We are glad to be back and hope everyone had a great Fourth of July! On to tonight’s stories: the biggest study yet clears Tylenol in pregnancy, Planned Parenthood’s ban lapses, Illinois rewards menopause training, and more.

p.s. Trivia is back and it’s got an animal spirit (scroll to see) 🐾

THE LARGEST STUDY YET FINDS NO TYLENOL-AUTISM LINK

A sibling-matched analysis of more than 700,000 Hong Kong mother-child pairs found no association between acetaminophen use in pregnancy and autism, ADHD, or intellectual disability, at any trimester, dose, or frequency. Published in JAMA Internal Medicine by teams at the University of Hong Kong and Aston University, the study compared siblings to strip out the genetic and household factors that muddied earlier research. The results line up with large Swedish and Japanese datasets, and cut directly against the Trump administration's September claim tying Tylenol to autism.

THE PLANNED PARENTHOOD BAN QUIETLY EXPIRED

The one-year ban Republicans wrote into last summer's budget bill lapsed July 4, meaning Planned Parenthood can once again bill Medicaid again for contraception, cancer screenings, and STI care (but not abortions). The damage is already done, with roughly 30 clinics closing during the freeze, nearly all in contraceptive deserts and two-thirds in rural or medically underserved communities. Medicaid visits to the network fell 25%, per The Hill. Anti-abortion leaders are already pressing Congress to re-defund the group in a third reconciliation package.

ILLINOIS BECOMES THE FIRST STATE TO REWARD MENOPAUSE TRAINING

Starting January 1, any licensed Illinois clinician can count perimenopause and menopause coursework toward the implicit-bias training the state already requires for license renewal, under a bill the legislature passed unanimously in late May. It's the first state to build that incentive, and the gap it targets is stark: fewer than 200 Illinois physicians are certified menopause specialists, and roughly 70% of women who seek menopause care nationally never get treated. Ten states and DC now have menopause laws on the books, with some 60 more bills introduced this year.

AT HOME, DIY TRANSVAGINAL ULTRASOUND

Guided only by a remote sonographer on the phone, 263 women performed their own transvaginal ultrasounds at home, and the images met diagnostic standards 96% of the time, matching in-clinic rates. Blinded physicians trying to tell home scans from clinic scans guessed right just 56% of the time. Participants strongly preferred the at-home version to lying in an exam room, an appealing prospect for the many women who find the exam invasive or live nowhere near an OB/GYN. The JAMA Network Open trial was funded by the device's maker, Turtle Health.

YOUR OVARIES MAY NOT RETIRE AFTER MENOPAUSE AFTER ALL

Biologists have long assumed that once the eggs run out, ovaries shrivel into inert tissue. A mouse study suggests something else: aged ovaries fill up with immune cells and switch on inflammation genes, as if the organ is reinventing itself into an immune outpost once it's done reproducing. If this is true in human women too, it could help explain why autoimmune conditions like rheumatoid arthritis climb after menopause, and it reframes an organ medicine has mostly ignored post-fertility. Big caveats: this is early work in mice, and the Northwestern team is clear it doesn't yet mean anything for human health.

Here are the most interesting items we saw this week in women's health:

💰 FORTY-TWO PERCENT OF WOMEN CAN AFFORD THEIR CARE. FOR MEN, IT'S FIFTY-SEVEN. The West Health-Gallup Healthcare Affordability Index just recorded the widest gender gap since it launched in 2021 — and women dropped six full points in a single year. This isn't just a data point. It's a measure of how many women are skipping prescriptions, delaying appointments, and going without care they know they need. The affordability crisis has a gender, and it's getting worse.

🏥 MEDICAID'S MATERNITY DIRECTORIES ARE FULL OF DOCTORS WHO WON'T SEE PATIENTS. A federal watchdog audited Medicaid provider directories and found pregnant patients calling OB-GYNs who had moved, retired, or stopped accepting Medicaid. These ghost networks aren't an inconvenience — they're a barrier to prenatal care at the start of a pregnancy, when it matters most. Medicaid covers more than 40% of US births. States are required to fix this. Most don't.

