Different reasons for undergoing fertility treatment. Sometimes it's to ensure that they can start a family. One important component of fertility treatment is cryopreservation. This helps in donation and retrieval procedures and is an essential part of fertility treatments. Cryopreservation is the process of storing cells, tissue or any other substances that capable to damage by the chemical activity, under certain low degree of temperature for years. Because at low temperature any enzymatic activity or the chemical reaction cannot take place. Human gametes are also stores in liquid nitrogen at 196 degree Celsius.
Cryopreservation is done when there are more embryos or eggs than is needed for a single IVF cycle. The extra embryos or eggs are saved and used during later cycles. Egg and ovarian tissue storing or freezing are for fertility preservation in women. This technique is helpful in women with cancer, as chemotherapy and radiation treatment can often have a harmful effect on fertility. The sperms are also freezing in the case of male with cancer or infertility problem.
When storing eggs for a long time, cryopreservation is essential. For to preserve healthy eggs at an early age to start a family later in life, cryopreservation is used. This is effective because the chance of birth defects increases as a woman ages. Also it is essential for the egg donation process, which is one of the most effective treatments for infertility. An egg donor can provide eggs for a pair who select eggs in the future. This method is used store eggs for future.
Cryopreservation is essential for preserving sperm for future. Some men may want to undergo vasectomy but he like to start a family at some point later on. At that situation Cryopreservation will allow this option for to store sperms. Sperm donation is greatly assisted by cryopreservation.
If an IVF procedure is performed that involves donor eggs or sperm, cryopreservation will be used. Also if the couple want children after some years then they can use egg or sperm cryopreservation.
Cryopreservation is the freezing of sperms or eggs for use in future in vitro fertilization (IVF) cycles. In the time of IVF cycle, the fertilized eggs are transferred to incubators where they develop until ready for transfer to the uterus, usually 3-5 days. The number of mature embryos available for transfer different by patient, as does the number placed back in the uterus. So the maximum number of embryos that will be transferred to the uterus is limited, there will be often excess embryos. The excess embryo stores by Cryopreservation. The advantages to using frozen embryos in future IVF cycles is that the female not need have to undergo ovulation , which also reduces medication cost.
