BOSTON, March 14 (UPI) -- A diet high in fat was linked to a lower total sperm count and concentration among men, making it harder for them to have children, U.S. researchers said.

Jill Attaman, who was at Massachusetts General Hospital and an instructor at Harvard Medical School at the time of the research, said the study of 99 men found men who ate more omega-3 polyunsaturated fats -- found in fish and plant oils -- had better formed sperm than men who ate less.

The researchers questioned the men about their diet and analyzed samples of their semen from December 2006 to August 2010, measuring fatty acids in sperm and seminal plasma in one-quarter of the men.

The study participants were divided into three groups according to the amount of fats they consumed. The study, published in the journal Human Reproduction, found the one-third with the highest fat intake had a 43 percent lower total sperm count and 38 percent lower sperm concentration than men in the third with the lowest fat intake.

However, researchers warned this was a small study and the findings need to be replicated by further research.

"In the meantime, if men make changes to their diets so as to reduce the amount of saturated fat they eat and increase their omega-3 intake, then this may not only improve their general health, but could improve their reproductive health too," Attaman said in a statement. "At a global level, adopting these lifestyle modifications may improve general health, as high saturated fat diets are known to be a risk factor for a range of cardiovascular diseases; but, in addition, our research suggests that it could be beneficial for reproductive health worldwide."

High-fat diet may reduce sperm count

A diet high in saturated fat has been linked with a reduced sperm count.

A study of 99 men attending a US fertility clinic found those eating junk food diets had poorer sperm quality.

High intakes of omega-3 fatty acids, found in fish and plant oils, were associated with higher sperm concentration.

More work is needed to confirm the findings, the researchers report in the journal Human Reproduction.

The team, led by Prof Jill Attaman from Harvard Medical School in Boston, questioned men about their diet and analysed sperm samples over the course of four years.

Compared with those eating the least fat, men with the highest fat intake had a 43% lower sperm count and 38% lower sperm concentration (number of sperm per unit volume of semen).

..it does add weight to the argument that having a good healthy diet may benefit male fertility as well as being good general health advice.

Men consuming the most omega-3 fatty acids had sperm with a more normal structure than men with the lowest intake.

Prof Attaman said: "The magnitude of the association is quite dramatic and provides further support for the health efforts to limit consumption of saturated fat given their relation with other health outcomes such as cardiovascular disease."

Toothbrush? Check. Dress shoes? Check. Your diet? That's all too easy to forget. For those whose jobs require frequent travel, a balanced diet all too often goes right out the window along with a balanced work-home life. A study published last year in the Journal of Occupational and Environmental Medicine found that frequent travel not only expands the waistlines of businesspeople, it can also lead to weight-related medical conditions such as high blood pressure and cholesterol levels, especially in those who spend at least 21 nights away from home each month. You're hardly to blame: A hectic schedule coupled with limited dining options on the road are enough to derail the most determined dieter.

But even with the odds stacked against you, there are ways to maintain a healthy lifestyle while on the go, says Elisabetta Politi, nutrition director at the Duke Diet and Fitness Center. Planning ahead can go a long way. "If you have a plan, you're likely to do better because you're not letting your environment control you," she says. Here are a few tips to keep your regimen on track while you're on the road.

Pack some snacks

When packing your bags, make sure to throw in some healthy munchies. "We approach the food environment passively, and we don't do that with any other aspect of the environment," says David Katz, founding director of the Yale-Griffin Prevention Research Center. "If it's cold, we pack warm clothes, and if it's raining, we don't just hope to stay dry. We deal with environmental changes all the time when we travel, and food is no different." Katz recommends that alongside your dress shoes and tie, you throw in some wholesome snacks--like granola or fruit--to help you curb hunger pangs while you're in transit. This will help you stay in control of what you eat. "If I get hungry, the person who's in control of my dietary destiny is me," Katz says. "Not some nincompoop who stocks the vending machine."

Stay on schedule

One of the most challenging feats is sticking to a regular meal schedule while traveling. Flights can get delayed or canceled, stranding you in the airport terminal with nothing but a greasy something to wolf down. Long car trips can provide no option but a rest stop. That's why having healthy snacks with you is so vital. Frequent travelers also face time changes and jet lag, which can quickly derail an otherwise perfectly timed eating schedule. According to Katz--who says this problem also plagues shift workers like nurses and security guards--it doesn't matter when you eat as long as you do so regularly. "Getting used to a new schedule is difficult, and everyone adjusts differently," he says. "If it turns out that 3 a.m. is your time for dinner, then do it. A routine really helps regulate what and how much you eat."

