Embryo time lapse imaging

CARE Fertility are leaders in embryo time-lapse imaging


Our unique CAREmaps technology, developed by CARE scientists, allows us to record thousands of images of an embryo as it develops – and this helps our embryologists to understand which embryo has the best chance of growing into a baby.

Whilst there are many factors which can influence the outcome of IVF treatment, transferring the most viable embryos is arguably the most critical element of successful treatment.

Time Lapse Imaging gives us very detailed information about how your embryos are developing, and this helps us to identify the embryos which have the most potential to develop, resulting ultimately in a baby.

World first study shows computer algorithm can rank time lapse human embryos according to the probability of a live birth

“Cameras in our closed incubation systems at CARE (CAREMaps*) give us images every 10 minutes of the developing embryo – leaving it undisturbed for five full days.  As the first UK clinic to offer the time lapse Embryoscope to patients we have now examined images from over 500,000 embryos - an unprecedented amount of data revealing previously hidden aspects of early human development.”


Our latest published work involves 781 single blastocyst embryo transfers where our computer algorithms ranked embryos A B C or D.  From that cohort, 354 (45.3%) of patients had an A ranked embryo.  273 (35.0%) ranked B, 86 (11.0%) ranked C, and 68 (8.7%) were ranked D.   There were 329 (42.1%) live births.  186 – (52.5%) from transfers with an A ranked embryo, 107 (39.2%) from rank B, 27 (31.4%) from rank C and just 9 (13.2%) from D ranked embryos.

“We concluded that time-lapse imaging morpho-kinetic based algorithms for blastocysts can provide objective hierarchical ranking of embryos to predict live birth & may have greater discriminating power than conventional blastocyst morphology assessment”

“Not all patients are fortunate enough to have an A ranked embryo as our data shows but if they do then this gives them the best chance of a pregnancy.  We also demonstrated that an A rank embryo has a 233% chance of a live birth when compared to a D grade.  Our statistical analysis was comprehensive in accounting for all the female characteristics that could affect the embryo outcome – including age”

Jaycie's journey

Using CAREmaps, we’ve brought the magic of human conception to life. For Jaycie’s Journey we took millions of images showing her growth and development as an embryo right from the moment of fertilisation, then followed her journey as she grew into a toddler.
