A study found that sexually experienced girls resume sexual activity after periods of abstinence, with short-term factors including good relationships, personal interest, and mood influencing the decision. Long-term predictors include relationship quality and personal interest.
A randomized controlled trial found that an abstinence-only program targeting reduced sexual intercourse was associated with lower rates of sexual involvement among African American sixth- and seventh-graders. After 24 months, 33.5% of participants in the abstinence-only group had engaged in sex, compared to 48.5% in the control group.
A new study by the University of Pennsylvania shows that an abstinence-only intervention for pre-teens can delay the onset of sexual activity. The program reduced self-reported sexual intercourse by 33% compared to a control group, with fewer reports of recent sexual activity among participants.
Researchers found that emotionally mature students experience positive benefits from sex, while immature students face negative emotions. The study highlights the importance of considering individual readiness and motivations before engaging in sexual activity.
Researchers at Tufts University discovered that maternal behavior can stimulate new neuron creation in the brains of adult female rats who have never given birth. The study found increased numbers of new neurons in the subventricular region of the brain in these rats, which exhibited maternal behavior when exposed to foster pups.
A study by Duke University researchers discovered a commonality in the genetic codes of human sex receptors and those found in other primates. This similarity suggests that varying sensitivity to specific odors may play a role in mate selection, potentially preventing cross-species couplings.
Studies across various species reveal that males tend to exhibit more predictable behavior, particularly in parental care, aggression, and risk-taking. Females, on the other hand, are more likely to vary their behavior and respond to these traits, indicating a preference for mates with consistent personalities.
A new study by Queen Mary University of London reveals that young men living at home with their parents are more violent than those who live independently. These men, making up only 4% of the UK's male population, are responsible for 16% of all violent injuries in the last five years.
A two-year grant from NIMH will support the adaptation and assessment of an HIV intervention designed for young, heterosexual Latino couples. The program aims to increase condom use, monogamous relationships, and decrease risky sexual behaviors.
A new longitudinal study reveals that fathers respond to their children's risky sexual behavior by increasing supervision and monitoring. Teens who engage in risky sexual activity are more likely to have involved fathers, who show a greater interest in their children's lives.
A new study from U of T's Rotman School found that employees who experienced sexual behavior in the workplace reported lower morale, felt less valued, and had higher rates of depression. While some employees enjoyed such behavior, its presence was often counterproductive.
Research reveals marked gender and race differences in children's moral behaviors, both in the real and virtual worlds. African American children were more likely to view morally questionable virtual behaviors as acceptable when they benefited individual goals.

Public concerns about costs and promiscuity pose a barrier to cervical cancer vaccinations, according to a Yale University study. The vast majority of surveyed adults believe the risk of cervical cancer is low with the HPV vaccine, but think adolescent promiscuity will increase among vaccinated teens.
A study by University of Toronto sociologist Adam Isaiah Green found that gay men deemed less desirable are more likely to engage in risky behavior and experience psychological problems. The research highlights the negative consequences of being marginalized due to low levels of 'erotic capital',
Researchers found that boys who experienced childhood physical or sexual abuse were more likely to use sexually coercive behavior against an unwilling female partner. Men who experienced both types of abuse were 4.5 times more likely to engage in such behavior.
A study in the Journal of Communication found that TV portrayals of risky sexual behavior can increase expectations of future engagement among inexperienced viewers. In contrast, those with direct experience are not influenced by TV content. This research highlights the potential for media to shape attitudes and behaviors.
Abstinence-only programs are found to be inaccurate, ineffective in changing sexual behavior, and violate human rights principles. Studies show that these programs withhold life-saving information from young people and conflict with ethical standards.
A new study finds that binge drinking among women attending an urban STD clinic is linked to high rates of gonorrhea, anal sex, and multiple sex partners. Women binge drinkers are five times more likely to have gonorrhea than non-drinking women.
A new University of Washington study reveals that abstinence-only programs do not effectively prevent teenage sexual activity because they fail to speak the same language as adolescents. The research found that attitudes and intentions about sex were more powerful than those about abstinence, leading to increased instances of teen sex.
