Are You Aware of These Improvements in IVF Technology?
Improvements in IVF technology and embryo culture are helping patients achieve a higher pregnancy rate of healthy singleton babies, says Dr. Matthew Lederman. Culturing embryos to the blastocyst stage and performing comprehensive chromosomal screening to determine the single best embryo to transfer, optimizes pregnancy rates and reduces multiple pregnancy rates, explains Lederman, a fertility doctor with RMA of New York.
Advancements and improvements in IVF culture conditions have enabled embryos to be cultured successfully to the blastocyst stage (a day 5 or 6 embryo) and transferred into the uterus at a more “natural” time. An embryo that is created naturally in a woman typically does not enter the uterus until day 5 or 6 following fertilization.
An advantage of extending culture to the blastocyst stage is that the embryologists can more accurately identify the best quality embryos, thereby reducing the number of embryos needed to be transferred.
Single Embryo Transfer
A blastocyst stage transfer affords the opportunity of choosing the more viable embryo for transfer, thus optimizing the pregnancy rates while reducing the multiple pregnancy rates. Embryos are carefully analyzed, graded, and, in a single embryo transfer, the highest graded blastocyst is selected for transfer into the mother.
Comprehensive Chromosomal Screening
Comprehensive chromosomal screening (CCS), is an advanced screening technique involving biopsy of the embryo, which identifies chromosomally normal embryos prior to embryo transfer. This embryo screening technique has increased the frequency of single embryo transfers, decreased the incidence of multiple gestations, decreased the incidence of miscarriage and has helped reduce the time to pregnancy since time lost to both failed cycles and miscarriages are minimized.
