Sperm Freezing

How Is Sperm Freezing Performed?

After the semen sample is evaluated for number and motility, the sample is divided into sample test tubes based on the number of sperms. An equal amount of sperm preservative solution is added to the semen and left in liquid nitrogen vapor. Then, this mixture is placed in liquid nitrogen at -196 degrees Celsius. Samples contained in special tanks are stored in liquid nitrogen. Sperm samples can be stored this way without undergoing degeneration for years.

Sperm cell freezing and storage have been successfully performed for many years.

 * Patients; who will receive to undergo chemotherapy for cancer and who will lose the ability to produce sperms, should be definitely advised to have their sperms frozen. Efficacy of current modes of cancer treatment  have increased post-treatment survival rates. The sperm cells of these patients can be frozen for later use to sustain their fertility.

 *At times, there may not be available sperms in the semen of some patients. As soon as sperm cells are found in the semen of such patients, their available sperm cells are frozen and stored for use in assisted reproduction treatment cycles later.

 *In patients with very low sperm count, further assisted reproduction treatment cycles should be guaranteed via sperm freezing.

 *When no sperm cells are found in the semen but sperm cells are retrieved from the testicle tissue obtained by surgery (TESE), these sperm cells are frozen and stored for later use. Thus, the patient will not need to undergo surgery for each cycle of the assisted reproduction treatment.
