How long does frozen sperm last?

August 10, 2019

So far, no limit has been established for how long human semen can be frozen when maintained and stored in appropriate liquid nitrogen storage. Cryogenic Laboratories has maintained cryopreserved human semen in storage for over 30 years and semen stored for 19 years has been used to achieve a pregnancy. Scientific literature shows conclusively that sperm motility, viability and morphology are not affected by proper long term cryopreservation.
