Camera technologyThe selfie that can help me get pregnant Selecting the right embryo to give you back is crucial if you are going to achieve a pregnancy after IVF/ICSI. We know that. • Looks aren't everything. An embryo can look good but not have the potential to create a pregnancy.
How can we assess an embryo’s potential ? Time lapse imaging of the growth of each embryo. • We examine the embryo growth very carefully for any abnormal growth events that will adversely affect its potential to create a pregnancy. • A digital video recording is obtained for each embryo by taking a photograph every 10 mins. • There are several systems that are able to do this
MIRI TL from ESCO Bench top incubator combined with a time lapse
Individual compact camera and digital inverted microscope units.
Embryo time lapse culture dish Each well which holds an embryo is about the side of a full stop.
A video recording of each embryo is obtained for up to 6 days growth depending on how the embryos grow. Embryo selection is either made on day 3, 5 or 6. Most abnormal growth events are observed during the first and second cleavages
Key observation points currently correlated embryos least likely to create a pregnancy • One cell to 3 cell (Video) • 2 cell to 5 cell (Video) • Re absorption of blastomeres (Video) • Fragmented or arrested development ( video) • Clear Abnormal development (Video) • Extended period between 3 cell and 4 cell (Graph) • Slow growth between key stages (Graph) • Poor overall morphology
Morphology assessment complements time lapse imaging data Cleavage stage embryo • Clear cells (Blastomeres) of equal size. • Correct number of blastomeres for the embryo age • Presence or absence of extra cellular fragmentation Advanced stage embryo • Expanded blastocyst showing clear and well developed ICM and trophectoderm by embryo age day 5 or 6.
Day 3 good Prognosis embryo Optimal growth curve, no abnormal growth events during the cleavage stages and good morphology
Very good Prognosis embryoOne that has reached a good quality blastocyst on day 5 or day 6 with no abnormal growth events and good cleavage morphology
Two examples demonstrating how we select the right embryos for transfer Video 1 • Embryo Selection at day 3 of culture using time lapse • Video 2 Embryo Selection at day 5 of culture using time lapse and morphology assessment
Embryo Selection at day 3 of culture using time lapsePatient had 5 embryos
Embryo 2During the first division splits off a large fragment
Embryo 5 No abnormal growth events observedTransferred embryo and positive pregnancy test.
