HFEA says that most donors “create one or two families, with one or two children each”. The legal maximum is 10 families.
“You’ll normally need to go to a fertility clinic once a week for between three and six months to make your donation.”
Hi Khorton — yes as I responded to Denise, it appears the one year thing must have been specific to the (for-profit) bank I spoke with. They pay so many up-front costs for each new donor I think they want to ensure they get a lot of samples out of each one to be able to cover them.
And perhaps they were highballing the 30+ number, so they couldn’t say they didn’t tell you should the most extreme thing happen, even if it’s improbable.
