Cryopreservation

Sperm freezing to preserve fertility – modern solutions at Kinderwunschzentrum Dresden

Cryopreservation – the freezing of sperm offers men the opportunity to secure their fertility for the future. The reasons may be medical, such as upcoming chemotherapy or surgery, or personal, such as delaying fatherhood until a later stage of life. At Kinderwunschzentrum Dresden, we use modern techniques to ensure safe and reliable sperm storage. This article explains the process, costs, medical background, as well as chances and limitations of cryopreservation.

What is cryopreservation?

Definition

Cryopreservation is the freezing and storage of sperm in liquid nitrogen at –196 °C. At this temperature, all biological activity stops, and sperm can remain viable for decades.

When is sperm cryopreservation recommended?

• Before chemotherapy, radiotherapy, or testicular surgery
• In cases of reduced sperm quality (as a backup for fertility treatment)
• Prior to sterilisation if future parenthood is not excluded
• For social reasons, when fatherhood is planned later

How does cryopreservation work?

Preparation

• Initial consultation at Kinderwunschzentrum Dresden
• Semen analysis to assess quality
• Mandatory infectious disease screening (e.g., HIV, hepatitis)

Sperm collection

• Typically through masturbation at the clinic
• In specific cases, surgical retrieval (e.g., TESE) is required

Freezing process

• Semen sample divided into small portions
• Cryoprotectants are added to protect cells during freezing
• Storage in liquid nitrogen at –196 °C

Cryopreservation costs

How much does sperm freezing cost?

• Initial collection, analysis, and freezing: 250 euros including 3 months of storage
• Monthly storage fee: 65 euros starting from the fourth month

Insurance coverage

Statutory health insurance in Germany generally covers the costs when there is a clear medical indication, such as before fertility-damaging treatments including planned chemotherapy, radiation therapy involving the gonadal region, or testicular surgery. Private health insurance may provide partial coverage depending on the individual policy.

Chances and success rates

• Over 90% of sperm survive the freezing and thawing process.
• Frozen sperm can later be used for insemination, IVF, or ICSI.
• Pregnancy rates are similar to those achieved with fresh sperm.

Risks and limitations

• Small risk of reduced sperm motility after thawing
• Sperm quality before freezing influences subsequent success
• No guarantee of pregnancy – success also depends on the partner’s fertility factors

Cryopreservation in Dresden – your advantages

• Years of experience in sperm, egg, and embryo cryopreservation
• Comprehensive support from consultation to later use of samples
