If you’ve been investigating different types of fertility treatments, you may have come across the process known as blastocyst embryo transfer (sometimes referred to colloquially as “blast transfer”.)
The blastocyst embryo transfer procedure has been successfully used for decades; in fact, this was how the first “test tube baby” was conceived. However, it may seem a confusing process, so we at RSI, one of Philadelphia’s premiere fertility clinics, want to take the mystery out of the procedure.
First and foremost, it’s important to understand what a blastocyst is. As an embryo develops naturally, it sometimes becomes a collection of 100+ cells. This collection is referred to as a blastocyst and takes a little less than a week to reach this stage. The blastocyst has an outside (which will become the placenta) and an inside (which will become the fetus.)
Not all fertilized eggs become blastocysts; in fact, only about one fifth of them will reach this stage in nature, although some fertility specialists have been able to do better than that number in a clinical setting. They prefer to use blastocysts to do transfers, as they have a better chance of implanting than do other cells and thus producing a successful IVF treatment outcome.
Of course, there’s no guarantee that a blastocyst will implant. Even the most solid blastocyst embryo transfer doesn’t equate to a live birth. Yet it does increase the odds for parents-to-be.
If you’re interested in blastocyst embryo transfer, please contact RSI today for a consultation with one of our fertility specialists.
Since the first “test tube baby” (a child named Louise Brown) was born in England in 1978, more than 3 million children have come into the world thanks to fertility treatments… and more are likely to become part of our society as
