#sex differences

Little boys can't learn the same way little girls learn at a very young age, and we're over diagnosing little boys with behavioral problems and ADHD, and a lot of that has to do with forcing them into situations that are not good for them.

Meaning, little boys have a lot of testosterone between the ages of three and six, which means they need to run around a lot and between learning, they need to have a lot of physical activity and we're making them sit in circle time and we're restraining them in a way that's causing them to feel a great deal of stress with very high levels of cortisol, which makes them seem distractable. And then they're diagnosed as being problems in the classroom.

And we're really failing little boys. It's not that there's something wrong with them, there's something wrong with the way we teach them.

School is structured for girls (and female teachers, who are ~85% of teachers), not for both sexes.

Driving Testes

Testes, the male reproductive organs, comprise many cell types. This research focuses on the male hormone-producing Leydig cells in foetal testes and finds that Nr2f2 gene regulation is crucial in their development

it's not a bad question! i have mixed feelings; i don't really consider it intersex. since i define intersexness as someone who (by natural circumstance) has differences in sex chromosomes, sex hormones, or physical sex traits, leading them not to fit into the sex binary.

so i'd consider PMDD as a reproductive condition, not a sex variation. however, all people with reproductive differences are united in our fight against oppression - intersexism, sexism, and ableism often occur alongside each other. also, many intersex people have reproductive disabilities.

The website SheWon.org is asking for public input as it compiles a list of all female athletes who lost records, titles, medals, or scholarships to biological males.

"This website is dedicated to archiving the achievements of female athletes who were displaced by males in women’s sporting events and other types of competitions expressly for women. One day soon we hope their accomplishments will be formally recognized," explains the website's home page.

So far, SheWon.org lists 764 female athletes who gave up 1,086 medals in 528 competitions in 40 sports since 2019.

The United States of America dominates the list. However, Australia, Belgium, Brazil, Bulgaria, China, Colombia, Czech Republic, England, Estonia, Ethiopia, Finland, France, Germany, Iceland, India, Ireland, Italy, Mexico, Nauru, New Zealand, Netherlands, Norway, Poland, Samoa, Scotland, Spain, Switzerland, Turkey, United Kingdom, Uzbekistan, and Wales, are also represented.

Katia Bissonnette is the most recent Canadian on the list. An hour before she was to box in the Provincial Golden Glove Championship in Victoriaville, Quebec, she discovered her opponent was the male-born Mya Walmsley. Bisonnette bowed out, citing safety reasons.

A 2020 University of Utah study found a male punch has 163% more impact than a woman's, even when adjusted for weight. Nine boxers were on the SheWon.org list.

Among sports, 347 female track athletes led as those most frequently affected, followed by 266 in cycling, 171 in disc golf, 72 in mountain biking, 39 in swimming, 29 in power lifting, and 20 in cross-country running. The athletes lost 351 gold medals, 317 silver medals, and 303 bronze medals.

A partial list of "men and boys who have competed in women's or girls' sports" numbers 344 in 61 sports. A link is included for each person on the list.

The site includes a list of female athletes who have openly identified as men and won medals in men's or open competitions. The total seems to be zero as the entry says "No data found."

The website includes a submission page where visitors can submit additions to the list.

I never thought about the “de-sexing any behavior opens it up to colonization” aspect but yeah; I agree. Also - I have a maybe unpopular take that feminists should be careful with saying what is and isn’t a social construct or learned behavior when it comes to differences between men and women.
