In this process, the woman has to take hormonal injections to stimulate the ovaries to produce many eggs.
Once the follicles reach a mature size, the doctor administers an HCG injection to push the development and maturation of the eggs further. And right before the eggs are ovulated, they are retrieved via a small surgery. During the surgery, a sterile needle attached to suction tubing and a collecting vial is used to retrieve eggs from the ovary through the vaginal wall.
Once the fluid containing these eggs is taken from the follicles and into the vials, they are handed over to the embryologist. The expert then finds the egg, places them on a petri dish and then fertilizes them using their partner’s sperm.
The fertilized eggs (embryos) are then allowed to grow and develop for typically 3 to 5 days. Embryos displaying healthy development, are then transferred into the uterine cavity under ultrasound guidance, using a sterile catheter.
