Men’s underwear and fertility risks go viral as doctors push back on claims
NEWYou can now listen to Fox News articles!
Men are swapping out their underwear over growing concerns about fertility and hormone health.
The movement has been happening online, as some men are attempting to swap out their polyester shorts and undergarments for cotton, wool and other organic materials.
They are avoiding synthetic fabrics over concerns about microplastics, “forever chemicals” and a potential link to infertility, according to a report by The Wall Street Journal.

Recent studies have suggested that microplastics — most often found in the environment, air, water and food — can carry pollutants into the human organs and cause health complications, such as cancer, inflammation, cardiovascular issues and cell damage.
As more organic underwear brands for men surface and grow in popularity, these concerns have also been fueled by conversations on social media and podcasts.

Dr. Paul Turek, a reproductive urologist and microsurgeon in California, told the Journal that “microplastic conversations are constant now.”
Although he advises his patients to reduce plastic exposure, Turek said he has yet to see research to validate these concerns.
THE HIDDEN REASON SCIENTISTS SAY BOTTLED WATER MAY NOT BE THE CLEANER CHOICE
Dr. Jaime Knopman, director of fertility preservation at CCRM Fertility New York and author of “Own Your Fertility,” told Fox News Digital that “theoretically,” wearing briefs can pose a fertility risk, but not just because of the material.
“While a change in underwear could help improve fertility, it is rarely the sole cause of infertility.”
“The tight fit can raise the temperature of a man’s testes, which could reduce sperm quality and quantity, causing a decline in fertility,” she said. “However, in my experience, I have not found a direct correlation between wearing briefs and a patient’s fertility.”
Knopman added that she hasn’t seen changes in patients who have switched underwear material or style.

In an interview with Fox News Digital, Dr. Alex Robles of Columbia University Fertility Center in New York echoed that there is “no strong evidence that specific fabrics alone have a meaningful impact on male fertility.”

“With that said, higher scrotal temperatures from any source (heat exposure, tight clothing, prolonged sitting or cycling) have been linked to reduced semen quality in some studies,” he said.
“Switching underwear alone rarely causes meaningful changes in fertility. However, some men may see small improvements in sperm quality if they move away from very tight styles that increase heat production and retention.”
Reducing risk
If a male patient has an abnormal semen analysis, Knopman said she always suggests making some lifestyle modifications to improve sperm health, including sleep, diet and exercise (in addition to seeing a urologist).

“Throwing a change of underwear into the mix couldn’t hurt, but it’s nearly impossible to determine if a semen analysis is irregular because of a man’s underwear choices,” she said. “Therefore, while a change in underwear could help improve fertility, it is rarely the sole cause of infertility.”

Knopman emphasized that fertility is “not just a female problem,” and that modifications in lifestyle choices should apply to both men and women.
“If a male patient tells me he is riding a bike for two hours a day or spending an hour in a hot bath, I am going to tell him to cut that out,” she said. “While it may not be the reason for his sperm troubles, modifying his lifestyle can’t hurt.”

“Just like I tell my female patients, you can’t blame yourself for your infertility,” she went on. “Most habits in life are totally fine as long as they are in moderation.”

Robles advised men to choose comfortable, non-restrictive underwear, avoid excessive heat exposure, increase food variety, and reduce exposure to toxins, including smoking and excessive alcohol.
“The biggest drivers of male fertility decline are age, obesity, smoking, heat exposure, environmental toxins and underlying medical conditions,” he said. “If you are struggling with a fertility issue, I recommend seeing a fertility specialist.”

Dementia risk signals could lie in simple blood pressure readings, researchers say
NEWYou can now listen to Fox News articles!
Simple measurements taken during routine blood pressure checks could predict dementia risk years before symptoms appear.
That’s according to new research presented this week at the American College of Cardiology’s Annual Scientific Session in Louisiana.
The findings draw on two studies led by researchers at Georgetown University, which suggest that monitoring how blood vessels age and stiffen over time can provide a window into future cognitive health.
LURKING DEMENTIA RISK EXPOSED BY BREAKTHROUGH TEST 25 YEARS BEFORE SYMPTOMS
Data shows rates of dementia and aging-related cognitive decline are expected to increase as populations age, and half of U.S. adults have high blood pressure (hypertension).
Scientists believe that efforts to better address hypertension, a key contributor to heart disease and a risk factor for dementia, could affect both cardiac and brain health.

