Blastocyst Culture & Transfer
Growing embryos to day 5–6 so the strongest can be chosen for transfer.
- Day 5–6 extended culture
- Better embryo selection
- Supports single-embryo transfer
About this treatment
A blastocyst is an embryo that has developed for five to six days after fertilisation, reaching a more advanced stage with many more cells. Growing embryos to this stage — blastocyst culture — lets our embryologists see which are developing best.
Transferring a single strong blastocyst improves the chance of implantation while keeping a single, safer pregnancy. Extended culture also pairs naturally with genetic testing and our freeze-all approach.
Who it's for
- Patients with several good embryos to choose from
- Anyone wanting single-embryo transfer
- Cycles using genetic testing (PGT)
Key benefits
- Selects the strongest embryo
- Higher implantation potential per transfer
- Supports safer single-embryo transfer
- Works alongside PGT and freeze-all

Blastocyst Culture — your questions
Common questions about this treatment. Anything else? Our team is happy to talk it through.
Growing to blastocyst lets us see which embryos are developing strongly, improving selection. Your embryologist advises the best day to transfer based on your embryos.
Not all — typically only the strongest make it to day 5–6. This is part of how the technique helps select embryos with the best potential.
