Let's Hear it for Testosterone!


While it may have caused you to lose your hair, extra testosterone may still be your friend. A recent study, reported in the American Heart Association journal Arteriosclerosis and Thrombosis, found that higher testosterone levels appear to be associated with higher levels of good cholesterol and reduced blockages in the arteries of older men.

Alcohol's Effects On Testosterone


Even though testosterone is often referred to as a 'male sex hormone,' it is in actuality common to both genders of animals and humans. The overwhelming majority of research conducted in the past 25 years in both animals and humans has found that alcohol inhibits testosterone secretion. However, a new study in the January issue of Alcoholism: Clinical and Experimental Research has found that acute administration of alcohol can induce a rapid increase in plasma and brain concentrations of testosterone in some rodents.

Testosterone Levels in Older Men Predict Cognitive Status


Relatively high serum free testosterone levels correlate with slower cognitive decline in older men, researchers at the National Institutes on Aging in Baltimore, Maryland, report in the November issue of the Journal of Clinical Endocrinology and Metabolism.

Dr. Scott D. Moffat and colleagues analyzed data on 407 volunteers from the Baltimore Longitudinal Study, who were between the ages of 51 and 91 at baseline and were followed for 10 years.

Subjects performed neuropsychological tests of verbal and visual memory, mental status, visuomotor scanning and attention, verbal knowledge/language, visuospatial ability and symptoms of depression. Serum testosterone and free testosterone levels were measured contemporaneously.

The higher the free testosterone index, the better the cognitive functioning, the researchers report. "Men classified as hypogonadal had significantly lower scores on measures of memory and visuospatial performance and a faster rate of decline in visual memory," Dr. Moffat and colleagues found.

They conclude that "the progressive physiological decline in testosterone secretion in aging men contributes to selective losses in cognitive functions that may be reversed at least in part by testosterone supplementation." Whether such testosterone administration is safe would require larger scale investigations.

Single Men Testosterone Driven


Scientists in the US say single men have higher levels of testosterone than those who are married with children. The researchers, at Harvard University, believe the difference may be linked to men’s daily social interactions, and suggest that constant contact with close family reduces the level of the hormone in married men and encourages them to be faithful. The findings are consistent with those of previous studies showing that rising testosterone levels can cause men to play the field.

Testosterone test offers clue to a man's fidelity


Women interested in knowing whether their men are likely to stray should find out their testosterone levels.

In birds, low levels of the male hormone encourage fidelity while higher levels mean they are more likely to play the field. The same could be true for humans.

Scientists at Harvard University, in America, have found that married men who spend time with their family have lower testosterone levels than bachelors. This could be nature's way of encouraging men with families not to be unfaithful, said the scientists.

When Peter Gray, an anthropologist, and his colleagues measured testosterone in 58 men they found that levels dropped after a natural peak in the morning. But the decrease was more prominent in the married men than in bachelors.

"And fathers seem to show an even more dramatic difference from unmarried men," Mr Gray told New Scientist magazine. So devoted fathers, who are less likely to stray, probably have lower testosterone levels.

Testosterone May Reduce Risk Of Stroke In Men; Estrogen Levels Not Related To Stroke


Higher levels of testosterone are related to lower risk of stroke in men. This lower stroke risk was only seen in men who do not smoke, according to a study presented at the annual meeting of the American Academy of Neurology. Estrogen levels are not related to stroke risk in either men or women.

Testosterone Aids Older Men's Brains


Older men with higher testosterone levels performed better on tests of cognition in a new study from University of California, San Francisco researchers. The study suggests that older men who are prescribed testosterone supplements may reduce their risk of cognitive decline, a precursor state to Alzheimer's disease, the researchers said. However, Yaffe does not recommend that men begin taking testosterone to improve cognition. Taking testosterone, or over-the-counter supplements that boost levels of the hormone, can have side effects including increased risk of prostate cancer.

Men Behaving Sadly? It Might be the Hormones


It's the news all women have been waiting for. Hormones wreak havoc on men's lives too.

Lack of testosterone leaves men bad-tempered, emotional, depressed and suffering from Irritable Male Syndrome, scientist Gerald Lincoln told BBC radio's Today program Thursday.

"It has an amusing side because we realize the frailties of men and how hormones do affect their behavior. But there is a serious side in that men's behavior can be compromised by their hormone state," he said.

Unlike women's hormonal state which moves in cycles, it is extreme circumstances, like accidents or serious illness, which trigger slides in men's hormonal levels, said Lincoln, who works at Edinburgh's Human Reproductive Sciences Unit.

But a shot of testosterone can make it all better with previously withdrawn men showing heightened energy, motivation and sex drive, he added.

It did not however solve the age-old problem of traditional male inability to wash the dishes.

The link between male irritability and testosterone was discussed originally in science journal Reproduction, Fertility and Development.

Testosterone Implants Effective Contraception for Men


Implants that continuously release testosterone suppress sperm production to levels adequate for contraception in approximately 70% of men, researchers report. www.healthcentral.com/news/newsfulltext.cfm?ID=46337&src=n45 (no longer available at the original source.)

'Testosterone revolution' urged for older men


Testosterone supplementation could one day help keep men fit, active and happy well into old age, just as estrogen lends vitality to postmenopausal women, a doctor suggests. www.healthcentral.com/news/newsfulltext.cfm?ID=!46048&src=n45 (no longer available at the original source.)

Try testosterone when you're over the hill


Some doctors have been clamoring for recognition that men have menopause. To check this theory scientists tested the effects of testosterone injections in a double-blind study of healthy men above age 65. The men took standard psychology tests to measure their sense of well being. www.healthcentral.com/drdean/DeanFullTextTopics.cfm?ID=46037&src=n45
