There is not one kind of ‘good sperm’ — it depends on other qualities in the male

Leave a comment

In a study published in Behavioral Ecology researchers from Uppsala University show that the same type of sperm is not always the best for all male birds. Depending on how attractive or dominant you are you might be more successful with longer or shorter sperm.

Getting a big family can be a difficult business in nature. If you are a male bird, you have to work hard to secure a territory where you will find food for your chicks and convince a lady that you are both good looking enough and also will be a good dad. But getting a mating partner is not the end of the story, you also need to fertilize her eggs, preferably all of them!

For this, you will need good sperm: sperm that is good at fertilizing eggs, but not only, it also has to be BETTER than the sperm of your potential rivals, that is other males your partner might be copulating with before laying all of her eggs. This happens often in nature, because females do not want to put all of their eggs in the same basket and it might be advantageous instead to have some genetic variation among your offspring.

Determining what makes for a good or attractive male is not always easy, and measuring what makes a good sperm is even harder. Now these two important components of fertilization success are often also measured separately, and we do not really understand how they are linked.

The researchers studied this in collared flycatchers (small black and white birds), by catching close to 120 different males over 4 years, measuring their white forehead patch (used to attract females), their sperm morphology (under the microscope), and their paternity success (i.e. how many of the chicks in their nests were theirs, by analyzing the blood of over 400 six-days old nestlings).

The team found that different categories of males have different sperm morphology, depending on if they manage to secure a territory and have a social mating partner, but also on their age and attractiveness. But most interestingly, the researchers found that the type of sperm that allows them to maximize the number of nestlings they father is different for different types of males. For males that have small forehead patches and are thus less dominant and less attractive, having long sperm is beneficial. This could be because they are more exposed to sperm competition and long sperm are likely to swim faster and reach the egg first.

But longer is not always better! For more attractive males, it is quite the opposite, and having smaller sperm allows them to sire more eggs in their nest.

“Many studies have attempted to link attractiveness and sperm quality, trying to figure out if “sexier” males also have better sperm, with very inconsistent results between studies. Our study shows that what makes a good quality sperm might instead depend on how attractive, competitive, and how old a male is, so there is not one single kind of “good sperm”, and we should more often look at the full picture and actually measure which phenotypes result in the highest fertilization success”, says lead author Murielle Ålund, now researcher at Michigan State University.

Testosterone Therapy: “Significant Reduction” in Heart Attack, Stroke Risks

Leave a comment

Large-scale Veterans Affairs database study reaffirms safety and benefits of testosterone replacement, in men.

A US Veterans Affairs database study of more than 83,000 male subjects found that men whose low testosterone was restored to normal through gels, patches, or injections had a lower risk of heart attack, stroke, or death from any cause, versus similar men who were not treated.  Rajat Barua and colleagues analyzed data collected on 83,010 male veterans with documented low total testosterone levels, dividing them into three clinical groups: those who were treated to the point where their total testosterone levels returned to normal (Group 1); those who were treated but without reaching normal (Group 2); and those who were untreated and remained at low levels (Group 3).  Importantly, all three groups were “propensity matched” so the comparisons would be between men with similar health profiles. The researchers took into account a wide array of factors that might affect cardiovascular and overall risk. The average follow-up across the groups ranged from 4.6 to 6.2 years. The sharpest contrast emerged between Group 1 (those who were treated and attained normal levels) and Group 3 (those whose low testosterone went untreated). The treated men were 56% less likely to die during the follow-up period, 24%less likely to suffer a heart attack, and 36%less likely to have a stroke.  The differences between Group 1 and Group 2 (those who were treated but did not attain normal levels) were similar but less pronounced.  The study authors conclude that: “normalization of [total testosterone] levels after [testosterone replacement therapy] was associated with a significant reduction in all-cause mortality, [myocardial infarction], and stroke.”

New ways to conquer sleep apnea compete for place in bedroom

Leave a comment

Every night without fail, Paul Blumstein straps on a mask that prevents him from repeatedly waking up, gasping for air.

