Subspecialty fellowship of OB/GYN.

Also called: MFM, perinatology; practitioners are perinatologists. Not a base residency; you reach it through an OB/GYN residency, then a fellowship. Organ system: the pregnant patient and the fetus, the physiology of two lives at once.

The 30-second version

Maternal-Fetal Medicine is the high-risk-pregnancy subspecialty of OB/GYN, the physician you call when a pregnancy stops being routine. MFMs manage medically complex pregnancies (preeclampsia, diabetes, placental disorders, prematurity, maternal heart or kidney disease, multiples), read the detailed obstetric ultrasound, do prenatal diagnosis and genetics counseling, perform procedures like amniocentesis and CVS, and, at the far end of the field, participate in fetal intervention and surgery. It's the cerebral, physiology-heavy, imaging-rich corner of obstetrics, and among the better-paid OB subspecialties. It also concentrates some of the hardest conversations in all of medicine. That mix of the "internal medicine of obstetrics" plus relentless emotional weight is the whole personality of the field.

What they actually do

Maternal-fetal medicine subspecialists take care of pregnancies where something has gone, or might go, seriously wrong for the mother, the fetus, or both. A typical practice mixes several distinct service lines: high-risk obstetric management (co-managing or primarily managing complicated pregnancies: diabetes, hypertension and preeclampsia, twins and higher-order multiples, placental disorders, maternal cardiac or renal disease); obstetric ultrasound and prenatal diagnosis (directing and reading a high-volume ultrasound unit for detailed anatomy scans, Dopplers, and growth surveillance); genetics counseling (aneuploidy screening, carrier status, and walking families through anomalies); and procedures (amniocentesis, chorionic villus sampling, fetal transfusions, and, at fetal-care centers, in-utero intervention). The core skill is reasoning through the physiology of two patients at once and building a plan when the textbook doesn't have a clean answer.

Much of MFM is consultative. In many practices the MFM assesses risk, writes the plan, and returns the patient to the referring general OB, a genuinely different rhythm from generalist obstetrics. Other MFMs carry complex patients throughout pregnancy, run the antepartum service at a tertiary or quaternary center, and stay on the hook for high-acuity deliveries and OR emergencies. Same three letters; very different daily lives.

Representative procedures: detailed obstetric ultrasound and Doppler studies · amniocentesis · chorionic villus sampling (CVS) · fetal transfusion · management of complex deliveries and cesareans · (at fetal-care centers) fetoscopic and open fetal surgery, laser ablation for twin-twin transfusion.

A day in the life: A consult-heavy day runs largely on a schedule: a morning of anatomy scans and Doppler studies, a high-risk clinic where you counsel a patient with poorly controlled diabetes and a growth-restricted fetus, a genetics conversation after an abnormal screen, and consults phoned in by general OBs across your region. An inpatient/co-management day looks different: rounding on an antepartum service full of the sickest maternal transfers in the region, then being pulled into a crashing preeclamptic patient, a placenta accreta plan, or a previable delivery. Call is real, but for consultative roles it's often home call covering questions and transfers rather than the in-house L&D grind, while MFMs who deliver keep the 2 a.m. emergencies.

The training path & time to completion

Medical school (4 yrs) → OB/GYN residency (4 yrs) → MFM fellowship (3 yrs) → board-eligible in the MFM subspecialty. You reach MFM through OB/GYN: you must first be certified (or board-eligible) in OB/GYN before you can pursue MFM subspecialty certification.1

  • OB/GYN residency: 4 years, ACGME-accredited. This is the base specialty you match into from medical school; MFM is a fellowship layered on top.1
  • MFM fellowship: 3 years, ACGME-accredited (specialty code 230). Fellowship is frequently described as noticeably lighter than OB residency, with protected research and education blocks, and a scholarly or thesis requirement historically applies.12
  • Board: the American Board of Obstetrics and Gynecology (ABOG) grants subspecialty certification via a two-step process, a Qualifying (written) Examination followed by a Certifying (oral) Examination, plus the scholarly requirement. An osteopathic path exists via the AOBOG.1 ⟳
  • Total from the start of college: ~15 years (4 undergrad + 4 med school + 4 residency + 3 fellowship), a long runway, and three of those fellowship years delay full attending income against finishing at generalist OB.

How competitive is it?

