Study Finds Genetic Link to Herpes Susceptibility

Genetics • • Sexual HealthJan 28 08

There’s a high probability that people who are prone to herpes simplex virus (HSV) outbreaks can inherit that susceptibility through their genes, University of Utah researchers report in a new study.

In the Feb. 1 issue of The Journal of Infectious Diseases, the researchers identify a region on the long arm of human chromosome 21 with high odds—at least 1,000-to-1—of being linked to cold sore susceptibility. The researchers further say they pinpointed six specific genes in that chromosomal region as candidates for making people prone to outbreaks of cold sores (also called “fever blisters”). Cold sores occur when the herpes virus reactivates from its quiescent state within the nerve, infecting the lip, nose, or face.

Discovery of the probable link could lead to the development of new drugs that reduce the frequency of herpes outbreaks, according to John D. Kriesel, M.D., the study’s corresponding author and research associate professor in the U School of Medicine’s Division of Infectious Diseases.

Prostatitis May Effect Up To One-half of All Males During Their Lifetimes

Gender: Male • • Sexual HealthJan 21 08

Estimates on the number of males in the United States who will experience prostatitis during their lifetimes range up to 50 percent. Many urologic disease experts feel that from 5 to 10 percent of males are experiencing prostatitis at a particular time, making it one of the most common urologic diseases in the U.S.

Prostatitis is an infection or inflammation of the prostate gland that causes intense pain, urinary complications, sexual dysfunction, infertility, and a significant reduction in the quality of life Prior to the mid-1990s, very little research had occurred that could lead to improved diagnostic techniques and a cure.

Prostatitis is difficult to diagnose and treat, and has a wide range of debilitating and troublesome side affects. Unlike prostate cancer and benign prostatic hyperplasia (BPH), prostatitis often affects the lives of young and middle-aged men.

Aggression as rewarding as sex, food and drugs

Food & Nutrition • • Psychiatry / Psychology • • Sexual HealthJan 14 08

New research from Vanderbilt University shows for the first time that the brain processes aggression as a reward - much like sex, food and drugs - offering insights into our propensity to fight and our fascination with violent sports like boxing and football.

The research will be published online the week of Jan. 14 by the journal Psychopharmacology.

“Aggression occurs among virtually all vertebrates and is necessary to get and keep important resources such as mates, territory and food,” Craig Kennedy, professor of special education and pediatrics, said. “We have found that the ‘reward pathway’ in the brain becomes engaged in response to an aggressive event and that dopamine is involved.”

Sex Keeps Love Alive Throughout Adult Life

Sexual HealthJan 11 08

Sex, as well as romance, is an important part of couple’s lives and health well into their retirement years. Researchers at the University of Chicago have conducted some of the nation’s most comprehensive studies of sexual behavior, looking at sexuality from early adulthood until late in life. Their work shows that sexuality remains an important part of life as people age and that the frequency of sexual activity, for those who are active, declines only slightly from the 50s to the early 70s.

Daily alcohol use causes changes in sexual behavior, new study reveals

Sexual Health • • Tobacco & MarijuanaJan 03 08

A team of researchers at Penn Sate has used an animal model to reveal, for the first time, a physiological basis for the effect of alcohol on male sexual behavior, including increased sexual arousal and decreased sexual inhibition. The research, which will be published on 2 January 2008 in the scientific journal PLoS ONE, resulted in four novel findings with broad importance for further addiction research. It is the first study to characterize the effects of chronic alcohol exposure in fruit flies.

“Physiological evidence supporting various theories about the effect of alcoholic drinks has been lacking, so our now having a suitable animal model makes it possible to conduct much-needed laboratory research on this issue,” explains research-team-leader Kyung-An Han, associate professor of biology and a neuroscientist at Penn State. Information from this research can serve as a baseline for similar studies in other animals, including humans.

Soy Food Effects on Semen Quality

Sexual HealthOct 31 07

Isoflavones are plant-derived polyphenoloic compounds with weak estrogenic activity found mainly in soybeans and soy-derived products. High isoflavone intake has been reported to be associated with decreased animal fertility. The impact of high isoflavone intake on human fertility is unknown. This Cross-sectional study assesses isoflavone intake in males of sub fertile couples who had semen analyses. The questionnaire was designed to assess intake of 15 soy-based foods in the last three months was collected.

100 men with semen data and completed questionnaires were studied. There was an inverse association between soy food intake and sperm concentration that remained significant when evaluated with respect to age, abstinence, body mass, and caffeine, each of tobacco intake. There was no impact on sperm motility of morphology.

Living fossils have hot sex

Public Health • • Sexual HealthOct 04 07

University of Utah scientists discovered a strange method of reproduction in primitive plants named cycads: The plants heat up and emit a toxic odor to drive pollen-covered insects out of male cycad cones, and then use a milder odor to draw the bugs into female cones so the plants are pollinated.

The unusual form of sexual reproduction used by some species of cycads – primeval plants known as “living fossils” – may represent an intermediate step in the evolution of plant pollination, the researchers report in the Friday, Oct. 5 issue of the journal Science.

The best both of worlds—how to have sex and survive

Sexual HealthSep 20 07

Researchers have discovered that even the gruesome and brutal lifestyle of the Evarcha culicivora, a blood gorging jumping spider indigenous to East Africa, can’t help but be tempted by that ‘big is beautiful’ mantra no matter what the costs. A study recently published in Ethology found that despite the inherent risk of sexual cannibalism, virgin females were attracted to bigger males when losing their virginity before opting for the safer smaller male as a longer term mate choice.

It is quite common for male spiders to fall victim to female sexual partners once they have mated as the female is more often than not bigger than her mate.

Teenage weight may affect later fertility

Obesity • • Sexual HealthSep 15 07

Teenagers who are either underweight or obese are likely to have fewer children in adulthood, a study has found.

It’s known that both obesity and abnormally low body weight are related to reproductive difficulties, and that obesity raises the risk of a number of pregnancy complications. However, it has not been clear whether underweight and obese teenagers go on to have fewer children than their normal-weight peers.
