Genetic factors play a significant role in determining breast shape and size in transgender women, just as they do in cisgender women. However, the specific genetic contributions may differ due to the distinct hormonal and developmental pathways involved in transgender women’s breast development.

Heritability: Breast size and shape are moderately heritable, with estimates ranging from 40% to 60%. This means that genetic factors contribute significantly to the variability in breast size and shape, even among transgender women.

Genetic variants: Large-scale genotyping studies have identified several genetic loci associated with breast size and shape. For example, a study found a new locus at 22q13.2 associated with female breast size. However, it is essential to note that these findings are primarily based on cisgender women and may not directly translate to transgender women.

Hormonal influences: Cross-sex hormone therapy (estrogen and antiandrogens) plays a crucial role in shaping breast development in transgender women. Genetic factors may interact with hormonal influences to modulate breast growth and shape.

Predicting Breast Shape and Size in Transgender Women

Currently, there is no reliable method to predict breast shape and size in transgender women based solely on genetic factors. The complexity of breast development, influenced by a combination of genetic, hormonal, and environmental factors, makes prediction challenging.

Individual variability: Breast development in transgender women exhibits significant individual variability, even among those receiving similar hormone therapy regimens.

Limited genetic data: While genetic studies have identified associations with breast size and shape, the available data are primarily based on cisgender women, and the applicability to transgender women is unclear.

Hormonal and environmental factors: Breast development in transgender women is heavily influenced by hormonal and environmental factors, such as age, body mass index (BMI), smoking, and treatment regimen. These factors can interact with genetic predispositions to modulate breast growth and shape.

In conclusion, genetic factors do influence breast shape and size in transgender women, but the specific contributions are not well understood due to limited data and the complexity of breast development. Currently, there is no reliable method to predict breast shape and size based solely on genetic factors. Instead, individualized assessments and follow-up evaluations are necessary to monitor breast development in transgender women undergoing hormone therapy.

Yeah, I read something like that too... I've just been kind of sensitive to dysphoria due o my depression lately, so I'm not even sure if I am actually unhappy about my chest or not... like, earlier today I snapped a pic in which my boobies looked alright!☆ Thanks for the message and encouragment!☆

Also: here is the mentioned pic... it's... very silly (I'm making an attempt on fashion design lmao)

Today I traveled to Seattle for my appointment to see if I am a candidate for breast augmentation.

Today’s appointment was supposed to be televisit which I dreaded as my first televisit went bust.

I left home at 6:30am to travel to Seattle and made it there in 40 minutes. I pulled into Lindeman Pavilion and had to go through an intense COVID-19 review.

Upstairs to the 9th floor, I checked in and walked through a maze of blue tape to keep everyone 6 feet apart.

I waited in the dermatology unit of the Plastics department (turn left to go to Facial Plastics) and was called back and sent to a room. I was told I did not need to underdress which made me happy as I don’t like to see myself.

Dr. Schmitt came in and was very friendly as he greeted me with a elbow bump as we both were masked.

We discussed my health and my mental state as he was concerned about my cystic fibrosis and the surgery.

I have feared that CF might impact my surgery as there is risks and he said that he is deciding if to operate or not, but he is swaying to not.

We talked for awhile as he said ‘If you seemed uncertain or not taking this serious, I’d say no right now; but you seem well aware.’

He emphasized that he will not do surgery as he feared that because my pectoral muscle will be cut, I may not want to breathe deep and this could cause pneumonia. He said over and over ‘I would be so upset if I did surgery on you while you are healthy and caused you to contract pneumonia. As your surgeon, you are ready for surgery; but as your doctor...I must think of your health.’

He offered a solution:

‘You have facial feminization with Dr. Nuara. Facial feminization surgery isn’t as severe as breast augmentation; but your CF just concerns me. Let’s say that your surgery and anesthesia go successful; wait three months and come back to schedule an appointment.’

I agreed to this plan and we talked about my breasts.

He looked at my chest and said that from looking at my frame, I would need a 400cc silicone implant.

He showed how it would be implanted (intramuscular) and it would fill out my chest. The incision would be a 9cm cut under breast.

He said the surgery would be 90 minutes and I’d get to go home that day. No severe lifting for five weeks.

He had me remove my shirt and bra and seemed shocked, ‘Your breasts have moderate development!’

‘I was sized for a 44C.’

‘Your not a C, more like a full B...but nicely developed for transitioning.’

He took pictures for reference and then had me go as there was nothing else to discuss. He caught me before the door.

‘I’m going to submit your claim to your insurance for approval. If you get an approval letter, give us a call as sometimes we don’t receive notification.’

As a woman, I’ve often wondered about the impact of bras on breast growth. When I was younger, I heard many stories. They said wearing a bra to bed could stop development or cause sagging. But, over time, I’ve learned that these are mostly just rumors. There’s no proof that sleeping in a bra is bad for your breasts. Our breasts grow and change mostly due to genetics, hormones, age, and if we’ve…

As a girl moving through puberty, changes in my body have caught my eye. Breasts growing and changing bring both joy and worry. I often think about what might affect this growth. Not long ago, a Harvard study pointed a finger at tight clothes, which surprised me. This study found that very tight bras can cut down on blood flow. They can also hurt the lymph tissues in your chest. This reduces the…
