What Are The Options For Nonbinary Hormone Therapy?

Nonbinary hormone therapy uses hormones to align your physical body more closely with your gender identity. The main options are estrogen-based therapy, testosterone-based therapy, and low-dose versions of either. Some nonbinary people choose a combination approach, and others choose no hormones at all. The right path depends entirely on your goals, your health history, and what feels right for your body.

What Is Nonbinary Hormone Therapy?

Nonbinary hormone therapy is gender-affirming care for people who do not identify strictly as male or female. It is sometimes called gender-affirming hormone therapy (GAHT). The goal is not to move toward a binary “male” or “female” appearance. Instead, the goal is to create a body that feels more like your own.

This can mean many different things. Some people want a more masculine appearance. Some want a more feminine appearance. Others want a mix of features or simply want to stop certain physical changes they find distressing. Your treatment plan should reflect your specific goals, not a checklist.

Hormone therapy does not change who you are. It changes some physical characteristics. The psychological and emotional effects are real, but they come from feeling more at home in your body, not from the hormones themselves altering your personality.

What Are The Main Types Of Hormone Therapy?

There are two primary categories: testosterone therapy and estrogen therapy. Each produces distinct physical changes. Your choice depends on the changes you want.

Testosterone therapy is typically chosen by people who want a more masculine appearance. Common changes include a deeper voice, increased facial and body hair, changes in fat distribution, and increased muscle mass. Menstruation usually stops within a few months. Some changes are permanent, like voice deepening and hair growth. Others reverse if you stop treatment.

Estrogen therapy is typically chosen by people who want a more feminine appearance. Common changes include breast growth, softer skin, reduced body hair, and changes in fat distribution. Testicular size may decrease, and erectile function often changes. Breast growth is permanent. Most other changes reverse if you stop treatment.

Low-dose therapy is a third option. A lower dose of either hormone produces slower, subtler changes. Some nonbinary people prefer this because the effects are less dramatic and easier to control. It is important to understand that low-dose does not mean “half the effect.” Some changes are dose-dependent, but others happen regardless of dose once the hormone is present in your system.

How Do I Choose Between Testosterone And Estrogen?

This decision is deeply personal. There is no medical test that tells you which hormone is right for you. The choice comes down to the physical changes you want and the changes you want to avoid.

Ask yourself what bothers you most about your body right now. If your voice causes you distress, testosterone can permanently lower it. If chest shape is a major source of discomfort, estrogen can support breast growth. If body hair is the issue, estrogen may reduce it, while testosterone will increase it.

Some nonbinary people choose a hormone that aligns with their assigned sex at birth but at a low dose. Others choose the hormone associated with the opposite sex. There is no wrong answer. There is only what works for you.

Your clinician should walk you through the expected changes and their timelines. They should also discuss which changes are permanent and which are reversible. This information helps you make an informed choice rather than guessing.

What Changes Can I Expect On Testosterone?

Testosterone therapy produces changes over months and years. The timeline varies from person to person, but some patterns are consistent.

Within the first few months, you may notice your voice beginning to deepen. Menstruation usually stops within 3 to 6 months. Oilier skin and acne are common early on. Bottom growth — enlargement of the clitoris — typically begins within the first 6 months and is permanent.

Over the first year, facial hair starts to grow, and body hair increases. Fat redistributes away from the hips and thighs toward the abdomen. Muscle mass increases, especially if you exercise. Your libido often rises noticeably.

Some changes are permanent even if you stop testosterone. Voice deepening does not reverse. Clitoral growth does not reverse. Facial hair may thin slightly but does not disappear. Other changes — like fat distribution and menstruation — reverse when you stop treatment.

Testosterone is a controlled substance in the United States. It requires a prescription and regular monitoring. It is typically given as an injection, gel, or patch.

What Changes Can I Expect On Estrogen?

Estrogen therapy produces changes more slowly than testosterone. The timeline is longer, and some changes take years to fully develop.

