Sperm Freezing
How are sperm cells frozen?
After evaluating the semen sample for count and motility, the sample is divided into tubes based on sperm count. A protective solution is added to the semen, and after initially being exposed to the vapor of liquid nitrogen, it is immersed in liquid nitrogen at -196 degrees Celsius. The samples are stored in special tanks in liquid nitrogen and can be preserved for many years without deterioration.
Sperm cells have been successfully frozen and stored for many years.
Sperm freezing is strongly recommended for patients diagnosed with cancer who will undergo chemotherapy and may lose sperm production. With the effectiveness of modern cancer treatments, post-treatment survival rates have increased. Freezing sperm cells protects their fertility for later use.
In some patients, sperm cells may not always be present in the semen. In these cases, when sperm cells are observed, they are frozen and stored for later use in IVF treatments.
In cases of very low sperm count, sperm freezing is applied to ensure treatment success.
In cases where there are no sperm cells in the semen but sperm cells are found in the tissue taken from the testicles through surgery (TESE), these are also frozen and stored for later treatments. This way, the patient does not need surgery for each IVF attempt.
