Fertility Preservation Treatment

Fertility preservation involves freezing and storing eggs, sperm or embryos for future use. The technique used to freeze gametes and embryos is called vitrification.

Egg Freezing Treatment

Freezing eggs is the procedure of choice in those that want to delay their child bearing due to social or medical reasons. The egg freezing procedure involves administering injections to stimulate the ovaries for around 12 days. Following this, the eggs are collected under sedation. The egg collection is a relatively non-invasive procedure, and carries minimal risks. On the day of egg collection the eggs are vitrified for future use.

The 1st birth from frozen eggs using vitrification was documented in 1999. This was followed by the HFEA permitting egg freezing treatment in the UK from 2000.

Since when is egg freezing treatment licensed in the UK?

The 1st birth from frozen eggs using vitrification was documented in 1999. This was followed by the HFEA permitting egg freezing treatment in the UK from 2000.

As per data published by UK’s fertility regulator The HFEA in Sept 2018, egg freezing cycles are on the rise and currently make up around 1.5% of all fertility treatment cycles carried out across the UK with majority of treatments taking place in London.

What to consider when deciding to freeze?

1. Your age at the time of starting treatment

As per the HFEA data, most women who froze their eggs in 2016 were over 35. The commonest age to freeze eggs was 38. However, the most common age women came back for fertility treatment to use their cryopreserved eggs was 40.

“There are many women freezing eggs into their 40s and even 50s. Given the scientific consensus around age-related fertility decline, it is not clear why patients of this age are freezing eggs and we would caution against this being a sensible option for this group of women.” HFEA

When should women be freezing their eggs?

‘Standard’ fresh IVF does not offer a solution to age-related fertility decline because it cannot reverse the egg degeneration that comes with getting older’. This is why the age a woman is when she freezes her eggs is so important. HFEA

In cases over the age of 35, we know there is a steep decline in fertility and this has an impact on both natural conception and IVF success rates. HFEA

The likelihood of a successful outcome following egg freezing is based on the age at the time of freezing one’s eggs. Hence, freezing eggs prior to early 30s would be the ideal time to have the best chance of a successful outcome in future. However, young women are likely to get pregnant spontaneously and are hence, are less likely to use their frozen eggs. The current 10-year legal limit on storage of frozen eggs means the frozen eggs are to be used within this period.

When one freezes later in life, the process may be more invasive and expensive due to the natural decline in fertility as more cycles may be needed to collect the desired number of eggs. The chances of treatment being successful reduces but one is more likely to use the frozen eggs.

2. Cost of treatment – how will you fund your treatment

3. Risks associated with the treatment – it is generally a safe treatment

4. Chances of success – The birth rate from frozen own eggs is 18% per treatment cycle

5. Risk of not using the frozen eggs - There is a chance that one may conceive spontaneously and hence, may not use the frozen eggs in the future

6. Risk to baby and mother - Currently 2000 babies worldwide have been born from cryopreserved eggs but long-term studies on safety for children born from this process are not yet available. Evidence to date, shows no differences between the use of vitrified or fresh eggs in the rates of obstetrical problems in pregnancy. There are no increased risks of chromosomal anomalies or significant physical or developmental deficits in the babies born.

“Egg freezing is emerging as a viable clinical technique to preserve women’s fertility, providing the eggs are frozen at a clinically optimum age, and the patient is aware of the risks and possibility of becoming pregnant naturally. The evidence suggests that if eggs are frozen below the age of 35, the chances of success using these frozen eggs is higher than the natural conception rate as the woman gets older.

The results of our analysis are supported by international evidence which suggests egg freezing is a successful and cost-effective method of preserving fertility.” HFEA

What are the steps involved?

Egg freezing involves the following steps:

Step 1 - Workup

a) Initial consultation

b) Fertility Fitness Tests

c) Follow up

Step 2 - Preparation

a) Complete consent forms

b) Attend a nurse consultation

c) Purchase of medication

Step 3 - Treatment

a) Ovarian stimulation

b) Egg collection

c) Freezing and storage

What is the success rate?

The most important factor that affects the success rates of egg freezing is the age of the women at the time of freezing. The age of thawing the eggs does not seem to significantly influence the outcome.

Birth rates from frozen own eggs are increasing but remain below fresh IVF treatment cycles at 18% per treatment cycle, HFEA data.

Sperm Freezing Treatment

Sperm can be frozen for future use either in artificial insemination or other fertility treatments, or be donated. You may want to consider freezing your sperm if you have a condition or are facing medical treatment for a condition that may affect your fertility, or you have a low sperm count or the quality of your sperm is deteriorating, or if you have difficulty producing a sample on the day of fertility treatment.

Embryo Freezing Treatment

After a cycle of IVF treatment, there may be a number of successfully fertilised embryos that you can store for your future use. The embryos need to be of good quality as poor quality embryos do not survive the freezing/defrosting process. Embryos can be frozen at various stages between the cleavage stage (day 2) to the blastocyst stage (day 5 or 6). They can be stored for up to ten years in the first instance.

A frozen embryo transfer gives you another chance of a pregnancy from the initial egg collection with a much reduced cost and without having to go through an egg collection again. You may be given some drugs to help build up the lining of the womb or you may have the embryos put back in natural cycle. You will have ultrasound scans to determine if you are ready for the transfer. At this time, the embryologist will warm the embryos. The embryo is transferred under ultrasound guidance using a soft catheter. Rarely, embryos may not survive the freezing/defrosting process.

Testicular Tissue Freezing | Surgical Sperm Retrieval

In men with no sperm in their semen e.g. those who have had a vasectomy and later decide they want children, or in those who cannot ejaculate, such as men with spinal cord injuries, it is necessary to extract sperm surgically in order to fertilise eggs during IVF. Sperm obtained using any of these procedures will usually have poor movement and will need to be directly injected into each egg. This process is known as intracytoplasmic sperm injection (ICSI).


The three different methods of sperm extraction are

-  Micro-epididymal sperm aspiration (MESA)

-  Percuateous epididymal sperm aspiration (PESA)

-  Micro-testicular sperm extraction (micro TESE)
