Sperm Freezing and Storage

Sperm Freezing 300x150Sperm freezing and storage is the procedure whereby sperm cells are frozen to preserve them for future use. Sperm cells have been frozen and thawed successfully for more than 40 years. By using special technology and then keeping sperm in liquid nitrogen at minus 196C, it can be stored for many years while maintaining a reasonable quality.


Why would I want to freeze sperm?

Unfortunately, life is unpredictable. There are many situations that could interfere with your future fertility. These may include:

  • Chemotherapy or radiation therapy.
  • Certain types of pelvic or testicular surgery.
  • Vasectomy.
  • High-risk occupations or sports.
  • Diabetes, which may cause erectile difficulty.
  • Being away from home on day of assisted reproductive treatment.

How do I arrange sperm freezing?

Please ask your GP or specialist for a referral form to see one of our specialists at City Fertility Centre.

It is preferable if, before your first appointment,  blood tests for hepatitis B, hepatitis C and HIV are arranged. We routinely screen for these infections because they may be transmitted through the semen, and to minimise the risk of contamination during storage.

Once you receive your blood test results, please contact us to arrange, to book a time, to produce the sample at our clinic.  At this time you will need to sign consent forms for the freezing and storage of sperm, which lasts for up to 10 years at a time.

How many sperm samples do I freeze?

Everyone’s situation is different. Most men freeze between two and five samples. Some choose to freeze many more. Often, the time interval before surgery, chemotherapy or radiation therapy will be the deciding factor.

We recommend abstaining from intercourse and ejaculation for at least two days but not longer than five days before the first sample, and for about two days between the samples.

Sperm storage

Scientifically, there is no limit to the length of time that sperm can be stored in a frozen state. However, the standard storage period for sperm is 10 years. This term can be exceeded only in certain circumstances. City Fertility Centre will explain whether you can do this, and for how long you may be able to store your sperm.

Damage can occur to the sperm during freezing and thawing, not while it is frozen. The amount of time in storage does not influence the success rate.

If you decide to freeze and store your sperm with City Fertility Centre, you must update us about any address changes.

What happens if I want to thaw and use the samples?

Please inform your City Fertility Centre specialist that you wish to utilise your frozen sperm sample.

There are several treatment options available for you and your partner to achieve a pregnancy. The type of treatment recommended can vary depending on the number and quality of sperm available. As part of this process, your partner may also require some basic fertility investigations.

Frozen sperm can be used for Intra-Uterine Insemination (IUI) if its post-thaw quality is good enough. If the sperm quality is reduced due to illness or other factors, it might be necessary to undertake In Vitro Fertilisation (IVF) and Intracytoplasmic Sperm Injection (ICSI), a specialised form of IVF whereby individual sperm are injected directly into the eggs.

Could there be a problem with the quality of sperm?

Yes, there may be a problem with the number and quality of the sperm, especially in men who are about to undergo cancer treatment. Their underlying illness may have caused a reduction in the sperm count or in their motility (movement). In such situations, it may be advisable to freeze even more specimens if time and treatment permit.

Are there any problems with the children produced by the use of frozen/thawed sperm?

Research has shown no difference in the rates of abnormalities or birth defects among children conceived with fresh versus frozen sperm. However, there are some theoretical concerns that chemotherapy drugs may have unknown effects on the sperm or the offspring. If possible, it is best to freeze the specimens before chemotherapy begins.

What options are available if I choose not to keep my sperm cryopreserved?

The following options are available if you decide to no longer keep your sperm cryopreserved:

  • Removal from cryopreservation (thawed and discarded).
  • Donation for scientific training.

Whatever option you decide on, signed consent forms are required. Please contact the fertility coordinators to discuss these options.
