Most people have a sweet tooth. It's the ultimate comfort food. But, that candy bar could make you less manly . A new study claims glucose, i.e. sugar, decreases testosterone levels .

Presented at the Endocrine Society's Annual Meeting, researchers found that of the 74 men tested, 73 had significantly lower levels of testosterone two hours after being administered glucose.

New research reported at this week's meeting of the European Society of Human Reproduction found that men with a history of fertility problems can improve their sperm count by having sex every day. The problem is that recent surveys show that a startling number of Americans are NOT having sex: 40 million live in no-sex, low-sex relationships and 43 percent of men report some form of sexual inadequacy.

Think that statistics refer to men past their prime? Think again. This downhill trend in sexual desire, performance and pleasure is increasingly occurring in younger 20-something and 30-something men. According to Genie James, M.M.Sc., Executive Director of The Natural Hormone Institute, "Environmental hormones are a very real culprit sabotaging both a man's sex life and his sperm count."

Picture this – you are a forty year old man reading the newspaper on a Sunday morning. You used to enjoy this weekly ritual, but you feel irritable today. Actually, you haven’t felt like yourself recently. You are happy with your job and your relationships, but you feel tired and depressed and you don’t know why. You haven’t been sleeping well and your sex life isn’t what it used to be.

Before you reach for another cup of coffee, ask yourself – have I had my testosterone levels checked to see if I have andropause?

Throughout history, many foods, drinks, and behaviors have had a reputation for making sex more attainable and/or pleasurable. An aphrodisiac is a substance which is used in the belief that it increases sexual desire. In particular, medical science has not substantiated claims that any particular food increases sexual desire or performance.

Food eating habits alter libido

Libido means a person's sex drive or sexual urge. Libido does vary from person to person, from female to male. General levels of libido & sex drive decrease slowly as people enter mid life. If you have a lower than normal libido, then eating the right types of foods and cutting down on the wrong foods can help to increase your libido and rebuild your sex drive .

I am middle-aged. In September, I will be 54 years old. Statistically that is actually just about the end of the middle part of my life, and entering into the final stage. An Australian man lives an average of 82 years. Divided into beginning, middle and end, each section would be 27 1/3 years. Given my health history, I would be more than happy to accept a guarantee of living to age 82, so it seems logical that I must accept that my middle age is just about over.

Not so fast. Sure, when I was 18 I would have accepted that 55 was old. I’m from the “never trust anyone over 30” generation. I sang along to The Who’s call of “Hope I die before I get old”. But now that the time is here, I find that I, and seemingly most of my fellow boomers, find it hard to accept the realities of aging. A 65-year-old friend of mine recently said to me the he considered himself middle-aged. Apparently he expects to live 130 years.

Partially it’s the words that are difficult to accept. We go from young, to middle-aged, to old. I suppose senior citizen isn’t quite as bad, and I personally like the idea of being a village elder, but there’s a basic problem with all of them: They remind us we’re closer to the end than the beginning, and that stinks.

Older adults might have some pre-existing immunity to H1N1 swine flu, according to the U.S. Centers for Disease Control and Prevention.

Lab tests showed that some adults, particularly those older than 60, had antibodies against the new strain, but Dr. Anne Schuchat of the CDC cautioned against reading too much into the finding.

Men who suffer from premature ejaculation may be able to blame their genes, work suggests.

A study of nearly 200 Dutch men found those who climaxed too soon during intercourse had a version of a gene that controls the hormone serotonin.

Men with this version ejaculated twice as quickly as other men in the study.
