Making Unique Observations in a Very Cluttered World

Poor semen quality in young men may predict future health issues, study says - 

Men with abnormal sperm are much more likely to die young than those with normal semen, research shows

Young men with fertility issues may face other health problems later in life, research published Wednesday in the journal Fertility and Sterility suggests.

Vascular, heart and skin disease, as well as hypertension, are among the ailments linked to poor semen quality in the Stanford University study, which analyzed nearly 9,400 men, ages 30 to 50, who visited a fertility clinic.

“This could be a great opportunity for young men to get a window into their future health,” study author Barry Behr, professor of OBGYN at Stanford University, and lab director of Stanford Medicine Fertility and Reproductive Health, told FoxNews.com. “Sperm cells move and are large, and we can quantify them. If this pans out to be true— which we believe it will— your sperm condition is a great surrogate marker for your overall health.”

Previous research suggests that obesity, smoking and cancer can impact fertility. In this study, scientists wanted to explore whether other conditions were linked with trends in sperm production.

Among the study participants, with a median age of 38, 44 percent attended the fertility clinic between 1994 and 2011 for a health problem unrelated to fertility.

After studying these men’s medical records, researchers observed that hypertensive disease, peripheral vascular, cerebrovascular disease and nonischemic heart disease displayed higher rates of semen abnormalities. For example, 56 percent of men without hypertensive disease had normal semen quality, but only 45 percent of men with hypertension had normal semen quality.

Poor semen quality was also linked to higher rates of skin disease— the association that Behr found most surprising. Despite the significance of hypertension and cardiovascular disease, those findings made sense, he said, because poor blood flow has been shown to influence sperm production.

“We’ve all seen this along the side of the road: When you see a line of trees, and maybe the tree at the end of the irrigation system isn’t nourished or fed with water as much as the rest will show lower viability. If you have increased pressure due to hypertension or vascular constriction, or issues with getting appropriate blood supply to the testicles, it’s analogous to not allowing the tree or the cells to get their full supply of nutrients to flourish.”

The study authors noted that although a link between semen quality and other health issues exists, knowing definitively whether semen quality is influencing the conditions— or whether the medications or conditions themselves are impairing sperm production— is unclear.

“Infertile men have lower testosterone levels than fertile men,” study author Michael Eisenberg, director of male reproductive medicine and surgery at Stanford University, told FoxNews.com. “Testosterone is important— it’s a biomarker for health. Maybe these men are on a different trajectory because of this impaired testicular function.”

Eisenberg noted that 10 to 15 percent of the DNA in a man’s body is devoted to reproduction, and most of these genes also have diverse functions in other bodily systems.

In their paper, researchers write that future studies may examine how treatments for hypertension and heart disease can be changed to improve male fertility. Analyzing whether treatments for cardiovascular disease themselves may impair semen production may also be beneficial. Cancer treatments such as radiation and chemotherapy can impact sperm production, Eisenberg noted.

However, the researchers’ findings still suggest that men who experience fertility issues may see their future health benefit by making dietary or fitness changes.

“I think that for a man who feels or seems otherwise healthy and has aberrant semen parameters,” Behr said, “it may provide additional motivation for the individual to drill more into their health assessment to make sure they don’t harbor a condition later in life that they may be able to change their lifestyle for.”

'Driving While Black' smartphone app alerts users of Racist Cops... -

'Driving While Black' smartphone app alerts users of Racist Cops... - 

Though the developers of the soon-to-be released "Driving While Black" smartphone application want motorists to download their product, there is a time when they definitely don't want users searching for it.
"Do not reach for your phone when you are talking to police," stressed Melvin Oden-Orr, one of two Portland lawyers creating the app.
Avoiding moves that could make police think you're reaching for a gun is just one tip included in the app that educates drivers about how to safely deal with police during traffic stops.
Despite its attention-grabbing name, Oden-Orr said the app due for release in late December will provide common sense advice to motorists of all races and outline what civil rights you have during a stop. With the phone hopefully in a hands-free device, the app allows drivers to send an alert to friends and family that they have been pulled over. There's also a recording function to document the interaction with an officer.
The app is coming to market as protesters around the country keep attention on instances of deadly encounters with police in Ferguson, Missouri, and New York City. Similar apps also are aimed at helping people navigate interactions with police.
Three Georgia teenagers created "Five-O," an app released this summer that lets people rate their interactions with law enforcement. And last month, American Civil Liberties Union affiliates in four states unveiled "Mobile Justice," an app that allows users to take video of police encounters and upload the video to the ACLU. It's modeled on "Stop and Frisk Watch," an app released for New Yorkers in 2012.
"It's obviously in the forefront of everybody's mind; the police know they are being recorded and people in public know they can record," said Sarah Rossi, director of advocacy and policy for the ACLU Missouri affiliate. "I think the benefit of this app (Mobile Justice) specifically is it goes straight to the ACLU and we can review it for any due-process violations."
The apps also include a "Know Your Rights" section that informs people about their rights when contacted by police.
Portland attorney Mariann Hyland got the idea for "Driving While Black" after learning of an app for drivers suspected of drunken driving. She approached Oden-Orr in April, and the two have been working on the app since summer with software developer James Pritchett.
The term "driving while black," perhaps unfamiliar to some, is common among African-Americans. A Justice Department report released last year, based on a survey of those stopped by police in 2011, suggests blacks are more likely than whites to be pulled over and have their cars searched. Moreover, African-Americans are much more likely to believe a traffic stop is not legitimate.
The issue has been on Hyland's radar since motorist Rodney King was beaten by Los Angeles police in 1991. Another key event hit closer to home. In 2003, a 21-year-old black woman was fatally shot by Portland police after she jumped from the backseat to the driver's seat during a traffic stop and tried to drive away.
Oden-Orr hosted a forum after the death, and Hyland attended. Afterward, Hyland promised she would do something to educate black youth on handling traffic stops. For years, she didn't keep that promise, and it bothered her.
The app is her attempt at rectifying the situation. Hyland and Oden-Orr say the key to surviving a traffic stop is to remain calm, keep your hands on the wheel, be respectful and make no false moves.
It doesn't sound difficult, but such encounters can be dangerous for police — putting them on heightened alert — and a driver might find it difficult to relax when convinced the stop is based on skin color.
"They describe a pattern of getting pulled over by the police, and they find it to be very frustrating and sometimes that frustration can lead to anger," Hyland said. "You have to always be mindful to check the anger."
The app will include a directory of lawyers for drivers who believe they were wrongfully stopped or searched. The app itself won't provide legal advice, such as telling users how to beat a traffic ticket.
"It's about being safe during a traffic stop so that everyone goes home alive," Oden-Orr said.
