3 collection sites across 2 banks, $1,500/month.
In Colorado: 3 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's six-month quarantine.

Every Colorado site sits on the Front Range — Denver, Boulder, and Loveland. Colorado Springs (~70 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 in all 50 states, including Colorado. The family pays a per-cycle fee ($5k–$100k), usually trait-priced and released from escrow after FDA clearance — not a monthly wage, so 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.
