Egg Freezing in Texas

If you’re concerned about your future fertility, egg freezing is an invaluable way to add time to your biological clock. The process involves stimulating the ovaries to incite egg production, removing mature eggs, rapidly freezing them with vitrification technology, and storing them at -196°C. Our fertility specialists can help you determine where you are on your fertility journey and if now is the time to freeze your eggs.

Is Egg Freezing Right for You?

Our fertility specialists will work closely with you to determine whether egg freezing is your best fertility option. We often recommend egg freezing for the following reasons:

You are planning to undergo chemotherapy or radiation therapies.

You have a family history of premature menopause and may want to take cautionary measures.

If you struggle with benign gynecological diseases, such as endometriosis or ovarian cysts, which may require surgical removal of reproductive organs.

You’d like to delay having a child.

You are undergoing another treatment like IVF and would like to freeze extra fertilized embryos for future use.

How Egg Freezing Works

Ultra-rapid freezing technology called vitrification freezes eggs rapidly, producing a 90% egg survival rate and +50% pregnancy rates in some groups of patients. The entire egg freezing process takes about 4-6 weeks from start to finish.


Ovarian Reserve Testing

First, we will evaluate your ovarian reserve. Normal egg reserves usually have an antral follicle count of +12 and an AMH level of +1.5 ng/ml.


Birth Control

You will take birth control pills (BCP) during the pre-stimulation cycle to rest the ovaries and learn how to inject medications. This period can last 2-3 weeks. Patients with low egg reserve will not use BCP.


Ovarian Stimulation

For 10-12 days, you will use injectable medications to stimulate your ovaries while we closely monitor you with sonograms and hormone checks. The stimulation protocol depends on how many eggs your ovaries can produce in a cycle and how many children you desire in the future.


Egg Retrieval

We will perform the egg retrieval process while you are under IV anesthesia for about 20 minutes.


Egg Freezing

In the laboratory, eggs will be assessed for maturity. The mature eggs will be immersed in a cryoprotectant solution to remove water from the egg cells (dehydration). The ‘dehydrated’ eggs are put into specialized straws, flash frozen in milliseconds, and stored in a liquid nitrogen tank. Immature eggs will be incubated and observed for signs of maturity for later freezing.

How We Use Your Frozen Eggs

When you are ready to use your frozen eggs, you’ll likely go through these steps:

Lily Icon

Two Weeks Before

Prepare your endometrium for the embryos. Estrogen will be used to grow the endometrium. Then we’ll add progesterone to mature the uterine lining for implantation.

Lily Icon

One Day Before

Eggs will be thawed and injected with sperm (ICSI) to optimize fertilization.

Lily Icon

Day 1

Our fertility specialists will check the status of your egg’s fertilization to make sure everything is good to go.

Lily Icon

Day 3-5

Embryo culture progress will be checked, and we’ll update you on the status of your embryos.

Lily Icon

Day 5

Embryo transfer will be performed during the advanced (blastocyst) stage of development. Up to two embryos can be transferred. To facilitate implantation, we may create a small hole in the embryo’s zona through a process called laser hatching.

Day 15

You’ll take a pregnancy test (and hopefully see a positive result!)



  • How many eggs should I freeze? And for how long?

    We recommend that you freeze about 10 mature eggs for every pregnancy you plan to achieve. Assuming a 90% egg survival rate, thawing 10 eggs would result in 9 viable eggs. With an average fertilization rate with ICSI of 70%, about 5-6 eggs would fertilize to eventually provide 2 blastocysts for transfer or freeze on day 5 of culture.

    There is very limited data on long term storage of eggs. However, one study showed no difference in egg survival rate, embryo quality, pregnancy rate or live birth rate in eggs frozen up to 4 years compared to earlier thaws.

  • What is the egg retrieval process like?

    Eggs are aspirated from both ovaries using a thin needle that is on top of a vaginal ultrasound probe. You will not feel or remember anything during the retrieval procedure, and you’ll wake up instantly after the procedure is completed. You will rest for about 30 minutes in a recovery room before being discharged. 

    Due to the effects of anesthesia, you will need to have someone drive you home after the procedure. You should be able to return to normal activity later that day. Mild cramping or discomfort may occur and can be treated by medications as needed. Over the next few days, you may feel mild abdominal discomfort or bloating sensations.

  • How safe is egg freezing?

    Since 1986 there have been more than 2,000 live births from frozen eggs worldwide. Studies on the safety of egg cryopreservation have revealed the following:

    1. There was no difference in chromosomal abnormalities in embryos from frozen eggs compared to those created from fresh eggs.
    2. A review of 900 births from slow-freeze eggs revealed no increased risks of birth defects compared to the general population.
    3. A review of 200 babies born from vitrified eggs showed no difference in birth defect rates compared to those conceived after fresh IVF.
    4. Overall, of the babies born from frozen eggs, only 1.3% had birth defects–a rate not significantly different from naturally conceived infants.
  • How successful is egg freezing?

    The success in producing a baby from egg freezing depends on the age of the woman at the time her eggs are frozen. The risk of producing abnormal eggs increases significantly after age 35.

    Studies have revealed an egg survival rate of 80-90% after being thawed and a fertilization rate of 70-80%, which is about the same as in fresh eggs.
