How Hormone Replacement Therapy Affects the Pelvic Floor: What Transgender Patients Should Know

Hormone replacement therapy (HRT) can be a life-changing part of gender-affirming care. For many transgender and gender-diverse individuals, hormones help align physical characteristics with gender identity, reduce gender dysphoria, and improve overall well-being. While most conversations about HRT focus on changes such as body composition, voice, hair growth, or fat distribution, there is another area of the body that deserves attention: the pelvic floor.
At Bonneville Pelvic Health, we believe every patient deserves access to compassionate, evidence-based information about their body. Understanding how hormone therapy may affect pelvic floor function can help transgender individuals recognize symptoms early, seek appropriate support, and feel more empowered throughout their transition journey.
What Is the Pelvic Floor?
The pelvic floor is a group of muscles, connective tissues, and nerves located at the bottom of the pelvis. These muscles help support the bladder, bowels, and reproductive organs while also playing an important role in urinary function, bowel function, sexual health, core stability, and overall movement.
Like any other muscle group, the pelvic floor can become tight, weak, overactive, painful, or poorly coordinated. When this happens, symptoms may include:
Difficulty emptying the bladder
Pain during intimacy
Tailbone, hip, or low back pain
Feelings of pressure or heaviness in the pelvis
Everyone has a pelvic floor, regardless of anatomy, gender identity, or surgical history.
How Hormone Replacement Therapy Can Influence the Pelvic Floor
Hormones play a significant role in muscle health, connective tissue function, circulation, and tissue elasticity throughout the body. Because the pelvic floor is made up of muscles and connective tissues, it can also respond to hormonal changes.
Testosterone Therapy and Pelvic Health
For transgender men and transmasculine individuals, testosterone therapy can create changes in pelvic tissues over time. Some individuals experience increased muscle mass and strength, while others may notice changes in vaginal tissues, including dryness, irritation, or discomfort.
These tissue changes can sometimes contribute to:
Pelvic pain
Pain with penetration
Increased pelvic floor muscle tension
Urinary symptoms
Changes in sexual function
It is important to recognize that these symptoms do not occur in every person receiving testosterone. However, if symptoms arise, pelvic floor physical therapy can often help address the underlying muscular and tissue-related factors contributing to discomfort.
Estrogen Therapy and Pelvic Health
For transgender women and transfeminine individuals, estrogen therapy influences connective tissue, fat distribution, and muscle composition throughout the body. These changes can affect how the pelvic floor muscles function and coordinate. Research suggests that hormonal therapy may contribute to changes in pelvic floor muscle function through alterations in muscle mass, connective tissue characteristics, and pelvic support structures.
Some individuals may experience:
Urinary urgency or frequency
Pelvic floor weakness
Pelvic tension or pain
Changes in sexual function
Bowel dysfunction
While hormones alone are not always the direct cause of symptoms, they can be one contributing factor among many.
Pelvic Floor Dysfunction Is More Common Than Many People Realize
One common misconception is that pelvic floor concerns only become relevant after gender-affirming surgery. In reality, pelvic floor dysfunction is relatively common within the transgender community, even before any surgical intervention.
Studies have found that many transgender individuals undergoing evaluation for gender-affirming surgery already have symptoms of pelvic floor dysfunction, including bowel, bladder, and pain-related concerns.
This is one reason why pelvic health care can be valuable at any stage of transition, not only before or after surgery.
The Impact of Gender-Affirming Practices on the Pelvic Floor
Hormone therapy is just one piece of the picture. Many transgender and gender-diverse individuals also engage in gender-affirming practices such as binding, tucking, or packing.
These practices can sometimes influence posture, breathing mechanics, abdominal pressure, and muscle tension patterns throughout the body. Because the diaphragm, abdominal wall, and pelvic floor work closely together, changes in one area may affect the others.
This does not mean these practices should be avoided. Rather, it highlights the importance of individualized care that supports both gender affirmation and physical comfort.
Affirming Care Matters
Unfortunately, many transgender individuals have experienced healthcare environments where they felt misunderstood, dismissed, or unsafe. Access to affirming care is not simply a matter of comfort. It can significantly impact health outcomes and a patient's willingness to seek treatment.
At Bonneville Pelvic Health, we believe pelvic healthcare should be inclusive, respectful, and tailored to each individual's goals. Every patient deserves to feel heard, supported, and empowered throughout their care journey.
How Pelvic Floor Physical Therapy Can Help
Pelvic floor physical therapy offers a supportive and individualized approach to addressing symptoms related to pelvic floor dysfunction.
Depending on your goals and symptoms, treatment may include:
Education about pelvic health and anatomy
Pelvic floor muscle relaxation or strengthening
Manual therapy techniques
Scar tissue management
Mobility and posture training
Bladder and bowel retraining
Support for sexual function and comfort
For patients pursuing gender-affirming surgery, pelvic floor therapy may also help prepare the body before surgery and support recovery afterward. Research suggests that individuals who participate in pelvic floor therapy before and after surgery may experience improved outcomes and lower rates of pelvic floor dysfunction.
When Should You See a Pelvic Floor Physical Therapist?
If you are receiving hormone replacement therapy and experiencing pelvic pain, urinary symptoms, bowel concerns, discomfort with intimacy, or changes in pelvic function, a pelvic floor physical therapist may be able to help.
You do not need to wait until symptoms become severe. Early intervention often helps address concerns before they become more disruptive to daily life.
The Bottom Line
Hormone replacement therapy can bring many meaningful changes, but it may also influence pelvic floor health in ways that are not always discussed. Whether you are just beginning your transition, considering gender-affirming surgery, or simply looking for answers about new symptoms, pelvic floor physical therapy can be an important part of your support system.
At Bonneville Pelvic Health, we are committed to providing compassionate, evidence-based, and affirming pelvic health care for all individuals. Your experience is unique, and your care should be too.
