Finally, a few days after fertilization, one or two healthy embryos are replaced into the woman’s womb. To do this, the doctor or nurse inserts a plastic device called a speculum into the vagina to separate the walls, so allowing them to see the cervix or neck of the womb. A fine tube like a thin straw is inserted through the neck of the womb and one or two embryos replaced through the tube. If there are other healthy embryos, these can be frozen and stored and used in subsequent treatment cycles without the need for ovulation induction.
