How do we preserve sperm?
For the preservation of sperm, the method of cryopreservation is used. They are stored frozen in liquid nitrogen at a temperature of -196 °C in special containers. The previously used slow freezing method has now been replaced by vitrification, which involves an immediate rapid temperature drop. Unlike slow freezing, no ice crystals are formed that could damage the cells.
How long can we store the sperm?
Sperm frozen using the vitrification method can be preserved for several decades. Once the right time comes for you, they can be easily thawed and used.
How is sperm retrieved?
Sperm is collected after two to three days of sexual abstinence. The collection is performed in the collection room by masturbating into a sterile container, and the sample must be personally delivered by the man to whom it belongs. If collecting sperm in the collection room is not suitable for you, the presence of your partner may be allowed, or with prior arrangement, you can bring the sample from home in a designated container provided by the clinic.
