The Human Fertilization and Embryology Authority (HFEA) recently decided to extend the duration of semen cryopreservation in Great Britain up to 55 years.

The time for which semen remains cryopreserved in liquid nitrogen does not affect the functional capacities of the spermatozoa, as at the state of ‘suspended animation’ all cellular functional activity is paused. This permits practically sperm preservation for long durations, even for decades.

According to Greek Law, the allowed time frame for semen cryopreservation is 5 years, with the permission to extend this period for another 5 years, following written informed consent.
