Egg Freezing Colorado & South Dakota

freezing eggs

Egg freezing is a breakthrough technology that allows women to freeze and store their eggs until a pregnancy is desired, at which time the eggs are thawed, fertilized and transferred to the uterus as embryos. Dr. Smith at Rocky Mountain Fertility Center provides individuals with the option of egg freezing at both Colorado and South Dakota facilities.

Not until recently, has a successful technique for freezing eggs been developed.  This new technique will help women facing infertility due to chemotherapy, women whose egg supply may run out as they age, in addition to couples who have an ethical dilemma with embryo freezing, save eggs for future fertility.

Egg Freezing Process

  • egg freezing colorado | south dakota It takes approximately six to eight weeks to complete an egg freezing cycle. Essentially women who desire to freeze their eggs have to undergo IVF.
  • A few weeks of birth control pills to rest the ovaries.
  • Followed by about 2 weeks of hormone shots to stimulate the ovaries to develop multiple eggs.
  • When the eggs have developed to the correct size an egg retrieval to obtain the eggs to be frozen will occur.
  • Immediately the following retrieval, the eggs are frozen.
  • In the future. when an embryo transfer is desired, the eggs are thawed, injected with a single sperm to achieve fertilization, and transferred to the uterus.

Women who desire to freeze their eggs should set up a new patient appointment.  Your medical history will be reviewed and egg quality will be checked to see if you will be a good candidate.  We do not freeze eggs on women > 40 years of age.

freezing eggs FAQs


1.  Individuals faced with the prospect of losing ovarian function either surgically, through chemotherapy or radiation exposure may benefit from the cryopreservation of eggs. There may be medical contraindications for some individuals to participate in the cryopreservation program. Medical consultation with your oncologist or surgeon may be required.

2. Couples undergoing in vitro fertilization who are morally or ethically opposed to the cryopreservation of embryos.

3. Individuals who anticipate delaying childbearing into their late thirties. Certainly, we know that many individuals after age 37 will have severely diminished fertility due to remaining egg number and quality.

What are the egg freezing success rates?

    • For women, under 35 years about 12 mature eggs will be required to obtain a 50% chance of a live birth.
    • For women over 36 years of age, 16 eggs will be needed to have a good chance of success.
    • Egg quality is primarily a function of age but does relate to ovarian reserve. Egg quality in general declines with age.  Because of concerns over egg quality, we do not offer egg freezing to patients older than 40.

    Because egg quality will vary from individual to individual, it is not possible to assert for any particular individual their chances for a successful pregnancy from a given number of eggs. More accurate assessment of ovarian reserve can be obtained through hormonal testing. The tests that we currently recommend are the anti-mullerian hormone,  follicle stimulating hormone, and estradiol hormone levels.

Is it safe?

To date, approximately 2000 babies have been born worldwide from frozen eggs. Among these births, the rate of birth defects and chromosomal defects has been no higher than in the general population. Additionally, genetic screening of embryos is available.
