Sperm freezing is the method of freezing and preserving sperm for future use. Men are able to freeze their sperm for use in their own future treatment or to donate to someone else’s reproduction health and infertility treatment. Donated sperm usually has to be quarantined for three or six months and screened for infections before it can be used by a recipient. The length of quarantine is dependent upon the type of screening tests that fertility center in Nepal/IVF Nepal carries out. Treatment with frozen sperm is just as successful as treatment using fresh sperm.
Sperm Cyropreservation is considered if
- One has a condition, or are facing medical treatment for a condition, that may affect your fertility.
- About to have a vasectomy and want sperm available in case the mind is changed about having (more) children.
- One has a low sperm count or the quality of your sperm is deteriorating.
- One has difficulty producing a sperm sample on the day of infertility treatment.
- One is at risk of injury or death (for example, you’re a member of the Armed Forces who is being deployed to a war zone).
For sperm freezing firstly, the sperm need to be tested for any infectious diseases like HIV and Hepatitis. This has no bearing on whether sperm can be freezed or not but is to ensure that affected sperm samples are stored separately to prevent contamination of other samples. Then need to give written, informed consent to sperm being stored and specify how long to be stored for. At the fertility center in Nepal, one will be asked to produce a fresh sample of sperm (if possible), which will be mixed with a special fluid (a cryoprotectant) to protect the sperm from damage during freezing. Before freezing, the sperm sample is usually divided between numbers of containers called straws. This means that not all the sperm needs to be thawed at once and can be used in multiple treatments. The samples are then cooled slowly and plunged into liquid nitrogen.
