Time-lapse embryo imaging is an emerging non-invasive embryo selection technique used in reproductive biology. It is used to help select embryos with lower risk of defects and/or greater potential of implantation. The procedure involves taking thousands of pictures of the growing embryo in vitro during incubation to study morphology and morphokinetic parameters.^[1]

In terms of pregnancy rates, live births, or the risk of stillbirth or miscarriage there is a lack of evidence of sufficient quality to know if there is any difference between time-lapse embryo imaging and conventional embryo assessment in in-vitro fertilisation (IVF).^[2] Further trials are needed in order to determine whether time-lapse embryo imaging can impact on outcomes such as live-birth for couples undergoing IVF or ICSI.^[3]