🤢 SEVERE PREGNANCY NAUSEA TRACKS WITH A STRING OF DELIVERY COMPLICATIONS. A Stanford study of 2.5 million California births found that women hospitalized for hyperemesis gravidarum — the kind of pregnancy nausea that causes dangerous weight loss and dehydration — had a 25% higher risk to deliver preterm, 37% higher to be anemic, and 18% higher likely to develop preeclampsia. It's been dismissed as bad morning sickness for too long. This research says it should flag a pregnancy for closer monitoring from the start.

Editor’s note: We will be out next week for summer vacation! Our next edition will come on Tuesday, July 7. Have a wonderful Fourth of July!

p.s. How many OBGYNs get menopause training in residency? Try your luck on our trivia question below.

ABORTION BANS MAY BE A $68 BILLION DRAG ON THE ECONOMY

The 16 states with abortion bans or severe restrictions cost the US economy about $68 billion a year, according to an Institute for Women's Policy Research analysis. They also found women lost earnings at more than $140 billion in 2025, up $7 billion from its 2024 estimate. The model ties most of the loss to women pushed out of the workforce or into lower-paying work. Lifting the restrictions, it estimates, would draw roughly 325,000 more women into the labor force each year, with Black and Latina women absorbing the steepest costs.

ABORTIONS KEPT RISING AFTER THE BANS

Four years after Dobbs, the count of abortions in America has gone up every year, even as more states banned the procedure, NPR reports on the anniversary of the Supreme Court decision. The driver is medication abortion mailed across state lines under shield laws, which has largely offset the closure of clinics in ban states. The result is a map where the legal status of abortion and the actual availability are quite different.

THE FERTILITY BENEFIT WITH A SIX-FIGURE CEILING

A proposed federal rule would let employers offer fertility coverage as an "excepted benefit," a separate side policy capped at $120,000 over a worker's lifetime. Critics warn that because excepted benefits sit outside the Affordable Care Act, they can implement things like the very dollar cap the ACA bans, leaving patients with fewer protections if a costly IVF cycle blows past the limit. Backers say it gives companies an easier path to add IVF coverage. The rule is open for comment through July 13 and, if finalized, takes effect for 2027 plans.

THE CERVICAL PROCEDURE YOU MAY NOT NEED RIGHT AWAY

Women with moderate cervical precancer often have a procedure known as LEEP, which cuts out a cone of cervical tissue (and is linked later to preterm birth). National Cancer Institute researchers found that cutting it out within six months did not lower three-year cancer risk compared with watchful monitoring. They analyzed data from over 12,000 women. This isn't about skipping colposcopy, which continues either way. It's that for many women, careful follow-up is a reasonable alternative to immediately removing tissue.

MOST IVF EXTRAS STILL LACK GOOD EVIDENCE

Many fertility clinics offer optional IVF "add-ons" — extra tests, procedures, medications, or techniques sold alongside a standard IVF cycle in hopes of improving the chance of having a baby. But a new review of clinical trials found little evidence that most actually work. Researchers found only weak evidence supporting three commonly offered add-ons (EmbryoGlue, endometrial scratching, and physiological ICSI), while the rest either showed no benefit or lacked enough high-quality data to draw conclusions. The authors say patients need clearer, independent information before paying for treatments that can add thousands of dollars to an already expensive IVF journey.

Tonight: a record gender gap in who can afford care, Medicaid's maternity ghost networks, and more.

— Meghan McCarthy

p.s. Trivia is back and it has to do with one of tonight’s stories 👀

FORTY-TWO PERCENT OF WOMEN CAN AFFORD THEIR CARE. FOR MEN, IT'S FIFTY-SEVEN.