Stay hydrated

People often mistake thirst for hunger, says Politi. Hydrating often can help prevent overeating. The Mayo Clinic recommends that men drink roughly 13 glasses of liquids each day, while women should aim for around nine glasses. But just like your diet, your drink choices can negatively affect your weight. When the drink cart makes its way down the airplane aisle, opt for flat water instead of soda to avoid empty calories (and the tummy growls often caused by carbonation).

Fatty diets may be associated with reduced semen quality, according to a study published Wednesday in the European reproductive medicine journal Human Reproduction.

In a study of 99 U.S. men, researchers found an association between high total fat intake and lower total sperm count and concentration. It also found that men who ate more omega-3 fats (often found in fish and plant oils) had better formed sperm than men who ate less of these types of fats.

"At a global level, adopting these lifestyle modifications may improve general health, as high-saturated fat diets are known to be a risk factor for a range of cardiovascular diseases; but, in addition, our research suggests that it could be beneficial for reproductive health worldwide," said Dr. Jill Attaman, an Obstetrics, Gynecology and Reproductive Biology instructor at Harvard Medical School at the time of the research, in a statement.

"Little is known of how diet may influence male reproductive potential," researchers said in the study.

Men, with an average age of 37 years, who attended a fertility clinic were investigated between December 2006 and August 2010.

Researchers questioned them about their diet and analyzed samples of their semen. Also, 23 of the 99 men participating in the study were measured for levels of fatty acids in their sperm and seminal plasma.

Participants were divided into three groups according to the amount of unsaturated fats they consumed. Men with the third-highest fat intake had a 43 per cent lower sperm count and 38 per cent lower sperm concentration than men in the group with the lowest fat intake.

Men who consumed the most omega-3 fatty acids had slightly more sperm (1.9 per cent) that were "correctly formed" than men in the third that had the lowest intake of omega-3.

Meanwhile, researchers noted some limitations: the study size is small and needs to be replicated by further research to confirm the role of fatty diets on men's fertility, they said. Also, the use of a food frequency questionnaire might not accurately reflect men's actual diets. And only one semen sample per man was collected.

Researchers cautioned that the study can only show an association between dietary fats and semen quality and cannot show causation.

Too much fat in men's diet could lower chances of fertility: Study

ScienceDaily (Mar. 13, 2012) Men's diets, in particular the amount and type of different fats they eat, could be associated with their semen quality according to the results of a study published online in the journal Human Reproduction.

The study of 99 men in the USA found an association between a high total fat intake and lower total sperm count and concentration. It also found that men who ate more omega-3 polyunsaturated fats (the type of fat often found in fish and plant oils) had better formed sperm than men who ate less.

However, the researchers warn that this is a small study, and its findings need to be replicated by further research in order to be sure about the role played by fats on men's fertility. Professor Jill Attaman, who was a Clinical and Research Fellow in Reproductive Endocrinology and Infertility at Massachusetts General Hospital and an Instructor in Obstetrics, Gynecology and Reproductive Biology at Harvard Medical School at the time of the research* said: "In the meantime, if men make changes to their diets so as to reduce the amount of saturated fat they eat and increase their omega-3 intake, then this may not only improve their general health, but could improve their reproductive health too. At a global level, adopting these lifestyle modifications may improve general health, as high saturated fat diets are known to be a risk factor for a range of cardiovascular diseases; but, in addition, our research suggests that it could be beneficial for reproductive health worldwide."

A number of previous studies have investigated the link between body mass index (BMI) and semen quality, with mixed results. However, little is known about the potential role of dietary fats and semen quality, and so Prof Attaman and her colleagues set out to investigate it in men attending a fertility clinic.

Between December 2006 and August 2010 they questioned the men about their diet and analysed samples of their semen; they also measured levels of fatty acids in sperm and seminal plasma in 23 of the 99 men taking part.

The men were divided into three groups according to the amount of fats they consumed. Those in the third with the highest fat intake had a 43% lower total sperm count and 38% lower sperm concentration than men in the third with the lowest fat intake. "Total sperm count" is defined as the total number of sperm in the ejaculate, while "sperm concentration" is defined as the concentration of sperm (number per unit volume). The World Health Organisation provides a definition of "normal" total sperm count and concentration as follows: the total number of spermatozoa in the ejaculate should be at least 39 million; the concentration of spermatozoa should be at least 15 million per ml.

