Testosterone gives transmen incontinence, bladder & bowel problems

That's terrifying and tragic. I know vaguely of one in real life. Since transitioning in her 30s she's developed serious facial adult acne and male pattern baldness. Which I thought was bad enough but the statistics about pelvic floor dysfunction resulting from these drugs is horrendous.

It's not surprising to hear the risks are being withheld from the patients since hard to countenance anyone willingly exposing themselves to this otherwise.

YouTube flagged this for me

I don't know anything about the YouTuber who posted it and he doesn't appear on the excerpt, just makes an off-screen comment at the start.

Claire is very brave. I thought she deserved to be seen more, even if it's just by a few women on MN.

It also means that, if you are presented with a single brain scan to look at, and no other information, it is not possible to identify it as male or female.

The differences are small and apparant only at a population level i.e. when taken on average, but the spread or variation overlaps hugely between the sexes.

It is not possible to use an individual's brain scan to "diagnose" being gay, or transgender, or male or female.

Can you explain what you're trying to prove here?

Male and female organs may have some differences due to chromosomes, hormones and body size. The brain is one of these organs. And?

Oh for heaven's sake.

A brain in a male body is male. A brain in a gay male body is male. No amount of similarities makes it female-like.
It's like those who count numbers of genes and tell us we are similar to frogs.

The brain is in a sexed body. This does not make it a sexed brain. Soon we will have female hearts and female livers and female eyes.
Yes we have typical differences in development but these organs are not lady organs.

More evidence for sex differences on average.

I am strongly GC and I do not want to distract or argue against the effects of T. But given I was challenged quite aggressively by someone who seemed to think acknowledging average sex differences in the brain was tantamount to sexualising children, I was entitled to defend myself.

Oh look! Squirrel!

What the heck has this got to with testosterone being harmful to women?

Humans can't change sex. Men must stay out of women's spaces.

I asked for innate

our brains develop and various parts and aspects get enhanced because of the world we live in and our experiences

transwomen and women for example also have brain similarities- the area of the brain that stores trauma responses - women and transwomen and soldiers of either sex

Scientists can reach different conclusions without being con artists, liars or pseudoscientists.

    I will reread them all tonight but I don't think they were any of those things 

Fwiw, Gina Rippon's research has been challenged.

@AliasGrace47 Those 'studies' are pseudoscience. It's just not true. It's an absolute LIE. You've been conned by lies.

Have you read the articles I cited about gay people's brains?

Until you can identify features of brains that relate to a specific sex you can’t say homosexual brains are like those of the opposite sex

what features mark out the female brain ( before any nurture induced changes have occurred )

My sister transitioned around 5 years ago and now has stage 4 cancer. Everyone insists that it isn't related to the testosterone, but it's hard not to wonder.

Really sorry to hear this - I also have a female family member who transitioned recently, plus she's very overweight and middle-aged, and I'm really worried about the health implications of the testosterone.

I think the explosion of trans-identifyng younger females should now provide a clear study cohort for the coming years and decades - though of course we do know a good deal already from the sports doping effects, and it's not good.

What UK patient protection regulator is actually stepping in right now to stop this avoidable harm to women and to rectify this medical scandal by sanctioning those providing the access or advice regarding testosterone?

I wonder if this article was what TempestTost was referring to?

https://www.theatlantic.com/health/archive/2012/12/where-masturbation-and-homosexuality-do-not-exist/265849/

I've seen a 1960s table of cultures which didn't have various things, including homosexuality. Most of them have it now, though! Was that what you meant, TempestTost?

There was actually a German scientist, for one, who claimed that boys conceived during the heavy bombing of German towns in WW2 were more likely to be gay, though tbf his research was since challenged.

One of my 18yr olds schoolfriends has already started on testosterone. She's a little thing, clearly autistic (known the family since nursery) and already got a beard. At eight-fucking-teen. Her poor body still hasn't matured. Makes me so angry for her.

Another family seem to have had a near miss and their daughter appears to be ok now and out the other side without any medical intervention.

I think there is some evidence (from the sources upthread) that the brains of homosexual individuals tend to be more than averagely like those of the opposite sex, which, ironically, has confounded some research aimed at proving that transgender people's brains are 'wired that way'.

But it's just a population-level trend. You can't tell from a brain (scan) what sex someone is, because the characteristic being observed isn't bimodal.

Bimodal characteristics are things like possession of ovaries, grip strength, neck circumference, and endogenous T levels. With only one of these pieces of information, you could predict the person's sex with a high degree of confidence.

I don't understand @TempestTost's statement that there are cultures with pretty much zero incidence of homosexual behaviour, to the point it isn't even a taboo.

So by your reckoning any child born to mothers who have been through a traumatic pregnancy has a higher incidence of a child who is lesbian, gay or trans. Should be easy to check, there are enough conflicts in the world, and have been for many years, so tracing and identifying children born in those conflicts should give a pretty good indication of whether that theory stands up to scrutiny.

From your first link.

All these measured differences are averages derived from pooling widely varying individual results. While statistically significant, the differences tend not to be gigantic. They are most noticeable at the extremes of a bell curve, rather than in the middle, where most people cluster. Some argue that we may safely ignore them.

Small differences, mainly at the extremes. This doesn't mean that they're not important in some circumstances, but in everyday situations they're irrelevant.

Since the Fife evidence I am not surprised at any strange beliefs and misinformation many medical professionals hold.

men are women.

you can’t tell a persons sex without checking their dna.

no one can tell if a man is a TIM or simply a very tall woman with receding hair , a deep voice , a history of accusing people of transphobia and of intruding into women only spaces.

It’s obvious that men’s and women’s brains are different, just as other organs are different, because they exist in (binary) sexed bodies.
I’m willing to believe that some innate differences in female and male behaviour are the result of evolutionary pressures. To me, it would seem odd if this were not the case.
But to say that homosexual or effeminate men have brains more like women, and vice versa, seems like wishful thinking.
