| Treatments - Blastocyst Culture and Transfer |
A blastocyst is an embryo that has developed for five to six days after fertilization. When combined with IVF or ICSI treatments this gives the embryologist the opportunity to select those embryo(s) which are more likely to implant.
When would you need Blastocyst Culture treatment?
Many patients undergoing IVF and ICSI treatment have more embryos available than are required for transfer. In order to select the best embryos for transfer and thus improve the outcome of treatment, it is sometimes desirable to culture the embryos past day 2 or day 3 stage.
This extended culture allows embryos to develop into blastocysts and gives the embryologist the opportunity to select those embryo(s) which are more likely to implant. Selection of embryo(s) for transfer on day 5 should allow the transfer of fewer embryos. This in turn should reduce the risk of multiple pregnancy while maintaining the overall chance of a pregnancy for the individual patient. |
