Primaire uitkomstmaten
The primary aim is to study whether blastocyst stage embryo transfers (day 5) improves the cumulative LBR in IVF/ ICSI patients with a good prognosis (> 3 zygotes on day 1 after oocyte retrieval).
Achtergrond van het onderzoek
Rationale: The last years there is an ongoing debate on which embryo transfer policy in IVF/ICSI is more effective: blastocyst stage (day 5) or cleavage stage (day 3) transfer.The cumulative live birth rate(LBR) after IVF/ICSI is expected to be 8% higher after blastocyst stage embryo transfers compared to cleavage stage embryo transfers. Furthermore, the time to pregnancy will be shorter and less expensive IVF/ICSI treatments are necessary.
Objective: To determine whether blastocyst stage embryo transfers improve the cumulative live birth rate compared with cleavage stage embryo transfers in IVF/ICSI treatments.
Study design: Multicentre Randomized controlled trial
Study population: Women under 43 years receiving a IVF/ICSI treatment.
Intervention: Blastocyst stage (day 5) embryo transfer
Comparison: Cleavage stage (day 3) embryo transfer
Main study parameters/endpoints: Cumulative live birth rate per started IVF/ICSI cycle, time to pregnancy, costs.
Nature and extent of the burden and risks associated with participation, benefit and group relatedness: The risk associated with the blastocyst transfer policy is a lower amount of embryos available for transfer or cryopreservation as some embryos will arrest in their development in vitro. The potential benefit is a higher chance of pregnancy and a shorter time to pregnancy with the blastocyst transfer policy, as valued by patients. There are no extra burdens, efforts or costs to be expected for the couples. Subjects who participate fill in questionnaires at the start and end of the study, as well as on the 4th month after ovum pick-up.
Doel van het onderzoek
The cumulative live birth rate after IVF/ICSI is expected to be 8% higher after blastocyst stage embryo transfers (day 5
compared to cleavage stage embryo transfers (day 3). Furthermore, the time to pregnancy will be shorter and less expensive
IVF/ICSI treatments are necessary.
Onderzoeksopzet
The study endpoints for the subject are: after delivery, 12 months after the ovum pick up or when no pregnancy occurs after the IVF treatment cycle.
4 months after the ovum pick-up, a questionnaire concerning the quality of life is send to the subjects.
