Infertility and IVF statistics: what the numbers say about success rates and who can afford treatment

She brought a spreadsheet to her first visit with me. Eighteen months of basal body temperatures, ovulation strips photographed and dated, two early losses logged in a column labeled "weeks." She was 36 and had already decided something was wrong. What she wanted was a number. "If we do IVF," she asked, "what are my odds?"

The honest answer is that it depends on which number you mean. Odds per embryo transfer, per egg retrieval, and per patient who keeps going until the money runs out are different statistics, and they are not close to each other. Clinics do not always make clear which one a quoted percentage refers to. That ambiguity is where a lot of false hope lives.

What follows is what federal surveillance data, the WHO, and the health policy researchers at KFF actually report: how common infertility is, who carries the diagnosis, what treatment achieves at each age, and who ends up able to pay for it.

How common is infertility

The CDC's Division of Reproductive Health puts it plainly: 1 in 5 married women aged 15 to 49 with no prior births are unable to get pregnant after a year of trying. Widen the definition slightly to include women who conceive but cannot carry a pregnancy to term, and the figure rises to about 1 in 4, or 26%, in that same group.

Those numbers describe a specific population, and the specificity matters when you see them quoted loosely online: married women who have never given birth. Look at all US women of reproductive age and CDC/NCHS FastStats reports impaired fecundity at 13.4%, from the 2015-2019 National Survey of Family Growth. Both are correct. They answer different questions.

Globally, the World Health Organization's November 2025 fact sheet estimates that approximately one in every six people of reproductive age worldwide experience infertility in their lifetime. That is a lifetime figure rather than a point-in-time prevalence, which is why it sits higher than most national snapshots.

None of these are rare-disease numbers. A condition affecting one in six people over a lifetime is closer in scale to hypertension. Yet infertility care is still financed and discussed as though it were a boutique service.

Whose diagnosis is it

The most useful thing you can say early in a fertility workup is that this is a two-person evaluation. Patients arrive assuming the problem is theirs. Frequently it is not.

The NICHD's position is that one-third of infertility cases are caused by male reproductive issues, one-third by female reproductive issues, and one-third by both partners together or by factors that remain unknown. A semen analysis is cheap, non-invasive, and fast, and it is still ordered later than it should be.

The clinic data reflects the same pattern, imperfectly. In CDC's 2021 national summary report, male factor was listed as a reason for using ART in 28% of cycles, alongside diminished ovarian reserve at 27%, unexplained factor at 11%, tubal factor at 10%, and endometriosis at 6%. CDC's own data validation found male factor is underreported in that surveillance system, so 28% is a floor rather than a ceiling.

The 27% figure for diminished ovarian reserve maps directly onto the age curve; our piece on fertility and age covers how egg quantity and quality change over time. Conditions that disrupt ovulation or damage pelvic anatomy are a separate lane, and both PCOS and endometriosis show up repeatedly in fertility clinic populations.

How much IVF happens in the US

IVF is no longer a rare intervention, and the CDC surveillance numbers make that obvious. In 2022, there were 435,426 ART cycles performed on 251,542 unique patients at 457 reporting US clinics, resulting in 94,039 live-birth deliveries and 98,289 live-born infants.

Those infants represented about 2.6% of all babies born in the United States that year. Roughly one in every 38, which in a large hospital nursery is more than one newborn a day.

The ratio of cycles to patients is the quieter statistic there. Roughly 435,000 cycles across roughly 252,000 patients is about 1.7 cycles per patient in a single calendar year, which tells you repeat treatment is normal rather than exceptional. Patients who budget for one cycle are budgeting against the data. If you are already in treatment, our IVF due date calculator handles the day-3 versus day-5 transfer arithmetic that trips people up.

IVF success rates by age

Here is where the "which number are you quoting" problem becomes concrete. CDC's 2021 national summary reports live-birth deliveries per intended egg retrieval, using a patient's own eggs, at 50.7% under 35, 36.3% at 35 to 37, 23.3% at 38 to 40, and 7.9% over 40.

The drop from 23.3% to 7.9% between the late thirties and the early forties is the steepest step in the table, and the one patients are least prepared for. Nothing in a woman's experience of her own body signals it.

Now the more optimistic framing from the same report. Among new patients, the share having a live-birth delivery after all intended retrievals (the cumulative result of persisting through more than one attempt) was 61.5% under 35, 49.5% at 35 to 37, 35.2% at 38 to 40, and 13.2% over 40. Persistence buys real ground at every age.