“Blood pressure management isn’t just about preventing heart attacks and strokes; it may also be one of the most actionable strategies for preserving cognitive health,” Dr. Newton Nyirenda, the study’s lead author and an epidemiologist at Georgetown University in Washington, said in a press release.
The research focused on two metrics, the pulse pressure-heart rate index and estimated pulse wave velocity. Both were calculated using data collected during standard doctor visits, such as heart rate, age and blood pressure.
“Blood pressure management isn’t just about preventing heart attacks and strokes; it may also be one of the most actionable strategies for preserving cognitive health.”
Researchers examined five years of data patterns for more than 8,500 people in the SPRINT trial, a large study of adults 50 years and older with hypertension. In the follow-up, 323 of the participants developed probable dementia.
HIDDEN BRAIN CONDITION MAY QUADRUPLE DEMENTIA RISK IN OLDER ADULTS, STUDY SUGGESTS
In one study, the team found the pulse pressure-heart rate index was a strong independent predictor of dementia risk in adults over 50. For participants under 65, every one-unit increase was associated with a 76% higher risk of developing dementia.

The second study found that adults with consistently elevated or rapidly increasing pulse wave velocity were more likely to develop dementia than those with stable velocity, even after accounting for factors like smoking, gender and cardiovascular history.

“Our findings suggest that vascular aging patterns may provide meaningful insight into future dementia risk,” said Nyirenda. “This reinforces the idea that managing vascular health earlier in life may influence long-term brain health.”

The team emphasized that clinicians should tailor risk assessments and treatment strategies to the individual.
Further studies are needed to confirm these parameters and determine whether changing vascular aging trajectories reduces dementia risk. (iStock)
“You don’t want to wait until a patient starts manifesting cognitive decline before you act,” said senior study author Sula Mazimba, an associate professor at the University of Virginia.

Researchers noted the study could not establish causation. Other limitations included the fact that participants already had hypertension and elevated cardiovascular risk, meaning the findings may not apply to people without those conditions.

Further studies are needed to confirm these findings and to determine whether improving blood vessel health over time could reduce dementia risk.

‘Gas station heroin’ banned in another state amid nationwide crackdowns
NEWYou can now listen to Fox News articles!
A dangerous substance dubbed “gas station heroin” continues to alarm medical professionals, with more states making moves to restrict or ban tianeptine.
Fourteen states have officially classified the tricyclic antidepressant as a Schedule I controlled substance.
Connecticut is the latest state to crack down, officially banning the sale and use of the substance starting on Wednesday.
HEALTH OFFICIALS WARN OF DANGEROUS SUBSTANCE AVAILABLE IN STORES ACROSS THE NATION
Tianeptine, which can produce euphoria in higher doses, can be more potent than morphine and addictive opioids, according to the U.S. Food and Drug Administration.
Some countries have taken steps to restrict how tianeptine is prescribed or dispensed, and have even revised the labels to warn people of its potential addictive qualities.

Misuse of tianeptine can cause severe adverse health effects, including respiratory depression, severe sedation and death, according to the Drug Enforcement Administration.
Some companies market the drug as an aid for pain, anxiety and depression, or as a means of improving mental alertness in a pill, powder, salt or liquid form.
The products are typically sold at convenience stores, gas stations, vape shops and online retailers, and go by names like Tianaa, ZaZa, Neptune’s Fix, Pegasus and TD Red.

Connecticut Lt. Gov. Susan Bysiewicz said in a press release that the schedule change is a necessary step to combat addiction.
“With false marketing that led consumers to believe these are safe products, and with candy-like flavor options, these substances posed a clear threat to those battling substance-use disorder and our youngest residents,” she added.

The Nutmeg State also added Mitragyna speciosa (kratom), 7-hydroxymitragynine, Bromazolam, Flubromazolam, Nitazenes and Phenibut to the schedule classification.
Earlier this month, FDA Commissioner Martin Makary penned a letter sounding the alarm on what he called a “dangerous and growing health trend.”

“I am very concerned,” Makary wrote. “I want the public to be especially aware of this dangerous product and the serious and continuing risk it poses to America’s youth.”
New York-based Robert Schwaner, M.D., vice chair of system clinical affairs at Stony Brook Emergency Medicine, told Fox News Digital that the FDA has never approved tianeptine as a dietary supplement.
“As with heroin and other opioids, significant mu-opioid receptor stimulation ultimately results in a loss of respiratory drive and subsequent cardiac arrest.” (Dekalb County Sheriff’s Office)
“The euphoria at low doses is primarily due to increased serotonergic activity from its serotonin reuptake effects. With increasing doses, the mu-opioid receptor stimulation may become lethal,” said Schwaner. “As with heroin and other opioids, significant mu-opioid receptor stimulation ultimately results in a loss of respiratory drive and subsequent cardiac arrest.”
Schwaner said he believes the substance requires national regulation due to its addictive qualities.

“Acting at the same receptor as opioids, tianeptine has the potential for an individual to develop tolerance, subsequent dependence and withdrawal from its use,” he cautioned.
Fox News Digital reached out to the FDA for comment.