Breast growth typically begins within 3 to 6 months. Growth continues for 2 to 3 years. The final size is highly individual and depends on genetics, age, and body composition. Skin becomes softer and drier. Body odor changes. Body hair may thin but does not disappear.

Fat redistribution occurs gradually over 1 to 2 years. Fat moves from the abdomen to the hips, thighs, and buttocks. Muscle mass decreases slightly. Testicular size decreases, and erections become less frequent. Sperm production drops significantly, which can affect fertility.

Estrogen does not change your voice. If voice pitch is a source of distress, voice training with a speech therapist is the standard approach. Estrogen also does not remove facial hair. Hair removal requires laser therapy or electrolysis.

Most estrogen changes are reversible if you stop treatment. Breast growth is the main permanent change. Estrogen is typically given as a pill, patch, gel, or injection.

What About Combination Or Microdosing Approaches?

Some nonbinary people use a combination of hormones or very low doses to achieve a specific balance. This is sometimes called microdosing.

Microdosing means taking a lower dose than is typically used for binary transition. The idea is to get some changes without the full effect. For example, a low testosterone dose might deepen the voice slightly and stop menstruation without producing heavy facial hair growth.

The evidence on microdosing is limited. Most clinical guidelines are based on standard doses for binary transition. Few studies have specifically examined low-dose or nonbinary protocols. This does not mean microdosing is unsafe. It means the outcomes are less predictable, and your clinician will need to monitor you closely and adjust based on your response.

Some people combine testosterone with a medication that blocks estrogen, or estrogen with a medication that blocks testosterone. This is sometimes called a “blocker plus hormone” approach. The goal is to suppress the dominant hormone while adding the desired one. This approach is used in standard transition care and can be adapted for nonbinary goals.

Be honest with your clinician about exactly what you want. “A little more masculine” and “mostly feminine but not fully” are legitimate goals. Your clinician can adjust doses and medications to work toward those goals, but they need clear information from you.

What Are The Risks And Side Effects?

Every medication has risks. Hormone therapy is no exception. The key is understanding the risks and monitoring them properly.

Testosterone risks: Testosterone can increase red blood cell count, which raises the risk of blood clots and stroke. It can negatively affect cholesterol levels. Acne and sleep apnea are common. There is some evidence it may increase the risk of heart disease, especially in people with other risk factors. Regular blood tests monitor red blood cell count and liver function.

Estrogen risks: Estrogen increases the risk of blood clots, especially in the first year of use. It can raise triglycerides and blood pressure. There is a small increased risk of breast cancer with long-term use, similar to the risk seen with menopausal estrogen therapy. Regular blood tests monitor hormone levels and liver function.

Both therapies can affect fertility. Testosterone typically stops ovulation, but this may return when treatment stops. Estrogen significantly reduces sperm production, and this may or may not recover. If fertility matters to you, discuss egg or sperm preservation before starting hormones.

You should not start hormone therapy if you are pregnant or planning to become pregnant. Testosterone is known to cause birth defects. Estrogen’s effects on pregnancy are less studied, but pregnancy while on estrogen therapy is not recommended.

Regular monitoring is not optional. Standard practice includes blood tests every 3 to 6 months in the first year, then annually. These tests check hormone levels, red blood cell count, cholesterol, and liver function.

How Do I Find A Provider?

Not all doctors are trained in gender-affirming care. You want a provider who has experience with nonbinary patients specifically, not just binary transition.

Start with your primary care doctor. If they are not comfortable managing hormone therapy, ask for a referral to an endocrinologist or a clinic that specializes in gender care. Many large cities have dedicated LGBTQ+ health clinics. Some offer telehealth appointments, which expands your options.

Planned Parenthood locations in many states offer gender-affirming hormone therapy. Some university health systems have dedicated gender health programs. Online services also exist, but be cautious. A legitimate provider will require blood tests and follow-up. If a service offers hormones without any monitoring, that is a red flag.

Before your appointment, write down your goals. What changes do you want? What changes do you not want? What are your health concerns? Bring this list. It helps your provider understand exactly what you need.
