It is referred to as the technique or method where a sperm sample of men is stored and preserved for future use. It is also called sperm banking or Sperm cryopreservation.It is a means of preserving fertility for men undergoing the vasectomy or other treatment like chemotherapy, radiation therapy or surgery that may compromise their fertility.

Who requires Sperm cryopreservation?

Many medical treatments, including several cancer therapies, can damage sperm quality, which is why you may choose to freeze your sperm before receiving the medical treatment.

Although there is no information about how long frozen sperm can remain effective, sperm twenty years or older have been used successfully in pregnancies. Sperm freezing allows this sperm to be used in the future infertility treatments, such as intrauterine insemination (IUI) or in vitro fertilization (IVF) & ICSI.
Sperm Donation is also prevalent when the male partner in IVF treatment has the following complications:

  Nil  sperm count

  Less sperm count

  Poor sperm motility

  Poor sperm quality

  Any other unexplained issues.

Guidelines to be followed for Semen Cryopreservation: The collected semen sample is initially set in the warming square of 37 degree Celsius of temperature. This procedure melts the semen. At that point a solidifying operator is blended with the proportion of 1:1 to help the semen get by throughout the solidifying procedure. Water in the semen is uprooted by utilizing the cyroprotectants. This is carried out to anticipate cell harm in the put-away semen. At that point, the sample is put up in fluid nitrogen. It is preserved in vials and the name of the patient is marked on each vial,  as it is the property of that particular patient. Sperm cryopreservation is carried on for as many years as the patient want, once preserved can be further renewed as many years desired by the couple. The rate of survival of the semen varies to a great extent for different individuals.