Americans' ability to pay for healthcare and medicine fell to a five-year low this spring, and the gender gap is the widest this index has recorded: 42% of women are "cost secure" versus 57% of men. Women dropped six points in a single year. The West Health-Gallup reading, drawn from a 5,660-person panel, found the erosion concentrated among women, lower-income households, and people under 50.

MEDICAID'S MATERNITY DIRECTORIES ARE FULL OF DOCTORS WHO WON'T SEE YOU

A federal watchdog audited Medicaid provider directories and found pregnant patients calling OB-GYNs who had moved, retired, or stopped taking the insurance entirely. These "ghost networks" leave mothers on Medicaid, which pays for more than 40% of US births, hunting for prenatal care that exists only on paper. The HHS inspector general's office flagged the directories as a barrier that states are required to fix, but rarely do.

OREGON IS SPENDING $37 MILLION TO KEEP RURAL DELIVERY ROOMS OPEN

As rural maternity wards close across the country, Oregon lawmakers set aside $37 million to prop up the ones still standing, paying hospitals to keep labor-and-delivery units running in counties where the nearest alternative can be hours away. InvestigateWest reported the state is hoping that direct subsidies can slow a national wave of closures and the Trump administration’s Medicaid cuts. The same pressures have shuttered delivery units in dozens of rural counties.

SEVERE PREGNANCY NAUSEA TRACKS WITH A STRING OF DELIVERY COMPLICATIONS

Hyperemesis gravidarum, the extreme nausea and vomiting that can cause dehydration and dangerous weight loss, is linked to a cluster of pregnancy complications, a Stanford team found in 2.5 million California births. Women hospitalized for it were about 25% more likely to deliver preterm, 37% more likely to be anemic, and 18% more likely to develop preeclampsia. Around 2.2%—some 53,700 women—had the condition, and the researchers argue it should flag a pregnancy for closer monitoring rather than be dismissed as ordinary morning sickness.

AN AI THAT WATCHES YOUR MAMMOGRAMS OVER TIME FLAGS CANCER EARLY

An algorithm that compares a woman's mammograms across years, rather than reading each in isolation, predicted future breast cancer risk more accurately than current risk models, a Radiology study of 54,014 women reported. Tracking subtle changes across 158,807 mammograms, it spotted patterns preceding 817 diagnoses. One caveat worth naming: the senior author runs a company commercializing exactly this kind of AI risk tool.

Here are the most interesting items we saw this week in women's health:

💊 ALABAMA'S MONTHLY PREGNANCY TESTS FOR CANNABIS PATIENTS. Alabama now requires women ages 11 to 50 to pass a pregnancy test in a doctor's office every 30 days to keep accessing medical cannabis. No other state has built routine pregnancy surveillance into medical cannabis access. Patients pay for each test themselves.

🩺 THE MENOPAUSE BOOM HAS A FORGOTTEN WAITING ROOM. As hormone therapy gets marketed online as a midlife fix, women who medically can't take it because of breast cancer, clotting disorders, or heart risks say they feel cut off from the whole conversation. Nonhormonal options exist, including newer drugs fezolinetant and elinzanetant, but many doctors don't raise them and patients don't know to ask.

💪 TWO HOURS OF WEIGHTS, 44% LOWER HEART ATTACK RISK. Women who did at least two hours of strength training a week had a 44% lower risk of heart attack than women who did none, an analysis of around 117,000 nurses found. Each additional hour tracked with led to an additional 14% drop in risk, and the benefit held even among women already meeting aerobic exercise targets.

FATHERS' MENTAL HEALTH DIDN'T MOVE. MOTHERS’ DID.

After Texas banned abortion in 2021, the share of mothers reporting fair or poor mental health nearly doubled, from 4.6% to 9.3%, far outpacing the rise in states without bans. The Harvard-led analysis of around 157,000 mothers found the effect held whether or not a woman was pregnant or seeking an abortion, and hit mothers on public insurance hardest. Fathers' mental health didn't budge. The authors can't prove cause, but point to a fraying reproductive health system: clinicians leaving, maternity care access shrinking, and reproductive autonomy reduced.

