Blastocyst Culture Procedure in Mexico

How is Blastocyst Culture carried out?
The Blastocyst culture transfer is a similar procedure to IVF.

• IVF takes place and the fertilized egg, the embryo, is incubated in a laboratory.
• Instead of implanting the embryo after two or three days of incubation, blastocyst transfer implants the embryo after five or six days.

Who is a suitable candidate for Blastocyst Culture?
Blastocyst culture is more appropriate for people who have had failed day three transfers, or have concerns or health risks surrounding multiple births. Younger patients are more suitable, as are women with more than six high quality embryos in incubation at day three.

What are the chances of success with Blastocyst Culture?
The loss-rate for embryos is high and many women don’t have any surviving embryos at day six – according to the Human Fertilisation and Embryology Authority, around 50 percent of embryos die after day three. The clinic needs to be proficient at the blastocyst culture procedure for effective transfer to take place.

According to the Human Fertilisation and Embryology Authority, embryos that survive to day six have a 50 percent chance of success, compared with 35 percent in IVF without blastocyst transfer.
In 2006 in women receiving IVF using the blastocyst culture procedure, the percentage of cycles that resulted in a live birth was:

• 57 percent for women aged under 35
• 50 percent for women aged between 35-37
• 38 percent for women aged between 38-39
• 33 percent for women aged between 40-42
