Sperm cryopreservation

Theoretically, sperm can stay frozen indefinitely. A pregnancy has been reported in the literature using sperm which had been frozen for 20 years.

Sperm should be cryopreserved:

  • When there is a risk of reproductive ability loss (testis removal, chemotherapy, radiotherapy.)
  • When the male partner will be absent on the day of oocyte retrieval.
  • In cases of surgical sperm recovery.
  • In cases of sperm recovery using electroejaculation.
  • In cases of ejaculation problems.
  • In cases of progressively declining sperm quality.
  • Before sterilization by vasectomy.
