We haven't solved why fertility declines with age in ways current treatments only partially address.
open
Global / Unspecified, Global
Fertility treatments like IVF help many people conceive, but success rates still drop significantly with age due to biological factors that current medicine can't fully reverse. Understanding and addressing this decline remains incomplete.

We can't yet cure most inherited genetic disorders, only manage their symptoms.
open
Global / Unspecified, Global
Conditions caused by a single faulty gene, from cystic fibrosis to muscular dystrophy, still mostly rely on symptom management rather than correcting the genetic cause itself. Gene therapy shows promise but remains far from a widely available cure.

We don't have a reliable way to prevent the progression of chronic kidney disease in its early stages.
open
Global / Unspecified, Global
Kidney disease often advances silently for years before symptoms appear, and by the time it's caught, treatment options are limited mainly to slowing further decline. Catching and reversing it earlier remains an open medical challenge.

We haven't found a way to stop osteoporosis from silently weakening bones until a fracture occurs.
open
Global / Unspecified, Global
Bone density loss often goes unnoticed until a fall causes a serious fracture, by which point significant damage has already occurred. Better early detection and prevention could avoid many of these life-altering injuries.

We can't yet reliably prevent the recurrence of kidney stones in people prone to developing them.
open
Global / Unspecified, Global
Kidney stones are painful and prone to recurring, yet prevention methods remain limited mostly to general dietary advice rather than addressing individual underlying causes. More targeted prevention could spare patients repeated painful episodes.

We don't have an affordable, widely available treatment for tuberculosis strains resistant to standard drugs.
open
Global / Unspecified, Global
Drug-resistant tuberculosis requires longer, more expensive, and more toxic treatment regimens that many patients in affected regions simply can't access or complete. This keeps a preventable disease deadly in the parts of the world least equipped to fight it.
Citation ID: WS00481
Title: We don't have an affordable, widely available treatment for tuberculosis strains resistant to standard drugs.

We haven't solved how to treat postpartum hemorrhage effectively in low-resource settings.
open
Global / Unspecified, Global
Severe bleeding after childbirth remains one of the leading causes of maternal death worldwide, disproportionately in regions lacking access to blood transfusions and advanced medical care. Affordable, effective solutions for these settings remain limited.

We can't yet fully explain why chronic pain sometimes persists long after an injury has physically healed.
open
Global / Unspecified, Global
Patients sometimes continue to experience pain months or years after the original injury has healed, suggesting the nervous system itself has changed in ways doctors don't fully understand. Solving this could transform treatment for chronic pain conditions.

Title: We can't yet fully explain why chronic pain sometimes persists long after an injury has physically healed.

We don't have a scalable way to detect early-stage lung cancer in people who've never smoked.
open
Global / Unspecified, Global
Lung cancer screening guidelines are generally built around smoking history, but a meaningful share of cases occur in people who never smoked at all and often go undetected until later stages. Better screening approaches for this group remain underdeveloped.

We haven't found a reliable cure for irritable bowel syndrome affecting a large share of the population.
open
Global / Unspecified, Global
IBS causes chronic digestive discomfort for a significant portion of people worldwide, yet treatment options remain limited to symptom management rather than addressing root causes. The underlying biology is still not fully mapped out.

We can't yet accurately predict which pregnancies will develop dangerous complications like preeclampsia.
open
Global / Unspecified, Global
Preeclampsia can develop suddenly and seriously endanger both mother and baby, and current screening still misses many cases until symptoms are already severe. Earlier, more accurate prediction could prevent serious harm.

We don't have a fully effective way to prevent hospital-acquired infections.
open
Global / Unspecified, Global
Despite strict hygiene protocols, patients still frequently contract infections during hospital stays that they didn't have when they arrived. Closing this gap could save both lives and enormous healthcare costs.

We haven't solved why chronic migraines affect some people far more severely than others.
open
Global / Unspecified, Global
Millions of people experience debilitating, unpredictable migraines that current treatments only partially control, and the underlying biological triggers remain incompletely understood. More precise treatment based on individual causes remains out of reach.

We can't reliably regenerate damaged cartilage in joints without surgery.
open
Global / Unspecified, Global
Cartilage has very limited ability to heal itself, which is why joint damage from injury or arthritis often leads to chronic pain or eventual joint replacement. Better regeneration methods could delay or eliminate the need for many of these surgeries.

We don't have an effective way to prevent hearing loss caused by long-term noise exposure.
open
Global / Unspecified, Global
Once noise-induced hearing damage occurs, it's typically permanent, and prevention still relies mainly on avoiding loud environments rather than any biological protection. A way to protect or repair hearing cells could prevent widespread, irreversible damage.
Citation ID: WS00472
Title: We don't have an effective way to prevent hearing loss caused by long-term noise exposure.

We haven't found a cure for tinnitus that works for most people who experience it.
open
Global / Unspecified, Global
The constant ringing or buzzing sound of tinnitus affects millions of people, and current treatments mostly help patients cope rather than eliminate the underlying cause. A real cure remains undiscovered.

We can't yet reliably treat postpartum depression before it causes lasting harm.
open
Global / Unspecified, Global
Many new parents experience postpartum depression that goes undiagnosed or untreated for months, affecting both their wellbeing and their infant's early development. Faster detection and more accessible treatment remain unmet needs.

We don't have a reliable way to prevent miscarriages in most cases where the cause is unknown.
open
Global / Unspecified, Global
A large share of pregnancy loss has no clearly identifiable cause, leaving expecting parents without answers or ways to prevent it happening again. Understanding these unexplained cases remains a significant gap in reproductive medicine.

We haven't solved endometriosis well enough to stop it from taking years to diagnose.
open
Global / Unspecified, Global
Many patients with endometriosis experience years of unexplained pain before receiving an accurate diagnosis, largely because it's difficult to detect without invasive procedures. Better, faster diagnostic tools remain a major unmet need.

We can't yet grow functional replacement skin fast enough for patients with severe burns.
open
Global / Unspecified, Global
Severe burn victims often face long, painful recoveries and permanent scarring because lab-grown skin grafts aren't yet fast or effective enough to fully replace damaged tissue. Faster, better regeneration methods could change burn treatment entirely.