The competitiveness question for MFM has two layers, and premeds usually only hear about the first.

Layer one: matching OB/GYN out of medical school. MFM is reached through an OB/GYN residency, so the first hurdle is matching OB/GYN, a solidly competitive but far-from-elite base specialty, and one that is comparatively open to DOs, who took 21.9% of the OB/GYN PGY-1 positions filled in the 2026 Match, relative to the surgical subspecialties.3

Layer two: matching the MFM fellowship. MFM is matched through the NRMP Specialties Matching Service (the OB/GYN fellowship match). In the 2026 appointment year: 110 programs, 166 positions offered, and 154 filled for a 92.8% fill rate, from 163 total applicants.4 ⟳

What that means for you:

  • Applicant-to-position ratio ≈ 0.98:1 (163 applicants for 166 positions), roughly one applicant per position at the pool level, with ~12 positions going unfilled. MFM is not oversubscribed the way some smaller OB/GYN subspecialties are; it is the largest OB/GYN subspecialty fellowship by position count.4 ⟳
  • US-MD-heavy pipeline: 73.5% of positions were filled by US MD graduates. Of the 163 applicants, 129 were US MD (122 matched), 16 US DO (15 matched), 7 US IMG (all matched), and 11 non-US IMG (10 matched).4 ⟳
  • The honest read online is that MFM fellowship is competitive but attainable for research-productive OB residents from a wide range of programs, where the scholarly and research output matters but you don't need an ultra-elite pedigree.5

Compensation — the robust version

A note on sources first: no single premier survey (Doximity, Medscape) publishes an MFM-specific line item; they report only "OB/GYN" in aggregate. The most reliable MFM-specific figures come from recruiting-firm placement data (AMN Healthcare, Barton Associates) and salary-aggregator models (Salary.com). MGMA tracks MFM as a distinct category but its subspecialty tables are paywalled and could not be directly accessed. Job-board scrapers that returned obviously corrupted figures (e.g., $96k averages, Canadian cities, single-submission samples) were excluded.678

National number. MFM total compensation clusters in the ~$510k–$561k range across credible 2025–2026 sources: $561,000 (AMN Healthcare placement data, 2025), $560k (Marit Health, 2026), $547,968 (Salary.com recruiting benchmark, May 2026), $531,456 (Salary.com physician benchmark, Jul 2026), and $513,000 (Barton Associates OB/GYN Salary Guide, 2026). A defensible "typical full-time" figure is ~$530k–$560k total compensation.6789 ⟳

Among the better-paid OB subspecialties, with a real premium over generalist OB. General OB/GYN runs about $389,566 (Doximity 2025) to $390,000 (Medscape 2026). MFM's premium over generalist OB is roughly +$120k–$170k, or +30–45%, putting MFM alongside gynecologic oncology and reproductive endocrinology (REI) at the top of the OB/GYN pay ladder.61011 ⟳

The spread (structure, Salary.com physician benchmark, Jul 2026): 10th pct $470,432 · 25th $499,514 · median $531,456 · 75th $585,981 · 90th $635,623 (avg hourly ~$256). The recruiting benchmark (May 2026) runs a touch higher: 10th $483,536 · median $547,968 · 90th $658,035 ($232–$316/hr).7 ⟳

Real-world outliers go higher. AMN Healthcare's filled permanent placements (trailing 12 months, 2025) ran $420k to $800k annually, the top position reaching $800k/yr. Practical spread: roughly $420k at the low/academic end to $650k–$800k at the high end (busy private high-volume or underserved-market roles).6 MGMA's MFM median is estimated ~$500k–$550k but the subspecialty table is paywalled, so treat it as unverified.8 ⟳

Seniority barely moves it, and the experience curve is flat. Even new MFM attendings command high floors given scarcity. Salary.com physician benchmark: entry (<1 yr) $518,584 to expert (>8 yr) $559,939, only a ~$40k–$55k lifetime lift. Fellow (in-training) salaries are separate, ~$70k–$85k GME stipends.7 ⟳

Geography, where the rural and underserved premium is the signature quirk shared with OB broadly. MFM pays more in the Midwest, South, and rural/underserved markets and less in coastal metros with dense academic supply. AMN's 2025 placements make it concrete: higher-need and lower-cost markets top out highest, at Odessa TX $600k–$625k and Shreveport LA $600k–$800k, while major metros sit mid-range at Chicago $500k and Ann Arbor $450k–$550k. This is driven by MFM maldistribution: the DC area has the highest MFM density while roughly 1 in 3 US counties lack any maternity care facility.612 ⟳

