Scientists used genetic sequencing to discover that the vaccine used in the RV144 HIV vaccine trial, involving 16,000 men and women in Thailand, did offer some protection against certain HIV viruses. The results were published Sept. 10 in the online edition of Nature.
James Mullins, UW professor of microbiology, medicine and laboratory medicine, leads one of the two laboratories that did genetic analyses of the virus. He said the study proved that an HIV vaccine is within reach. (more…)
UCLA School of Nursing study shows walnuts improve sperm quality
Eating about two handfuls of walnuts a day may provide men the added boost they need to improve their fertility, according to a breakthrough study by researchers at the UCLA School of Nursing.
Findings from the study, “Walnuts Improve Semen Quality in Men Consuming a Western-Style Diet: Randomized Control Dietary Intervention Trial,” are published Aug. 15 in the “papers in press” section of the peer-reviewed journal Biology of Reproduction.
This is the first study to look at the effects of a plant source of omega-3 on sperm, the researchers say. Statistics from the American Society for Reproductive Medicine show that one in six couples is infertile, with about 40 percent of these cases due to a male factor. (more…)
COLUMBUS, Ohio – Caring for a wife with breast cancer can have a measurable negative effect on men’s health, even years after the cancer diagnosis and completion of treatment, according to recent research.
Men who reported the highest levels of stress in relation to their wives’ cancer were at the highest risk for physical symptoms and weaker immune responses, the study showed. (more…)
COLUMBUS, Ohio – Men may think about sex more often than women do, but a new study suggests that men also think about other biological needs, such as eating and sleep, more frequently than women do, as well.
And the research discredits the persistent stereotype that men think about sex every seven seconds, which would amount to more than 8,000 thoughts about sex in 16 waking hours. In the study, the median number of young men’s thought about sex stood at almost 19 times per day. Young women in the study reported a median of nearly 10 thoughts about sex per day. (more…)
AUSTIN, Texas — Men are more than twice as likely to continue dating a girlfriend who has cheated on them with another woman than one who has cheated with another man, according to new research from a University of Texas at Austin psychologist.
Women show the opposite pattern. They are more likely to continue dating a man who has had a heterosexual affair than one who has had a homosexual affair. (more…)
ANN ARBOR, Mich.— The last-minute holiday dash is on: Men tend to rush in for their prized item, pay, and leave. Women study the fabrics, color, texture and price.
The hunting and gathering ritual of yesteryear continues today in malls around the world. Understanding the shopping behavior of your partner can help relieve stress at the stores, according to a researcher at the University of Michigan. (more…)

EAST LANSING, Mich. — Researchers have long argued that marriage generally reduces illegal and aggressive behaviors in men. It remained unclear, however, if that association was a function of matrimony itself or whether less “antisocial” men were simply more likely to get married.
The answer, according to a new study led by a Michigan State University behavior geneticist, appears to be both.
In the December issue of the Archives of General Psychiatry, S. Alexandra Burt and colleagues found that less antisocial men were more likely to get married. Once they were wed, however, the marriage itself appeared to further inhibit antisocial behavior.
“Our results indicate that the reduced rate of antisocial behavior in married men is more complicated than we previously thought,” said Burt, associate professor of psychology. “Marriage is generally good for men, at least in terms of reducing antisocial behavior, but the data also indicate that it’s not random who enters into the state of marriage.” (more…)
*Researchers urge appropriate use of androgen deprivation therapy*
ANN ARBOR, Mich. — Men treated with hormone-based therapy for prostate cancer faced a 30 percent to 40 percent higher risk of colorectal cancer, compared to patients who did not receive this treatment, according to a new study.
The study looked at use of androgen deprivation therapy, a common type of treatment for prostate cancer that involves blocking the male hormone testosterone through either surgical removal of the testicles or a series of injections. It’s been shown to benefit men with advanced cancers, but its benefit for less-advanced disease is unclear. Still, more than half a million men in the United States currently receive this therapy.(more…)
