    Area of Science:

    • Reproductive Medicine
    • Cryobiology

    Background:

    • Sperm cryopreservation is crucial for assisted reproductive technologies.
    • Established methods require optimization for simplicity and efficacy.

    Purpose of the Study:

    • To present a simple, effective method for human sperm cryopreservation.
    • To assess the viability and recovery rates of cryopreserved sperm.

    Main Methods:

    • Random collection of 15 human sperm samples.
    • Cryopreservation using liquid nitrogen storage.
    • Assessment of sperm recovery and viability post-thawing.

    Main Results:

    • Mean sperm recovery rate of 77% (range 62-91%).
    • No significant deterioration observed after 4 weeks of storage.
    • Successful application in donor insemination and fertility preservation.

    Conclusions:

    • The described method offers a simple and effective approach to human sperm cryopreservation.
    • Cryopreserved sperm maintains viability for assisted reproduction and fertility preservation.
    • The technique shows potential for adaptation to human embryo cryopreservation.