Academic vs. private. Academic MFM runs below private practice, commonly toward the $420k–$500k band, the low end of AMN's range and near the 10th–25th percentiles, consistent with academic OB/GYN generally trailing private. Private/hospital-employed MFM captures the higher figures ($550k–$800k), especially where the MFM runs a busy ultrasound/diagnostic unit and high-risk consult volume in an underserved market.613 ⟳

How you're actually paid. Income is built on several service lines: high-risk obstetric management (often the largest driver), obstetric ultrasound and diagnostic procedures, which are a significant and relatively predictable imaging-revenue component, consultative co-management, and call. Employed models increasingly tie total comp to wRVU production (the MFM wRVU benchmarks live in MGMA's paywalled data). Call structure is a key negotiation lever, since consult-only home call against in-house delivery call materially changes both the pay and the life, though no published national MFM call-pay benchmark was located. Locum tenens MFM runs ≈ $218/hr (Barton, 2026), generally more per hour than permanent plus travel/housing, with strong demand from coverage gaps in maternity deserts.69 ⟳

The trend that colors all of it. Only ~1,587 MFM subspecialists practiced nationally in 2022, against a projected shortage of nearly 9,890 OB/GYNs by 2037 and ~1 in 3 counties with no maternity care. All three counts reach this page through a locum tenens staffing agency, Barton Associates, which sells the coverage whose scarcity it is reporting, and which credits the 1,587 to SMFM without linking it. Weigh them accordingly. That scarcity keeps MFM comp floors high, drives the rural/underserved premium, and supports a strong locum market, while the growth of fetal-care centers adds high-value procedural revenue lines.12 ⟳

Lifestyle & the practice-model bargain

The single most important thing to understand about MFM lifestyle: the practice model drives everything, and two very different jobs share the same name.14

  • Consultative and outpatient-heavy MFM is largely schedulable: ultrasound units, high-risk clinics, antepartum consults, and genetics counseling. In consult-only models you assess risk, write the plan, and hand the patient back to the referring OB. This is why MFM is often pitched as "the OB subspecialty with better hour control," and it's genuinely more controllable than generalist obstetrics.14
  • Co-management / inpatient / laborist-adjacent MFM keeps you managing complex patients throughout pregnancy, running the antepartum service, and on the hook for high-acuity deliveries and OR emergencies: crash C-sections, hemorrhage, previable deliveries at 2 a.m. Here the call is still brutal at times.14

MFM sits on top of OB/GYN, one of the more call-heavy and unpredictable base specialties (babies don't schedule themselves), but the shape of the work is meaningfully different and, in many practices, more controllable. Call is often home call covering questions and transfers rather than in-house L&D, especially in consultative roles. Academic MFM brings more ultrasound/consult volume, research, teaching, and protected time, but also tertiary-center acuity, since the sickest maternal transfers land on you. The job you take shapes your life more than the specialty label does.

Lifestyle rating: 3/5. Better schedule control than generalist OB for many, particularly in consult/imaging-heavy roles, but still tethered to a field where the worst emergencies are time-critical and can't be deferred. Not a "clinic closes at 5, phone off" life.

Wellbeing — the part to take seriously

Burnout is real and non-trivial. A survey of SMFM members (Am J Perinatol, 2019) found a burnout rate around 56%, which the authors flagged as higher than many other specialties. For cross-specialty scale on a different instrument, the AMA's 2025 Organizational Biopsy puts parent OB/GYN at 45.7% against a 41.9% all-physician average, fourth of the nine specialties it names as most burned out. The named drivers: 5–20 years in practice, more than 4 hours of daily charting, and career/supervisor dissatisfaction. Protective factors: protected education time and regular exercise. Notably, women reported higher emotional exhaustion and depersonalization and lower personal accomplishment than men, a gender gap the authors couldn't fully explain and flagged for further study.15 ⟳

But high meaning, too. Research on compassion fatigue and satisfaction in US MFM physicians (2021–2023) frames the field as both high-emotional-labor and high-compassion-satisfaction: the same intensity that wears people down is also what makes the work feel deeply worth it for those wired for it.16 ⟳

The emotional weight is distinctive, and it is a defining feature rather than a footnote. MFM concentrates some of the hardest conversations in medicine: diagnosing lethal or severe fetal anomalies, counseling on termination for medical reasons, managing stillbirth and previable delivery, and shepherding families through outcomes nobody can fix. You are frequently the person delivering the worst news of someone's life, and then continuing to care for them through it. It's a genuine reason some people love the field and a genuine reason others leave it.

