When and Who can get a coronavirus vaccine?

Federal government officials are promising coronavirus vaccines soon - some even before Christmas - and states are gearing up to begin vaccinating Americans sometime in December. It almost sounds as if people will be lining up everywhere before New Year’s to get a vaccine. But while millions of health care workers may be able to get immunized against the virus before the end of the year, the rest of the population is going to have to wait for months.

Is a common shoulder surgery useless?

New research casts doubt on the true effectiveness of a common type of surgery used to ease shoulder pain. A British research team tracked outcomes for patients who underwent “decompression surgery” to treat shoulder impingement - a condition where a shoulder tendon rubs and catches in the joint. In decompression surgery, a small area of bone and soft tissue in the shoulder joint is removed, opening up the joint to prevent the abrasion that happens when the arm is lifted.

Preventing child obesity in the next generation must start before conception

The key to preventing obesity in future generations is to make their parents healthier before they conceive, leading health researchers suggest. In a series of papers, published in The Lancet Diabetes and Endocrinology, the researchers say that the time before couples conceive represents a missed opportunity to prevent the transmission of obesity risk from one generation to the next. They argue that a new approach is needed to motivate future parents to live a healthier lifestyle. There is now a wealth of evidence that the risk of obesity and its associated conditions, such as heart disease diabetes and some cancers, could impact the developing baby. In turn, when the child becomes a young adult they may pass the risk of obesity on to their children - it is a vicious cycle.

It’s time to consider propranolol as an anti-cancer drug, researchers say

Propranolol, a beta-blocker commonly prescribed to treat irregular heart rates and other conditions, has significant anti-cancer properties, say researchers in a new clinical study published in ecancermedicalscience. The Repurposing Drugs in Oncology (ReDO) project, an international collaboration between the Anticancer Fund, Belgium, and US based GlobalCures, says that existing and widely-used non-cancer drugs may represent a relatively untapped source of novel therapies for cancer. Historically, pharmaceutical companies devote little time to “repurposing” existing drugs. The ReDO project hopes to change that, raising awareness by publishing a series of articles in ecancer to share evidence for using these therapies in cancer medicine.

How long should children play video games?

A new study indicates that playing video games for a limited amount of time each week may provide benefits to children, but too much can be detrimental. The findings are published in the Annals of Neurology. There’s much debate over the potential benefits and risks of video gaming in children and teens. To provide some clarity, Jesus Pujol, MD, of the Hospital del Mar in Spain, and his colleaguesinvestigated the relationship between weekly video game use and certain cognitive abilities and conduct-related problems. In their study of 2442 children aged 7 to 11 years, the researchers found that playing video games for one hour per week was associated with better motor skills and higher school achievement scores, but no further benefits were observed in children playing more than two hours each week.

E-cigarette vapor does not cause oxidative stress in viable lung epithelial cells

E-cigarette vapour is much less harmful to lung cells than cigarette smoke. Lab tests show that, unlike tobacco smoke, which causes oxidative stress and cell death, e-cigarette vapour does not. Oxidative stress and cell death are driving factors in the development of many smoking-related diseases such as COPD and lung cancer. Vapour from e-cigarettes has been found to contain significantly lower levels of the toxicants found in cigarette smoke (Chemical Research in Toxicology DOI: 10.1021/acs.chemrestox.6b00188), but suitable lab tests and clinical studies are necessary to understand whether this translates into reductions in biological responses and disease. Researchers at British American Tobacco have developed a standardized way of measuring and comparing the potential of conventional cigarette smoke and e-cigarette vapour to cause oxidative stress in an in vitro model of lung epithelium.

Heavy hitters: Obesity rate soars among professional baseball players

Major League Baseball players have become overwhelmingly overweight and obese during the last quarter century, say health researchers. David E. Conroy, Penn State professor of kinesiology, and colleagues looked at 145 years of data on professional baseball players’ body mass. The researchers found that the athletes’ weight held steady for over 100 years, with the majority of them weighing in at what is considered “normal,” - i.e., with a body mass index (BMI) between 18.5 and 24.9. However, around 1991 the average player’s BMI began to rise, and over the last 25 years nearly 80 percent of players fall into the overweight or obese category with a BMI above 25. Obesity in the general U.S. population began to rise in the mid-1970s, according to the Centers for Disease Control and Prevention. “Research exists that shows how having extra weight can help with certain aspects of baseball,” said Conroy, also professor of human development and family studies. “The more force a batter can put into the ball, the further it will travel.”

