The question "how much does sperm donation pay" is a common one we get here at SpermCenter.
The easiest answer is that it depends on the bank. Some banks, like California Cryobank, pay $100 per donation, while others like Fairfax Cryobank may pay more or less depending on whether there is a bonus involved, whether they pay up front, etc.
Bonuses may be offered for things like baby or adult photos, and you may get more if you decide to become an open donor (which usually means you allow your offspring to contact you and get access to medical information when they turn 18).
Your best option is to contact the bank or fertility clinic in your area, as they can give you specific quotes.