Career longevity. OB/GYN broadly lands mid-pack on Medscape "would choose again" and happiness metrics, and MFM skews toward people who wanted the acuity, which tends to correlate with staying. Longevity is generally solid, though the charting burden, the litigation climate of obstetrics, and the emotional load are the classic reasons people scale back toward outpatient and ultrasound-heavy roles over time, the built-in off-ramp within the field.17 ⟳

Who's in the field (demographics)

  • Women: OB/GYN is the most female specialty in medicine, and ACGME's own list of the specialties with the highest share of female residents opens with it: 88.2% of OB/GYN residents in academic year 2024-25. Active OB/GYN physicians rose from 60.5% (2021) to 64.1% (2024) as the older, more male cohort retires. Because MFM draws from that pool, the MFM fellow cohort is likewise strongly female-majority, though eight points behind the residency: 357 of the 445 MFM fellows in academic year 2024-25 were women, or 80.2%. The sibling OB/GYN fellowships sit in the same band, with urogynecology at 83.4%, reproductive endocrinology at 80.4% and gynecologic oncology at 79.6%, and complex family planning far above all of them at 98.5%.181920 ⟳
  • DO: ~9.8% of 2026 MFM applicants, against 13.6% across all ACGME subspecialty programs, consistent with OB/GYN being a predominantly US-MD pipeline. Compare the like-for-like figure instead and the field looks narrower still: 7.4% of MFM's own 445 fellows are osteopathic graduates.420 ⟳
  • IMG: ~11.0% combined (US IMG and non-US IMG) of 2026 MFM applicants, against 31.7% across all ACGME subspecialty programs — a gap of twenty points, and the widest of MFM's demographic gaps. MFM's own fellow class is 7.0% international graduates against 85.4% US MD.420 ⟳
  • URiM: Black and Hispanic/Latino trainees are under-represented in MFM relative to the US population, per peer-reviewed work on OB/GYN subspecialty diversity; no primary source publishes current MFM-specific percentages. National physician-workforce context (all specialties, 2024): 56.1% White, 19.8% Asian, 6.7% Hispanic/Latino, 5.3% Black.1921 ⟳

Culture, personality & the online stereotypes

Who gravitates here: OB/GYNs who love the highest-acuity obstetrics and don't want to give it up, the ones energized by a crashing preeclamptic patient or a complex placenta accreta plan. It also draws the physiology-and-puzzle crowd within OB (people who like the medicine of pregnancy, meaning cardiac disease in pregnancy, coagulopathy, and fetal growth), plus those drawn to imaging (detailed obstetric ultrasound) and to genetics and prenatal diagnosis. A recurring self-description: the OB who wanted the "internal medicine of obstetrics." As always, plenty of people in the field do not fit any single mold.1422

The stereotypes. community caricatures, attributed to reputation not fact. Plenty of mfms don't fit them:

  • "The brains + the high-risk of OB." The reputation casts MFM as the cerebral, physiology-heavy subspecialty of the field, reasoning through complex cases and reading imaging. Real kernel: the intellectual "consult" identity is genuine; the caricature undersells how much hands-on and emotional work is involved.
  • "MFM fixed the lifestyle." Online, the read is that MFM is one of the more lifestyle-improving OB subspecialties, but people caution repeatedly that "consultative and chill" and "running the antepartum service at a quaternary center" are wildly different jobs. The upgrade is real but conditional; nobody online pretends the emergencies disappeared.
  • "A well-paid OB subspecialty." Broadly accurate, and MFM is viewed as a solid financial step up from generalist OB, especially in ultrasound/consult-heavy private roles.

