Study: Last News

Journal of Sex Research last week affirmed the longstanding theories of a “fraternal birth order effect,” in which “men’s propensity for homosexuality increases with the number of older biological brothers they have,” the researchers noted in an article for The Conversation.The scientists — Christine Ablaza, Francisco Perales, and Jan Kabatek — noted that past research into fraternal birth order effect had involved small samples. To counter this, researchers used Dutch population registers and followed the lives of nine million people born between 1940 and 1990.While the registers don’t explicitly state sexual orientation, researchers used same-sex partnerships and same-sex marriages to determine an individual’s sexuality.They argue that, despite excluding all gay people who haven’t registered an official partnership or marriage, their findings demonstrate “clear evidence” of fraternal birth order effect on homosexuality.Dutch men with three older brothers are 41% more likely to be in a same-sex relationship than men with three older sisters.They are also 80% more likely to be in a same-sex relationship than men with three younger brothers, which researchers say show that being the youngest sibling increases the likelihood of homosexuality — and that the differences increase with the number of older male siblings.However, even one older brother can make a difference.

report, released last month, provides an estimate of the number and percent of the U.S. LGBTQ adult population, based on data from the Behavioral Risk Factor Surveillance System, a network of health-related telephone surveys that inquire about Americans’ health-related risk behaviors, chronic health conditions, and use of preventive services.Based on the BRFSS data, the Williams Institute estimates that approximately 5.6% of the U.S.

Plos One medical journal — gay and bisexual men over 70 were more likely than their straight peers of the same age to have had more than one sexual partner recently.Those men were likely to continue having sex with multiple partners, while straight men and women became less sexually active.Women who have sex with women, and other relationship types, were discounted due to small sample sizes.The study, conducted by researchers at the University of East Anglia, King’s College London, and University College London surveyed more than 5,000 adults during the 2022 mpox outbreak, looking at how sexual activity changes with age, in order to develop scientific models for sexually transmitted infections, reports Sky News. Researchers surveyed 5,126 British adults from September to October 2022 — including 3,297 from the general population, 1,036 men who have sex with men recruited from Facebook and Instagram, and 831 people responding to adverts on the gay dating app Grindr.“Before this study, many models about sexually transmitted diseases assumed that everyone over a certain age, say 40 or 65, stopped being sexually active, or at least stopped having multiple partners.

Journal of Adolescent Health finds that transgender youth who receive gender-affirming hormone therapy have lower rates of depression, suicidal thoughts, and suicide attempts than their other trans and nonbinary peers who have not received hormones.The article, “Association of Gender-Affirming Hormone Therapy with Depression, Thoughts of Suicide, and Attempted Suicide among Transgender and Nonbinary Youth,” is being hailed as the first large-scale study examining transgender youth receiving hormone therapy, based on a sample of more than 9,000 trans or nonbinary youth.Researchers at the LGBTQ youth suicide prevention organization The Trevor Project, who conducted the study, found that only 14% of trans-identifying youth were receiving

any publicly-funded entities, facilities, or events, which would include college and club sports. Meanwhile, the Senate version had sought to commission a study on the issue of transgender participation in sports. Ultimately, the bill that emerged and was passed by both chambers included a scaled-back ban on transgender athletes in K-12 sports and an optional study of the impact of the bill on student athletic events, with findings being reported back to the 2023 legislature.As approved this week, the bill prohibits public schools from “knowingly” allowing a student assigned male at birth to participate in female sports.

A recent study from the Williams Institute has highlighted the heightened impact of the COVID-19 pandemic on LGBTQ people of color, as compared to heterosexual white people. The Williams Institute, a UCLA School of Law think tank, collected data from 12,000 U.S.

introduced in 2015 under the Obama administration, there was a categorical ban on any man who had engaged in sex with another man since 1977. That restriction was introduced in 1983 in response to the HIV/AIDS crisis and the inability of technology to screen blood for the virus.

Movement Advancement Project report found that, compared with non-LGBTQ households, LGBTQ households are twice as likely to be unable to get necessary medical care and four times more likely to not have enough food to eat.Among MAP’s other findings, LGBTQ households experienced higher rates of serious financial problems, job losses, issues accessing health care, and greater challenges with regards at-home learning for children as a result of the pandemic.“The pandemic has disrupted life for all of us.

study, “School Outcomes of Children Raised by Same-Sex Parents,” published in the American Sociological Review.Researchers examined children raised by 3,000 same-sex parents — 2,786 female couples and 185 male couples — and those raised by more than one million opposite-sex parents.The study was conducted in the Netherlands, which became the first country to legalize same-sex marriage in 2001.The results show that children of same-sex parents outperform their peers at all levels of schooling, from elementary through high school.

A disturbing study has found that one in five Russians advocate for ‘eliminating’ LGBTQ people.

the study, published in the journal Annals of Internal Medicine, are that potential sex partners should avoid kissing, wear face masks, and stay away from any acts “with a risk for fecal-oral transmission or that involve semen or urine.”Researchers outlined a number of sexual approaches and their relative risks, as well as steps to reduce those risks.
