Eggs can be frozen for a long time and do not affect the quality much after defrosting. However, women should consider the time of pregnancy, not too old because it can affect health during pregnancy as well as time spent with children.
To date, no studies have shown an increased risk of birth defects for children born from frozen eggs.
Sperm freezing is intended to perform infertility treatment or ensure future fertility for men. Sperm storage is performed through surgery such as sperm extraction or aspiration from the testicles and sperm aspiration from the epididymis through the skin. Sperm will be tested for genetic potential and quality before being frozen. When needed, the sperm will be thawed and fertilized through sperm injection into the uterus, also known as artificial insemination.
Fertility preservation is a method of storing your healthy cells until you decide to conceive. A better understanding is the freezing of oocytes, ovarian or sperm tissue, testicular tissue, and freezing of embryos to reserve for future use. This process gives men and women the opportunity to conceive their own genes in the future with healthy children.
Scientifically, there is no limit to how long sperm can be stored in a frozen state, as long as the sperm is properly stored inside liquid nitrogen and it is a high-quality sample to begin with.
Frozen sperm does not have an exact end date. Today, with the development of advanced cryopreservation techniques, the health and integrity of the sperm maintained during this process is more enhanced. In many cases, sperm is stored for over 20 years, the amount of time stored does not affect the success rate.
This is a very safe method. Currently, there are no known risks to patients or children when using frozen sperm. However, not all sperm survive the freezing and thawing process.
The technique of cryopreservation of sperm is quite simple, but during the implementation process it can affect sperm quality, especially during the storage and thawing stages, because at this time there is a sudden change in temperature, causing Heat shock can easily affect the viability of sperm.
Before deciding to store sperm, you need to be examined by a doctor and carefully advise whether your case requires freezing or not. This will optimize treatment costs.
People who die within 3 hours can still freeze sperm, but the sooner the sample is taken, the better the sperm quality.
