da grup Ib'den anlamlı olarak daha yüksekti. Grup I ve II'de alt gruplar arasında klinik gebelik, yumurtalık hiperstimülasyon sendromu (OHSS), çoğul gebelik, kürtaj, devam eden gebelik ve canlı doğum oranları açısından fark yoktu. Sonuç: GnRH-a uzun protokol ve GnRH-anta protokol ICSI-ET sikluslarında GnRH-a'nın rutin LPD'ye eklenmesinin devam eden gebelik, kürtaj, çoğul gebelik, OHSS, klinik gebelik ve canlı doğum oranları üzerinde hiçbir etkisi olmadığı görülmektedir.

Effect of gonadotropin releasing hormon agonist addition to routine luteal phase support in intracytoplasmic sperm injection-embryo transfer cycles on pregnancy rates and outcomes

Abstract

Abstract: Aim: To investigate the effect of gonadotrophin releasing hormone agonist (GnRH-a) addition to luteal phase support (LPS) in intracytoplasmic sperm injection-embryo transfer (ICSI-ET) cycles of GnRH-a long protocol and GnRH antagonist (GnRH-anta) protocol, on pregnancy rates and outcomes. Materials and Method: One hundred and eight infertile couples treated with ICSI-ET were included in this prospective randomized study. Patients were randomly divided into two groups to undergo two different ovarian stimulation protocols. GnRH-a iong protocol was applied to group I and GnRH-anta protocol was applied to group II. Women to be treated by each of the two protocols were also randomly assigned to one of the two subgroups. Subgroups Ib and IIb received leuprolide acetate (0.5 mg s.c.) injections on the 5th and 10th days after ET in addition to routine LPS [90 mg/day of vaginal progesterone plus 4 mg of 17β Estradiol]. Only routine LPS was given to other two subgroups (groups la and IIa). Results: The total number of retrieved oocytes and MII oocytes were significantly higher in group Ia than in group Ib. There were no differences between subgroups in groups I and II regarding clinical pregnancy, ovarian hyperstimulation syndrome (OHSS), multiple pregnancy, abortion, ongoing pregnancy and live birth rates. Conclusion: Addition of GnRH-a to routine LPS in ICSI-ET cycles of GnRH-a long protocol and GnRH-anta protocol seems to have no effect on ongoing pregnancy, abortion, multiple pregnancy, OHSS, clinical pregnancy and live birth rates.