Rap1, a potential new target to treat obesity

cientists at Baylor College of Medicine, the National Institutes of Health and Virginia Tech Carilion Research Institute have discovered a new mechanism in the mouse brain that regulates obesity. The study, which appears in Cell Reports today, shows that this new mechanism can potentially be targeted to treat obesity. “It’s well known that the brain is involved in the development of obesity, but how a high-fat diet changes the brain so it triggers the accumulation of body fat is still unclear,” said senior author Dr. Makoto Fukuda, assistant professor of pediatrics at Baylor and the USDA/ARS Children’s Nutrition Research Center at Baylor and Texas Children’s Hospital. Fukuda and colleagues studied the mouse Rap1 gene, which is expressed in a variety of tissues, including the brain where it is involved in functions such as memory and learning. Little was known, however, of the role brain Rap1 plays in energy balance.

Belief about nicotine content in cigarette may change brain activity and craving

How the brain responds to nicotine depends on a smoker’s belief about the nicotine content in a cigarette, according to new research from the Center for BrainHealth at The University of Texas at Dallas. The study, recently published in Frontiers in Psychiatry, found that smoking a nicotine cigarette but believing that it lacked nicotine failed to satisfy cravings related to nicotine addiction. Contrary to their expectations, researchers found that in order to satisfy nicotine cravings, smokers had to not only smoke a cigarette with nicotine but also believe that they were smoking nicotine. “These results suggest that for drugs to have an effect on a person, he or she needs to believe that the drug is present,” said Dr. Xiaosi Gu, assistant professor in the School of Behavioral and Brain Sciences and the study’s lead author.

You Can Stop Feeling Bad About Eating Chocolate

Whether you’re an avid baker, or just love a sweet treat, it’s hard to resist the appeal of chocolate. But increasing evidence shows that resistance may not be necessary. Studies demonstrate myriad benefits of chocolate, from creating a feel-good buzz to boosting cardiovascular health. Read on to learn more, then try some healthy recipes. The Latest Research A recent study in the journal Heart shows that habitual chocolate consumption is linked to a lower risk of cardiovascular disease and stroke. Keeping in mind that the study only demonstrated correlation (not causation), it’s nonetheless exciting to see that among participants who consumed a relatively high volume of chocolate every day, 12% developed or died of cardiovascular disease during the 12-year study. Compare that to participants who didn’t eat chocolate at all, among whom 17.4% developed or died of the disease. How much were the chocolate-eaters consuming? About 16 to 100 grams per day, or roughly one half to two typical chocolate bars.

Overweight and obese type 2 patients show improvements with structured nutrition therapy

Researchers at Joslin Diabetes Center have announced the results of a study that may change how nutrition therapy is delivered to overweight and obese patients with type 2 diabetes. The “Nutrition Pathway Study” compared three models of nutrition therapy and found that a highly structured nutrition plan provides the most significant impact on A1C, body weight and lipid profiles. The study results were presented at the American Diabetes Association’s 76th Scientific Sessions in New Orleans, Louisiana. Participants in the structured nutrition therapy arm of the study reduced A1C by an average of 0.67 percent and reduced body weight by an average of 3.5 Kg over 16 weeks. According to Osama Hamdy, M.D., Ph.D., Medical Director of the Obesity Clinical Program at Joslin Diabetes Center and lead investigator on the study, these results were achieved without increasing exercise, changing medications or undertaking behavioral changes. “This drop in A1C due to nutrition therapy alone is much better than what we have been able to achieve with many of the current medications for type 2 diabetes ,” said Dr. Hamdy. “This is very encouraging since participants in the study have lived with type 2 diabetes for more than 10 years and were not able to control their blood glucose or weight with multiple medications.”

