What can men do to preserve fertility before cancer treatment?

Men also can take steps to preserve their fertility before undergoing cancer treatment. For example:

• Sperm cryopreservation. This procedure involves freezing and storing sperm at a fertility clinic or sperm bank for use at a later date. Samples are frozen and can be stored for years.
• Radiation shielding. In this procedure, small lead shields are placed over the testicles to reduce the amount of radiation exposure they receive.
