Twin pregnancy using cryopreserved sperm from a man with chondrosarcoma1

Author and Disclosure Information


This case report illustrates the usefulness of sperm banking before radical tumor removal. Sperm was collected from a 25-year-old man with chondrosarcoma and frozen in liquid nitrogen before the patient underwent hemipelvectomy to remove the tumor. The surgery resulted in complete removal of the sarcoma and subsequent impotence and failure of emission. After 10 months of sperm storage, the patient’s wife received the first of three artificial inseminations. On the third attempt, the wife conceived and carried the pregnancy to term, when normal twin infants were delivered.
