NCT02059304

Brief Summary

The aim of this study is to examine the potential value of cervical length (CL) measurement with embryo transfer catheter in the prediction of spontaneous preterm deliveries in intracytoplasmic sperm injection (ICSI) cycles. Preterm birth is the leading cause of perinatal death and handicap in children. It is clear that ICSI pregnancies are at high risk groupfor preterm delivery (PTD). In singletons there is an estimated two-fold increased risk following ICSI. CL measurement with ultrasound in mid-trimester (22-24 weeks) is the best method for the prediction of PTD: The shorter the CL, the higher risk of PTD. Recent evidence suggests that at first trimester (11-13 weeks), the risk for PTD is inversely related to CL. It has been shown that the measurement of CL on pregnancy is an effective method for identification of the group at high risk for PTD. In embryo transfer, catheter is placed the through cervical canal. The method we will use in this study, CL measurement with transfer catheter, will give more precise results than measurement with ultrasound. No study has been performed to evaluate the prediction of PTD by analyzing measurements of CL, preconceptionally. Our study will be the first in this topic. There is a certain disadvantage of measuring CL during pregnancy: The effectiveness of prophylactic administrations (progesterone, cervical cerclage etc.) may be inversely related to the gestation at which treatment is initiated. If we know the risk of PTD before gestation, single embryo transfer will be preferred to avoid from multiple pregnancies that also increase the relative risk of PTD, in ICSI pregnancies.