It’s been his routine since he was diagnosed with a condition called sleep apnea. While it helps, he doesn’t like wearing the mask.

“It’s like an octopus has clung to my face,” said Blumstein, 70, of Annandale, Virginia. “I just want to sleep once in a while without that feeling.”

It’s been two decades since doctors fully recognized that breathing that stops and starts during sleep is tied to a host of health issues, even early death, but there still isn’t a treatment that most people find easy to use.

Airway pressure masks, the most common remedy, have improved in design, getting smaller and quieter, but patients still complain about sore nostrils, dry mouths and claustrophobia.

Now, new ways of conquering sleep apnea, and the explosive snoring that comes with it, are vying for a place in the bedrooms of millions of people craving a good night’s sleep. Products range from a $350 restraint meant to discourage back sleeping to a $24,000 surgical implant that pushes the tongue forward with each breath.

Mouthpieces, fitted by dentists, work for some people but have their own problems, including jaw pain. Some patients try surgery, but it often doesn’t work. Doctors recommend weight loss, but diet and exercise can be challenging for people who aren’t sleeping well.

So far, no pills for sleep apnea exist, but researchers are working on it. One drug containing THC, the active ingredient in marijuana, showed promise in a study this year.

What is sleep apnea? In people with the condition, throat and tongue muscles relax and block the airway during sleep, caused by obesity, aging or facial structure. They stop breathing, sometimes for up to a minute and hundreds of times each night, then awake with loud gasping and snoring. That prevents them from getting deep, restorative sleep.

They are more likely than others to have strokes, heart attacks and heart rhythm problems, and they’re more likely to die prematurely. But it’s hard to tease out whether those problems are caused by sleep apnea itself, or by excess weight, lack of exercise or something else entirely.

For specialists, the first-choice, most-studied remedy remains continuous positive airway pressure, or CPAP. It’s a motorized device that pumps air through a mask to open a sleeper’s airway. About 5 million Americans have tried CPAP, but up to a third gave up during the first several years because of discomfort and inconvenience.

Martin Braun, 76, of New York City stopped using his noisy machine and awkward mask, but now he’s trying again after a car crash when he fell asleep at the wheel. “That’s when I realized, OK this is serious stuff already,” said Braun, who has ordered a quieter CPAP model.

Sleep medicine is a relatively new field. The most rigorous studies are small or don’t follow patients for longer than six months, said Dr. Alex Krist of Virginia Commonwealth University, who served on a federal guidelines panel that reviewed sleep apnea treatments before recommending against screening adults who have no symptoms.

“We don’t know as much about the benefits of treating sleep apnea as we should,” said Krist, vice-chair of the U.S. Preventive Services Task Force.

While scientists haven’t proved CPAP helps people live longer, evidence shows it can reduce blood pressure, improve daytime sleepiness, lessen snoring and reduce the number of times a patient stops breathing. CPAP also improves quality of life, mood and productivity.

With noticeable results, many CPAP users, even those like Blumstein with a love-hate relationship with their devices, persist.

Blumstein was diagnosed about 15 years ago after he fell asleep behind the wheel at a traffic light. He shared his frustrations with using a mask at a recent patient-organized meeting with the Food and Drug Administration, as did Joelle Dobrow of Los Angeles, who said it took her seven years to find one she liked.

“I went through 26 different mask styles,” she said. “I kept a spreadsheet so I wouldn’t duplicate it.”

Researchers are now focused on how to get people to use a mask more faithfully and predicting who is likely to abandon it and could start instead with a dental device.

“It’s the bane of my existence as a sleep doctor,” said Dr. James Rowley of Wayne State University in Detroit. “A lot of what sleep doctors do in the first few months after diagnosis is help people be able to use their CPAP.”

Getting it right quickly is important because of insurers’ use-it-or-lose-it policies.

Medicare and other insurers stop paying for a rented CPAP machine if a new patient isn’t using it enough. But patients often have trouble with settings and masks, with little help from equipment suppliers, according to Dr. Susan Redline of Brigham and Women’s Hospital in Boston.

All told, it can drive people toward surgery.

