Researchers in the United Kingdom have made some surprising findings when it comes to lifestyle changes that have long been believed to help improve male fertility. Smoking, drinking, and body weight were found in a recent study to have no impact on fertility–and in fact, if couples delay treatment while waiting for the male partner to improve on these measures, their chances of achieving a pregnancy might actually decline because time continues to go by. Time.com reports:
Based on the data, researchers further found that lifestyle factors like use of recreational drugs, smoking, drinking and body weight had little effect. For instance, the proportion of men with low swimming sperm counts was similar whether they smoked over 20 cigarettes a day or if they had never smoked before. Alcohol use was also unrelated to fertility among men.
“The message of ‘No smoking, drinking in moderation, no street drugs and not be too overweight’ is clearly sound and should be offered to men as good health advice,” says study author Dr. Andrew Povey of University of Manchester’s School of Community Based Medicine. ”However, the evidence from this study is that even if the man changes his lifestyle in such a fashion, such changes are unlikely to improve his chances of conceiving a child.”
The findings came as a surprise to the researchers. “I expected to find a link with smoking, as studies have often reported that smoking is bad for semen quality,” says Povey. “When I looked again at the evidence for such statements, I found that it wasn’t necessarily that strong and that if there was an effect of smoking, it was more likely to occur within the normal range of semen quality and not then directly affect whether a man was likely to be infertile or not.”

A new survey conducted by the Centers for Disease Control and Prevention has found that more American teenagers smoke marijuana than cigarettes.
Twenty-three percent of the high school students who were surveyed about a number of risky behaviors said they recently smoked marijuana, while 18 percent said they had smoked nicotine cigarettes. According to MSNBC.com, some experts attribute the difference to the perception that marijuana is less dangerous than niccotine.

One in five high school students smokes, and 9 out of 10 current smokers started the habit before age 18, a new report from the U.S. surgeon general’s office has found. The report has led Surgeon General Dr. Regina Benjamin to declare that youth smoking has reached epidemic proportions.
The report criticizes the tobacco industry for spending an estimated $27 million each day marketing to teens, and calls for greater measures to prevent teens from starting a dangerous habit that will likely last their whole lives.
MSNBC.com has more:
“Today, more than 600,000 middle school students and 3 million high school students smoke. We don’t want our children to start something now that they won’t be able to change later in life,” Surgeon General Dr. Regina Benjamin said in the report, which details the scope, health consequences and influences that lead to youth tobacco use.
An estimated 3,800 kids pick up their first cigarette every day and 9 in 10 current smokers started before the age of 18. Some 99 percent of all first-time tobacco use happens by the age of 26, exposing young people to the long-term health effects of smoking, such as lung cancer and heart disease.
Smoking kills more than 1,200 people every day, and every tobacco-related death is replaced by two new smokers under the age of 25, the report said.

More than 100 playgrounds across the city of Boston are about to receive signs prohibiting smoking on the grounds. The signs read, “Children at Play, No Smoking,” and they are intended, The Boston Globe reports, to protect children from the harmful effects of second hand smoke, including asthma attacks, respiratory infections, lung cancer, and heart disease.
The signs are not legally binding; there are no new laws or city ordinances that prohibit smoking at playgrounds. But Boston’s mayor says the signs will empower parents to keep smokers at a distance from play areas.
“I know that nothing we put on the law books could be as strong as a parent who is trying to protect their kids from secondhand smoke and cigarette debris,’’ Mayor Thomas M. Menino said.
Similar initiatives are under way in 570 countries nationwide, the Globe reported.
Boston’s Public Health Commission cited studies suggesting that sitting outdoors a mere 3 feet from a smoker can expose a child to the same amount of second-hand smoke as sitting indoors in the same room with someone who is smoking. Other studies reported incidents of children being burned because lit cigarettes are held at a child’s eye level while they are running around a playground.

Researchers at the Centers for Disease Control and Prevention have found that more than 65 percent of American teenagers do not get enough sleep each night (“enough” sleep is defined as 8 hours or more). In a new study published online in the journal Preventative Medicine, the chronic lack of sleep is linked with a list of behaviors that are risky to teens’ health. Specifically, teens who didn’t get enough sleep:
- Drank soda or pop 1 or more times per day (not including diet soda or diet pop)
- Did not participate in 60 minutes of physical activity on 5 or more of the past 7 days
- Used computers 3 or more hours each day
- Had been in a physical fight 1 or more times
- Practiced current cigarette use
- Practiced current alcohol use
- Practiced current marijuana use
- Practiced currently sexually active
- Felt sad or hopeless
- Seriously considered attempting suicide
“Public health intervention is greatly needed, and the consideration of delayed school start times may hold promise as one effective step in a comprehensive approach to address this problem,” said Lela McKnight-Eily of the CDC’s Division of Adult and Community Health in a statement.