Researchers explore epigenetic influences of chronic pain

Chronic pain is one of the most prevalent, disabling and expensive public health crises in the United States. It affects more than 100 million Americans, with annual costs estimated at $635 billion, says a 2014 report from the American Pain Society. Despite the enormous societal impact of chronic pain, present treatment options are limited to nonsteroidal anti-inflammatory drugs (NSAIDS), opioids, anticonvulsants and antidepressants, which provide pain relief to only about half of patients. Furthering the problem, prescription opioid overdoses have quadrupled since 1999. There were more than 45,000 painkiller-related deaths in 2014 alone, according to the Centers for Disease Control and Prevention. Now, researchers at Drexel University College of Medicine are aiming to identify new molecular mechanisms involved in pain. Their latest study, published this month in Epigenetics & Chromatin, shows how one protein - acting as a master controller - can regulate the expression of a large number of genes that modulate pain.

Global study shows diabetes and heart disease can be a deadly combination

The combination of type 2 diabetes and coronary artery disease can be deadly. New research from a global study led by a physician from UConn Health has found that patients with Type 2 diabetes admitted into the hospital for congestive heart failure face a one in four chance of dying over the next 18 months. The results were presented on June 11 at the American Diabetes Association’s (ADA) annual meeting in New Orleans and published online in the ADA journal Diabetes Care. The findings paint a much grimmer picture of the outcome for diabetes patients with severe heart disease than was previously known.

A family-based weight management program improved self-perception among obese children

Battling the childhood obesity epidemic is a priority for many researchers, as obesity during adolescence increases the risk of chronic diseases throughout life. Because obese children have lower quality of life and self-esteem, greater levels of depression and anxiety, and also face more teasing and bullying than normal-weight peers, including mental health in any intervention is necessary. To that end, researchers studied the self-perception of children participating in the Fit Families program. Fit Families is a program based on Social Cognitive Theory delivered through the New Mexico Cooperative Extension service. The program was developed for areas of southern New Mexico lacking resources to help combat childhood obesity in a positive, culturally appropriate manner by encouraging healthy food and nutrient intake and increased physical activity. For this study, children with a body mass index at least in the 85th percentile were referred by local physicians. The final study included 46 children, ranging from 8 to 17 years of age, 43% of whom were male, and 80% of whom were Hispanic. “With our emphasis on fun physical activity, children and parents reported enjoying the games at Fit Families. We believe this may have resulted in the children’s increased self-perception related to their athletic ability,” said Martha Archuleta, PhD, RD, lead author of the study. “Children also improved the perception of their physical appearance, possibly due to the way self-acceptance and diversity of body sizes were promoted.”

Changes needed to increase access to colorectal cancer screening

Colorectal cancer is the second highest cause of cancer death in the United States, expected to claim the lives of an estimated 49,190 people in 2016. The Affordable Care Act (ACA) aimed to increase access to CRC screening by not holding patients responsible for all costs of the procedure, yet current Medicare insurance beneficiaries lacking supplemental insurance may not be able to afford colon cancer screening and treatment. This policy disproportionally puts low-income Americans at risk and adds unnecessary strains on overall health care costs, according to a commentary in the May issue of the journal Gastroenterology. “Study after study shows that screening saves lives,” said Chyke A. Doubeni, MD, MPH, chair and the Presidential Associate Professor of Family Medicine and Community Health at the Perelman School of Medicine at the University of Pennsylvania, and lead author of the commentary. “Yet many of those in the group most affected by this deadly disease are unable to afford the screening they critically need. We must renew efforts to ensure equitable access to and use of disease prevention, detection, and treatment services for colorectal cancer.” For CRC screening, a full colonoscopy is necessary, where the doctor inspects the rectum and entire colon through a flexible lighted tube, and can remove any abnormal growth. The entire colon has to be cleansed before the colonoscopy, for which the patient is usually sedated There are currently an estimated 55.5 million Medicare beneficiaries in the U.S. A 2010 Kaiser Family Foundation survey found that 14 percent lacked supplemental coverage. Until recently, colon cancer screening has been viewed as a one-time activity, while in practice, screening is a series of clinical activities to identify and test patients and perform diagnostic confirmation when necessary. This series of tests and steps include a diagnostic workup, which can include a biopsy to obtain a tissue sample or polypectomy, in which polyps are removed to prevent them from becoming cancerous.

Why do certain hormonal contraceptives increase the risk of HIV?

