Buck Institute study sheds light on gender differences in diabetes and aging
All's not fair in love and glucose intolerance -- overweight men (and mice) are more prone to get type 2 diabetes than are overweight women (and mice). No one has known why -- until now. Researchers have discovered that a protein involved in nutrient sensing and metabolism gets differentially inhibited in male mice fed a high fat diet. The findings also show that boosting the protein protects male mice from age-induced obesity and metabolic decline. (2016-08-04)

Possible drug target for obesity treatment a no-brainer: UNC study

Hypertrophic cardiomyopathy under-appreciated cause of sudden cardiac death in male minority athletes
Sudden deaths in young, seemingly healthy competitive athletes are tragic events. In a new study published in The American Journal of Medicine, investigators report that more than one-third of recorded cardiovascular deaths were caused by hypertrophic cardiomyopathy, the majority in young male minority athletes. Sudden deaths due to genetic and/or congenital heart diseases are uncommon in females, but relatively common in African-American and other minorities compared to whites. (2016-06-27)

Male birth control for the malaria parasite
Disrupting two genes involved in the preservation of RNA molecules inhibits the ability of the male form of the malaria parasite to mature and be transmitted from human blood into mosquitoes, interrupting a key stage in the parasite's life-cycle and cutting off an important step in the spread of the disease. (2019-01-31)

Reproduction: How male flies enforce their interests
During mating, both males and females sometimes evolve creative strategies to pursue their interests. Researchers from Münster (Germany) and Lausanne (Switzerland) have now found out: male flies manipulate their partners primarily in order to increase their own chances in reproductive competition. The study was published in the journal PNAS. (2019-04-11)

New Zealand study unlocks secrets of sex change in fish
A University of Otago-led study is heralding advances in our understanding of one of the most startling transformations in the natural world -- the complete reversal of sex that occurs in about 500 species of fish. (2019-07-10)

Unemployment encourages men to try traditionally female-dominated work
A study finds that men who previously worked in male-dominated or mixed-gender fields are significantly more likely to transition to female-dominated jobs following a bout of unemployment, bucking past evidence showing resistance by men to working female-dominated jobs. When they do make the switch, the study finds they reap benefits in wages and job prestige. (2019-12-03)

Cystic fibrosis carriers are at increased risk for cystic fibrosis-related conditions
A University of Iowa study challenges the conventional wisdom that having just one mutated copy of the cystic fibrosis (CF) gene has no effects on a person's health. The findings show that CF 'carriers' are at increased risk for most of the conditions that affect people with CF. Although the individual-level risk is low, more than 10 million Americans are CF carriers, suggesting the amount of illness caused by CF-related conditions could be substantial. (2020-01-08)

What we're learning about the reproductive microbiome
Most research has focused on the oral, skin, and gut microbiomes, but bacteria, viruses, and fungi living within our reproductive systems may also affect sperm quality, fertilization, embryo implantation, and other aspects of conception and reproduction. Yet, according to a review published Jan. 14 in the journal Trends in Ecology & Evolution, little is known about the reproductive microbiome. (2020-01-14)

Gender bias kept alive by people who think it's dead
Workplace gender bias is being kept alive by people who think it's no longer an issue, new research suggests. (2020-06-26)

Herbicide harming marsupial health and development, research finds
Researchers exposed the adult female tammar wallabies to atrazine contaminated water throughout pregnancy, birth and lactation to help establish the extent of harm being caused by the chemical. They then examined the reproductive development of their young by assessing their growth and development to establish that the herbicide is causing major abnormalities in the male reproductive system in many animals. (2020-08-05)

Higher live birth rates found after transferring fresh rather than frozen embryos...
Leveraging national data from the Society for Assisted Reproductive Technology (SART), the Brigham researchers found that, in cycles using freshly retrieved donor eggs, fresh embryo transfers were indeed associated with significantly higher live birth rates compared to frozen embryo transfers. The team's findings are published in JAMA. (2021-01-12)

Stress puts double whammy on reproductive system, fertility
Stress is known to decrease fertility and sexual behavior, but researchers thought this was because stress hormones lower levels of a brain hormone called gonadotropin releasing hormone, or GnRH. UC Berkeley biologists now show that stress hormones also boost levels of a hormone that suppresses GnRH -- a double whammy. The scientists hope it will be possible to block this hormone, called gonadotropin inhibiting hormone, or GnIH, and restore fertility. (2009-06-15)