TWO HOURS OF LIFTING, 44% FEWER HEART ATTACKS

Women who did at least two hours of strength training a week had a 44% lower risk of heart attack and a 20% lower risk of major cardiovascular disease than women who did none, an American College of Cardiology journal analysis of around 117,000 nurses found. Each additional hour tracked with a further 14% drop in heart attack risk, and the benefit held even among women already meeting their aerobic exercise targets. The study is observational, but heart disease remains the leading killer of women, and resistance training is still the prevention tool most often left out of the conversation.

THE WOMEN ON HORMONE THERAPY ARE HEALTHIER. BUT THE HORMONES MIGHT NOT BE WHY.

A survey of more than 10,000 women found that menopausal women on hormone therapy ate more produce, slept better, and were likelier to strength train than women who'd never used it. But the study's own society medical director, Stephanie Faubion, says the explanation is mostly "healthy-user bias": women who choose hormone therapy tend to be more proactive about their health to begin with, with greater access to care and more resources. It's the same confound that made early hormone studies look heart-protective before randomized trials said otherwise.

PREECLAMPSIA'S WARNING DOESN'T END AT DELIVERY

Women who had preeclampsia with moderate to severe protein in their urine were about five times as likely to develop chronic kidney disease within a decade as those with little or none, roughly 1 in 20 versus 1 in 100, a Danish population study found. They also had higher rates of lasting high blood pressure. The only cure for preeclampsia is delivery, and monitoring typically stops at delivery, right when the long-term risk is just beginning.

A HISTORY OF THE FEMALE BODY, WRITTEN IN THE MARGINS

In "Presence," historian Erin Maglaque reconstructs what it felt like to inhabit a woman's body in Europe from 1500 to 1800: beauty ideals that swung from fertility to restraint, pregnancy cravings believed to shape the fetus, and "greensickness," the period's name for teenage longing with nowhere to go. Her problem is the archive itself, which preserved almost nothing of women's interior lives. Much of what the modern West treats as natural about the female body, the review argues, was invented in those centuries.

Tonight: Alabama wants monthly proof you're not pregnant before you can fill specific prescriptions, the forgotten waiting room of the menopause boom, and more.

ALABAMA WANTS MONTHLY PROOF YOU'RE NOT PREGNANT

Alabama now requires women ages 11 to 50 to pass a pregnancy test in a doctor's office every 30 days to keep using medical cannabis, unless they can prove they've had surgery that makes pregnancy impossible. No other state has built this kind of routine pregnancy surveillance into medical cannabis access. Physicians are barred from certifying anyone pregnant, breastfeeding, or "attempting to conceive," and patients pay for each in-office test themselves. Alabama leads the country in jailing pregnant women over drug use and is one of three states that apply child-endangerment laws to pregnancy.

THE MENOPAUSE BOOM HAS A FORGOTTEN WAITING ROOM

The New York Times reports that as hormone therapy gets marketed online as a midlife miracle, the women who medically can't take it, because of breast cancer, clotting disorders, or heart risks, say they feel cut off from the whole conversation. The frustration is compounded due to a lack of provider knowledge: nonhormonal options exist, including the newer drugs fezolinetant and elinzanetant, cognitive behavioral therapy, and vaginal estrogen, but many doctors don't raise them and patients don't know to ask. The Menopause Society's medical director says the toolkit is far bigger than the marketing suggests. Hormone therapy is only approved to treat hot flashes, night sweats, and bone loss, not the longer list influencers attach to it.

WE KNOW HOW TO STOP THE LEADING CAUSE OF MATERNAL DEATH. WE OFTEN DON'T.