What people say online (synthesized and paraphrased, not quotes): Across trainee and physician forums the common read is that MFM meaningfully improves lifestyle relative to residency, largely because of the scheduled ultrasound and consult component, but with a loud, repeated caveat that the job varies enormously by practice model. Fellowship is described as competitive but attainable for research-productive OB residents, and generally lighter than residency. Threads emphasize the emotional side heavily: the field is respected as intellectually rich and well-compensated, but people warn that the anomaly and loss counseling is not something to underestimate, and that a chunk of daily work in some roles is repetitive scanning. The overall sentiment is cautiously positive, with a consistent through-line: great if you actually love high-risk OB and imaging; a mistake if you're doing it just to escape general OB call.

Voices from the field. Paraphrased from public writing, with links to the originals:

  • MFM physician Alan Peaceman lays out that not every high-risk pregnancy needs an MFM, and that MFMs split between consult-only (assess, plan, hand back) and full co-management models, the core lifestyle fork of the field.14
  • MFM researchers Thomas McElrath and Kara Rood illustrate the physiology-puzzle, research-forward side of the culture, digging into placental disease and biomarkers behind preeclampsia, the "cerebral" reputation in practice.23
  • An SMFM member survey documents the ~56% burnout rate, the unexplained gender gap in exhaustion, and protective factors (protected education time, exercise).15
  • A cross-sectional analysis of MFM physicians frames the field's defining duality of high emotional labor alongside high compassion satisfaction.16

Why people choose it / why people leave

Why choose it: you genuinely love high-acuity obstetrics and the physiology of complicated pregnancy, and don't want to trade it for gyn or office work · you want the intellectual "consult" identity within OB, reasoning through complex cases, imaging, and genetics · a meaningful pay bump and strong, geographically broad demand relative to generalist OB · more schedule control available in consultative/outpatient roles · deep meaning in walking families through the hardest pregnancies · a built-in ability to dial toward more schedulable ultrasound/consult work as your career matures.

Why leave or avoid it: the emotional load of anomalies, loss, termination counseling, and previable deliveries is relentless and not for everyone · burnout is common, and the charting burden and obstetric litigation climate grind on people · if you're choosing MFM mainly to escape OB call, plenty of MFM jobs keep you deep in high-stakes deliveries and emergencies · a large fraction of daily work in some roles is repetitive ultrasound scanning · the training runway is long (7 years post-MD).

Best fit if: you're an OB/GYN who lights up at the sickest patients · you like physiology puzzles and imaging · you tolerate, and even find meaning in, heavy emotional labor · you want a subspecialty that can be tuned toward more schedulable outpatient work over time.

Not for you if: you want predictable, low-acuity, low-emotional-weight hours · you dislike ultrasound · you're conflict- or loss-averse in high-stakes counseling · you're lukewarm on obstetrics and drawn only by the pay.

The FLI angle — Maternal-Fetal Medicine for first-gen, low-income & immigrant students

Where MFM fits FLI realities well:

  • High pay, high demand, strong job security. MFM is one of the better-paid OB subspecialties (~$530k–$560k typical, with senior/tertiary and imaging-heavy roles into the $600k–$800k range), and demand is strong and geographically broad, since maternal health is a national priority and MFMs are chronically needed. For someone who needs the career to land financially, that's real leverage.
  • Reachable through a standard OB/GYN residency. You don't need an ultra-elite pedigree to match OB/GYN, and the MFM fellowship, while competitive, is attainable for research-productive residents from a wide range of programs. The path is demanding but not gate-kept the way the most closed fields are.
  • Geographic flexibility with an underserved premium. The highest-paying MFM jobs cluster in higher-need, lower-cost markets (roughly 1 in 3 US counties lack any maternity care), so you can often earn the most while practicing near family or in the kind of community you came from.

Risks to name honestly:

  • The time cost is steep. Four years of OB/GYN residency plus three of fellowship means full attending income is delayed three years versus finishing at generalist OB. If you're supporting family or carrying financial pressure, that delay is not abstract.
  • The emotional load isn't free money. The day-to-day weight of loss, anomalies, high-stakes counseling, and previable deliveries, plus a ~56% burnout rate, is genuinely hard to sustain. MFM rewards people who actually want this work, not people using it as a paycheck strategy.
  • DO and IMG access is modest. The MFM pipeline is predominantly US-MD, at DO ~10% and IMG ~11% of applicants, so it is reachable but a tighter door than the most open fields.

