111 Colchester Ave, Main Campus, Main Pavilion, Level 4, Burlington, VT 05401 · 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.

Donor treatment outcomes

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

Combined donor-egg pathways: Hidden by CDC. Matching transfers: Not published. 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.
