Abstract
Six donor semen samples were evaluated after 28 years cryopreservation in liquid nitrogen. The results showed that the samples retained good postthaw motility recovery and normal levels of binding to the human zona pellucida and that four of the five samples tested also gave normal levels of zona-induced acrosome reaction. In conclusion, human sperm can survive very long-term storage, which is pertinent information for clinicians referring boys and young men for sperm banking before chemotherapy.