Bottom line: For an FLI student who genuinely loves high-risk obstetrics and imaging, MFM is one of the better risk-adjusted bets in medicine: high, portable pay, strong demand, and a real path in through general OB/GYN. But it comes bundled with a long training runway and a permanent, distinctive emotional burden. If you're lukewarm on obstetrics, the time and emotional cost is steep, so shadow both a busy L&D service and an MFM ultrasound clinic before you commit.

Subspecialties & sub-focuses within MFM

MFM is already a subspecialty, but the field has recognizable sub-focuses that shape a career. None are separate boards; they're where an MFM concentrates.24

  • Fetal intervention / fetal surgery. The most specialized, tertiary/quaternary-only corner: in-utero repair (open and fetoscopic, e.g., MOMS-trial-style spina bifida repair), laser ablation for twin-twin transfusion syndrome, and fetal transfusion. Elite, referral-based, concentrated at named fetal-care centers, rather than most MFMs' daily work.
  • Obstetric ultrasound. A huge, schedulable, well-reimbursed slice: detailed anatomy scans, Dopplers, growth surveillance. The backbone of the "consultative, better-hours" MFM job.
  • Genetics / prenatal diagnosis. Counseling on aneuploidy screening, carrier status, and anomalies; heavy overlap with genetic counselors; a core intellectual and emotional-labor domain.
  • Research / academic MFM. Placental biology, preeclampsia biomarkers, prematurity; the physiology-forward, protected-time track that anchors the field's cerebral reputation.

Fun facts

  • MFM = "perinatology". Practitioners are often called perinatologists.
  • MFMs are the ones who perform and interpret the detailed anatomy ultrasound and the prenatal diagnostic procedures like amniocentesis and CVS.
  • The frontier of the field is fetal intervention and surgery, meaning in-utero procedures for conditions like spina bifida, twin-twin transfusion (laser), and fetal anemia (transfusion), concentrated at a handful of fetal-care centers.
  • Preeclampsia, one of MFM's signature diseases, remains a genuine research frontier in placental biology and biomarkers, part of why the field carries a cerebral reputation.
  • OB/GYN, MFM's parent specialty, is the most female field in medicine, at 88.2% of residents in academic year 2024-25.
  • "MFM" describes both an easygoing outpatient ultrasound consultant and a quaternary-center antepartum intensivist — same three letters, very different daily lives.

Salary.com MFM benchmarks — physician benchmark (Jul 2026) median $531,456, percentiles 10th $470,432 / 25th $499,514 / 75th $585,981 / 90th $635,623, avg hourly ~$256, experience curve $518,584→$559,939; recruiting benchmark (May 2026) median $547,968, 10th $483,536 / 90th $658,035, $232–$316/hr. https://www.salary.com/research/salary/benchmark/physician-maternal-fetal-medicine-salary ; https://www.salary.com/research/salary/recruiting/maternal-fetal-medicine-salary On Salary.com: its CompAnalyst benchmark is HR-reported employer survey data blended with job-posting data, not a physician panel. It is base-weighted and so runs low against total-compensation surveys, and it is used here for percentile structure rather than for levels. ↩ ↩2 ↩3 ↩4

  8. MGMA Provider Compensation 2024/2025 — MFM tracked as a distinct category ("OB/GYN: Maternal and Fetal Medicine") but the subspecialty table is paywalled, so the ~$500k–$550k median is an estimate rather than a published MGMA figure. https://www.mgma.com/2025-provider-compensation ↩ ↩2 ↩3

The figure quoted here comes from the self-reported panel, not from either benchmark. Read it as crowd data: unweighted, of unstated sample size, and directional. ↩ ↩2

  12. MFM workforce/shortage — ~1,587 practicing MFM subspecialists (2022 count cited by Barton/SMFM); projected ~9,890 OB/GYN shortage by 2037; ~1 in 3 US counties lack maternity care; DC-area highest MFM density. Barton Associates, "Is Locum Tenens Perinatology Right for You?" (2025/2026). https://www.bartonassociates.com/blog/maternal-fetal-medicine-jobs-is-locum-tenens-perinatology-right-for-you/ Corrected 2026-08-17: the publisher is now named in the body rather than only here. Barton Associates is a locum tenens staffing agency, so it sells the labor whose scarcity it is reporting. This site keeps the figures and names the seller in the visible sentence, which is the same answer it gives for relay hosts. The rule that no seller publishes a price this site quotes governs prices, and it does not reach a workforce count. Barton attributes the 1,587 to SMFM but publishes no link to it, so the count stays attributed to Barton. ↩ ↩2

