How long can cryopreserved material be stored at Reproductive Sciences Center?
Specimens may be stored virtually indefinitely. Prolonged storage requires special arrangement with our center including current contact information. Patients are notified annually regarding number of vials of specimens in storage. What is the genetic effect of cancer treatment on sperm? Few studies have assessed the genetic effect of cancer treatment on sperm. Data so far from small patient populations show no evidence for a higher incidence of congenital malformations (birth defects) in children of former male cancer patients. However, there is evidence that during the period of recovery of sperm production (up to 2 years following treatment), there is a higher percentage of aneuploid sperm (genetically abnormal sperm with missing or extra chromosomes) which might result in higher rates of pregnancy loss, still birth and birth defects. How and why should sperm DNA damage be assessed? The structural organization of sperm DNA is vital for the proper functioning of the sperm. It is not