The study found that the relationship between dietary fats and semen quality was largely driven by the consumption of saturated fats. Men consuming the most saturated fats had a 35% lower total sperm count than men eating the least, and a 38% lower sperm concentration. "The magnitude of the association is quite dramatic and provides further support for the health efforts to limit consumption of saturated fat given their relation with other health outcomes such as cardiovascular disease," said Prof Attaman.

Men consuming the most omega-3 fats had slightly more sperm (1.9%) that were correctly formed than men in the third that had the lowest omega-3 intake.

Of note: 71% of all the men in the study were overweight or obese, and the health effects of this could also affect semen quality. However, the researchers made allowances for this. "We were able to isolate the independent effects of fat intake from those of obesity using statistical models," said Prof Attaman. "Notably, the frequency of overweight and obesity among men in this study does not differ much from that among men in the general population in the USA (74%)."

The study is subject to a number of limitations that could affect the results; for instance, the use of a food frequency questionnaire might not accurately reflect men's actual diets, and only one semen sample per man was collected. The authors point out that studies like theirs cannot show that dietary fats cause poor semen quality, only that there is an association between the two.

Fatty diets may be associated with reduced semen quality

Like many others, I started a diet after the new year. I have tried many with little success. Can you please share with me why so many diets just don't work - or at least for me? I have tried diets from the cabbage soup diet, low fat diet, low-carb diet and banana diet to name a few, and while I may lose a little, I always seem to put the weight back on, sometimes even more weight than I lost. It is frustrating and I am at my wits end trying to figure out my next step. Is there a better diet for women? Please help me.

The bottom line is that most diets are a temporary fix for a permanent problem. In order for a diet to work, you should change your eating behaviors (i.e., chew your food properly) and lifestyle (i.e., do not eat at 9 p.m. and go to bed at 10 p.m.), reduce your stress and it should not be an on/off program.

The most effective way to begin a lifestyle change is to gradually add healthier foods, supplement with whole food daily vitamins, drink plenty of good water and incorporate exercise a few times a week.

If you want to lose weight, you will have to eat fewer calories (than you burn daily).

I recommend you choose foods that you can see yourself enjoying, yet they are still nutritious and healthy and you can continue to include those foods in your eating program, even as you age.

Do not cut your calorie intake too dramatically because if you deprive your body of the necessary calories, your body will think you are in the middle of a famine and will do its best to keep you from dying of hunger. By going into starvation mode the body lowers the metabolic rate to preserve fat and energy reserves.

The result is that the body will consume your muscles before it will start on your fat stores because muscle tissue requires the most calories. Your body is very smart and programmed to survive. Unfortunately, we are a society of instant gratification - open something up, zap the contents and hurriedly eat it.

I believe that old saying, "You are what you eat," has a clearer meaning now than ever before. The management of stress plays an integral role in dieting. Be it mental, physical or emotional, stress is not a state of mind.

Studies indicate that regular stress causes a chronic immune response, which is not conducive to weight loss. There are many ways to employ a successful diet, and some diets do work better for some than for others.

The latest video in Diet Cokes Serial Designer campaign has been giving viewers the heebie-jeebies.

I dont know if it is Bernadettes (wooden supermodel puppet) heroine addicted visage or Jean Paul Gautiers molester like grin and awkward groping of her that is responsible for sparking horror within its audience.

This video could be damaging to women because it portrays models as being dumb, heavy drinking, and quick to submit. Gaultier leaves viewers feeling uneasy after he is entrusted to dress the female representation but infringes on professional boundaries by stripping the marionette of her robe and stroking her midsection.

Gaultier has just been appointed as the new creative director for Diet Coke Europe. He will be given the challenge of redesigning the bottles and cans.

Maybe I just dont get it because I am not French and do not enjoy bizarre erotic humor.

Here are some comments posted under the YouTube video:

This is absurd. Totally degrading; women are nothing like that (thank God) and it is nothing but a marketing lie to present diet coke and clothes as something that can make a woman more or less feminine. As if some sugar in water and a few stitched up pieces of cloth with a designer label on them can make one anything more than mainstream and impersonal.

This is soo bad. How exactly does it sell Diet Coke? And moreover its kinda creepy. What a dud!

Not funny and much too late

Absolute craaaap..
