To achieve fertilization in In Vitro Fertilization therapy, the number and motility of sperms should be sufficient. However, male reproductive capacity may be low due to ageing and some environmental factors. Sperm freezing procedure can be a good option to take measure for such issues and preserve DNA structure of sperm.

How is sperm freezing performed?
In sperm freezing procedure, sexual abstinence is recommended for 3 days prior to the procedure. Then, sperm samples are collected with surgical techniques. Local or general anesthesia can be induced for this operation.
The collected sperm cells are transferred to Andrology Laboratory and analyzed afterwards; the number, motility and structure of these sperm cells are evaluated. If the collected sperm cells are not suitable for fertilization, recollection can be done. After analysis is completed, the sperms are frozen using a special solution and can be stored at -196 C for up to 5 years.
