Cryopreservation of Semen
Sperm cryopreservation or sperm freezing is a method for men to preserve their sperm and store it in a bank for future use.
Many medical treatments, including several cancer therapies, can damage sperm quality, which is why it is advisable to freeze sperm before receiving the medical treatment.
Sometimes the partner is away for some reasons for quite a long time or may not come on particular days in treatment cycles. In these situations semen freezing and subsequent use is very useful.
Sometimes the partner is unable to produce semen sample on the day of oocyte retrieval. In this situation it is always better to have a backup of frozen semen sample.
Sperms retrieved from epididymus or testis should also be frozen for future use.
