If you have only two embryos, should you transfer both of
them ? or should you transfer one and freeze the other one?
This is a common quandary for patients with a poor ovarian
If you have 2 top-quality blastocysts, what should your
strategy be ? Should you transfer one and freeze the other ? Or transfer both
If you put both together, you increase your chance of
getting pregnant in that cycle - but this is an unfair comparison - after all, you
shouldn't compare apples to oranges !
You should compare transferring two embryos at one time , with
transferring one embryo at a time in two consecutive cycles.
And the pregnancy rate with transferring a single embryo
in two consecutive cycles - a sequential single embryo transfer ( SET) is
actually better , because you need to add the chances of getting pregnant in two
The cumulative conception rate with two SETs is better that
transferring two embryos in a single cycle.
The risk for the babies is also less, because you don't
have to worry about the problem of preterm births because of a twin pregnancy