Researchers found that bold birds, who sing from exposed sites, are more likely to be explorers and risk-takers in the wild. These individuals have a higher mating success due to their attractiveness to females.
A study of over 7,600 Swedish twins found that genetic factors and the individual's unique environment play a significant role in determining their choice of sexual partner. The results suggest that familial and public attitudes have a minimal impact on this decision.
A study found that frequent self-cutting is linked to higher rates of HIV risk among teens. Teens who frequently cut themselves were more likely to share cutting instruments and exhibit less self-restraint.
According to a University of Washington study, teenagers attending college are significantly less likely to engage in risky sexual behavior than those who do not attend college. The study found that college students were more likely to always use a condom and less likely to engage in casual sex or high-risk sex.
Women in Botswana and Swaziland who lack food are more likely to sell sex or engage in other risky behaviors. Nearly one in three reported food insufficiency, which increased the likelihood of inconsistent condom use and intergenerational relationships.
Research finds that women in Botswana and Swaziland who experience food insufficiency are nearly twice as likely to have high-risk sex. Protecting access to food may decrease vulnerability to HIV infection, says a new study published in PLoS Medicine.
A new study reveals that a single gene, OR7D4, plays a crucial role in determining how people perceive the scent of androstenone, a potent ingredient in male body odor. Variants of this gene can make humans perceive androstenone as sweet or unpleasant, with some unable to detect it at all.
Research suggests that a sensory organ in the noses of mammals differentiates male and female behavior, rather than the brain. Female mice with mutant vomeronasal organs adopt male behaviors like mounting and pelvic thrusting, abandoning maternal actions.
Researchers at Howard Hughes Medical Institute disabled a sensory organ in female mice, prompting them to exhibit male-like behaviors during courtship. The findings suggest that the neural circuits governing gender-specific behaviors are similar in both sexes.
A researcher at Arizona State University has created a 3D computational model to simulate crowd behavior in urban settings. The model takes into account individual characteristics and environmental factors, allowing city planners and public safety officials to explore 'what-if' scenarios and test hypotheses.
A new study reveals that a simple and brief screening measure can quickly identify the broad range of risk behaviors found among adolescents. The adolescent risk inventory (ARI) identifies behavior problems that may prevent teens from engaging in other risky behaviors.
A new approach to HIV prevention focuses on reducing partners, with early evidence from Uganda and Kenya showing a decline in HIV incidence among men. The strategy is seen as a crucial step towards reversing the epidemic, particularly in regions where partner reduction has been successful.
The study found that monogamy is the dominant pattern globally, but multiple partnerships are more common in industrialized countries. Rates of condom use vary widely by country and region, with increasing trends in some areas.
A review of global studies reveals that young people's sexual behavior is influenced by stereotypes about men and women's roles, leading to inadequate condom use. Social expectations, such as feeling pressure to have sex or worrying about one's reputation, can significantly hinder the effectiveness of safer sex campaigns.
The first global analysis of sexual behavior data found that monogamy is the dominant pattern worldwide, and developed nations report high rates of multiple partnerships. Despite this, adolescents have high rates of unintended pregnancy, unsafe abortions, and STIs.
A study published in PLOS Medicine found a strong association between heavy alcohol consumption and high-risk sexual behaviors in men and women in Botswana. The research highlights the need to address alcohol abuse within HIV prevention programs, considering cultural and social significance of alcohol use.
Researchers found that a command hormone called ecdysis-triggering hormone (ETH) orchestrates activities in discrete groups of peptide neurons in the brain, initiating innate behaviors such as escape and defensive maneuvers. This discovery could lead to manipulation of behavior in animals and intelligent robots.
A study found that 40.9% of teenage girls reported unwanted sex at least once, with 37.6% fearing their partner's anger if denied sex. The data highlights the need for sexual health counseling to reduce risk and promote healthy relationships.
A study of 93 women at Ohio State University Medical Center found no correlation between the frequency of sexual intercourse and the onset of labor. Women who were sexually active during the final weeks of their pregnancies carried their babies an average of 39.9 weeks, compared to 39.3 weeks among those who abstained from sex.
