Blastocysts, or fertilized embryos in their fifth day of development, may offer
a viable alternative to Day 3 embryo transfer for some IVF patients.
Depending on the patient's age, diagnosis and the quantity and quantity of
embryos available, our team of embryologists may recommend waiting until Day
5 instead of Day 3 for embryo transfer. Embryos which are capable of
progressing to the blastocyst stage of development typically result in higher
implantation and pregnancy rates with fewer transfered embryos, reducing the
risk of higher order multiple gestation.
This technique is typically used for patients who respond well to ovarian
stimulation and produce numerous healthy eggs. Your embryologist will review
your case personally to determine if you may be a candidate for this procedure.
