Inception and Five-year Run of a Semen Cryobank. Clinical and Behavioral Aspects

Recent developments in infertility treatment, as well as medical and ethical concern to preserve the fertilizing ability of male subjects potentially at risk, led to the inception of a sperm cryobank in our medical center in 1996. Up to the end of the year 2000, 64 young men displaying higher semen values than generally required were accepted as donors, while 305 married (mean age 32.5, range 22-54) and 381 single women (mean age 41.2, range 27-50) were treated by artificial insemination donor (AID), resulting in 251 conceptions. Besides, 437 male subjects aged 15-61 requested sperm cryopreservation. Methodological considerations about sperm cryopreservation, and behavioral implications therefrom, are evaluated.
