Reasons for Storage


There are numerous reasons to store sperm for possible future use.

Below is a list of some of the most common reasons for sperm storage.

Cancer Diagnosis

People who have been diagnosed with cancer and are facing the possibility of chemotherapy, radiation, or surgical procedures that could impact their future fertility often choose to store their sperm. CryoGam understands the urgency of your situation and can schedule your sperm banking appointments before your treatment begins.



People who are considering elective sterilization should bank sperm PRIOR to their vasectomy. Please call ahead and schedule your sperm banking appointments, allowing for plenty of time to store more than one specimen (if needed) before the procedure.


Vasectomy Reversal (Vasovasostomy)

A vasectomy can be surgically "reversed" and will have varied fertility outcomes based on factors including length of time since vasectomy, the development of blockages due to scarring and autoantibodies. It is recommended that patients cryopreserve sperm shortly after a successful vasovasostomy in case scar tissue develops and subsequently blocks the vas deferens. CryoGam also offers sperm cryopreservation during the vasovasostomy. Please contact our office for a list of urologists that we work with in Northern Colorado and the Denver Metro Area.


Prior to ART Procedure

Some couples bank sperm specifically for infertility treatments, for example, timed inseminations, IVF, or simply due to scheduling conflicts. CryoGam is equipped to work with you and your physicians regarding your treatment.


Testosterone Therapy

Testosterone (in the form of gels, injections, etc...) may be given to treat conditions such as hypogonadotropic hypogonadism which is a syndrome that  results in low testosterone. Testosterone treatment is known to decrease hormones of the brain that signal the testes to produce sperm; thus compromising fertility. It's recommended that you store sperm prior to starting testosterone replacement therapy.


Estrogens, Progestin, and/or Anti-Androgens (including Lupron, Aldactone, Proscar, Propecia, etc...)

These can decrease sperm production resulting in decreased fertility and in some cases, sterility. Sperm storage is advised prior to the start of any hormone replacement therapy. In some instances, additional screening and testing may be required. Please contact our office with the specifics regarding your situation so that we can help you make informed decisions about your sperm storage.


Gender Affirming Surgery

Many transgender patients choose to preserve their fertility by storing sperm prior to cross-hormone therapy and/or surgery. CryoGam has extensive knowledge and expertise in this area and can explain the options in regards to screening, testing, and sperm storage for use with a current or future partner. Please contact us with the specifics regarding your situation so that we can assist you in choosing a storage plan that is right for you. Keep in mind that additional screening, testing and time requirements may apply. Please see our directed donor page or contact us to obtain more information.


Please keep in mind that we recommend abstaining for at least 3 days prior to each ejaculate, regardless of the reason.
