The Flu Vaccine Is Little Effect On Men

The Flu Vaccine Is Little Effect On Men.
The flu vaccine is less in operation for men than women, and researchers at Stanford University hold they've figured out why. The man's hormone testosterone causes genes in the immune way to produce fewer antibodies, or defense mechanisms, in response to the vaccine, they found extenderdlx.com. "Men, typically, do worse than women in protected response to infection and vaccination," said Stanford research mate David Furman, the lead study investigator.

For instance, men are more susceptible to bacterial, viral, fungal and parasitic infection than women. And men's untouched systems don't come back as robustly as women's to vaccinations against flu, yellow fever, measles, hepatitis and many other diseases source. For the study, published online Dec 23, 2013 in the Proceedings of the National Academy of Sciences, the researchers analyzed the blood of nearly 90 adults after they received a seasonal flu shot.

Men with the highest testosterone levels had the worst answer to the flu vaccine across the board. Testosterone is tied to standard manful reproductive characteristics, such as muscle strength, beard growth and risk-taking. "We found a set of genes in men that when activated caused a lousy response to the vaccine, but were not involved in female response. Some of these genes are regulated by testosterone".

It's testosterone's obtain on these genes that causes the poor vaccine response. "This has a lot of implications for vaccine development". Vaccine reaction might be better if men were given twice the dose, he suggested, or possibly if testosterone levels were reduced. The whole picture isn't quite clear or simple. Men's weaker response to the flu vaccine is only seen for some strains of flu.

Some Elderly Men Really Suffer From Andropause, But Much Less Frequently Than Previously Thought

Some Elderly Men Really Suffer From Andropause, But Much Less Frequently Than Previously Thought.
In describing a set of substantial symptoms for "male menopause" for the basic time, British researchers have also resolute that only about 2 percent of men venerable 40 to 80 suffer from the condition, far less than previously thought. Male menopause, also called "andropause" or late-onset hypogonadism, reputedly results from declines in testosterone production that occur later in life, but there has been some moot on how real the phenomenon is, the study authors noted vaginal. "Some aging men doubtless suffer from male menopause.

It is a genuine syndrome, but much less common than previously assumed," concluded Dr Ilpo Huhtaniemi, elder author of a study published online June 16 in the New England Journal of Medicine malayalam. "This is foremost because it demonstrates that genuine symptomatic androgen deficiencies androgens are man's hormones is less common than believed, and that only the right patients should get androgen treatment," added Huhtaniemi, a professor of reproductive endocrinology in the area of surgery and cancer at Imperial College London.

Many men have been taking testosterone supplements to joust the perceived effects of aging, even though it's not assured if taking these supplements help or if they're even safe. The result has been mass confusion, not only as to whether male menopause exists but also how to gift it. "A lot of people abuse testosterone who shouldn't and a lot of men who should get it aren't," said Dr Michael Hermans, an confederate professor of surgery in the Texas A&M Health Science Center College of Medicine and supervisor of the section of andrology, male sexual dysfunction and manly infertility at Scott & White in Temple, Texas.

Human Growth Hormone (HGH) Enhances Athletic Performance Like Testosterone

Human Growth Hormone (HGH) Enhances Athletic Performance Like Testosterone.
Human excrescence hormone, a material frequently implicated in sports doping scandals, does seem to rise athletic performance, a new study shows. Australian researchers gave 96 non-professional athletes age-old 18 to 40 injections of either HGH or a saline placebo. Participants included 63 men and 33 women. About half of the manly participants also received a second injection of testosterone or placebo.

After eight weeks, men and women given HGH injections sprinted faster on a bicycle and had reduced cushy oceans and more lean body mass. Adding in testosterone boosted those goods - in men also given testosterone, the impact on sprinting ability was nearly doubled. HGH, however, had no objective on jumping ability, aerobic capacity or strength, measured by the ability to dead-lift a weight, nor did HGH inflation muscle mass.

So "This paper adds to the scientific evidence that HGH can be effectuation enhancing, and from our perspective at World Anti-Doping Agency (WADA), lends support to bans on HGH," said Olivier Rabin, WADA's realm director. The study, which was funded in cause by WADA, is in the May 4 issue of the Annals of Internal Medicine. Human growth hormone is in the midst the substances banned by the WADA for use by competitive athletes.

HGH is also banned by Major League Baseball, though the combine doesn't currently test for it. HGH has made headlines in the sports world. Recently, American tennis sportswoman Wayne Odesnik accepted a voluntary suspension for importing the import into Australia, while Tiger Woods denied using it after the assistant to a prominent sports medicine learned who had treated Woods was arrested at the US-Canada border with HGH.

However, based on anecdotal reports and athlete testimonies, HGH is extensively abused in professional sports, said Mark Frankel, superintendent of the scientific freedom, responsibility and law program for the American Association for the Advancement of Science. Prior digging has suggested HGH reduces fat mass as well as help the body recover more quickly from wound or "microtraumas" - small injuries to the muscles, bones or joints that occur as a result of consuming training. That type of a boost could put athletes at a competitive advantage.

A New Prostate Cancers Treatment Strategy

A New Prostate Cancers Treatment Strategy.
Conventional long-headedness has it that turned on levels of testosterone help prostate cancers grow. However, a new, small retreat suggests that a treatment strategy called bipolar androgen therapy - where patients stand-in between low and high levels of testosterone - might make prostate tumors more responsive to measure hormonal therapy. As the researchers explained, the primary treatment for advanced prostate cancer is hormonal therapy, which lowers levels of testosterone to retard the tumor from growing. But there's a problem: Prostate cancer cells inevitably beaten the therapy by increasing their ability to suck up any leftover testosterone in the body.

The new strategy forces the tumor to respond again to higher testosterone levels, serving to reverse its resistance to standard therapy, the researchers say. If confirmed in several developing larger trials, "this could lead to a new treatment approach" for prostate cancers that have grown unaffected to hormonal therapy, said lead researcher Dr Michael Schweizer, an subordinate professor of oncology at the University of Washington School of Medicine in Seattle.

So "It needs to be stressed that bipolar androgen remedy is not ready for adoption into routine clinical practice, since these studies have not been completed. The backfire was published Jan 7, 2015 in the journal Science Translational Medicine. For the study, 16 men with hormone therapy-resistant prostate cancer received bipolar androgen therapy. Of these patients, seven had their cancer go into remission. In four men, tumors shrank, and in one man, tumors disappeared completely, the researchers report.
