New England Cryogenic Center (NECC)

Sperm Bank

Also known as New England Sperm Bank. Started in 1982. There should be a letter in front of the donor number. Also has some Rocky Mt. Cryobank donor numbers. Older NECC numbers (like the single digit ones) seem to have PD-?, which was listed as only D-? on later donor lists. These may also have I-? as an identifier on the profile pages. 2016 NOTE: New England Cryogenic (NECC) refuses to give former donors their own donor numbers. A donor just called them for his donor number and was told "we don't do that". This is deliberately trying to keep donors from (sharing medical information with) offspring and their families.
