Cryopreservation of spermatozoids

Purpose of the procedure

The cryopreservation of spermatozoids allows a man's fertility to be preserved during oncological or medical treatment or MAR. After microscopic examination of the concentration and mobility of spermatozoids in the ejaculate, the latter is frozen and then stored in liquid nitrogen at -196°C.

Collection

The sperm is collected in a sterile container by masturbation in rooms provided for this purpose in the laboratory.

Conditions

Abstinence for two to four days before the examination is recommended. The results of serology tests for HIV, HBV, HCV and syphilis must accompany the request for examination.

Contract

A contract is concluded for a period of one year and is tacitly renewed year by year. The maximum legal period of storage is five years, renewable once for another period of five years (total maximum duration: 10 years) in accordance with the Reproductive Medicine Act (RMA).

Sole exception: a longer period may be agreed with persons who, to ensure that they can have offspring, donate their sperm to be stored before a medical treatment or performance of an activity which may make them sterile or damage their gene pool.

Medical follow-up is provided by specialist doctors in the RMU.
