Egg Freezing

Krishna IVF Clinic is a multilingual, state-of-the-art IVF Lab and Fertility Clinic that offers personalised care with latest technology needed to manage infertility & reproductive disorders.

  • Egg freezing is a process that involves stimulation of the ovaries, than oocytes retrieved by ultrasound and freezing and storage of eggs.
  • Vitrification is a process by which egg freezing is done, it has better survival post thaw and improved pregnancy rates.
  • Egg freezing is being done from 1990s for fertility preservation in women with cancer. Social freezing is offered to women under 37 Years age who want to preserve fertility for a later date.
  • Social freezing followed by IVF and embryo transfer is advantageous to women. Who want to become pregnant at an advanced age or in the future.
  • It is important that women understand that there are no guaranties that egg freezing will enable them to have a baby later in life.
  • Egg freezing give women freedom and time to choose, when they want to have a baby.

Treatment Options: our treatment options may include IVF, in vitro maturation (IVM) or, if the sperm you are using is not of optimum quality, ICSI.

Chance of having a baby with frozen eggs : Eggs do not respond as well as embryos to freezing, and generally the resulting success rate is not as high, although this will vary from clinic to clinic. However, vitrification (a new method for egg storage) has recently been shown to improve the chance of eggs surviving the freeze-thaw process and therefore increase the success rate

Risks of freezing eggs : The usual risks of using fertility drugs apply to the fertility treatment involved. Egg freezing is still a relatively new technique and not all eggs will survive the freezing and thawing process or become fertilised. It is important that you take into consideration the risks of this procedure and the likelihood of your eggs surviving the process when deciding whether to store your eggs for future use.

Options for girls or women having cancer treatment: Some women about to have cancer treatment are able to freeze their eggs for later use. For those who are not able to do this, freezing ovarian tissue may be an option. This involves either taking a whole ovary or small pieces of tissue from an ovary, containing eggs, which is then frozen and stored. Ovarian tissue freezing is in the very early stages of clinical use but it may be a suitable option for girls or some women wishing to preserve their fertility before undergoing cancer treatment. It may be suitable for girls who have not reached puberty yet and do not therefore have any mature eggs to collect from their ovaries for egg freezing. It may also be suitable for women who do not have enough time to undergo an egg collection before their cancer treatment commences.

The use of frozen eggs in treatment is a relatively new development.

Vitrification (a new method for egg storage) has recently been shown to improve the chance of eggs surviving the freeze-thaw process and therefore increase the success rate. To help boost egg production, fertility drugs are used to stimulate the ovaries to produce follicles (which contain the eggs). The developing follicles are monitored and when they are large enough, they are carefully emptied to collect the eggs that they have produced. They are collected while the patient is under sedation or general anaesthetic. To freeze the eggs, they are placed in storage in liquid nitrogen.

Storing your eggs may enable you to use them for treatment in the future.

You may want to discuss freezing your eggs with your clinic if:

  • you have a condition, or are facing medical treatment for a condition, that may affect your fertility (for example if you are undergoing chemotherapy for cancer)
  • you are concerned about your fertility declining as you get older and are not currently in a position to have a child
  • you are at risk of injury or death (eg, you’re a member of the Armed Forces who is being deployed to a war zone)

The procedure for freezing eggs is as follows:

  1. Before you agree to the freezing and storage of your eggs, your clinician will explain the process involved, including the risks. Your clinic should also offer you the opportunity to discuss your feelings and any concerns with a specialist counsellor.
  2. You will be screened for infectious diseases, including HIV and hepatitis B and C.
  3. You will need to give written consent for your eggs to be stored.
  4. Eggs are collected using the same procedure as for conventional IVF.
  5. Cryoprotectant (freezing solution) is added to protect the eggs when they are frozen.
  6. The eggs are frozen either by cooling them slowly or by vitrification (fast freezing and then stored in tanks of liquid nitrogen).

The consent forms allow you to specify:

  • that you consent to your eggs being stored then used in your treatment
  • how long you want the eggs to be stored (the standard period is 10 years)
  • what should happen to your eggs if you were to die or become unable to make decisions for yourself
  • whether the eggs are to be used for your own treatment only, or whether they can be donated for someone else’s treatment, or used for research or training
  • any other conditions you may have for the use of your eggs.
