Sperm freezing is a simple process that gives the option of achieving pregnancy with your own sperm. It is an easy process that consists of preparing the sperm (a process called capacitation) obtained by ejaculation or by testicular biopsy. The sperm is frozen to preserve it for future use.
When should one preserve his sperm?
- Cancer patients who need to undergo surgery or aggressive gonadotoxic treatment (medication that is toxic for the sperm) that can affect germinal cells.
- Patients that are planning on having a vasectomy.
- Patients who, for reasons unrelated to fertility, cannot be present the day the sperm sample is required.
Sperm Freezing: The Process
Before proceeding to sperm freezing, our doctors will review the patient’s medical history and make sure he has no infectious diseases or reasons that make the procedure unadvisable. Before freezing, the patient will undergo a number of tests.
Once the sample has been collected, the andrology lab team will proceed to analyze the sample obtained.
For the sperm to have the best possible characteristics, we recommend sexual abstinence for 1 to 3 days before freezing. More than 3 days is not recommended.
If the sample presents the quality required, it will be frozen. The sample is prepared with a specific cryoprotector that helps freezing. It will be cooled in liquid nitrogen gradually and then more rapidly until the temperature reaches -196ºC.
Freezing does not affect the quality of the sperm sample, if and only if the seminal quality is within normal parameters. In cases where the quality of the sperm is compromised, freezing could have a negative impact on future treatment results.
Thanks to the continuous investment in the latest technology, every stage of the treatment is performed at the clinic, which reduces the waiting times and increases the chances of pregnancy.
If the patient decides to interrupt the treatment, we commit to reimbursing the portion of the treatment that has yet to be completed.
The monitoring of the treatment is done in an efficient and secure way, maintaining patient privacy.
