I'm about 2 months and 2 weeks into hrt, and my nipples have become puffy and it looks like they are slowly starting to protrude. But I'm worried at 5'9 and 105 pounds that they won't get to a good size. will I have to put on weight?

Here's how my doctor described it: HRT will produce the breast tissue, but the majority of breast size comes from fat behind the tissue. Now, depending on genetics/luck, your breast tissue alone might be enough with little fat to support it, but it will probably help to gain a bit of weight.

I weigh MUCH less than you, so the best I can possibly hope for is 32A. Even that's probably unrealistic.

Hi,

If you are 20+ by the time you start HRT it will be difficult to have any major development, the best thing may be to consider BA sometime in the future.

When did 20 become the cut off?  My chest is getting bigger by the day and I'm 32.  Granted I have much more meat on my bones... In theory, your body will signal to you it needs more material by making you hungry.  Kind of like the first puberty we went through... Mother couldn't stock the fridge fast enough for us kids

The average breast is about 2/3 fat, so you will at minimum develop actual breast tissue (as others have said) but a reasonable body fat percentage will help with padding them out - as well as enhancing butt and hips.

(I also have noticed over the years here that plenty of women who started HRT post-puberty do get fine development; many consider themselves an "exception," but if there are more exceptions than the rule, well. Personally I think we tend to get more or less what we would have if we'd gone through puberty at the right age. And I've only been grateful that I'm overweight when it came to breast development and curves; 42DDD and still growing slowly, though I think it's all extra fat as padding now.)

Yes you can still develop a good amount of breast tissue, it really just depends on your genetics though. I was like you when I started hrt, 5'10 weighing about 120 lbs sometimes less but ever since I started hrt I've been making an effort to gain weight and it seems to have worked for me. About to hit my two and half year mark and I'm now a small b (32 b), full (34 a) a cup depending on the bra manufacture. I have spanish genes and my mom has wide hips and a small bust, same goes for my sister so a lot of my fat has ended up on my hip and thigh sections. Some of it does go to my boobs but not a lot, so as always genetics are the determining factor for breast growth.

Fat will help with a little bit of size but most of the time it does not make a big difference, my mother and my sister have good chests, but in my case they were growing but not really looking that feminine.

Everybody genetics are different, but in my case BA helped a long way.

Genetics are everything. If you're naturally very thin and your mother's an A cup you're really not going to see much. On the other hand, if your hormones are in balance and your appetite is sufficient (don't over-exercise, but absolutely be active to keep your body aligned, breathing good, circulation vibey, and appetite high) then even if you're in your mid-late twenties it's still possible to develop. It's also possible to lose what you had by losing more weight, unfortunately :/

Gummy bear implants! I had ruled out augmentations as looking unnatural until I saw these last year. They more closely resemble the shape and composition of actual breast tissue and are only slightly more expensive. If I had the extra cash I would probably go for it, but being thinner than the OP I'd actually like to somehow manage to gain at least 20lbs and see if that helps at all before deciding to go for it.

20 a cutoff? Don't tell my 48 year old body that. I was minimal in growth until "P" came along. I am now a "C" cup. HRT is a strange creature that can do what you least expect. Give it time and eat sensibly. You will have to have some extra fat in your diet though. Good luck!

Haha I don't know how these age myths get started. I started at 33 and let's just say I'm not lacking in the breast department. And to answer the original post it will be hard to get bigger breast with a skinny body type. Breast tissue needs fat.

Yeah, I should have said, I started at 32. My mother is very skinny and a 34B, too. But it's clear I (and my sister) take after our busty, curvy paternal grandmother.

I don't agree with this. I've known many transwomen, some of them well into their 60s, who have gotten good development from HRT. There is no real cutoff. It depends largely on genetics and your specific HRT regimen.
