Sperm freezing or semen vitrification is an advanced cryopreservation technique that allows sperm to be frozen at extremely low temperatures (-196ºC) to keep them viable and functional for a prolonged period. Unlike traditional freezing, vitrification prevents the formation of ice crystals and the use of high concentrations of cryoprotectants, which can damage cells.
This technique is particularly useful for men who want to preserve their fertility before undergoing medical treatments that could affect their ability to conceive in the future, such as chemotherapy or radiotherapy.
Sperm and egg freezing allows gametes to be stored at very low temperatures for future use. This procedure is vital for many individuals and couples facing difficulties conceiving naturally.
This type of freezing is already common in egg and embryo preservation, with excellent results. In our laboratory, we are pioneers in applying this technique to sperm samples and have pregnancy rates that support its use.
At IVF-Life, providing patients with the latest advances in fertility is essential. Therefore, sperm vitrification is an innovative technique supported by the most advanced technology, increasing pregnancy rates.
Since sperm are small cells with little internal volume, semen freezing is done slowly, preventing crystal formation that could damage their internal structure.
After the initial consultation, the semen sample is collected. If the patient cannot produce sperm naturally, an alternative technique such as sperm extraction via aspiration or testicular biopsy may be used.
Once the semen sample is obtained, it is analyzed in the laboratory to evaluate the quantity and quality of the sperm. Cryoprotectants are added to the semen to protect the sperm during the freezing process.
The sample is gradually cooled until it reaches a temperature of -196ºC.
Frozen sperm is stored in sperm banks that are carefully monitored, where they can remain viable for many years to be used when the patient needs them.

Additionally, sperm freezing is commonly used in assisted reproduction procedures such as in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI). In these treatments, frozen sperm can be thawed and used to fertilize eggs in case a fresh attempt is unsuccessful. Using frozen sperm has proven to be as effective as using fresh sperm, making it a routine procedure. Similarly, vitrification is also used for sperm donors, who donate altruistically to help couples and single mothers achieve pregnancy.