Researchers found correlations between DNA variants in the D4 receptor gene and self-reported sexual desire, arousal, and function. Variants affecting dopamine levels were shown to influence sexual behavior.
A global study of over 27,500 adults aged 40-80 found that greater gender equality leads to improved sexual satisfaction. The research, led by the University of Chicago, compared sex lives across 29 countries and discovered that countries with more equal partnerships reported higher rates of sexual pleasure.
The study critiques government policies promoting abstinence-only programs, arguing they provide misinformation and neglect real health needs. It advocates for comprehensive reproductive health promotion programs that include information on contraceptives and STI testing.
A study of young girls referred to pediatric clinics due to alleged movement disorders found that most cases were actually normal muscle contractions during masturbation. Children can be easily distracted from these episodes, and parents should not assume harm or deviancy from the behavior.
A study found that living in close-knit neighborhoods with strong adult supervision can delay early sexual experiences among teens. The results suggest that good neighbor relations play a crucial role in preventing risky behavior, especially for those with limited parental supervision.
Scientists used a genetically altered virus to trace connections between olfactory neurons and LHRH-producing neurons in mice. They found that the main olfactory epithelium sends signals to LHRH neurons, controlling puberty, ovulation, and testosterone production. The study challenges traditional views on pheromone communication systems.
A study found that an abstinence-only sex education program increased teens' knowledge of HIV/STDs and their commitment to abstinence. However, it had mixed effects on sexual behavior, with no impact on the likelihood of having sex or using condoms. The program may reduce casual sex encounters among sexually active students.
Researchers found that male mounting, even without semen transfer, reduces a hen's tendency to mate with other males and decreases the number of sperm obtained from a new rooster. This behavior helps defend paternity, suggesting copulations without semen transfer have evolutionary significance.
Researchers have discovered a single gene, fruitless, that determines how females and males detect and respond differently to sexual cues. Activating this gene in female flies produces male-like courtship behaviors, challenging the assumption that males and females perceive the world similarly.
Researchers found that stimulation of the posterior parietal cortex elicits complex, innate behaviors such as aggressive facial patterns and hand-to-mouth movements in primates. This discovery suggests that these behaviors are built-in to primate brains, including humans.
Researchers found that increasing one skill can significantly impact others, with some activities dropping and others increasing in levels. The primary function of the enzymes remained largely unchanged despite changes in other promiscuous traits.
Research suggests that impulsive behavior in animals, including blue jays, may be an evolutionary adaptation to foraging in the wild. The study found that birds prioritized immediate rewards over delayed ones, as they would often forget about food and continue foraging. This impulsiveness may have been beneficial for survival but is no...
Researchers discovered a cluster of 60 nerve cells choreographing the courtship ritual in male flies. Interfering with these cells resulted in reproductive failure and abnormal behaviors, supporting the idea that basic circuitry mediates attraction and mating across species.
Germany's restrictive laws on human reproduction have roots in the Nazi era, where doctors and scientists were motivated by racial ideology and conformity. Understanding this history is crucial for making informed decisions about reproductive medicine today.
A recent study found that male and female brains react uniquely to sexual cues, with males showing higher activation in the amygdala. This discovery may have implications for understanding human behavior and developing treatments for sexual dysfunctions.
Researchers at Duke University have discovered a fruit fly pheromone receptor that plays a crucial role in courtship and mating. The study found that male flies lacking this receptor struggle to recognize females and initiate successful matings.
A new study by Ohio State University researchers found that some reported gender differences in sexual behavior might be due to women being less than honest when surveyed. Women's answers were closer to men's in certain areas of sexual behavior when they thought lies could be detected, while men's answers didn't change as much.
A study by Margaret A. Chesney found that noninjection drug use and unprotected receptive anal sex were the most likely predictors of risky sexual behavior among gay men, accounting for only one-third of cases. One-on-one counseling tailored to individual behaviors may be effective in preventing new HIV infections.
Researchers have identified a group of cells in the spinal cord that control ejaculation, which can be manipulated to treat sexual dysfunction. The discovery has implications for paraplegic men and those experiencing ejaculatory problems.
