What is a cryoconzervation of sperm?
Cryokonzervation of sperm is a method of maintaining sperm. The sperm receives frost treatment that prevents degradation and then thaws if necessary. It is a common technique in cases where one wishes to save sperm before treatment of cancer or where couples require further help in pregnancy of the child.
For a long time as the 1950s, scientists used cryoconzervation of sperm as part of the treatment of human fertility. When it is correctly frozen, the sperm can freeze at the time of their lives and remain viable for years. Liquid nitrogen is a method of freezing for sperm cryoconzerva. For example, chemotherapeutic drugs or radiation as part of the cancer treatment program may adversely affect the quality or amount of sperm produced. Therefore, a man may want to create a supply of frozen sperm quality to use it as part of the future pregnancy with his partner.
Fertility problems can also affect sperm quality and men with a low creepM sperm can be able to build a decent supply under a cryogenic preservation for future use in fertility treatment. Sperm supplies of quality quality, although a man has no problem with fertility alone, can also be practical for use when a woman has a steam problem with fertility. Eggs can also be frozen in the same way.
Every sperm sample is mixed with a substance such as glycerol that protects the sperm from low temperature damage. The sperm is contained in small bottles and maintained in the freezer vessel, which is full of liquid nitrogen. This liquid nitrogen keeps the sperm frozen to a very low temperature. Low temperatures, such as -320 degrees Fahrenheit (about -196 degrees Celsius), which achieve liquid nitrogen, keep the sperm healthier longer than higher temperatures. The risks include the possibility that the freezer can disintegrate.
When sperm is required to treat fertility, technicI remove the bottle and pull the sperm out. About half of the sperm will usually not survive the process of cryoconzervation. Different types of fertility treatments can be performance with lively, thawed semen. These range from the simple intrauterine insemination that a woman can perform, to a more complicated procedure, such as in vitro fertilization, where eggs are first removed from a woman and then injection of one particular sperm into Petri's bowl.
