The path to parenthood is different for everyone. Donor egg IVF is specifically for those who are unable to use their own eggs. Typically, donor eggs are used when a female’s eggs are of poor quality. Poor egg quality is usually associated with age but can occur in women of any age.

Premature ovarian failure, meaning a woman is beginning menopause at an early age, is a common cause of poor egg quality or an overall lack of eggs. A similar condition, known as diminished ovarian reserve, means that a woman has fewer eggs left in the ovaries, and usually the eggs have genetic defects, which often results in miscarriage. Women can also have genetic conditions where they use donated eggs in order to avoid passing the genetic disorder to their children.

What is IVF?

IVF is an assisted reproductive technology where an egg and sperm are manually combined in a laboratory for fertilization outside of the body. Once fertilized, the embryologist carefully cultures the fertilized egg, now known as an embryo, for five to six days. A single high-quality embryo can be transferred to the uterus where a clinical pregnancy will occur if the embryo implants in the lining of the mother’s uterus.

The Step-by-Step Process of IVF Using Frozen Donor Eggs

Below are the step-by-step details of how the IVF process is done using frozen donor eggs.

Step 1:

Find an egg bank to search for your favorite donor. Cryos has hundreds of FREE donor profiles of extensively screened donors ready to view here. Once you’ve selected an egg donor, you will purchase and have the eggs shipped to your IVF clinic where the procedure will take place. Cryos will also give you the option to reserve your egg donor for later use should you desire siblings.

Step 2:

Once the donor eggs arrive at the clinic, they will be prepared for fertilization in the laboratory. The embryologist will carefully inject each egg with a single sperm to fertilize it. Within hours the sperm and eggs will combine to form embryos. The embryos are then cultured in an incubator under physiological conditions similar to a woman’s reproductive tract for five to six days.  When the embryo develops into a blastocyst, it is ready to be transferred or can be frozen for future use.

Step 3:

A single blastocyst will be transferred to the woman’s uterus using a catheter. If all goes well, a pregnancy can occur within a few days.
