Sperm Freezing
Sperm freezing offers a safe and effective way to preserve fertility for the future. At GAIA Fertily Clinic, an assisted reproduction clinic in Sabadell, we accompany this process providing clear information, respect, and a close, compassionate approach, because we understand that making decisions about fertility is not always easy.
Preserving fertility today does not mean making all decisions right now. It means keeping options open for the future.
What Is Sperm Vitrification?
Sperm vitrification is an advanced cryopreservation technique that allows semen to be stored at extremely low temperatures through ultra-rapid cooling. This process prevents the formation of ice crystals, protecting the cellular structure of sperm.
Thanks to this technique, sperm can remain viable for long periods of time while preserving their fertilising potential.
What Does Semen Vitrification Involve?
The process begins with the collection of a semen sample under controlled and confidential conditions. The sample is then analyzed in the laboratory to assess sperm concentration, motility, and morphology.
Following this analysis, the sperm are prepared and vitrified using specific protocols, then stored in liquid nitrogen tanks at ultra-low temperatures. It is a simple, non-invasive, and safe procedure.
Who Can Benefit from Semen Vitrification?
Cancer Patients
For men who are about to begin oncological treatments such as chemotherapy or radiotherapy, sperm freezing is an essential preventive measure, as these treatments may temporarily or permanently affect sperm production.
Fertility Preservation for Men
Vitrification is also an option for men who wish to postpone fatherhood, are experiencing a progressive decline in semen quality, or simply want to preserve their fertility as a preventive measure.
Assisted Reproduction Treatments
In the context of assisted reproduction, sperm freezing makes it possible to have a backup sample available or to use it when obtaining a semen sample on the day of treatment is not possible.
What Is Sperm Vitrification Used For?
Semen vitrification allows male fertility to be preserved when there is a risk that it may be compromised in the future, whether for medical, personal, or life-related reasons.
It does not imply an immediate decision about fatherhood, but rather the possibility of having viable sperm available when the right time comes.
How Is Sperm Vitrification Performed at Gaia?
At GAIA, the process begins with an initial medical assessment. Our team explains every step clearly and answers all questions before the sample is collected.
The laboratory performs the analysis, preparation, and vitrification following strict safety, traceability, and quality control protocols. In most cases, the entire process can be completed in a single visit.
Frequently Asked Questions About Sperm Freezing
Vitrified sperm can be preserved for many years without time affecting their quality or reproductive potential. As long as proper storage conditions are maintained, the passage of time does not reduce the chances of success.
Vitrification differs from traditional freezing in the speed of the cooling process. Because vitrification uses ultra-rapid cooling, cellular damage is reduced and sperm survival after thawing is improved.
For this reason, vitrification is currently considered the gold standard technique in male fertility preservation.
When performed correctly, vitrification does not negatively affect semen quality. After thawing, sperm can be successfully used in treatments such as artificial insemination or in vitro fertilization (IVF).
Vitrified sperm are used when the patient decides to begin a fertility treatment or when obtaining a semen sample under optimal conditions is no longer possible. Their use is planned on an individualised basis, according to each clinical situation.
In in vitro fertilization (IVF), the eggs are retrieved from the ovaries and fertilized with sperm in the laboratory. Once an embryo is obtained, it is transferred to the uterus to achieve pregnancy.
In ICSI (Intracytoplasmic Sperm Injection), the embryologist injects a single sperm directly into the egg. This technique is usually recommended in cases of male factor infertility, poor semen quality, or previous fertilization failures.
Artificial insemination (AI) is a simpler and less invasive treatment in which sperm are placed directly into the uterus during the ovulatory period. Fertilization then occurs naturally inside the woman’s body.
No. Freezing sperm does not obligate you to use it. It is simply an option that remains available for the future. Many people vitrify their sperm to gain peace of mind and reassurance, without making an immediate decision about fatherhood.
