A multiple pregnancy is an undesired outcome of assisted reproduction. Current embryo selection technologies are inefficient in identifying the embryo with the highest implantation potential. Time lapse (TL) embryo monitoring provides additional information about embryo development and therefore may aid embryo selection. The investigators aim is to study whether TL monitoring is superior to traditional embryo observation when a single blastocyst is selected for transfer (ET).

Further study details as provided by Kaali Institute IVF Center:

Primary Outcome Measures:
  • clinical pregnancy [ Time Frame: clinical pregnancy will be assessed at week 8 of pregnancy ] [ Designated as safety issue: No ]
    intrauterine pregnancy with heartbeat

Secondary Outcome Measures:
  • implantation rate [ Time Frame: implantation rate will be assessed at week 6 of pregnancy ] [ Designated as safety issue: No ]
    intrauterine sac/ embryo transferred

Other Outcome Measures:
  • time lapse score [ Time Frame: the time lapse score is assessed on the day of embryo transfer (day 5 after the egg retrieval) ] [ Designated as safety issue: No ]
    a score based on 8 observations by time lapse monitoring

Estimated Enrollment: 50
Study Start Date: January 2012
Estimated Study Completion Date: March 2013
Estimated Primary Completion Date: January 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: time lapse embryo observation
Upon fertilization embryos are placed in an incubator that is hooked up to a monitor that allows continuous embryo observation
Other: observation of embryo development by time lapse embryo monitoring versus standard once a day embryo evaluation
standard embryo monitoring
upon fertilization embryos are observed once a day by the embryologist to check for development
Other: observation of embryo development by time lapse embryo monitoring versus standard once a day embryo evaluation
