Fertility Preservation for Men & Boys

The Center for Human Reproduction’s Dr. Vitaly A Kushnir discusses that freezing sperm is the most common way for men to preserve their fertility.

The most common way for men to preserve their fertility is to just freeze sperm. This has been done for many years and is a well established technique. It’s widely available and it’s relatively inexpensive and can be performed in a very short time, very quickly. So, this option is a great option for men who are facing a new diagnosis of cancer or men who have been diagnosed with some kind of a disease where they may need a radiation or chemotherapy. Also, it’s been used by men who are being deployed in the military, for example. We are seeing many different reasons for men to preserve their fertility. But sperm cryopreservation is the most established technique and is the easiest one. In some cases, men don’t produce sperm for whatever reason, and this also applies to pre-pubertal boys. In these cases, a testicular biopsy can be performed and either sperm can be isolated from the tissue or the whole tissue can be cryopreserved and potentially this allows for viable sperm cells to be preserved from this tissue. In boys, this tissue can later be used in the laboratory either to extract sperm or to reimplant back into the testicle after they’ve undergone treatment for whatever disease they are facing.
