Male Fertility Preservation

Sperm freezing is a process of extracting, freezing and storing of the man’s spermatozoa. The freezing and storing of sperm is done through a process of cryopreservation. There could be several reasons due to which men may choose to have their fertility preserved. We will get into this in more detail further on. An important point to note is that sperm that have been cryopreserved can be a viable option for insemination indefinitely.

What is Male Fertility Preservation or Sperm Freezing?

Sperm Freezing is also referred to as Sperm Banking or Cryopreservation. It involves collecting, analyzing, freezing and storing of sperm for later use. Frozen sperm are stored in a sperm bank, hence the term sperm banking. The process of freezing sperm was first introduced in the 1950’s and there have been several additional advancements made to the process in the years that followed.

Advantages of Sperm Freezing or Male Fertility Preservation

There could be several factors like lifestyle, hereditary issues and health conditions that could lead to a deterioration of the quality of the sperm. Having your sperm frozen provides men with a safeguard to having children if they would like to do so in the future. Even as you grow older the quality of sperm tends to deteriorate. Sperm freezing at a younger age provides you with an opportunity to use the frozen sperm to procreate at a later date when you are ready to have a child.

Who is Sperm Freezing Suitable For?

Male Fertility Preservation or Sperm Freezing Process


Screening process

Even before the sperm can be collected, the man has to go through a blood test to screen for infections such as HIV, Hepatitis B and Hepatitis C. Once the donor’s blood work is clear he can move onto the next step in the sperm freezing process.


Sperm collection

A man can provide his sample at the sperm bank/clinic or at home. Sperm is collected through the process of masturbation. The donor is provided with a sterile container for a collection of the sperm. It is important that the donor does not have an ejaculation for 2 – 5 days before the procedure. If the last ejaculation took place less than 2 days ago it could lead to the sample count being too small. A typical ejaculate contains between 40 million to 600 million sperm. If the last ejaculate was too long ago it could lead to the sperm being too immotile.


Sperm Analysis

Once the sample is provided the lab technicians analyse the samples for volume, viscosity and pH levels. The sperm are also microscopically evaluated to determine motility, sperm count, morphology and other important factors.


Sperm freezing

To prevent damage to the sperm from freezing a non-reactive cryoprotectant is added to the sperm sample. After being significantly cooled the sperm is added to liquid nitrogen at minus 196 degrees Celsius.


Thawing the sperm for use

When the sperm is required to be used the thawing process is undergone. This step in the procedure is equally as vital as the freezing process and the same precautions need to be taken before the frozen sperm can be used. During thawing, it is important that the sperm cells regain their normal biological activities without being subjected to abrupt temperature variations. The protocol suggests using temperatures of 37 degrees Celsius for thawing. Once thawed the sperm is separated from the cryoprotectant by washing it in a culture medium and centrifuging it.

Sperm Freezing success rates

Preserving the male fertility using the method of sperm freezing is extremely successful. Since 1950 the success rates of cryopreservation have gone up drastically. The rate of success for conception using frozen sperm is entirely dependent on the quality of the sperm that was first deposited. During an IVF or IUI procedure, good quality frozen sperm will give a better outcome compared to the sperm of poor quality.
