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.
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 in fertility treatments, such as intra uterine insemination (IUI) or in vitro fertilization (IVF).
Sperm Freezing - What to Expect Patients are usually referred to the andrology laboratory for sperm cryopreservation by their doctor. At the first visit patients can ask questions and clarify anything they might want to know about sperm freezing and cryopreservation, such as storing the samples long term and billing, before the sample is collected and the semen storage agreement signed. Additionally, patients are always welcome to call with additional questions or clarifications.