Victoria McCullough, 69, of Escondido, California, was one of the first to receive a pacemaker-like device that stimulates a nerve to push the tongue forward during sleep. Now, more than 3,000 people worldwide have received the Inspire implant. Infections and punctured lungs have been reported; the company says serious complications are rare.

McCullough said she asked her doctor to remove the device soon after it was activated in 2015.

“It was Frankenstein-ish. I didn’t like it at all,” McCullough said. “My tongue was just thrashing over my teeth.”

Others like the implant. “My quality of life is 100 percent better,” said Kyleene Perry, 74, of Edmonds, Washington, who got one in February after struggling with CPAP for two years. “People are saying, ‘You look so much better.’ I have a lot more energy.”

The THC pill, known as dronabinol, already is used to ease chemotherapy side effects. A small experiment in 73 people suggests it helps some but wasn’t completely effective. It may work better in combination with CPAP or other devices, said researcher David Carley of the University of Illinois at Chicago. He owns stock in Respire Rx Pharmaceuticals, which has a licensing agreement with the university for a sleep apnea pill.

As the search for better treatments continues, listening to patients will be key, said Redline.

“We are actually just treating a very tiny percentage of people effectively,” she said.

Cancer: Can testosterone improve patients’ quality of life?

Leave a comment

Cachexia is a condition characterized by loss of body mass — including muscular atrophy — that is usually accompanied by severe weakness and fatigue. Many people who go through cancer experience this.

Studies have noted that “[a]pproximately half of all patients with cancer experience cachexia,” severely impairing their quality of life.

It appears to be “responsible for the death of 22 [percent] of cancer patients.”

What exactly causes this condition — which appears in some patients but not in others — remains unclear, and options to manage and address it are scarce.

But recently, researchers from the University of Texas Medical Branch in Galveston — led by Dr. Melinda Sheffield-Moore, from the Department of Health and Kinesiology — have been investigating the potential of administering testosterone in addition to chemotherapy in order to ameliorate the impact of cachexia.

We hoped to demonstrate these [cancer] patients [who received testosterone treatment] would go from not feeling well enough to even get out of bed to at least being able to have some basic quality of life that allows them to take care of themselves and receive therapy.”

Dr. Melinda Sheffield-Moore

The researchers’ findings — now published in the Journal of Cachexia, Sarcopenia and Muscle — confirm that administering testosterone to individuals experiencing cachexia can, in fact, improve their quality of life to some extent, by restoring some independence of movement.

Adjuvant testosterone shows promise

The most widely used approach to manage cachexia is special nutrition treatments, but these often fail to prevent or redress the loss of body mass.

So, Dr. Sheffield-Moore and team decided to investigate the potential of testosterone based on existing knowledge that this hormone can help build up muscle mass.

“We already know that testosterone builds skeletal muscle in healthy individuals,” she says, “so we tried using it in a population at a high risk of muscle loss, so these patients could maintain their strength and performance status to be able to receive standard cancer therapies.”

In order to test this theory, the scientists worked — for 5 years — with volunteers who had been diagnosed with squamous cell carcinoma, which is a type of skin cancer.

The patients received chemotherapy, radiotherapy, or both, in order to treat the cancer. For 7 weeks during their treatment, some also received a placebo (the control cohort), while others received testosterone.

Dr. Sheffield-Moore and colleagues noticed that the participants who had been given extra testosterone had maintained total body mass and actually increased lean body mass (body mass minus body fat) by 3.2 percent.

“Patients randomized to the group receiving testosterone as an adjuvant to their standard of care chemotherapy and/or radiation treatment also demonstrated enhanced physical activity,” she continues.

“They felt well enough to get up and take care of some of their basic activities of daily living, like cooking, cleaning, and bathing themselves,” says Dr. Sheffield-Moore.

This effect could make a world of difference to people with cancer, as it allows them to maintain more autonomy.

At present, she and her team are looking to describe cancer patients’ muscle proteomes — the totality of proteins found in skeletal muscles — so as to understand how cancer in general, and specifically cachexia, affects their composition.

