Cryopreservation consists of placing the semen sample in contact with a cryoprotectant – a substance that safeguards the integrity of the spermatozoa during the procedure. Preserved samples are kept in liquid nitrogen at extremely low temperature (-196ºC).
Semen samples may be preserved indefinitely, or until the male decides to complete his reproductive desire.
Hospital Ochoa’s sperm bank is periodically checked and interested parties will be notified every 12 months to renew their sample preservation.
It is advised that the male abstain from intercourse/masturbation for between 2 and 5 days prior to the production of the sample.
A series of tests must be carried out within 6 months prior to cryopreservation:
- CYTOMEGALOVIRUS IgG/IgM
- ANTI HIV ANTIBODIES
- HEPATITIS B MARKERS
- HEPATITIS C ANTIBODIES
- VDRL – TPHA
- Sars-cov-2 virus (PCR, IgG and IgM) (until further indication)
