It is now routine to offer men the opportunity to bank sperm prior to medical treatments where there is a high risk of testicular damage. Some men also elect to bank sperm prior to vasectomy or before embarking on a high-risk activity, such as joining the armed services. This book examines the processes involved in banking sperm from sample production and storage, the subsequent treatment of the patient and the maintenance of the samples in storage, to the process of follow-up and the ultimate fate of frozen samples. Sperm Banking: Theory and Practice will be of particular interest to andrologists and embryologists involved in the running and establishment of sperm-banking services. The book will also be useful to medical and nursing professionals and counsellors involved in the diagnosis and treatment of conditions where there is a risk of infertility as a consequence of the treatment, including oncologists, hematologists and urologists.
