Sperm Freezing

Sperm freezing or sperm cryopreservation is a preservation technique that has been used for more than 75 years for use in assisted reproductive treatment, such as artificial insemination or in vitro fertilization.

The process is relatively simple: the semen sample that the patient takes in the laboratory through masturbation is collected and a treatment is given to preserve the sperm prepared to be fertilized.


How is it done?

  • Collection of the semen sample. After collecting the semen sample, the sperm are analyzed and the best ones are chosen, discarding those that have died, have little mobility or some defect.
  • Dehydration. The sample must be dehydrated to remove all traces of water that may form crystals.
  • Vitrification. Once the sample has been dehydrated, it is placed in liquid nitrogen at -196 ° C, which freezes the sperm in seconds and allows them to retain their qualities.
  • Storage. Frozen sperm are stored indefinitely until required for use in an assisted reproductive technique.

When to consider doing it?

Sperm freezing or sperm cryopreservation is recommended in the following cases:

  • Cancer patients before chemotherapies or radiotherapies that can damage the quality and quantity of sperm; for example, in the case of testicular lymphoma, which can cause infertility.
  • Before testicular surgery, prostate surgery or hormone replacement therapy in transgender people.
  • Before a vasectomy in case of wanting to postpone paternity.
  • Before undergoing fertility treatments to have healthy and ready sperm available when needed.
  • Men with low sperm count or sexual disorders such as erectile dysfunction or premature ejaculation.

In addition to these cases, athletes or people with high-risk work, for example those who are exposed to pesticides, environmental toxins, lead or radiation, which in addition to having a risk of affecting their fertility, can damage the quality of sperm.

How to prepare for the procedure

Before submitting the patient to the procedure, the specialist requests blood tests to rule out the presence of diseases such as HIV, hepatitis, herpes, among others; In addition, a semen sample is often required to analyze sperm motility, sperm count, and other factors.

Before the procedure, the patient must have 3 to 4 days of sexual abstinence to have a good amount of semen and good quality sperm; Longer abstinence is not recommended as it may increase the number of immobile sperm.


Success rate

A frozen sperm sample suffers some mobility impairment, however this is not significant (especially in cases of in vitro fertilization) and the loss is based on individual differences. However, current techniques seek to obtain samples with better quality even in prolonged storage times.

Therefore, after the freezing and thawing of a semen sample, a count of more than 10 million motile sperm can be obtained, ready to be used in reproduction treatments.


Sperm Freezing Cost

In the United States, the price of freezing sperm can exceed a thousand dollars between consultations, clinical tests and the cryopreservation process; However, the alternative of going to Tijuana, Mexico, a city known as the capital of medical tourism, is increasingly profitable as it finds treatments up to 3 times cheaper than in the US, but with equally trained specialists and in clinics with cutting edge technology.

The Fertility Center is the alternative you are looking for high quality assisted reproduction treatments, with successful results in our patients and at a more affordable price than in the USA. Schedule an assessment appointment and check it out yourself.

Frequent questions


Is it a safe procedure?

Sperm freezing is generally considered a safe and routine procedure when performed by qualified healthcare professionals in reputable facilities, and based on research, there are currently no harmful risks to children born with frozen sperm. Therefore, this process has been used for decades and is widely used for a variety of reasons, including fertility preservation, sperm donation and assisted reproductive technology (ART).

Before undergoing sperm freezing, individuals are required to first discuss the procedure, potential and success rate with their healthcare provider.

But overall, when performed by experienced professionals in well-equipped facilities, sperm freezing is considered safe and has helped many individuals and couples to preserve fertility and achieve their reproductive goals.


Is it possible to freeze my sperm at home?

It is not possible to freeze sperm successfully at home. Sperm freezing needs to be done in a specialized laboratory with proper quality control. The average temperature of a home freezer is around minus 18 degrees Celsius. While sperm needs to be stored at minus 196 degrees Celsius.


How long can it stay frozen?

Indefinitely, there is no time limit; Pregnancies have even been obtained with samples that had been frozen for up to 15 years.


Who is a good candidate?

For men who want to store their sperm for future use, for example because they still want to delay having children. Those who are undergoing certain medical treatments, those who are facing a health diagnosis such as cancer, those who have a high-risk job that could unexpectedly compromise their fertility, and those who are young or healthy are also good candidates for sperm freezing to ensure the availability of quality sperm in the future.


When is the best age to do it and is there an age limit?

When is the best age to do it and is there an age limit? In men, age is not a limiting factor, since what is sought in sperm is quantity, good quality and an adequate mobility.


Does it require anesthesia?

Sperm freezing does not require anesthesia as the procedure involves taking a semen sample through masturbation. The process is relatively simple and non-invasive.

The individual providing the sperm sample is usually asked to masturbate into a sterile container. The collected semen is then processed to separate the sperm from other components, and the sperm is then frozen and stored for later use. This process is usually well tolerated without the need for anesthesia.


What happens if I don’t use all my sperm during the treatment?

There is no risk whatsoever. If you have frozen sperm that you don’t want to use, you have a few alternatives:

  1. Donating it to someone else. You may be eligible to donate your sperm to someone else who desperately wants a baby.
  2. Donating it for training. You can allow your sperm to be used and stored for possible use by designated health personnel to practice the techniques involved in fertility treatments.
  3. Donating for research. Research on eggs, sperm and embryos is invaluable in helping scientists understand the causes of infertility and develop new treatments.
  4. Disposal. Some people prefer to dispose of their sperm. Sperm that are no longer needed are removed from the freezer and allowed to die naturally at warmer temperatures.
