4 open collection sites across 2 banks, $1,500.
In Colorado: 4 open walk-in bank sites. Known-donor agencies work nationwide — including Colorado — so a directed match is an option even where no bank is within driving distance.
Colorado's sites cluster on the Front Range: Seattle Sperm Bank in Denver — no height requirement and $100 same-day cash per visit — alongside Cryogam, a local bank in Loveland, Denver, and Boulder that doesn't publish its pay.
Seattle Sperm Bank in Denver advertises up to $1,500 a month and, unusually, pays $100 in same-day walk-out cash per visit rather than deferring everything — plus it has no height requirement. Cryogam, the local Front Range bank, doesn't publish what it pays, so we flag it as hidden rather than guess. As always, banks hold part of each payment until samples clear the FDA quarantine.

Every Colorado site sits on the Front Range — Denver, Boulder, and Loveland. Colorado Springs (62 mi) is drivable; Grand Junction and the Western Slope have no nearby site.
A separate route from the walk-in banks above: directed / known-donor agencies match you to specific intended parents and work nationwide, including Colorado. Each agency's per-cycle figure is on its profile. It doesn't sort against bank pay.
“MSM” = whether the agency welcomes gay/bisexual donors. Directed donation is exempt from the FDA anonymous-bank deferral, but only Seed Scout says so on its own pages — treat “Ask agency” as unconfirmed, not a no.
Bank or agency — how to choose
Legal note
Colorado, under its Uniform Parentage Act (C.R.S. §19-4-106), provides that a sperm donor is not the natural parent of a child conceived through assisted reproduction.
Sperm donor pay in Colorado runs $1,500 across 2 banks. Seattle Sperm Bank pays the most, up to $1,500/month. These are advertised ceilings — most donors take home less, and several banks defer part of each payment until samples clear the FDA quarantine.
There are 4 open collection sites in Colorado: Denver (Seattle Sperm Bank), Loveland (CryoGam Colorado), Denver (CryoGam Colorado), Boulder (CryoGam Colorado). You have to visit a site in person, so proximity is the real constraint.
Seattle Sperm Bank, with a site in Denver, at up to $1,500/month. Higher pay usually comes with stricter screening or a longer commitment.
CryoGam Colorado has the lowest published barriers. Acceptance rates are bank-claimed, though, so treat them as marketing rather than your real odds.
Requirements vary by bank. Age, height, and education on this page come from each bank's directory record. The main bottleneck is biological: whether your sample survives the freeze/thaw process.
Yes. Walk-in banks require in-person visits, so they only help if a site is within driving distance. Known-donor agencies work nationwide — including Colorado — and each agency's per-cycle figure is on its own profile. It's also the practical route for gay and bisexual donors.