MFM is not broken out separately in either report. ↩

  18. AAMC, "What's your specialty?" (2021 data) — OB/GYN residents/fellows 86.4% women (highest of any specialty); active OB/GYN 60.5% women (2021). https://www.aamc.org/news/what-s-your-specialty-new-data-show-choices-america-s-doctors-gender-race-and-age. Corrected 2026-08-17: the ~86% figure was three academic years old and was carried undated in the dashboard, the body and Fun facts, and it composited residents with fellows, which differ by eight points. ACGME's AY2024-25 book puts OB/GYN residents at 88.2% and MFM fellows separately at 80.2%, so the resident figure is now stated with its year and the fellow figure is stated on its own. The "most female specialty in medicine" claim is unaffected and ACGME confirms it independently, naming OB/GYN first on its list. This footnote is kept for the 2021 active-physician figure, which is the trend line the body uses. ↩

  19. AAMC "2025 Key Findings" (2024 data) — active OB/GYN 64.1% women; national physician-workforce race/ethnicity 56.1% White, 19.8% Asian, 6.7% Hispanic/Latino, 5.3% Black. https://www.aamc.org/data-reports/data/2025-key-findings ↩ ↩2

  20. ACGME, "2024-2025 Statistics on Graduate Medical Education" — ~114 accredited MFM programs (2024–2025). Corrected 2026-08-17: this footnote labeled 57.8% US MD / 22.5% IMG / 19.6% DO as "all-fellowship averages," and they are ACGME's figures for its 137,432 residents in specialty (core residency) programs. The book says in the next sentence that "the distribution by medical school type is slightly different in subspecialty programs," and then gives the subspecialty numbers verbatim: of 29,651 active subspecialty residents, 54.4% are US allopathic graduates, 31.7% international graduates, 13.6% osteopathic graduates and under 1% Canadian. The mislabel was the comparison baseline for the DO and IMG bullets and for the dashboard row. Both comparisons survive in direction and change in size: against the real fellowship averages MFM's DO gap narrows from about ten points to four, and its IMG gap widens from twelve points to twenty-one. The like-for-like comparison, MFM's own fellow class against other fellow classes, is in Table C.15 of the Data Resource Book: maternal-fetal medicine, 445 fellows, 380 US LCME graduates (85.4%), 31 international (7.0%), 33 osteopathic (7.4%), 1 Canadian (0.2%). https://www.acgme.org/newsroom/2026/1/acgme-releases-2024-2025-statistics-on-graduate-medical-education-programs-and-resident-physicians/ ; ACGME 2024-2025 Data Resource Book https://www.acgme.org/globalassets/pfassets/publicationsbooks/2024-2025_acgme_databook_document.pdf. The same Data Resource Book gives the sex split by fellowship: maternal-fetal medicine 114 programs, 445 fellows, 357 women (80.2%); urogynecology and reconstructive pelvic surgery 83.4%; reproductive endocrinology and infertility 80.4%; gynecologic oncology 79.6%; complex family planning 98.5%; parent obstetrics and gynecology 88.2% of 6,178 residents. Corrected 2026-08-17: the demographics section and the dashboard both said no primary source publishes an exact percentage for MFM fellows, and the figure is in the volume this footnote already cites for the MFM program count. The dashboard row had to read "MFM fellows female-majority" because of that stated absence; it now reads 80.2%. ↩ ↩2 ↩3

OB/GYN subspecialty diversity — Rincon et al., "Sex and Racial/Ethnic Diversity in Accredited Obstetrics and Gynecology Specialty and Subspecialty Training in the United States," 2021 (documents MFM fellows female-majority and Black and Hispanic/Latino trainees under-represented; its own percentages sit behind the paywall, and the current fellow-level sex split is published free in the ACGME Data Resource Book cited at 20, so nothing on this page depends on the paywalled text). https://www.sciencedirect.com/science/article/abs/pii/S1931720421003755 ; "Diversity elements on maternal-fetal medicine fellowship websites," 2023 https://www.sciencedirect.com/science/article/pii/S2666577823000722 ↩
