The male reproductive system consists of the testes (say “tes-teez”), a system of seminal vesicles and ducts through which sperm pass, the prostate gland, and the penis. Sperm cells are produced in the testes. They mature in the epididymis, a tightly coiled tube that resides on the backside of each testicle. From there, sperm travel through a series of tubes to the seminal vesicles, where they mature and are mixed with fluids that help them survive outside the body. The prostate gland adds secretions to this mixture. Finally, sperm pass through the penis and mix with additional fluids from the bulbourethral glands to form semen just before ejaculation.

What is Sperm?

Sperm is the male reproductive cell. It is a type of gamete which fertilizes an egg to form a new individual. Sperm is produced in the testicles and stored in the epididymis.

The Importance of Sperm

The average ejaculation contains between 40 million and 150 million sperm. You need only one to fertilize a woman’s egg, but the vast majority never make it that far. They are slowed by mucus, driven off course by the acidity of the vagina and victimized by their own overzealous mobility, which causes them to crash into each other and to exhaust their vital supply of energy too quickly. By the time they reach the egg, most are too weak or misshapen to penetrate it.

How to Preserve Sperm

It is possible to preserve sperm Sperm can be frozen and stored for a period of time. This gives couples the option to have children later in life or to have children if the man becomes infertile.

Sperm Storage

Sperm Storage is the process of preserving sperm so that it can be used at a later time. There are a number of reasons why you might want to store sperm. Perhaps you are a cancer patient who is about to undergo treatment that could affect your fertility. Or maybe you are a man who wants to have children later in life. Whatever the reason, sperm storage can give you the peace of mind of knowing that your fertility is not at risk.

There are two main ways to store sperm: by freezing it or by keeping it alive in a special solution.

Sperm freezing is the most common method of storage. It is safe, effective and can be done at any age. Sperm is frozen in liquid nitrogen and can be stored for many years. When you are ready to use the sperm, it is thawed and injected into the woman’s uterus using in- vitro fertilization (IVF).

The other method of storage is known as “spermatogenesis”. This involves keeping the sperm alive in a special solution and then injecting it into the woman’s uterus when she is ovulating. This method is not as common as freezing because it is more expensive and less effective.

Whatever method you choose, sperm storage can give you the peace of mind that your fertility will not be affected by treatment or age.

Sperm Freezing

The process of sperm freezing, or cryopreservation, involves cooling sperm to sub-zero temperatures in order to preserve them for future use. This can be done either by using liquid nitrogen or by freezing the sperm in a special solution.

Sperm freezing is often used by couples who are facing fertility issues, as it allows them to store sperm for later use. It can also be used by men who are undergoing cancer treatment, as the treatment can sometimes damage or kill sperm cells.

The process of freezing sperm is not without its risks, however. There is a small chance that the sperm cells could be damaged during the freezing and thawing process, which could impact their ability to fertilize an egg. There is also a small chance that the sperm could develop an infection after being frozen.

If you are considering freezing your sperm, it is important to speak with a fertility specialist to discuss the potential risks and benefits.

Sperm Banking

Sperm banking is a process in which sperm is collected and stored for future use. The sperm can be used for fertility treatments such as in vitro fertilization (IVF) or intrauterine insemination (IUI). It may also be used for genetic preservation, in case a man wishes to have children later in life or if he is at risk of losing his fertility due to medical treatment.

There are several ways to collect sperm, but the most common method is through masturbation. Once the sperm is collected, it is then frozen and stored in a sperm bank. The sperm can be thawed and used at a later time.

Sperm banking is not without its risks. There is a small chance that the sperm could be damaged during the freezing and thawing process. There is also a risk of infection if the semen comes into contact with contaminated equipment. However, these risks are generally low and the chances of successfully conceiving with frozen sperm are high.

The Future of Sperm Preservation

In the future, sperm preservation will be an increasingly common term as new technology is developed to allow men to preserve their sperm for later in life. Currently, the most common way to do this is through cryopreservation, which is when sperm is frozen and stored in a tank at a very low temperature.

There are many reasons why someone might want to preserve their sperm. For example, they may want to wait to have children until they are older, or they may be facing fertility problems. Preserving sperm can also be a way to ensure that you have children even if you are not able to have them naturally.

Cryopreservation is not the only method of sperm preservation that is available. There are also new methods being developed that do not require freezing, such as vitrification and desiccation. These methods are still being perfected, but they show promise for being more effective in the future.

If you are interested in preserving your sperm, there are many options available to you. Talk to your doctor about what method would be best for you and your individual needs.


In conclusion, there are many ways to preserve sperm. The most important factor is to use a method that is best suited for your individual needs. There are many factors to consider when choosing a preservation method, including fertility goals, personal preferences, and medical history. Talk to your doctor about which method is right for you.


1. How does one preserve sperm?
Sperm is preserved by storing it at a very low temperature, -196°C to be exact. This can be done using either liquid nitrogen or a purpose-built cryogenic tank.

2. How long can sperm be stored for?
Sperm can be stored for an indefinite amount of time as long as it is kept at -196°C.

3. What is the success rate of using stored sperm?
The success rate of using stored sperm will depend on many factors, including the age of the sperm, the health of the sperm, and how the sperm was stored. In general, however, the success rate is relatively high.

4. What are the risks associated with using stored sperm?
There are some risks associated with using stored sperm, such as an increased chance of twins or triplets, as well as a slightly higher risk of birth defects. However, these risks are generally considered to be minimal.