Postpartum hemorrhage kills around 43,000 women a year and remains the leading cause of maternal death, yet a three-part Lancet series argues most of those deaths are preventable with tools that already exist. NPR dives into how it could work, starting with measuring blood loss in a calibrated drape instead of eyeballing it, which misses roughly half of hemorrhages. The next step is moving fast on a bundle of uterine massage, medication, and IV fluids. Across a trial of more than 200,000 women in four African countries, that approach sharply cut severe bleeding. One WHO author's estimate: used consistently, what we have now could prevent more than 95% of these deaths.

TURNS OUT IT WAS NEVER ABOUT CYSTS

Washington Post’s Leana Wen looks at why polycystic ovary syndrome is being renamed polyendocrine metabolic ovarian syndrome, or PMOS—a change 56 medical societies signed onto. The old name was a double misnomer: the "cysts" are actually normal ovarian follicles, and the disorder originates in the endocrine system, not the ovaries. That reframing matters because the condition, which affects roughly one in seven women of reproductive age, drives insulin resistance and raises the risk of diabetes, heart disease, and endometrial cancer. Advocates hope the new name finally pushes doctors to screen for those risks starting in adolescence.

THE DRUG THAT "FAILED" MAY HAVE JUST BEEN AVERAGED AWAY

An investigational brain drug delivered as a nasal spray reached the brain in different amounts depending on sex and, in women, on where they were in their menstrual cycle, Tel Aviv University researchers found in mice and a small group of healthy adults. Female mice absorbed more when estrogen peaked. The authors argue that averaging results across men and women can bury a real effect, one reason a promising therapy can look like a flop in trials. Their point: hormones and cycle timing belong at the center of how brain drugs are designed and dosed, not treated as noise.

Here are the most interesting items we saw this week in women's health:

📊 Birth control has ranked as the single most morally acceptable behavior Gallup tracks every year it's been polled. This year it's at a record low: 83% of Americans call it acceptable, down from 90% last year. Independents drove the slide, losing 11 points in a single year.

🏛️ Rep. Marie Gluesenkamp Perez told the House she lost a pregnancy at 11 weeks, and the medication to pass the miscarriage left her in pain "worse than" delivering her son four years ago. Her amendment directing the NIH to study better pain management for miscarriage passed unanimously.

💉After the CDC dropped its COVID-in-pregnancy recommendation last year, ACOG issued its own immunization schedule for pregnant and postpartum patients, endorsed by 13 medical groups. ACOG said it withdrew from the CDC's vaccine committee over "concerns about recent changes that undermine the committee's scientific integrity."

MISCARRIAGE PAIN IS BARELY STUDIED. A CONGRESSWOMAN IS TRYING TO CHANGE THAT.

Rep. Marie Gluesenkamp Perez told the House she lost a pregnancy at 11 weeks, and that the medication to pass the miscarriage left her in pain "worse than" delivering her son four years ago. Her amendment directing the NIH to study better pain management for miscarriage was passed unanimously. The issue is complicated — Republicans want to take away telehealth prescribing for the abortion pill (despite its record of safe use) and may see this as bolstering their argument. But the congresswoman is focused on a common refrain in women’s health: why doesn’t our pain matter?

OB-GYNS BREAK WITH THE CDC ON VACCINES (FOR OBVIOUS REASONS)

It’s not a shock, but for the American College of Obstetricians and Gynecologists issued its own immunization schedule for pregnant and postpartum patients instead of following CDC guidance (or lack thereof). This comes after the agency replaced its COVID-in-pregnancy recommendation with "no guidance" last year. Endorsed by 13 medical groups, ACOG urges flu, Tdap, COVID, and RSV protection at any point in pregnancy or breastfeeding. ACOG said it withdrew from the CDC's vaccine committee this year over "concerns about recent changes that undermine the committee's scientific integrity."

NO AMOUNT OF ALCOHOL IS PROTECTIVE. AND THE GUIDELINES FOR MEN AND WOMEN ARE CONVERGING.