According to Dr. Sheffield-Moore, “What the proteome tells us is which particular proteins in the skeletal muscles were either positively or negatively affected by testosterone or by cancer, respectively.”

“It allows us to begin to dig into the potential mechanisms behind cancer cachexia,” she claims.

The scientists’ ultimate goal is to be able to support individuals likely to experience cachexia in continuing to support standard cancer treatment, and maintaining, as much as possible, their quality of life.

Low sperm count not just a problem for fertility

Leave a comment

A man’s semen count is a marker of his general health, according to the largest study to date evaluating semen quality, reproductive function and metabolic risk in men referred for fertility evaluation. The study results, in 5,177 male partners of infertile couples from Italy, will be presented Sunday at ENDO 2018, the Endocrine Society’s 100th annual meeting in Chicago, Ill.

“Our study clearly shows that low sperm count by itself is associated with metabolic alterations, cardiovascular risk and low bone mass,” said the study’s lead investigator, Alberto Ferlin, M.D., Ph.D. He recently moved as associate professor of endocrinology to Italy’s University of Brescia from the University of Padova, where the study took place in collaboration with professor Carlo Foresta, M.D.

“Infertile men are likely to have important co-existing health problems or risk factors that can impair quality of life and shorten their lives,” said Ferlin, who is also president of the Italian Society of Andrology and Sexual Medicine. “Fertility evaluation gives men the unique opportunity for health assessment and disease prevention.”

Specifically, Ferlin and his colleagues found that about half the men had low sperm counts and were 1.2 times more likely than those with normal sperm counts to have greater body fat (bigger waistline and higher body mass index, or BMI); higher blood pressure (systolic, or top reading), “bad” (LDL) cholesterol and triglycerides; and lower “good” (HDL) cholesterol. They also had a higher frequency of metabolic syndrome, a cluster of these and other metabolic risk factors that increase the chance of developing diabetes, heart disease and stroke, the investigators reported. A measure of insulin resistance, another problem that can lead to diabetes, also was higher in men with low sperm counts.

Low sperm count was defined as less than 39 million per ejaculate, a value also used in the U.S. All the men in the study had a sperm analysis as part of a comprehensive health evaluation in the university’s fertility clinic, which included measurement of their reproductive hormones and metabolic parameters.

The researchers found a 12-fold increased risk of hypogonadism, or low testosterone levels, in men with low sperm counts. Half the men with low testosterone had osteoporosis or low bone mass, a possible precursor to osteoporosis, as found on a bone density scan.

These study findings, according to Ferlin, suggest that low sperm count of itself is associated with poorer measures of cardiometabolic health but that hypogonadism is mainly involved in this association. He cautioned that their study does not prove that low sperm counts cause metabolic derangements, but rather that sperm quality is a mirror of the general male health.

The bottom line, Ferlin stressed, is that treatment of male infertility should not focus only on having a child when diagnostic testing finds other health risks, such as overweight, high cholesterol or high blood pressure.

“Men of couples having difficulties achieving pregnancy should be correctly diagnosed and followed up by their fertility specialists and primary care doctor because they could have an increased chance of morbidity and mortality,” he said.

###

The researchers will discuss the study during a press conference Sunday, March 18 at 9 a.m. Central. Register to view the live webcast at endowebcasting.com.

Got ED?

Leave a comment

Are struggling with erectile dysfunction? Impotence is a common problem among men and is characterized by the consistent inability to sustain or maintain an erection. Did you know stress, smoking, poor diet, depression, being overweight, and a sedentary lifestyle can increase your chances of developing ED? Here are some additional facts about ED:

1️⃣It is estimated that half of all men between the ages of 40 and 70 suffer from erectile dysfunction to some degree.
2️⃣Although not exactly defined, failure to achieve an erection more than 50 percent of the time is generally considered by medical professionals as erectile dysfunction.
3️⃣Erectile dysfunction can be caused by a number of issues, including hormonal imbalance, a restriction in the flow of blood to your penis, conditions affecting your nervous system, and psychological causes such as depression and anxiety.
4️⃣Taking certain medications can cause erectile dysfunction.