Male Eurasian jays know that their female partners' desires can differ from their own
Researchers investigated the extent to which males could disengage from their own current desires to feed the female what she wants. (2014-03-25)

Research into cetacean reproduction leads to birth of killer whales by artificial insemination
Research into the reproductive physiology of killer whales has led to the first live births by artificial insemination of any whale species. The scientists who conducted these studies of killer whales say that their work will help ensure the genetic vitality of marine mammals in zoological facilities. (2004-05-12)

Early menopause may occur in women with BRCA gene, new study finds
Women with harmful mutations in the BRCA gene, which put them at higher risk of developing breast and ovarian cancer, tend to undergo menopause significantly sooner than other women, allowing them an even briefer reproductive window and possibly a higher risk of infertility, according to a study led by researchers at UC San Francisco. (2013-01-29)

For females, a little semen may go a long way
For most guys in the animal kingdom, sex is a once-and-done event. Females from species like rabbits and cows get sperm from their mates and not much else. But in a Forum article published March 3 in Trends in Ecology & Evolution, researchers suggest that these limited encounters can supply resources to females in seminal fluid, and females might have evolved to seek out such seminal resources, even when the amount of fluid is small. (2016-03-03)

Shared housing, shared behavior in mouse model of autism
Mice genetically modified to model autism spectrum disorders (ASD) cause changes in the behavior of their unmodified littermates when housed together. The findings, published in eNeuro, show how social environment shapes behaviors characteristic of mouse models for ASD and have implications for the interpretation of results obtained from mouse models of psychiatric disorders. (2017-07-31)

Kisspeptin boosts male sexual appetite and reduces anxiety
Increased activity of the hormone, kisspeptin, enhances sexual attraction and decreases anxiety in male mice, according to new research presented today at the Society for Endocrinology annual conference in Harrogate. The study is the first to identify that kisspeptin has an important role in regulating sexual and social behaviour and may be a new target for tackling male sexual dysfunction and anxiety-related disorders. (2017-11-04)

Proportionally more male bosses negative toward depression
A higher proportion of male than of female managers have negative attitudes toward depression, a University of Gothenburg study shows. The more senior the managerial positions, the bigger the share of men with negative attitudes; the same, moreover, applies to women in senior managerial jobs. (2020-12-14)

Female language style promotes visibility and influence online
A female-typical language style promotes the popularity of talks in the digital context and turns out to be an underappreciated but highly effective tool for social influence. This was shown by UZH psychologists in an international study in which they analyzed 1,100 TED Talks. (2020-12-16)

Men more likely to commit research misconduct than female counterparts
It's not hard to see that men are more likely to engage in risky behaviors than women, or that crime rates are many times higher among men, but this tendency to break the rules also extends to male scientists, according to a study to be published on Jan. 22 in mBio®, the online open-access journal of the American Society for Microbiology. (2013-01-22)

Vaccine for koala chlamydia close

Gender linked to development of skin cancer
Inherent gender differences -- instead of more sun exposure -- may be one reason why men are three times more likely than women to develop certain kinds of skin cancer, say researchers at Ohio State University Medical Center. (2007-04-01)

Indiscriminate nursing in communal breeders: A role for genomic imprinting
Many female mammal species indiscriminately nurse each others' offspring. Previous hypotheses have suggested that the inability to recognize one's own young is the result of costs incurred from recognition errors. An alternative hypothesis based on sexual conflict theory and genomic imprinting is discussed in Ecology Letters, March. Males benefit from indiscriminate nursing of all their offspring and the reduced risk of female infanticide. Paternally expressed genes suppressing kin recognition during lactation is a possible cause. (2003-03-12)

Scientists discover microbiome that may be responsible for male reproductive disorders
Research shows that bacteria can be beneficial to body processes such as digestion; however, some bacteria housed in the human body may cause disease. These specialized communities of bacteria in the body are known as microbiomes. Now, researchers at the University of Missouri have discovered a microbiome in the male reproductive tract in mice that harbors harmful bacteria. In fathers, some bacteria may initiate diseases, such as prostatitis, that can result in later prostate cancer. (2016-03-15)

UCSD study finds women's attitudes can influence drop-out rates among female engineering students
Female engineering students who believe competence in engineering and math is something a person is born with tend to drop out of classes when faced with difficulty, according to a study conducted at the University of California, San Diego (UCSD). (2002-08-01)
