Sperm cryopreservation is an important component of fertility management, and much of its successful application seems to affect the reproductive outcome of ART.

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.