In recent years, evidence has been building that injectable contraceptive depot medroxyprogesterone acetate (Depo-Provera or DMPA) is associated with an increased risk of HIV infection. Now a study published in the September 1st issue of mBio, an online open-access journal of the American Society for Microbiology, provides a biological explanation for the phenomenon. The findings will help women make more informed choices about birth control. “Before this study, there were all these controversial reports, some showing that DMPA increases the risk of HIV infection and others showing it doesn’t, and there was no biologic explanation for the differences between studies,” said lead author Raina Fichorova, PhD, MD, director of the Division of Genital Tract Biology at Brigham and Women’s Hospital and associate professor of obstetrics and gynecology and reproductive biology at Harvard Medical School, Boston. “This new study offers an explanation for the inconsistent studies, and it lies in the microbial communities of the reproductive tract.” The researchers analyzed cervical swabs and data from 823 women, between the ages of 18 and 35, who were HIV negative and enrolled in family planning clinics in Uganda and Zimbabwe. Roughly 200 women in this cohort became HIV infected. Women were divided into three groups, those who used DMPA, those who used estrogen-progesterone oral contraceptives, and those who used no hormonal contraceptives. Within each of these groups, the investigators compared results for women with a healthy vaginal environment (dominated by Lactobacillus-morphotypes and free of bacterial vaginosis) to women who had a disturbed vaginal microbioata or an infection from bacteria, fungi or parasites.

Stronger working memory and reduced sexual risk-taking in adolescents

Teenagers vary substantially in their ability to control impulses and regulate their behavior. Adolescents who have difficulty with impulse control may be more prone to risky sexual behavior, with serious consequences such as sexually transmitted diseases and unintended pregnancies. A new study has found that individual differences in working memory can predict both early sexual activity and unprotected sexual involvement during adolescence. Working memory - the system in the brain that allows individuals to draw on and use information to plan and make decisions - develops through childhood and adolescence. The new study found that adolescents with weaker working memory have more difficulty controlling their impulsive urges and considering the consequences of their behaviors. The study was carried out by researchers at the University of Oregon, the University of Pennsylvania, and the Children’s Hospital of Philadelphia. It appears in the journal Child Development. Prior research in this field has linked impulsivity and lack of self-control to risky behaviors during adolescence. This study builds on earlier findings, focusing instead on cognitive abilities, such as the ability to concentrate on tasks and filter out distractions, which rely on working memory.

Lower heart rate variability turns women off

Chances are good that women with a low heart rate variability also suffer from sexual dysfunction. That’s the finding from a study led by Amelia Stanton of The University of Texas at Austin in the US published in Springer’s journal Applied Psychophysiology and Biofeedback. Heart rate variability refers to differences in the length of time between consecutive heartbeats. It is one of the most sensitive and objective measures of the interplay between the sympathetic nervous system (which activates the so-called fight or flight response) and the parasympathetic nervous system (which regulates the body’s unconscious actions such as heart beat and breathing). Together, these form the autonomic nervous system. If this is in balance and functioning properly, a person will be able to adapt to physiological or environmental changes and stresses when needed. Heart rate variability, in particular, plays a role in female sexual arousal function. It is a marker of a healthy heart and the body’s ability to modulate blood pressure appropriately within various contexts. This is important because sexual arousal is largely a matter of the selective manipulation of blood pressure in the genitals. Heart rate variability also relates to the processing of emotional cues. In this context, low resting heart rate variability may reflect poor emotional health and vice versa.

Many older adults going online to discuss, learn about sex

Forget those ageist stereotypes that senior citizens have little interest in sex and are befuddled by technology. Many older adults are going online to dish about the joys of sex and swap advice about keeping their mojos working well into their twilight years, a new study found. “Many older people preserve both a high interest in sex and a high involvement in sexual activities,” said researcher Liza Berdychevsky, a professor of recreation, sport and tourism at the University of Illinois who researches sexual behavior and well-being. “The popularity of sex-related discussions in seniors’ online communities suggests that, in a reality of limited alternatives for open and direct sex-related communication, seniors are finding channels to satisfy their needs for information and support.” Berdychevsky and co-author Galit Nimrod, a faculty member at Ben-Gurion University of the Negev, Israel, conducted an online ethnographic study - or netnography - in which they examined discussions of sexual topics in 14 online communities geared toward adults age 50 and older. Seven of the websites were based in the U.S., four in the U.K., two in Canada and one in Australia.

