FTM Transgender - What are the Effects of Hormones on Breasts?

Top surgery is really the most definitive way to address your D cup breasts.  There are ways to finance the operation.  Hormone therapy may have some effect on your breasts, and if it is part of your plan otherwise, it will benefit you to start before surgery.  I would not expect the type of resolution that you are looking for without surgery however.

Testosterone therapy in transgender men results in several masculinizing changes, including a reduction in breast size due to the shrinkage of glandular and fatty tissue. However, testosterone does not significantly affect breast skin, so while the tissue may become smaller and firmer, the skin often remains loose or saggy. This can result in a deflated appearance, particularly for individuals with larger breasts, as the skin doesn’t tighten to match the reduced volume. Additionally, testosterone increases muscle mass, contributing to a more masculine chest contour, and stimulates the growth of body and chest hair, further enhancing a male appearance.
While testosterone can produce some breast changes, it is generally not enough to fully achieve a masculine chest for individuals with larger breasts, as the skin may remain excessive or saggy. Most individuals with significant breast tissue or skin laxity will require top surgery, such as double incision or keyhole surgical approach, to remove excess tissue and skin and create a flatter, more defined chest. The effects of testosterone take time, often requiring months to a year for noticeable changes, and results can vary depending on factors like skin elasticity and initial breast size. In most cases, a combination of hormone therapy and top surgery is the most effective approach for achieving a masculine chest. I will mention that in my practice, we do not have a requirement for hormones to have surgery, but any CHANGES (starting/stopping) should be done 3-6 months before or after the planned procedure, and not peri-operatively to avoid fluctuations.
It is important to consult with a qualified gender-affirming breast surgeon who can customize your surgical plan with the best technique based on your individual anatomy and goals. Be sure to ask about experience and options for surgical techniques (such as incisions, liposuction, nipple reinnervation).

Many companies will require one year of HRT (Hormone replacement therapy). The #benefits of HRT for every patient, however, do include heavier #chest #muscles and more chest #hair; which can cover some incisions while you are healing. #HRT may be a strong consideration for most patients. WPATH (World Professional Association for Transgender Health) provides the best current standards of care for physicians to assist in the care of #transgender, #transsexual and #nonconforming patients.Hormone therapy for top surgery is not required unless you’re seeking coverage through #insurance. There are a number of states that now prohibit discrimination and legally require #insurance companies to provide transgender health coverage. If you live in a state where surgery coverage is not mandated by law, you still might be able to get your top surgery covered via student health insurance. To get #Top Surgery covered by insurance there are a number of requirements. Here are some of the obstacles you may face:1. Meeting the insurance company's basic criteria: legal adult status, Gender Dysphoria diagnosis, support letters from qualified mental health practitioners, your primary care provider and your surgeon.2. Having to pay out-of-pocket for surgery, then getting a reimbursement from the insurance company.3. Having to be evaluated by a board of in-network doctors.4. Finding in-network surgeons who have Top Surgery experience.Keep in mind, that coverage varies between health insurance companies, states, and plans. Read your policy completely, not only the summary, and look for the #exclusions and limitations section. Finally, call your insurance company's member services department, or, contact a #benefits representative and ask the following:• Is my selected surgeon a provider with my specific plan? (Make sure that you provide the representative with your surgeon's NPI number.)• If my surgeon is NOT a provider, does my plan have out of network benefits?• Does my plan cover gender confirmation Top Surgery?• How much is my deductible?Being each person varies, it’s important to be realistic about your goals and what is achievable. It's best to consult with your board-certified plastic surgeon about your concerns and to confirm if FTM Top is in your best interest.

Testosterone will have many masculinizing effects. This includes shrinkage of glandular breast tissue. Unfortunately, it will not shrink the skin to any noticeable degree. This will leave your breast looking like deflated pancakes.  You will need surgery in order to address this. If you have health insurance, you should check with your plan to see if they will cover the procedure.  If not, just start slowly saving so that you can get the results you want.  While it may take a little longer than you want it to, it will happen.
