Men who want to improve their chances of having healthy children later in life can benefit from freezing their semen. However, the process is more complex than simply producing a sample and sending it to the clinic for freezing.
Sperm samples must be collected, analyzed, and frozen properly, which requires the help of an experienced fertility clinic or sperm bank. This process is known as cryopreservation.
How Long Can Sperm Be Freezed?
Unlike eggs, which can become damaged over time, frozen sperm remain viable for years. In fact, sperm stored for 10 and even 20 years have resulted in successful pregnancies. The process of collecting, freezing and storing sperm is called sperm banking or cryopreservation. It is a great option for people who want to preserve their fertility due to age or health concerns, as well as for couples who have trouble producing semen naturally.
The first step in the sperm freezing process is a health check-up to ensure the patient is healthy enough to freeze his semen. There may also be other tests depending on the patient’s circumstances, including semen analysis and an antibody test to look for infertility causes.
Next, the semen is collected through masturbation, and then sent to a lab where it is tested again to ensure there are sufficient amounts of quality sperm. The sperm is then divided into multiple vials and frozen at a very low temperature of minus 196 degrees Celsius. These samples are then kept in storage tanks of liquid nitrogen, where they will be monitored until the patient is ready to use them again.
When a man is ready to use his frozen sperm, the sperm will be thawed and introduced into the woman’s body through intrauterine insemination or in vitro fertilization. While this doesn’t guarantee pregnancy, it is a very good way to try to achieve one, particularly in cases where the sperm production has been affected by cancer treatment.

Sperm can live for about five days after ejaculation, but they can also live for decades when frozen and stored properly. This is one of the reasons that sperm banking has become a popular preventive measure for men who are going to undergo cancer treatment that could affect their fertility. The process is called sperm cryopreservation and it’s usually covered by health insurance.
When people want to freeze their sperm, they typically visit a urologist and go through a series of health checks before producing a sample. They usually have to give blood so that they can be tested for sexually transmitted infections (STIs). They’re also asked to abstain from sex before the collection.
Once the sample is collected, an andrologist places it into vials that are then placed in a freezer filled with liquid nitrogen. “The sperm is then stored for future use,” explains urologist Amin Herati. “When needed, thawed sperm can be used for intrauterine insemination and in vitro fertilization.”
There are many reasons why people choose to freeze their sperm. Some may be concerned that they’re getting older and their fertility is declining. Others might be worried about infertility caused by cancer treatments such as chemotherapy. And still others might want to preserve their fertility in case they have to undergo treatments for serious diseases or conditions such as leukemia.
How Long Can Sperm Be Used After Freezing?
A person may choose to freeze sperm for a number of reasons. The decision to do so is a personal one, and depends on the person’s health and family planning goals. A urologist can help to make the best decision.
Frozen sperm can be used for intrauterine insemination (IUI), in vitro fertilization (IVF), and intracytoplasmic sperm injection (ICSI). The process is called sperm banking, which is also known as sperm cryopreservation. The goal is to preserve sperm quality until it’s needed for conception.
During the freezing process, the sperm sample is taken from a man’s body through masturbation. It’s then sent to a lab for a semen analysis. This tests the sperm for concentration, motility, and morphology to see if they’re healthy.
After the sperm is tested, it’s placed into small vials and frozen at a very low temperature of minus 196 degrees Celsius. These samples are then stored in a tank of liquid nitrogen, which is monitored and maintained by the lab.
Some people freeze sperm after cancer treatment, as the side effects of chemotherapy can cause fertility problems. Others freeze sperm because they’re concerned about their age and want to make sure they can still father children in the future. Even those who have already conceived children can benefit from freezing their sperm, as it gives them peace of mind that they can still achieve their family goals.
How Long Can Sperm Be Used After Thawing?
Sperm can be frozen for up to 55 years. However, after that time, a man will need to re-consent for storage. This can be done if they want to continue storing them or if their health needs change. For example, if they need to start hormone therapy or undergo surgery that can affect fertility.
During freezing, a man’s semen is cooled to extremely sub zero temperatures. This causes the sperm cells to freeze and enter a state of suspended animation. At that point, they are no longer metabolizing or depleting their energy reserves. They also cannot be attacked by bacteria or any other microbes that can damage them.
Once thawed, the sperm can be used to attempt a natural conception or through artificial insemination. However, the sperm must be washed and tested for mobility before being used in either of these methods. Those who choose to use frozen sperm should work with a fertility clinic that regularly works with this type of sample.
The process for freezing sperm varies a little from clinic to clinic, but there are some general steps that most doctors will take. The first step will be to test the men for any infectious diseases like HIV or hepatitis. They will then have to give their written consent for the sperm to be stored and specify how long they want it to be kept.