The first fraction of ejaculate is the most effective for conception

Sperm in the first fraction of ejaculate are more numerous, move more and present better quality DNA than those lagging behind. This is the conclusion of a study led by the Ginemed fertility clinic, which confirms that while the objective of the first fraction is to fertilise the egg, the second phase is so that no sperm from any other male has a chance to fertilise it. A study led by the Ginemed Assisted Human Reproduction Clinic analyses the advantages of using fractions of ejaculate separately in in-vitro fertilisation as a way to improve the sample of the semen. The researchers’ hypothesis was that, comparing the different fractions of semen in an ejaculation, the first would contain sperm with better seminal parameters and could be used as an effective method for selecting sperm prior to fertilisation.

Caffeine intake associated with reduced levels of erectile dysfunction

Men who drink the equivalent caffeine level of two to three cups of coffee a day are less likely to have erectile dysfunction (ED), according to researchers from The University of Texas Health Science Center at Houston (UTHealth). The results of a study published recently in PLOS ONE found that men who consumed between 85 and 170 milligrams of caffeine a day were 42 percent less likely to report ED, while those who drank between 171 and 303 milligrams of caffeine a day were 39 percent less likely to report ED compared to those who drank zero to seven milligrams a day. This trend was also true among overweight, obese and hypertensive men. “Even though we saw a reduction in the prevalence of ED with men who were obese, overweight and hypertensive, that was not true of men with diabetes. Diabetes is one of the strongest risk factors for ED, so this was not surprising,” said David S. Lopez, Dr.P.H., M.P.H., lead author and assistant professor at UTHealth School of Public Health.

Changing attitudes about sex

Acceptance of premarital sex is at an all-time high along with an acceptance of homosexuality, find researchers led by Jean M. Twenge from San Diego State University. The researchers - also including Ryne Sherman from Florida Atlantic University and Brooke E. Wells from Hunter College - analyzed data from the General Social Survey, a nationally representative survey of more than 33,000 U.S. adults taken between 1972 and 2012. They found substantial generational shifts in attitudes toward non-marital sex and number of sexual partners. The results were published today in the Archives of Sexual Behavior. “The changes are primarily due to generation - suggesting people develop their sexual attitudes while young, rather than everyone of all ages changing at the same time,” said Twenge, who is also the author of “Generation Me.” “This has caused a large generation gap in both attitudes toward premarital sex and number of sexual partners,” she said.

New study reveals mixed picture on the effectiveness of Viagra and related drugs

Viagra and other related drugs are not a universal ‘cure-all’ for impotence, according to a new study from The University of Manchester and NatCen Social Research. Drugs, clinically known as oral phosphodiesterase type 5 inhibitors (PDE5i), have become the first-line medical treatment option for sufferers of erectile dysfunction (ED) - also known as impotence - since entering the UK market in 1998. An abundance of studies has demonstrated the effectiveness of such drugs. But researchers at The University of Manchester, who have studied the responses of more than 2,600 English men (aged 50-87 years), suggest that restoring ED pharmacologically is not a ‘cure-all’. Lead author of the study, Dr David Lee, found that older sufferers of ED who had used Viagra, or similar drugs such as Cialis and Levitra, still expressed concern or dissatisfaction with their sex lives.

Breastfeeding women and sex: Higher sex drive or relationship management?

New mothers in the Philippines spend more time in the bedroom with their partner in the first few weeks after giving birth than they did before they became pregnant. This might be a type of survival strategy to keep the relationships with the fathers of their new babies alive and well, to ensure continued support for their offspring. So says Michelle Escasa-Dorne of the University of Colorado in the US, after studying how women from a society with a low divorce rate such as the Philippines adapt to being both mothers and lovers. The study appears in Springer’s journal Human Nature. A range of studies previously conducted on how women in Western societies experience the first six weeks after giving birth show that they tend to devote more time to their offspring’s well-being than to their partner. This leads to lower relationship satisfaction and less intercourse between partners, and a clear shift from so-called mating efforts to parenting efforts. Escasa-Dorne set out to understand if similar trends are also found among women in a non-Western population with a low divorce rate. She questioned 260 women who were in a relationship and living in the Philippines’ capital of Manila. Of these, 155 women still breastfed. They completed questionnaires about their sexual functioning and menstrual cycles, as well as about how satisfied and committed they were in their current relationships. The women were between 18 and 35 years old, mostly married, well-educated, and had on average two or three children. Breastfeeding women who had already resumed having their periods were more sexually active and committed than others.

