More than thirty years ago it was shown that the human male gametes, or spermatozoa, were capable of undergoing freezing in liquid nitrogen, storage at minus 196 degrees Celsius for indefinite periods, thawing, and induction of pregnancy leading to a normal birth. Thus, a technique of sperm storage was introduced that allows a man to preserve his potential for indefinite periods of time, whether weeks, months, or years. This process of sperm banking is known as cryopreservation.
Especially in the last decade, research in the field of freezing technology has resulted in marked advances in sperm cryopreservation. As a direct result of the increased safety, success, and availability of the technique, there recently has been a dramatic increase in interest by men to store their sperm in an established sperm bank. Many questions are usually associated with such a step, in part because freezing of sperm is a procedure that still is relatively new and associated with the latest in contemporary biological technology. Furthermore, it is a step that also requires considerable self-understanding on the part of the man in order for the director and staff of the sperm bank to plan with foresight a storage program that will adequately meet his future reproductive needs.
In an attempt to facilitate an understanding of the technology, we have compiled a number of the most frequently asked questions (FAQ's) by men considering the advantages of sperm banking. They include general inquiries about the cryopreservation program offered by CryoGam Colorado, LLC.
