Sperm Cryopreservation

Cryopreservation enables spermatozoa sustain their viability for a long time in liquid nitrogen at -196 degrees Centigrage. This method enables the use of sperm in various assisted reproduction techniques (intrauterine insemination, IVF, micromanipulation) that are performed at a much later date after the sample-taking date, in order to achieve pregnancy.

Rapid developments in assisted reproduction have helped men suffering from cancer - or from diseases the treatment of which leads to infertility - have their biologically owned children.

Patients who will decide to have their sperm cryopreserved have to abstain from any sexual activity for at least 2 -5 days prior to sperm collection, while they must have completed AIDS and hepatitis A and B tests not later than three months prior to the artificial fertilisation attempt.

The benefits of cryopreservation include:

- Pregnancy possibilities in the future.

- Preservation of natural sperm that may be used at a later stage, when it will no longer be natural or when there will be no spermatozoa for various reasons, such as an operation or radiotherapy, chemotherapy or any other therapy that may impair semen fertility.

- Use of sperm (for intrauterine insemination or IVF) in more favourable conditions, when the collection of fresh sperm will not be possible.