What persistence costs is in the next line of the same table. The average number of intended retrievals per live-birth delivery was 2.0 under 35, 2.8 at 35 to 37, 4.3 at 38 to 40, and 12.7 over 40. That last figure deserves a caveat I give patients directly: an average of 12.7 retrievals per live birth is a course of treatment very few households can finance at the price points below, so the 13.2% cumulative rate over 40 describes what is clinically possible rather than what most patients will actually be able to complete.

One caveat on all of this: these are cycles using a patient's own eggs. Outcomes with donor eggs follow the donor's age, not the recipient's, and behave very differently.

What a cycle costs

The White House's October 16, 2025 fact sheet on IVF access states that cost can range from $12,000 to $25,000 per cycle and that multiple cycles may be needed. The same document notes fertility drugs represent almost 20% of a treatment cycle's total cost.

Set that against the retrieval arithmetic from CDC. A patient under 35 averaging 2.0 retrievals is looking at roughly $24,000 to $50,000 for a live birth if she pays out of pocket. A patient at 38 to 40 averaging 4.3 retrievals is looking at roughly $52,000 to $108,000 on the same arithmetic. This is the part of the conversation I find hardest, because the medicine is often willing and the financing is not.

The 20% figure for drugs is doing quiet policy work in that fact sheet. It underpins federal actions on medication pricing. TrumpRx.gov lists discounts negotiated with EMD Serono for Gonal-F, Ovidrel, and Cetrotide, and CMS estimates savings of up to $2,200 per cycle of fertility drugs. KFF's analysis noted the limit: if drugs are a fifth of a cycle's cost, discounting them leaves the other four-fifths untouched. KFF also found excepted-benefit HRA contributions capped at $2,150, roughly one-tenth of a single IVF cycle.

The coverage gap

KFF's State Health Facts tracker counted 23 states requiring private insurance coverage of infertility services as of November 2025. The other 27 do not. Where you live determines much of what you will pay, which is not how anyone would design a system on purpose.

The mandates also have a hole most patients discover only after calling their benefits line. KFF's October 2025 analysis notes that state laws do not apply to self-funded plans, which cover about two-thirds (67%) of workers with employer-based insurance. Those plans answer to federal ERISA rules, not state insurance law. A patient can live in a mandate state, work for a large employer there, and still have no IVF benefit.

Voluntary employer benefits fill part of the gap, unevenly. The KFF Employer Health Benefits Survey found 27% of employers with 200 or more workers offer IVF coverage, rising to 53% among those with at least 5,000 workers. Coverage tracks employer size, which tracks industry and wage level.

The state picture is moving. California's SB 729 large-group IVF mandate applies to plans new or renewing on or after January 1, 2026. KFF's summary is explicit that it excludes self-insured and religious employers. Georgia's mandate covering iatrogenic infertility also begins in January 2026. The District of Columbia's took effect January 1, 2025. Each expands the pool of covered patients while leaving the self-funded exemption intact.

Who actually uses fertility services

You can watch the coverage gap turn into a usage gap in the NCHS data. Data Brief No. 542, published December 17, 2025 and covering 2022-2023, reports that among women ages 20 to 49 the share who had ever used any fertility services rose with family income: 9.5% below 150% of the federal poverty level, up to 17.2% at 450% or more of the FPL.

Insurance type shows the same pattern. In that survey, 16.0% of women with private health insurance had ever used fertility services, against 9.4% with public insurance and 9.6% of uninsured women.

What bothers me clinically is that infertility prevalence does not follow income. There is no mechanism by which women under 150% of the poverty line have healthier tubes or better sperm parameters than women at four times that income. What differs is who walks through the clinic door. The 17.2% figure measures access, not need, and our look at women's healthcare access disparities finds the same shape across specialties.

The twin rate collapse

There is one genuinely good news story in this data, and it rarely gets told because the metric that improved is not the one patients ask about. For years, IVF's signature complication was multiple pregnancy. Transferring several embryos raised the odds that one would implant, at the cost of twin and triplet pregnancies with higher rates of preterm birth and NICU admission, plus preeclampsia. The field's answer was elective single embryo transfer, and CDC's 2021 report shows how completely it worked.

Over that decade, the share of ART-conceived infants born as singletons rose from 57.8% in 2012 to 89.3% in 2021. Twins fell from 40.2% to 10.4%, triplets or more from 2.0% to 0.3%. A treatment that used to produce twins in four of every ten infants now produces them in one.

That is a maternal safety improvement of a size obstetrics almost never achieves, from changing one clinical decision. The trade-off is real: single embryo transfer usually means more transfers per patient, and more time and cost.

