The research, which analyzed data from nearly 4,000 adults, highlights the complex relationship between hormones and human sexuality.
A preclinical study found that female mice are more susceptible to binge drinking due to a brain circuit called the bed nucleus of the stria terminalis (BNST). The BNST is more excitable in females, requiring stronger inhibition to curb excessive alcohol consumption. This natural 'brake' mechanism may also contribute to sex differences...
A new study of 1328 South Australian high school students aged 13 and 14 found a relatively low proportion admitted to 'sexting' via various electronic mediums. The researchers suggest building a health safety education framework for adolescents to provide skills to navigate pornography as part of sexual education.

The research found no differences in likelihood of contracting STIs or age of first sexual activity between autistic and non-autistic individuals.
A University of Massachusetts Amherst scientist suggests that rising social stress may contribute to the projected global population decline starting in 2064. Stress from social media and other social interactions may be leading to changes in reproductive behavior and physiology, resulting in decreased reproduction rates.
A recent study published in Nature Human Behaviour has identified hundreds of genetic variants that influence the timing of first sex and birth. The research, led by Professor Melinda Mills, found that these genetic markers interact with environmental factors to shape reproductive behavior and later life disease risk.

The researchers discovered that this bias motivates individuals to take a leap of faith and initiate relationships.
A UC Davis Health study found that children with autism born to mothers who had immune conditions during their pregnancy are more likely to have behavioral and emotional problems. Maternal immune conditions, such as asthma, were associated with increased behavioral and emotional problems in male offspring.
Researchers found that approximately 3.3% of families engage in 'coupon-collection behavior', where they have children of both sexes except for the last-born child, reducing sex-ratio variation. The trend is more pronounced in recent decades and suggests a growing desire for gender equality.
Researchers found that male fruit flies adjust their scent sensitivity by altering a gene called fruitless in response to pheromone signals and social environment. This study may provide insights into treating sensory processing disorders like autism, as it reveals how organisms selectively tune into or block sensory input.

Researchers at the University of Göttingen investigated whether changes in a woman's menstrual cycle affect her preferences for men's behavior. The study found that women find all men slightly more attractive when fertile and perceive flirtier men as more attractive for short-term relationships, but less attractive for long-term ones. ...
Researchers at University of Kent found that men can detect the scent of axillary sweat from sexually aroused women, which increases their sexual motivation. The study suggests that chemical signals released by women can elicit a stronger overall signal that enhances human communication.

The research found that sexual desire triggers behaviors that promote emotional bonding during face-to-face encounters, including synchronization of movements, close physical proximity, and frequent eye cont...
Researchers demonstrate that fruit flies meet five criteria for culturally transmitted behavior: learned socially, copied from older individuals, memorized over time, involves individual characteristics, and conformist. Computer simulations also show the emergence of long-lasting cultural traditions through transmission chains.
About 10% of men and 7% of women reported significant levels of distress and social impairment due to compulsive sexual behavior disorder.

New research suggests women respond positively to benevolent sexist gestures due to their ability to signal a willingness to protect and provide. Despite previous assumptions that such behaviors are undermining, women still find these men more attractive, even recognizing the potential harm.
A new study published in Computers in Human Behavior found that uncertainty about a potential partner's romantic intentions decreases their sexual desirability. In contrast, feeling confident about a partner's interest and acceptance predicts higher levels of sexual desire. The research suggests that certainty serves as a gut-feeling i...
A study published in Evolutionary Psychological Science found that women prioritize practical qualities over flashy displays of wealth when evaluating potential partners. Men who conspicuously display their wealth are perceived as less committed to long-term relationships and more interested in short-term sex.
Scientists found that biological sex modifies communication between nerve cells and generates different responses in males and females to the same stimulus. This study used C. elegans to demonstrate how sex-specific configurations of neural circuits can modify behavior.

A new study by Binghamton University found that most men tend to confuse sexual interest with consent, but perceptions vary more due to situational factors. The researchers identified a precedence effect, where men equate past behavior with future consent, and the influence of rape myths on men's perceptions.
Women who experienced painful father-child relationships perceive greater mating intent in men and exhibit increased sexual arousal when viewing male faces. This study highlights the potential for early childhood experiences to shape adult mating behavior and increase the likelihood of engaging in unrestricted or risky sexual activity.
A UK study found that individuals who started viewing sexually explicit material at a younger age were more likely to engage in sexual activity at an earlier age. The research also revealed a correlation between ongoing exposure and having multiple sexual partners, particularly among women.

Kisspeptin treatment also enhanced brain activity during assessments of reward, drive, and mood in healthy heterosexual men.
Researchers at Tohoku University found that a mutant strain of fruit fly lacks the scribbler gene, rendering them unable to copulate. This impairment parallels the neural control of copulation in humans, where BMP signaling and serotonin regulation are crucial for sexual activity.
A new questionnaire developed by Cornell University researchers accurately predicts problematic behaviors such as unprotected sex and binge drinking in young adults. The Gist Scale's 12 simple questions assess an individual's ability to delay gratification, with results showing it outperforms other measures in accuracy and length.