These may include but not limited to: diuretics, antidepressants, corticosteroids, and antihistamines. Testosterone replacement therapy can be an effective treatment for erectile dysfunction.

Scientists Pinpoint Bacteria Likely to Cause Bowel Cancer

Leave a comment

New Zealand scientists have identified a toxic bug they believe may cause bowel cancer and could lead to a life-saving vaccine or early detection test for the too-often deadly disease.

The University of Otago, Christchurch, researchers found a toxic form of a bacteria called Bacteroides fragilis in the gut of almost 80 percent of people with a pre-cancerous lesion — a precursor to the disease.

Bacteroides fragilis is a common bug in our gut, and for the most part, helps with digestion and the general health of the colon. However, in some people the bug produces a toxin that disrupts the cells that line the gut and starts the process of cancer in the bowel.

More than 1,300 New Zealanders die of bowel cancer every year. The disease is becoming increasingly common in people under the age of 50, which could be due to changes in our diet. Diet has a direct influence on our gut health, and the microorganisms living there.

In a world-first, the researchers tracked the progress of 150 people who had undergone a colonoscopy. They genetically analyzed the DNA of samples of bowel taken during the colonoscopies to see if Bacteroides fragilis was present. Between 12 and 15 years after their initial colonoscopy, 79 percent of patients with the toxic Bacteroides fragilis in their gut had developed low grade dysplasia, which is a type of pre-cancer.

Professor Frank Frizelle, head of the University of Otago, Christchurch, research team and a bowel cancer surgeon describes the study findings as a “game-changer.”

“It gives us a clue as to what is actually driving the cancer, and in doing so, it gives us a possible means of being able to manage it.”

With further time and money, the discovery could be used to screen for people with the bug, and it could be used to develop a lifesaving vaccine.

“The earlier you can catch a disease, the better the prognosis. We want study this bug and its impact further with a view to using it as a way to identify people who are at the highest risk of developing the disease, before it takes hold. As a surgeon you can treat one person at a time, if we can prevent the cancer from beginning or treating people as early as possible, that’s the goal.”

Want To Make Real Gym Progress? Deload!

Leave a comment

If pushing it to your limits is your M.O., it might be high time for you to back off a bit and deload. By following the “I don’t need no stinkin’ break” approach to lifting, many lifters don’t make room in their program for deloading. That’s a shame because ratcheting back from your max workout can do your body a world of good.

The Lowdown On Deloading

Many lifters organize their workouts based on the principle of overloading, in which you add more and more challenges over time. These challenges can come in the form of progressively more weight, more volume, or less rest. It’s an effective technique but it can torch your body if you don’t occasionally slow down.

A deload is a period of time, usually about a week, when you back off the intensity of your workout after a long phase of overloading. People often do it when they reach—and can’t overcome—a persistent state of fatigue.

Why Slow Down? I’m Doing Great!

Many people think that taking the time to deload will shift their gains into reverse. I mean, why work so hard each day only to let your intensity slide?  You’ll just lose strength, right? In fact, it’s precisely because you’ve been working so hard that you need to deload.

Deloading doesn’t mean you’re stopping. It usually means switching to weights that are about half what you normally lift and cutting your volume in half.  It’ll make your workout feel incredibly easy, but that’s the point. The human body can take only so much stress. Without a break in intensity, you’ll burn yourself out, fatigue your body beyond its ability to recover, become injured, or all three.

Think of deloading as proactive damage control. By making it a regular part of your training program, you can keep progressing—without having to take much longer breaks when your body gives out.

Deloading gives your joints and tendons a chance to heal and your muscles time to fully recover. This will strengthen your body and mind over time. Constantly pushing 100 percent each workout can be psychologically taxing. You might think you are tough and can take it, but this is exactly how burnout takes place.

Making The Most Of Your Deload Period

Do Cardio… Mellow Cardio

During your deload period, add some light to moderate cardio training to your workout. Avoid high intensity training (HIT) or you’ll be swapping one form of strenuous exercise for another. Cardio, done in moderation, helps the recovery process by improving blood circulation to bring more nutrients and oxygen to damaged muscle tissues.[1] It’s also a great way to relieve soreness.