The policy fight, and the data itself

Two years after the Alabama Supreme Court's 2024 ruling on frozen embryos, the legal status of IVF is still genuinely unsettled. KFF has noted that the Project 2025 blueprint refers to embryos as "aborted children" and that influential conservative organizations including the Southern Baptist Convention and the Catholic Church expressly oppose IVF. In 2026 sessions, embryo-related restrictions were defeated in several states, while Virginia moved to add up to three IVF cycles to its essential health benefits benchmark plan for 2028.

In Congress, the Right to IVF Act was reintroduced on July 23, 2026 as S. 5108, sponsored by Senator Tammy Duckworth and timed to World IVF Day. It would establish a statutory right to assisted reproduction and require coverage of that care in employer plans, the Federal Employees Health Benefits program, TRICARE, the VA, Medicaid, and Medicare. Its 2024 predecessor, S. 4445, failed on near-unanimous Republican opposition, and Representative Lauren Underwood's Health Coverage for IVF Act of 2025 has not moved.

The part of this that unsettles me most is the least visible. According to Congressional Research Service In Focus report IF13144, the CDC researchers who conduct ART surveillance and manage the National ART Surveillance System were terminated in April 2025. Congress has responded from both chambers: Senate Report 119-55, accompanying S. 2587, directs CDC to restore its ART surveillance work back to full capacity, while House Report 119-271, accompanying H.R. 5304, directs CDC to publish data on egg-donor complications and on eggs fertilized and embryos created per cycle.

What hangs on this is the clinic-by-clinic reporting mandated by the 1992 Fertility Clinic Success Rate and Certification Act, a law that exists because clinics were advertising success rates with no standard definition and no audit. CDC's newest published national figures are still from 2022, and the summary tables cited here are from 2021.

Every percentage here traces back to that surveillance system. If it degrades, patients lose the only independent yardstick for judging a $12,000 to $25,000 decision, and clinics keep their marketing departments either way.

The practical advice has not changed much. Get both partners evaluated early rather than sequentially. Ask any clinic which denominator its quoted success rate uses, and ask your benefits administrator whether your plan is self-funded before assuming a state mandate protects you. If you are still trying to conceive, using an ovulation calculator and knowing the clinical signs of ovulation is worth doing well before a year passes, since a year is the threshold at which a workup is indicated.

Frequently asked questions about infertility and IVF

How common is infertility in the United States?

The CDC reports that 1 in 5 (19%) married women aged 15 to 49 with no prior births cannot get pregnant after a year of trying, and about 1 in 4 (26%) have difficulty getting pregnant or carrying a pregnancy to term. Across all US women aged 15 to 49, CDC/NCHS FastStats puts impaired fecundity at 13.4%.

Is infertility usually the woman's problem?

No. The NICHD reports that one-third of infertility cases are caused by male reproductive issues, one-third by female reproductive issues, and one-third by both partners or unknown factors. Male factor was listed as a reason for using ART in 28% of US cycles in CDC's 2021 report, and CDC's own data validation found that figure underreported.

What are IVF success rates by age?

Using a patient's own eggs, CDC's 2021 national summary reports live birth per intended egg retrieval at 50.7% under age 35, 36.3% at 35 to 37, 23.3% at 38 to 40, and 7.9% over 40. Cumulatively, after all intended retrievals, new patients reached a live birth 61.5% of the time under 35 and 13.2% over 40.

How much does IVF cost?

The White House's October 2025 fertility fact sheet puts a cycle at $12,000 to $25,000, with drugs almost 20% of that total, and notes multiple cycles may be needed. CDC data shows an average of 2.0 intended retrievals per live birth under age 35, rising to 12.7 over 40, so total cost scales sharply with age.

Does insurance cover IVF?

Sometimes. KFF counted 23 states requiring private coverage of infertility services as of November 2025. Those mandates do not apply to self-funded employer plans, which cover about 67% of workers with employer-based insurance. Separately, 27% of employers with 200 or more workers offer IVF coverage, rising to 53% at employers with 5,000 or more.

How many babies are born through IVF?

In 2022, US clinics performed 435,426 ART cycles on 251,542 unique patients at 457 reporting clinics, according to CDC surveillance. Those cycles produced 94,039 live-birth deliveries and 98,289 live-born infants, about 2.6% of all US births that year.

Does IVF still cause a lot of twin pregnancies?

Far less than it used to. CDC's 2021 report shows the share of ART-conceived infants born as twins fell from 40.2% in 2012 to 10.4% in 2021, while singletons rose from 57.8% to 89.3%. Single embryo transfer is the reason.
