Area of Science:

  • Reproductive Medicine
  • Cryobiology
  • Andrology

Background:

  • Fertility preservation is crucial for men facing cancer treatment or other conditions impacting reproductive capacity.
  • Long-term cryopreservation of sperm offers a viable option for maintaining fertility potential.

Observation:

  • A case report details two successful pregnancies resulting from sperm cryopreserved for extended periods.
  • Sperm was stored for 21 and 28 years, respectively, before use.

Findings:

  • Artificial insemination using cryopreserved sperm resulted in two live births.
  • The longest successful sperm cryopreservation period reported to date is 28 years.

Implications:

  • Successful long-term semen storage provides significant benefits for family planning decisions in men with potential fertility impairment.
  • This underscores the efficacy of cryopreservation techniques for preserving reproductive potential over decades.