Statins and Your Sex Life

The science on statins and sexual function is inconclusive, but it does appear that taking a statin may sometimes affect a person’s sex life. On the plus side, some men report improved erections when their high cholesterol was treated with statins, said Dr. Steven Nissen, chairman of the department of cardiology at the Cleveland Clinic. It is plausible that lowering cholesterol improves the function of the cells that line blood vessels, which could help erectile function, he said. But a 2008 report from the University of California, San Diego, tells a different story. Researchers looked at statin use and sexual function in 1,000 men and women, half of whom were given a statin and half of whom took a placebo. Over all, men on statins were about twice as likely as those taking placebos to report that their ability to achieve orgasm had become “somewhat worse” or “much worse.” Dr. Beatrice Golomb, a professor at the University of California, San Diego, medical school, who helped conduct that study, says doctors don’t always take patients seriously when they talk about side effects, sexual or otherwise. In other research, Dr. Golomb found that when patients complained about the most commonly recognized side effects of statins, their doctors denied the possibility of a connection more than half the time.

Sexual dysfunction inadequately reported in hair loss drug trials

Published reports of clinical trials provide insufficient information to adequately establish the safety of finasteride for treatment of hair loss in men, according to a new Northwestern Medicine study to be published April 1 in JAMA Dermatology. This study is the first meta-analysis of the quality of safety reporting in clinical trials of finasteride for treatment of male hair loss. Finasteride blocks 5α-reductase in the scalp and male reproductive organs, inhibiting the conversion of the male hormone testosterone to its more potent form, 5α-dihydrotestosterone (5α- DHT). Men who take finasteride experience a 70 percent reduction in the amount of 5α-DHT in their blood. Not one of the 34 published clinical trial reports provided adequate information about the severity, frequency or reversibility of sexual adverse effects. (Adequate quality of adverse event reporting requires using an explicit toxicity scale to grade adverse event severity and reported numbers and/or rates of occurrence for each specific type of adverse event per study arm.)

What effect does music TV have on the sexual behavior of teenage boys and girls?

There is no doubt that teenage boys and girls are swayed and shaped by music TV. For example, sexually active youth of both genders, after watching music TV, think their peers are sexually active, too. Moreover, when girls and boys perceive males in music videos as being sexually active, it makes boys watch more music TV, and girls watch less. These are some of the surprising findings from a study conducted at the Catholic University of Leuven in Belgium, published in Springer’s journal Sex Roles. The results question the frequently reported blanket influence of the mass media on teenagers’ sexual behavior. Watching music videos is a popular pastime of European and American teenagers. It does however receive its fair share of criticism for having too much sexual content, for objectifying women and for promoting a recreational view of sexual activities involving active men. It has been linked to teenagers’ becoming sexually active earlier in life. Over the course of one year, the researchers gathered information three times from 515 Belgian teenagers between the ages of 12 and 15 years old. They were asked how much music television they watched, how sexually active they were and indeed also how sexually active they thought their peers were. The researchers found that watching sexual music videos only had an effect on the sexual behavior of teenage boys, but not so on girls. The believe such behavior is influenced by the sexual scripts of music videos, which tend to show men taking the more active role in any sexual interaction.

Physical labor, hypertension and multiple meds may reduce male fertility

Working in a physically demanding job, having high blood pressure, and taking multiple medications are among health risks that may undermine a man’s fertility, according to a study by researchers at the National Institutes of Health and Stanford University, Stanford, California. The study is the first to examine the relationships between workplace exertion, health, and semen quality as men are trying to conceive. The results were published online in Fertility and Sterility. “Nearly 15 percent of U.S. couples do not become pregnant in their first year of trying,” said Germaine Buck Louis, Ph.D., the study’s senior author and director of the Division of Intramural Population Health Research at NIH’s Eunice Kennedy Shriver National Institute of Child Health and Human Development. “Male infertility plays a significant role, and our aim is to explore the influence of environmental factors and health status on semen quality.” Semen quality is a measure of a man’s ability to achieve fertilization and is based on the number, shape, and movement ability of sperm, as well as other factors. The investigators followed more than 500 couples in Texas and Michigan over a yearlong period. The couples were in committed relationships and stopped using contraception. All male participants completed preliminary interviews in which they were asked about their reproductive history, health, lifestyle and occupational activity. Most of the men provided a semen sample for analysis.
