What are different methods of storage of sperm?
Sperm can be stored in a short or long term. Different short -term storage and transmission devices are used to process sperm in preparing for testing of fertilization procedures, but these processes are not suitable for storing samples for a longer period of time. At warm temperatures, sperm is rapidly degraded and long -term sperm storage requires the use of cryogenic technology.
For short -term successful storage of sperm, only the use of basic medical procedures. Samples are collected in sterile containers and these containers are quickly transported to laboratories or operating theaters, depending on whether they are to be used for testing or fertilization. In some rare cases, sperm may be processed and filtered during transmission to prevent the transmission of human immunodeficiency virus (HIV) or for some other medical purpose. Samples can be processed immediately or stored in chilled containers for a short time.
TRUE STORA SPERMIEGE requiresUse of sophisticated cryogenic technology. Extremely cold temperatures, which are usually achieved by liquid nitrogen as a cooling agent, are able to completely stop biological activity in cells and basically freeze in time. Long -term sperm storage uses this technology to freeze samples of viable sperm, which can then be thawed for years or even decades, later.
Careful monitoring of the frost process is necessary for proper storage of sperm. Incorrect freezing can lead to the formation of ice crystals and damage in cells, causing sperm to be than usable. Proper freezing ensures that the sperm is quickly cooled from normal temperatures to the temperature of the liquid nitrogen and then maintained at this temperature constantly.
One of the main purposes of sperm storage is to maintain samples for individuals who have to undergo medical procedures thm canOkodzit their fertility. Cancer treatment usually falls into this category, as well as some surgery. Sperm can also be stored by men who decide to undergo vasectomy to maintain the opportunity to have biological children later.
sperm can also be stored in sperm banks for the use of women who want to conceive but do not have fertile male partners. These storage devices usually offer anonymous sperm and sperm associated with specific acquaintances. Many sperm banks offer a chance to buy a sperm sample from a particular donor and then save most of the sample, while some part is used to treat fertilization.