A new analysis found alcohol's health risks start climbing at relatively low levels for both men and women, with almost identical thresholds for increased mortality risk. Researchers estimated that drinking more than about 6.5 drinks per week for men and 7 drinks per week for women pushed lifetime alcohol-related death risk above 1 in 1,000, while risks exceeded 1 in 100 at roughly 8.5 drinks per week for both sexes. The findings challenge the long-standing U.S. dietary guidelines that allow men up to two drinks per day but women only one. The authors argue future guidance should recommend no more than one drink daily for everyone.

WHAT NEW MOTHERS EXPECT OF THEIR SLEEP MAY SHAPE WHAT THEY GET

Among around 430 pregnant women, those who expected the worse sleep after delivery ended up actually having worse sleep, measured by both wrist trackers and self-report. And that is after researchers accounted for prior sleep problems and psychiatric history. Postpartum anxiety deepened the effect. Researchers say sleep beliefs and anxiety, unlike most postpartum risk factors, could be addressed during pregnancy, before the sleepless months arrive.

MENOPAUSE IS HITTING WOMEN RIGHT WHEN THEY'D REACH THE TOP

Menopause arrives around 52, and the average CEO is hired at 54. Fast Company reports that senior women said menopause is quietly pushing them out: lost confidence, a blazer thrown off mid-boardroom meeting, careers abandoned. Only 11% of companies offer menopause benefits, the same share of Fortune 500 CEOs who are women. Half of women say their workplace never discusses it at all.

AMERICANS ARE COOLING ON BIRTH CONTROL

The share of Americans who say birth control is morally acceptable fell to 83%, a record low since Gallup started asking in 2012. Last year, approval was 90%. Independents drove the slide, with their acceptance down 11 points in a single year. Birth control has ranked as the single most morally acceptable behavior Gallup tracks every year it's been on the list, which is what makes the dip worth watching.

THE FDA REOPENS MIFEPRISTONE'S SAFETY QUESTION

The FDA launched the safety review of mifepristone they had promised for months, a drug that accounts for about two-thirds of U.S. abortions. Former FDA Commissioner Marty Makary had allegedly said the study would be delayed because it would be unpopular to release before the midterm elections. The agency still says the drug is safe and effective when used as directed, and HHS insists it has been reviewing the drug's safety rules for months, disputing that anything new just began. Preliminary results are expected in July; the full review likely won't land until after the November midterms.

YOUR PHONE MAY FLAG PERIMENOPAUSE?

At its developer conference Monday, Apple said the Health app will start alerting women 40 and older when their logged cycle patterns suggest perimenopause, then steer them toward symptom tracking and educational material to bring to a doctor. It's the company's deepest move into women's health since it launched period tracking in 2019.

A BREAST-CANCER SIGNAL IN THE WEIGHT-LOSS DRUGS

A study found that around 110,000 women ages 45 to 80 carrying extra weight were 30% less likely to be diagnosed with breast cancer while taking GLP-1 drugs like Ozempic and Wegovy. The study was observational, so it can't prove the drugs deserve the credit, and the team is now standing up a clinical trial to test the link directly. Obesity after menopause is a known breast cancer risk factor, but researchers suspect the drugs' effects on weight *and* inflammation may be doing the work.

BEING FEMALE MAY NOT BE THE AFIB STROKE RISK WE THOUGHT

For years, simply being a woman has counted as a stroke risk factor in atrial fibrillation, the most common heart-rhythm disorder. That earned female patients an automatic point towards being put on blood thinners. A Tulane analysis of roughly 950,000 patients found that may be too blunt: under age 75, women and men faced essentially the same one-year stroke risk, with the added risk showing up mainly in women 75 and older. Because blood thinners carry real bleeding risks, the authors argue the call should be individualized and point to a newer scoring system that drops sex as a standalone factor.
