CDC reporting unit 91

Conceptions Reproductive Associates of Colorado

271 W. County Line Rd, Littleton, CO 80129 · address reported for 2022.

Own-egg outcomes

Live-birth deliveries per intended retrieval, all diagnoses, for retrievals started in 2021 and linked transfers within 12 months. Age is at retrieval start. Native fractions and protected/missing states are preserved.

Patient agePublished outcomeMatching intended retrievals
<3536.9%439
35-3723.0%317
38-4015.5%251
>405.5%146

Donor treatment outcomes

Live-birth deliveries per transfer in 2022, all recipient ages and all diagnoses. Donated embryos remain a separate population.

Published transfer pathwayPublished outcomeMatching transfers
Fresh Embryos Fresh EggsNo matching cycles0
Fresh Embryos Frozen EggsNo matching cycles0
Frozen Embryos58.7%121
Donated EmbryosHidden by CDCHidden by CDC

Combined donor-egg pathways: ~58.7%. Matching transfers: 121. This site weights the three donor-egg pathways by their matching transfer counts; a ~ marker identifies approximation from rounded published rates. Missing or protected active inputs prevent a combined rate.

Reported activity

Annual ART cycles are attempts, not unique patients. Unlinked and unavailable years remain gaps.

History and coverage, 2013–2022

Ten report years are checked individually. A missing or uncertain identity link stays a gap; it is not a zero or evidence of closure. Same reporting ID does not establish unchanged staff or office coverage. Calendar-year fresh-cycle measures and cumulative retrieval cohorts are different populations.
