Analysis of the feasibility of storing human semen for future artificial insemination.

Patients about to undergo vasectomy, retroperitoneal lymph node dissection, pelvic radiotherapy or chemotherapy frequently wish to store semen for future artificial insemination. The probability that this will result in a pregnancy is approximately 33% and the logistics are complicated. These problems are discussed and a cost analysis is presented. A list of semen banks presently storing homologous human semen and registered with the American Association of Tissue Banks also is presented.
