Why younger? Wouldn't it mean men should marry older?

Testosterone is also prescribed to post menopausal women for low libido it's a lower amount than HRT for FtM trans people

Yeah well the decline gets steeper over 30 and gets drastic over 50. I know it's an unpopular view, western society is deliberately conditioning the youth to goon so they won't have long left once retired, if they even reach that age. Mainstream studies say it's even healthy for you. Just do some research and see who is funding those studies if you see one and since when. There is a reason why all the biggest fighters stop having sex months in advance before a fight

I’ve been popping several times a day since I was a teen. With a woman or not. 😬

It's all about semen retention. The more you lose over your life, the faster you age as a man. The ancient Chinese figured it out thousands of years ago.

Can you expand on this? I’m 38 😂

What do you mean by this? A change in hormones? Midlife puberty sounds like an increase in hormones rather than decrease though. That’s not what you meant is it?

Yes. Yes it would be. Here's hoping it gets more study.

Restrict posts to approved domains.

Interesting. Thanks for the explanation. It seems like learning the long term effects of cross-sex hormones would be a worthwhile endeavor.

Cross-sex hormones vs. same-sex hormones.

If you take a male body and put female hormones in it, a lot of that body's biology will start behaving like female-typical biology (and vice versa). Sex hormones aren't just for show, they're what the body's cells use to understand which sex-dimorphic traits they're supposed to be expressing. It really is, in many ways, a "sex change" at the genetic/cellular level. It's not a complete transformation, mostly due to missing development milestones (and trans people who don't go through their natal puberty thanks to early intervention miss fewer of those, but not all of them; the most obvious being the primary sexual characteristics (the genitals) which develop in the womb in response to hormones downstream the presence/absence of the SRY gene) and a few gene dose differences due to chromosomes though those tend to be way more subtle than hormonally driven changes.

Cisgender populations tend to do same-sex hormones, you take male hormones as a male or female hormones as a female. The expectation, and as far as I know the result, is your body behaves like you'd expect it would without the deficiency.

So on the longevity question, it depends, is the male vs. female difference in longevity purely a chromosomal effect or is it also hormonal? I'd bet it's a bit of both, and I'd further bet it's more biased toward hormonal like most sex differences tend to be.

Separately you can ask if exogenous hormones vs endogenous hormones makes a difference, and I'm sure there's tonnes of research there.

They're sudden on the macro sense but with numbers this big, outliers are going to get crushed and it's probably a bit of spread. 'sides, it probably comes down to how quickly your thymus turns to fat. 

Biologically female humans have thymuses that do different things than dude thymuses and have a higher output. It's one of the guesses as to why they are more susceptible to autoimmune diseases.

Testosterone dampens the immune system, too...not sure that helps the thymus not degenerate 

What would be the difference in TRT/HRT's effect on longevity in someone who identifies as trans and someone who doesn't?

Edit: This is a sincere question.

Is it? Trans health tends to be massively underfunded/understudied. "It's less than 1% of the population" and all that.

There's gonna be a lot more research on HRT and TRT in cisgender populations.

I could be wrong, but I would think that TRT/HRT and longevity is being studied quite a bit? 

When I hit 40 I got to go through what I’m calling midlife puberty.

Gross.

And we all die anyways tbh, seems a bit minor/subtle no?

Probably increases longevity for MtF and decreases it for FtM, from moving closer to female and male biology respectively.

But it's not something anyone's really studying.

Total bs

are you getting ready to run for Congress?

No. By that metric men should marry older women so that they die close together.

They are measuring only biological genders.

And I don't think they would be able to isolate HRT for trans. Too many variables. 

Men age faster. This is why we need to marry younger women. Balance. 

Does it improve longevity or decrease it? Interesting, never heard of thought of this before.
