#klinefelter syndrome

[river-taxbird]

Normally, Calico cats should only be female, however one in three thousand Calico cats are actually male. This is because they have Klinefelter Syndrome, an intersex genetic condition. In cats, colour is stored on the x chromosome, a three coloured Calico has to have 2 X chromosomes, plus white. Males usually only have one X, unless they have Klinefelter Syndrome, where you have two X's and one Y.

Furries are quick to point out that male Calico cat fursonas wouldn't exist, but they actually would, they'd just be rare. Klinefelter Syndrome also occurs in humans of course. (I know this first hand.)

Therefore I propose: Calico Catboys COULD be real, despite what the furry meme says, however if they followed the human characteristics of Klinefelter Syndrome, they would be taller than average, usually over 6 feet, have a feminine weight distribution, including some limited breast growth, have a feminine hair/fur growth pattern, and have around a 20% chance of being autistic.

Thank you for coming to my TED talk.

4 Ways a Male Cat Can Be Tricolor

The X chromosome in cats determine their fur color. This gene has two alleles, one for orange fur (XB) and one for black fur (Xb). Females carry two X's and males carry one X, allowing female cats to have two colors while restricting male cats to one. Therefore, it is extremely rare for calico males to exist!

Klinefelter Syndrome (XXY)

Male cats with an extra chromosome (X)

Allows for the expression of both orange and black pigments

Infertile

Extra X chromosome interferes with sperm production

Chimerism

Two embryos fuse together early in development, leading to a single individual with cells from both embryos

Allows for tricolor pattern in males

Sometimes fertile (depends on if the combination affected the reproductive organs)

Only one of their colors will be passed on to offspring

Mosaicism

Individual cat has two or more genetically different types of cells within their body

XXY cells and XY cells found in the body

Sometimes fertile

Only one of their colors will be passed on to offspring

Birthmark

Might be a patch of a different color or shade on the skin or fur

Does not result in a true tricolor pattern, but still causes variations in fur color

Fertile

Birthmark color does not affect offspring color

Hello! So recently in my biology class we discussed certain genetic disorders, including those that affect sex. Some of these disorders and syndromes include Jacob’s Syndrome (XYY), Klinefelter Syndrome (XXY), and Turner Syndrome (X).

I mean this in the most genuine way possible, and I’m sorry for any naivety or insensitivity, but would these be considered types of intersexuality? I asked my teacher but I don’t think they heard me, and I’ve been wondering about it. I didn’t want to look it up for fear of misinformation, so I was hoping I could get some insight from an intersex person rather than the internet 😅 thank you for your time!

as far as i'm aware of, all 3 of those are intersex variations, but it's been a while since i've read up on them. if i'm wrong please correct me, but i feel like i remember reading that all 3 of them are intersex variations!

Small Question from a Perisex Writer!

Hi! This is kind of a specific question, but I'm writing a series with a protagonist with Klinefelter's. It's not the central part of his character, and I'm trying not to delve into aspects of intersexual identity that I'm just plain unqualified to claim authority in. He's just an intersex guy facing cosmic horrors and trying to get better.

But also he's one half of a romantic pairing, and in the next book of my series their relationship gains a sort of level comfort. Up until now he's been pretty malnourished and sick, but in this book he's gained weight and essentially fully recovered. He's got a bit of a tummy and he's a happy dude before the next part of the plot happens. And so I would love to know what members of the intersex community would love to see romanticized in a stable relationship involving an intersex person.

They're both ace (pretty much all of the main cast is) and the guy specifically is sex-repulsed (but with a high sensual attraction). He presents in a way some would consider femme, with flowy dresses and long hair, but he's also pretty feral and usually barefoot and wild-eyed. The dresses are more of a sensory thing for him. I've done a lot of research into Klinefelter's, mainly the health issues that might come out of it, but also the general body type seen in the variation. But like I'm definitely not looking to exploit any of my character's bodies just for the novelty of it. That's trash.

But yeah any help or insight would be really appreciated! As I said, the story isn't about him being intersex, but I'd still really value creating a nurturing love that intersex people can enjoy.

