Background: Sperm cryopreservation is recommended to preserve male fertility for cancer patients or other medical conditions at risk of sperm decline. Whether motility and viability recovery rates vary depending on the requiring poorly known. We report here 24-year experience our semen bank. Methods: Motility were evaluated in 1973 collections from with various 67 donors, results related basal quality. Results: highly quality varied between non-cancer conditions, independently duration patient age. In samples a number below 2 × 106/mL, approximated zero. The highest found donor collections. Cut-off values least 1% motile spermatozoa established based initial Conclusions: Our indicate that occurrence any pathological condition resulted lower respect indicating intrinsic characteristics drive susceptibility cryodamage. Established cut-off can be useful counseling as well ART laboratories decide type procedure.
