Thawing Eggs

When you are ready to become pregnant, you will need to return to the fertility clinic and discuss the procedure for thawing frozen eggs and fertilizing them.

Talk to your fertility doctor about how many eggs to thaw and how many should be transfered for your particular age and situation. 

Once the eggs are thawed, embryologists in the fertility clinic lab will typically use a  procedure known as intracytoplasmic sperm injection (ICSI) to fertilize them with your partner's sperm. With ICSI, a single sperm is injected into the egg after it is thawed.

Once the fertilized eggs have grown into embryos, one or two can be transfered with ultrasound guidance into your uterus — generally on day 3 or day 5 of development (once the embryo has reached the blastocyst stage). The embryo transfer is typically an outpatient procedure done under minimal sedation.

A predetermined number of embryos are loaded into a fine transfer catheter, and guided by ultrasound, the fertility doctor deposits the embryos in the uterus with the goal of the embryos implanting in the uterus and growing into a healthy pregnancy.

After the procedure, you will rest for a few hours before you are discharged, and you may be prescribed progesterone to help increase the chances of pregnancy and sustaion a pregnancy.
