Which human embryos make it?

New research helps predict which human embryos are most likely to succeed

When assisting conception with in vitro fertilisation, embryologists need to achieve a delicate balance: transfer too many healthy embryos, and a woman faces the potential danger of twins or triplets; transfer too few, and a woman risks having to repeat the process or not having a child at all. Human fertilisation, as it turns out, is an uncertain process both inside and outside of fertility clinics. This video from KQED San Francisco’s science documentary series Deep Look shows how researchers are getting closer to making in vitro fertilisation a more precise science.