This is the most extensive Transition Timeline I have created.

[klinefelterrible]

I should be a trans girl but since I have klinefelter’s I think I should troll hard the right wingers and tell them I am a trans man so they could be trying to defend their position that I am, I was and will always be a girl so they will fucking flip the logic outside the garden and into a wormhole in my ass, while I will be living officially as a former girl and now man but transphobes will do gods work and do the exact opposite of what they should be doing

And I’m 1,9m tall so they’ll fucking walk around me and try to figure it out and if they want to attack me so using their logic they shouldn’t attack a girl, right? Right?

I think when they learn I’m a XXY they will literally shoot me for being a freak but who cares now I don’t

New headcannon 4 Mr plant!!!

He’s has Klinefelter syndrome (or just XXY chromosomes) due to being partially plant and i think that would fuck up his chromosomes,, at least a little bit..

He was pretty insecure growing up since he knew something was.. different in his body. When his uhm, chest started growing a bit he started to get concerned, but he chose to wear high compression sports bras (that didn't work), bind them with bandages (also didn't work that well, it hurt a lot) and to get jacked to hide it, but, that didn’t work as well as he wanted it to. Argos, is probably into Mr plant’s man titties

I googled a bunch, and some people say that Klinefelter syndrome is not in the intersex spectrum, but i say Mr plant is in the spectrum ..

In 2021, at Suontaka Vesitorninmäki, Hattula, in Finland, archaeologists discovered the grave of a Viking warrior, the body wearing female clothes, on a soft feather blanket with trinkets, and two swords. They believe that the person had Klinefelter syndrome, giving rise to XXY chromosomes. This had probably been a person respected in their eleventh-century society, wearing women's clothing, fighting as a warrior, perhaps understood to be one of the many sexes on the huge spectrum of sexual identity that was then known but which we have tried to forget.

This is my alien baby Sills Royce!!

His pronouns are he/him — he's intersex n omniromantic (as well as transmasc n nebularomantic/sexual)

He has Klinefelter Syndrome (I'm always doin tons of research bout that so I don't get anythin wrong or spread harmful misinformation lol — always happy t' learn more from folks who have it haha)

He's such a goober. I love him <3

[ashes2caches]

is someone gonna tell him?

I have a question what’s the difference between PAIS symptoms and Klinefelter Syndrome

Cause I am intersex and I know it sounds like it’s faking I am not, but I have feminine curves,slight breasts, low testosterone, no Adams apple and no facial hair growth and less body hair and I was assigned male at birth

super late on this but i dont know too much about PAIS or KS. i mean they come about differently, PAIS is due to androgen insensitivity whereas KS is from having XXY chromosomes.

edit; my info was wrong but this glossary may be helpful, especially if there's something else that may fit your presentation other than KS and PAIS.

are you on any HRT?

i'm asking because i'm also intersex (klinefelter syndrome/XXY sex chromosomes to be specific), recently got diagnosed & was wondering if i can live a healthy life without taking any hormones, or if i should start taking them for my health.

unfortunately, doctors in my country aren't really trained to learn much about intersex conditions other than the basics, so they weren't of much help.

Hello!

I am, yes. I’m on E and wouldn’t get a period without it. My body would go into a menopausal state if I didn’t take it.

In your case personally though, I’m not that knowledgable about Klinefelter syndrome and am unsure about whether you would need it. Have they by any chance looked into your hormone levels?

Meanwhile in Canada...

It would be really helpful if just one person in the media asked Poilievre to define "biological male".

I'm betting he doesn't have a definition that takes into consideration people with androgen insensitivity syndrome (XY genotype, often female phenotype and AFAB) or Klinefelter syndrome (XXY genotype, variable phenotype and assigned-at-birth gender) or trans men.

It's very revealing that all the pundits are saying his messaging on inflation / cost of living / economic issues are why he's doing well in the polls... yet he still decides this is the battle he wants to pick.

(For non-Canadians: Poilievre is the leader of the opposition federal Conservative Party. If current polling holds true, he will be Canada's next Prime Minister with a majority government).
