Sperm Freezing is becoming increasingly popular for men who are concerned about the decline in the health of their sperm and wish to store sperm for use in future treatments, if required, when they are ready to start or expand a family.

Freezing sperm is typically a straightforward process. Sperm freezing involves collecting, preparing, and freezing sperm for potential future use in fertility treatment. Before freezing, a semen analysis is performed first to assess the quality and quantity of the sperm, alongside screening tests required for storage.
If the results suggest there is room for improvement, we may recommend lifestyle changes and repeat the test at a later date to optimise sperm quality. You are advised to avoid ejaculation for about two to five days before providing a semen sample at the clinic.
Once the sample has been produced, our embryology team carefully assesses and prepares it within the laboratory. A specialised cryoprotective solution is added to protect the sperm during freezing and thawing, before the sample is gradually cooled and stored in liquid nitrogen cryostorage systems.
Under current UK legislation, sperm can usually be stored for up to 55 years, provided consent is renewed at the required intervals. Frozen sperm can later be thawed for use in fertility treatments such as IUI, IVF, or ICSI.
People choose sperm freezing for many different personal and medical reasons. Sperm freezing may be appropriate if:
What are my chances of success with sperm freezing?
Fertility treatment using frozen sperm can achieve success rates comparable to treatment using fresh sperm in many situations. However, although sperm freezing is considered very safe and effective, not all sperm cells will survive the freezing and thawing process. Success rates also depend on factors such as the quality of the original sample, the type of fertility treatment used, and overall reproductive health.
How long can frozen sperm be stored?
Under current UK legislation, sperm can usually be stored for up to 55 years, provided consent is renewed at the required intervals. Our team will contact you when consent renewal is needed and guide you through the process.
How many sperm samples should I freeze?
The number of samples recommended varies depending on sperm quality, future family plans, and the type of fertility treatment that may be required later. In some situations, storing multiple samples may help maximise future reproductive options.
What happens when I want to use my frozen sperm?
When you are ready to use your frozen sperm, the sample is carefully thawed and prepared within the embryology laboratory. Depending on sperm quality and your fertility treatment plan, frozen sperm can later be used for treatments such as IUI, IVF, or ICSI.
Can frozen sperm be used with donor eggs or surrogacy?
Yes. Frozen sperm may be used as part of a range of fertility treatment pathways, including treatment with donor eggs, IVF, or surrogacy arrangements where appropriate.
Will freezing damage my sperm?
Some sperm cells do not survive the freezing and thawing process, which is expected with cryopreservation. However, modern freezing techniques are highly effective, and many samples retain good viability after thawing.
Do I need infectious disease screening before sperm freezing?
Yes. Screening tests are required before long-term sperm storage in accordance with UK fertility regulations. Our team will explain which tests are needed before treatment begins.
