Embryo-transfer
The fertilized oocytes (zygotes) are selected and further cultured until the day of embryo transfer either a) on the 2nd day (2-4 cell stages) b) 3rd day (6-8 cell stage) or c) 5th/6th day (blastocyst stage).If many oocytes are fertilized and are of “good quality” the surplus of embryos may be frozen for a possible future attempt.
The embryo transfer is a painless procedure, performed without anesthetic-usually taking 5-10 minutes and can be likened to a simple PAP test. The embryos are placed in a catheter and introduced into the uterus vaginally.
The number of embryos replaced depends on their “quality”, age of the patient and outcome of previous IVF attempts.
