In vitro fertilization is a procedure in which the eggs from a woman's ovary are removed.
They are fertilized with sperm in a laboratory procedure and then the fertilized egg called embryo is returned to the woman's uterus.
Fertilizing multiple eggs outside the womb and implanting them into the woman for the pregnancy in the hopes that one of them attaches and is carried to term.
Process of embryo transfer in IVF:
The final stage of in vitro fertilization (IVF) is embryo transfer.
Embryo transfer is the process of placing embryos inside the uterine cavity and it's the final stage of the IVF cycle.
IVF embryos are usually transferred on the second or third day after the egg retrieval, at the four to eight-cell stage.
Some embryos reach up to the blastocyst stage and are transferred 5 days after fertilization.
Fertility drugs are used during IVF to stimulate the ovaries into producing healthy eggs.
These eggs are then extracted from the ovaries of a woman and fertilized in a laboratory.
The embryos are transplanted to the woman's uterus once the fertilized eggs have multiplied.
The embryo must next attach itself to the wall of the womb or the uterus in order for a pregnancy to begin.