Aim for 20-30 minutes of light cardio training 3-4 times during your week of deloading.

Perfect Your Form

Since you’ll be lifting much lighter weights during this period, use the opportunity to focus on form. Correct any bad habits you notice so you can see better results and avoid injury once you get back to your normal workout.

Also use this time to work on developing a stronger mind-muscle connection. If you’re doing triceps pull-downs, focus on your triceps and make sure they’re doing the work and not your abs. If you’re doing back exercises, tune in to your scapula and keep your arms out of it.

Learn Some New Exercises

Deloading is also a good time to integrate some new exercises into your program. Once you finish the deload, you’ll get back to your regular program and there’s no better way to ensure continued progress than to keep switching up your exercises.

Adding new exercises can cause soreness, so start out with light weights. You don’t want to deal with delayed-onset muscle soreness (DOMS) while you’re deloading—or any other time, for that matter. The deload period is a chance for your muscles to recover, not get damaged. Take it easy and give your body time to learn new movement patterns.

Make More Time For Sleep

Because a deload week is pretty easy, you’re able to combine a few workouts into one, to the point where you can probably do a full-body run-through in an hour or so. This will help you cut back your weekly gym schedule from five days to maybe two days, freeing up big chunks of time for recovery—and for sleep.

Use these extra hours to take naps instead of hitting the gym, or just go to bed earlier. Sleep is when the body heals itself; the more sleep you get during this week, the more effective your deload will be and the stronger you’ll feel when you get back to your program.

Too many of us try to get by on as little sleep as possible. This does your training no favors. Consider eight hours a night an effective minimum to strive for.

Avoid Slashing All Carbs

Deloading isn’t the time to slash carbs. Many people think that since they’re lowering their training intensity they need to lower their calorie and carb intake too, but don’t be so sure.

The purpose of a deload is to help your body recover from intense, challenging physical activity. As you ratchet back your workout, make sure your body is getting all the carbs it needs to restore muscle glycogen and rebuild lean muscle mass tissue.

It might make sense to decrease your carb intake slightly if you were doing a high-volume workout right before you deload.  If that’s the case, don’t decrease your carbs too much or your results will suffer.

The period of deloading might seem like a radical shift from your regular routine, but it’s only for a week or so—just long enough to give your body a chance to gather its strength again before you start piling on the plates.

Artificial Sweeteners Linked To Obesity And Diabetes

Leave a comment

People are becoming more health conscious and are bending towards use of artificial sweeteners, especially zero calorie ones. These replacements sugars have been demonstrated to be likely to cause health changes which are associated with obesity and diabetes.

 Worldwide these artificial sweeteners have become one of the most common food additives which are used. They can be found in a wide variety of beverages and food items including diet soda. One of the largest populations was looked at to investigate the effects of these artificial sweeteners and what they are capable of doing within the body, and metabolism of sweeteners and sugar after consumption; and the effects on blood vessel health. Results of this study were presented at the 2018 Experimental Biology Meeting.

 Model rats were fed diets which were high in fructose or glucose or acesulfame potassium, or aspartame; which are natural and zero calorie artificial sweeteners. Differences in concentrations of amino acids, fats, and other blood parameters observed within the animals after 3 weeks of being on the diets, specifically acesulfame potassium was found to be accumulating with in the blood and in higher concentrations damaging the blood vessel wall linings.

There has been a significant rise in diabetes and obesity despite the use of non-caloric artificial sweeteners. Researchers explain that this study shows that both artificial sweeteners and sugar have negative effects on the body which leads to diabetes and obesity, with the mechanisms for the cause of obesity differing for both.

When there was an overload of sugar machinery which handles them breaks down. Non-caloric artificial sweeteners lead to negative changes in metabolism, energy, and fat. More research is required on the subject, but results are enough to show high dietary sugars and artificial sweeteners do have negative health outcomes.
