I start HRT soon, less than a month, and one of the more exciting things for me is of course ushering the girls in.

However, if the cisgender women in my family are any indication I'm going to get much more than I bargained for.  Both of my biological sisters have large breasts (C and D resectively) and my mother had large breasts before she lost them to breast cancer.

I want a solid B and no more.  I think I'd look awfully silly with D's flopping around on a 5'5 frame (I'm shorter and smaller than all of the cisgendered females in my family). >.<

My question is, does genetics play a part and how much?  Should I be worried about them becoming too large?

I don't know how much a part they play but . I'm 4 months in and the breast fairy has been very kind. I have a sister with large breasts and a sister with smaller ones.

I've got quite a bit more than either of my two sisters.  I'm hypogonadic and have had low testosterone for years.

Well, two months in, and I am just about an A. From what I understand, this is fast. My mother and cousin are both DD, so I am guessing this will be my uppermost limit, with a B or C being much more likely as I simply do not gain weight. Even now, I am only about seven pounds hevier, and I blame that on winter binging.

From what I gather, though, it is a total crap shoot. Plus, the only real way to stop growth would be to stop taking E. So weigh your options carefully.

Yes, genetics play a major role, as it plays with any cis-girl. For what I have heard, your breasts will normally end a size smaller than if you were biologicaly born as a female. If you have sisters/close parents with big breasts, probably your size will be close/one size smaller than their size.

I will probably end with big breasts (I hope so ^^)

My mother has huge breasts as does my daughter (and she didn't get them from my wife, whose are small). So one would expect that I would have a genetic disposition for large ones.

But I got about 3 weeks of breast growth total which hasn't quiet brought me up to an A-cup. Haven't had a millimeter of growth in the 9 months since then.

Hey there,

I was wondering myself how much diet could help. Suzi did you gain weight during the process? It seems to me that this growth is heavily not only by the quality of your food (obviously, duh) but also the total weight you take, to grow I guess you'd need to take some extra weight...? Hopefully it helps ?

No, I did not gain much weight, which might explain it. I'm pretty thin (and like it that way), though I have a healthy diet.

My sub-a-cups are not a major source of dysphoria. They're still breasts and they're mine and natural. I would rather small breasts than belly fat (which is where mine would tend to go).

It's still something of a lottery - you'll find small-breasted trans women in big-breasted families, and very much vice versa too. One important thing to bear in mind when comparing your potential/actual breasts to those of family members is to compare them to their breasts when they were in their twenties, and certainly before they had any kids. Because we're getting teenboobs, and it takes time for them to grow up.

Something my gender doc (I'm in the UK) told me is that a lot of trans women who have genital surgery find their breasts grow again after that - like the body shrugs and says "Okay, now I see what you're doing here, let me help..." - which is why they like people to be on hormones for 3 years before considering enhancement, as most people who opt for surgery do so after 2 years here. So they want to wait and see where your breast size ends up after that.

I've lost tons of weight and can't seem to get above 125 lbs. no matter how much I eat and I eat good food, not junk food. I'm a a 32D. I had a jump start however and before HRT was a 36B.

Personally, based on my own experience and a few years of observation of all my trans friends... I think genetics is almost all of it. Sorry.

The catch, of course, is that you don't know *where* the genes came from. My mother is 34B and her sister/my aunt is around the same. My sister is 36D, and my aunt on my father's side is large-breasted (don't know her actual size). I clearly have the big-boned curvy body build from dad's side - and so far I'm 42DDD, so I'm guessing the boob genes came with it. I know quite a few cis women who also ended up with surprises from the boob fairy, in either direction, compared to their mothers and sisters.

People make a good point about being patient, too. I'm 4 years on HRT this month, and still growing.

I have been on a low dose of HRT for about 4.5 years and have been on a transitioning dose of HRT for a little under 5 months now with one round of progesterone under my belt. I am a solid A cup at the moment. When I went on full strength HRT they changed a lot; they were kind of tubular, but they rounded out and filled in and hopefully now will start to grow outward. My nipples became a lot more like female nipples too, the areolas got a bit larger.

Both of my grandmothers and my mother's sister were stocky, short stout women with large breasts. My mom was the odd one in the bunch; she was tall and small breasted. I am also short and tend toward a stocky build so hopefully I got the boob gene from my grandmothers and not from my mom. I guess that I'll take whatever mother nature decides to give to me.

Hmm well nice exemple, though I guess all that food had to go somewhere :p. ANd that was quite the jump start!

My mother has D cup breasts and so do I..

I actually wear a bigger bra than she does.. she wears a 34D and I wear a 36D.. I am slightly bigger built than she is.. so that explains the band size being bigger.

My whole family are big breasted.. so I inherited these genetics.

I love my breasts, I love wearing tops and dresses that show off my cleavage.. 

yea, I finding out they are so nice to have

Not even three years in I have D's (though my ribcage makes them look more like c's).  I have both my sisters and my mom beat.

I have no idea what part of the genetic stew I'm going to inherit. My sister has no really noticeable breasts, my mother was an ample D, and my niece is a DD. 10 months on HRT, and I'm a nice full B cup. I need more for my larger frame (38 band size), but who knows where it will end given my genetics.

>.< I'm doomed, I better look into local chiropractors.
