In CDC's 2021 state data brief (published December 2023), 1 fertility clinic in Montana reported ART data. Women living in Montana underwent 412 ART procedures, or 1,761 per million women aged 15 to 49 (U.S.: 3,250), and 1.5% of babies born to Montana residents in 2021 were conceived with ART (U.S.: 2.3%). CDC counts by the patient's state of residence.
| 2021, by state of residence | Montana | United States |
|---|---|---|
| Clinics that reported ART data to CDC | 1 | 453 of 501 |
| ART procedures for residents | 412 | 246,087 |
| ART procedures per 1 million women aged 15 to 49 | 1,761 | 3,250 |
| Embryo-transfer procedures | 360 | not listed |
| Live-birth deliveries from those procedures | 176 | 91,906 |
| Live-born infants from those procedures | 179 | 97,128 |
| Share of all infants born in 2021 conceived with ART | 1.5% | 2.3% |
Source: CDC, State-Specific ART Surveillance, 2021 Data Brief (published December 2023). Procedures exclude cycles in which eggs or embryos were only banked.
The 412 procedures for Montana residents included 360 embryo transfers and resulted in 176 live-birth deliveries and 179 live-born infants. Counting births in the calendar year instead, 166 of the 11,231 babies born to Montana mothers in 2021 were conceived with ART.
Because CDC counts by state of residence, Montana women treated at clinics in other states are included in Montana's numbers. CDC notes that state figures may not reflect the clinics located in that state for this reason. With one reporting clinic in the state, that distinction matters here.
Benefits and clinic options change. Confirm with your insurer and the clinic before you start.
Map to the Positive gives a cutoff by age for when to be evaluated, because the right moment is not the same for every woman:
| Age | How long before evaluating | Why |
|---|---|---|
| Under 30 | 12 months | Full ovarian reserve |
| 30 to 34 | 12 months | Reserve beginning to decline |
| 35 to 37 | 6 months | Accelerating egg loss |
| 38 to 40 | 6 months | Reduced egg quality |
| 41 to 42 | 3 months | Time is a critical factor |
| Over 43 | Immediate evaluation | Limited biological window |
From Map to the Positive, Chapter 29.
For women between 35 and 40, the book notes that every additional 6 months of waiting can mean a measurable drop in the success rate of future treatment.
The age cutoffs, the red flags that justify going sooner and the types of specialist are in Chapter 29 of Map to the Positive, in Station IV. The station goes on to choosing a doctor, the treatment ladder and IVF step by step.
