EXTENDED CULTIVATION MEANS THAT THE EMBRYO IS CULTIVATED LONGER IN EMBRYOLOGY LABORATORY AND THE TRANSFER TO THE UTERUS OCCURS ONLY FIVE DAYS AFTER FERTILIZATION.
WHAT ARE THE BENEFITS OF EXTENDED CULTIVATION?
- transfer on the fifth day enables more favorable conditions for embryo implantation and penetration into the endometrium
- this procedure increases the chances of successful treatment by 10-15%.
- cells removed from the surface of the blastocyst on the fifth day after fertilization are suitable for genetic testing
- blastocysts (5-day-old embryos) can be frozen by vitrification and thus preserved with a good prognosis of development after their thawing for future cycles
