Egg or embryo freezing: Fertility preservation information

The Agora Clinic is a fertility centre. One of the treatment options we offer is fertility preservation for patients undergoing treatment for cancer. This includes egg and embryo freezing.

You have been given this leaflet because you are soon to undergo cancer treatment which may affect your fertility. This leaflet explains what fertility preservation is, why you may need it and how to proceed. Hopefully you will find all the information you need here and on our website Fertility preservation before cancer treatment.

We want to provide you with the guidance and support you need to help you make the best decisions about your future parenting options. We understand how overwhelming this time is for you, so we are here to make your journey as easy as possible. If you have any further questions or concerns, please call us on 01273 229410 where our staff can help you.

Why is it important to discuss fertility before starting cancer treatment?

To be told that you have cancer and that the treatment for it may affect your fertility and could make you permanently infertile, can be very difficult. For some people, the threat of losing their fertility can be as difficult to accept as the cancer diagnosis. For others, beating the cancer is their main priority. Each person will feel differently so there is no right or wrong way to feel and react. We believe it is vitally important that at this stage you are fully informed about your options for fertility preservation so you can make the decision that is best for you. Don’t be afraid to ask us questions as that is why we are here. Everyone has their own way of coping with difficult situations and some people also find it helpful to discuss how they are feeling with their partner, a close friend, or relative. It is also possible to discuss how you are feeling with one of our specialist fertility counsellors who works with the Agora.

How can I preserve my fertility?

Eggs or embryos (eggs that have been fertilised with sperm) may be stored at the Agora Clinic as a backup for fertility treatment in the future if you need to have chemotherapy, radiotherapy or surgery that could make you infertile. It is important that samples are frozen before you start any of these treatments if you are advised that is a risk that your eggs or egg reserve may be affected by the treatment.

The NHS will fund fertility preservation and the storage of your eggs or embryos if you fulfil the eligibility criteria for funding. Otherwise you can have this treatment privately.

How can cancer treatment affect fertility?

Treatments for cancer such as surgery to the pelvic area (including the testicles and prostrate), chemotherapy and radiotherapy can all affect a sperm health in different ways. Some cancer treatments can:

  • Damage to or removal of the ovaries which will reduce or stop the production of eggs (temporarily or permanently) leading to low ovarian reserve
  • Reduce the production of female hormones oestrogen and progesterone, which can influence your sex drive and energy and lead to menopausal symptoms
  • Damage to or removal of the uterus, fallopian tubes or cervix (neck of the womb), reducing the ability to carry a pregnancy in the future (which may lead to you needing surrogacy).

It can be difficult to predict whether your fertility will be affected by cancer treatment or whether it will return to normal once the treatment has finished. Although some treatments for cancer such as chemotherapy may reduce your ability to produce eggs for a time, it may still be possible to produce healthy eggs once treatment has ended. The chances of fertility returning to normal decreases in women as they get older, particularly if chemotherapy is started over the age of 35. This is why storing eggs or embryos can be a sensible back-up plan to preserve your fertility if you think you would like to have a child in the future.

Women with a partner who are concerned that they may become infertile are advised to discuss storing embryos (fertilised eggs) for future use. This requires an IVF approach where hormone injections are used to stimulate the ovaries to produce more eggs than normal over a 2 week period. The eggs are then collected and fertilised using sperm from a partner (or donor). Embryos are then formed and can be stored safely and successfully for many years. For women without a partner egg freezing is the best option. Once the eggs are collected, they are frozen straight away (before being fertilised).

Egg or Embryo Freezing

At the Agora, we offer both egg and embryo freezing. It is an important consideration to decide which would be better for you. Women who wish to use their partner’s sperm to create embryos must have had a careful discussion with their partner as it is possible in the future for a man to withdraw his consent for use of embryos using his sperm. It is therefore vital that both partners understand the personal and legal implications of freezing embryos.

It is also possible for single women to freeze embryos using donor sperm. This is a matter which should be discussed carefully when you have your doctor’s consultation. In recent years, rapid-freeze techniques called vitrification have made the process of egg freezing and thawing far more successful and this is now a viable option for women who are single or who want to keep their options open even if they are with a partner at the time of their cancer diagnosis. When you are ready to conceive after treatment, the eggs can be thawed and fertilised with either sperm for your partner or using a sperm donor and the fertilised egg or embryo can be transferred into your womb.

If you want to talk to someone about preserving your fertility, your cancer (oncology) team will refer you to the Agora. This should happen quickly so that any delay to your cancer treatment is minimised. We ensure that all cancer patients are fast-tracked and seen within 24-48 hours of referral.
