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.
Egg Donation and Cryopreservation
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.
Sperm Donation and Cryopreservation
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.
IVF and 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.
