Abstract
Objective: To predict the reproductive potential of embryos via Raman spectroscopy evaluation of the spent culture media as well as with a conventional morphologic evaluation. Materials and Methods: Women of reproductive age (n=31) who were treated for unexplained infertility and scheduled for single embryo transfer were invited to participate in this prospective study. After the embryos were removed from the culture, the spent culture media were stored at -80 °C after snapfreezing in liquid nitrogen. Results: Fifteen patients were clinically pregnant, and 16 patients were clinically non-pregnant. Clinical pregnancy was predicted using Raman spectroscopy in 93% (14/15) of clinically pregnant patients, and in 62.5% (10 out of 16) of clinically non-pregnant patients. The sensitivity of the Raman spectroscopic analysis was 93% and the specificity was 62.5%. Conclusion: Metabolomic evaluation of spent embryo culture media is an emerging technique with promising objective results. However, there is clearly room for improvement.
Özet
Amaç: Embriyoların üreme potansiyelini belirlemede kültür medyasını Raman spektroskopik analizle ve süregelen morfolojik değerlendirmeyle karşılaştırılmasıdır.Gereç ve Yöntemler: Açıklanamayan infertilite tedavisine göre ve tek embriyo transferi olacak 31 üreme yaşındaki kadın bu prospektif çalışmaya katıldı. Embriyolar kültürden alındıktan sonra, kültür medyası -80 °C'de likit nitrojende donduruldu.Bulgular: On beş hastada klinik gebelik bulunmuşken, 16 hastada gebelik bulunmamıştır. Klinik gebelik tahmini Raman spektroskopiyle %93 (14/15), gebe olmayan hastalarda ise %62,5 (10/16) olmuştur. Raman spektroskopik analizin sensitivitesi %93, spesifitesi %62,5 şeklindedir.Sonuç: Embriyo kültür medyasının metabolomik değerlendirmesi objektif sonuçlar doğurabilir. Öte yandan metodun geliştirilmesi ihtiyacı gerekmektedir.
