Egg & Embryo Freezing

What is embryo freezing?

Embryo freezing is also known as “cryopreservation” that involves storing embryos at a very low temperature so that they can be thawed and used later. Embryo freezing is often performed when there are more embryos than needed for a single in vitrofertilization (IVF) cycle. The extra embryos are saved and potentially used during later cycles. IVF success rates are generally lower with frozen embryos than with freshly fertilized embryos, but pregnancy rates with frozen embryos have been improving in recent years. The survival rate after thawing often depends on the quality of the embryos at the time of freezing.

Embryos can be frozen from one to five days after fertilization as long as they are of good quality. Typically, they are stored in batches of one or more depending on the number of embryos that are likely to be transferred into the woman’s uterus.

How are embryos frozen?

Embryo freezing often takes place when couples having in-vitro fertilization have extra embryos. However, you can choose to freeze embryos for the same reasons you freeze your eggs.

Embryo cryopreservation begins the same way as egg freezing: Using medication or your natural cycle to produce mature eggs and retrieving the eggs in a minimally invasive procedure. Once your doctor removes your eggs, they go to the onsite lab, where your partner or a donor’s sperm fertilizes them.

The exceptional team at New York Fertility Institute carefully monitors the eggs, verifies fertilization took place, and after 3-5 days of growth in the lab, the embryo can be frozen using vitrification.

Whether you freeze your eggs or embryos, you can depend on the high-quality care available at New York Fertility Institute — call or schedule an appointment online today.

Who are the best candidates for embryo freezing?

  • Couples undergoing IVF and have addition embryos
  • Medical treatments such as cancer that involve chemotherapy

When might I consider egg and embryo freezing?

Freezing your eggs or embryos safely preserves them so you can have children in the future. You may want to postpone having children until you’re older when you have a higher risk of infertility. Freezing and storing your eggs at a younger age prevents that problem.

Some women may face problems like a premature ovarian failure and want to save their available eggs. Egg and embryo freezing is often a necessary procedure for women with a cancer diagnosis. Chemotherapy and radiation treatments damage eggs and may cause premature menopause.

How are eggs frozen?

Egg freezing or oocyte cryopreservation begins by ensuring you have mature eggs to remove from your ovaries. Eggs normally mature during each monthly cycle, so you can wait through your natural cycle. However, this natural process typically produces only one mature egg.

As an option, you can take hormone medications that promote the maturation of multiple eggs. When your New York Fertility Institute provider retrieves numerous eggs, you have more healthy, viable eggs to preserve and a better chance for a successful pregnancy down the road.

When ultrasound and blood tests show the eggs are mature, your provider retrieves them from your ovaries using a high-quality aspiration needle that minimizes stress and discomfort and facilitates the collection of a maximum number of eggs.

They identify the healthiest eggs and freeze them using vitrification. Vitrification is a super-rapid process using quick dehydration and ultra-fast cooling that freezes the eggs by dropping thousands of degrees per minute.

Vitrification prevents the formation of ice crystals that could damage the eggs. When ready to use your eggs, the process is reversed, warming the eggs so sperm can fertilize them and implant in your uterus.
