Starting testosterone as a trans man is a medical process with clear, established pathways, and knowing what those pathways look like before your appointment makes the conversation much easier. You don’t need to prove anything or perform distress. You need to find the right provider, understand your options, and walk in prepared.
Two Main Pathways to Getting a Prescription
How you access testosterone depends on which clinical model your provider follows. The two dominant approaches in the U.S. are the informed consent model and the mental health referral model, and they differ significantly in what’s required of you before treatment begins.
Under the informed consent model, you don’t need a therapist’s letter or a formal gender dysphoria diagnosis from a mental health professional. Instead, your prescribing clinician walks you through the risks, benefits, and expected changes of testosterone, confirms you understand them, and writes the prescription. This model treats your capacity for self-knowledge as sufficient. It does not rule out mental health support if you want it, but it separates therapy from gatekeeping. Many Planned Parenthood locations, LGBTQ health centers, and telehealth services use this model.
The mental health referral model, based on the World Professional Association for Transgender Health (WPATH) Standards of Care, requires a referral letter from a mental health professional who has assessed you and documented your readiness for hormone therapy. Older versions of this framework required three to six months of psychotherapy or a period of living full-time in your identified gender before any medical intervention. Current guidelines are less rigid, but the letter requirement remains. If your provider follows this model, you’ll need to see a therapist or psychologist first, which adds time and cost but can also be genuinely helpful if you want that support.
Neither pathway is more “legitimate” than the other. Both result in the same prescription. The informed consent route is typically faster, sometimes resulting in a prescription at your first or second visit. The referral route can take weeks to months depending on therapist availability.
Finding the Right Provider
Not every primary care doctor is experienced with gender-affirming hormone therapy, so finding a provider who already does this work saves you from having to educate your clinician during the appointment. WPATH maintains a searchable provider directory with nearly 1,800 listed members, filterable by state and specialty, including endocrinology, primary care, and nurse practitioners. The GLMA (formerly the Gay and Lesbian Medical Association) also maintains a provider directory. Local LGBTQ centers often keep referral lists of clinicians their community members have had positive experiences with.
If you live in an area with limited options, telehealth services that prescribe testosterone through informed consent have expanded significantly. These can be especially useful for people in rural areas or states with fewer trans-affirming providers.
What to Say at Your Appointment
You can be straightforward. Something like “I’m a trans man and I’d like to start testosterone” is a perfectly fine opening. You don’t need a rehearsed speech about your childhood or a detailed narrative of your gender history. A provider experienced in this care will guide the conversation from there.
What helps is being ready to discuss a few practical things: how long you’ve been considering hormone therapy, whether you’ve socially transitioned, any current medications, your mental health history (not as a barrier, but because some conditions need monitoring during hormonal changes), and whether you’ve thought about fertility preservation. You’re not being tested. These questions inform your treatment plan.
If your provider seems unfamiliar with transgender care, pushes back without clinical reasoning, or insists on requirements that don’t match established guidelines, that’s a sign to find a different provider, not a sign that you need to argue harder.
Baseline Lab Work Before Starting
Before prescribing testosterone, your doctor will order blood work to establish a baseline. According to Johns Hopkins Medicine’s dosing guidelines, this typically includes a complete blood count (CBC), total testosterone and estradiol levels, and a pregnancy test if there’s any possibility of pregnancy. Depending on your individual risk factors and family history, they may also check liver enzymes, a lipid panel, and blood sugar markers.
These aren’t hurdles. They give your provider reference points to monitor your health over time. Testosterone affects your red blood cell count, cholesterol, and liver function, so knowing where you started matters for catching problems early.
Choosing a Delivery Method
Testosterone comes in several forms, and your doctor will help you choose based on your preferences, lifestyle, and how your body responds. The most common options for trans men are injections, topical gels, and patches.
- Injections are the most widely used. They’re typically given weekly, either intramuscularly or subcutaneously. Injectable testosterone tends to produce higher overall testosterone levels than other methods, which some people prefer. The tradeoff is that levels can spike after injection and dip before the next one, which some people feel as mood or energy fluctuations.
- Topical gels are applied daily to the skin. They produce more stable hormone levels throughout the day but require consistent daily application and care to avoid transferring the gel to other people through skin contact.
- Patches are another daily option that provides steady absorption, though skin irritation at the application site is a common complaint.
Injectable forms are often the least expensive option, which matters because cost and insurance coverage vary widely between formulations.
Insurance and Coverage
Many insurance plans cover testosterone for gender dysphoria, but prior authorization is common. Based on documentation from major insurers like UnitedHealthcare, approval for topical testosterone, patches, or oral forms typically requires a documented diagnosis of gender dysphoria as defined by the DSM, plus confirmation that you’re using the hormone to align your physical characteristics with your gender. Authorizations are usually issued for 12 months at a time.
Some injectable formulations may require you to try a less expensive generic version first before a brand-name option is approved. If your insurance denies coverage, your provider’s office can often handle the appeal. GoodRx and similar discount programs can also reduce out-of-pocket costs significantly for generic injectable testosterone, which is sometimes cheaper to pay for in cash than through insurance.
What Changes to Expect and When
Changes from testosterone happen gradually. Shifts in fat distribution and muscle mass typically begin within 12 to 16 weeks and stabilize between 6 and 12 months, though subtle changes can continue for years. Voice deepening, increased body hair, and skin oiliness are among the earlier changes. Fat redistribution from hips and thighs to the abdomen follows a slower timeline.
Your doctor will schedule a follow-up around three months after starting to check your levels and see how you’re responding. After that, expect annual check-ins at minimum, with blood work to monitor your red blood cell count, liver function, and hormone levels.
Health Risks Worth Understanding
The most well-documented risk of testosterone therapy is erythrocytosis, a condition where your body produces too many red blood cells, which can increase the risk of blood clots. In a large long-term study of trans men on testosterone, about 11% developed elevated red blood cell counts. The biggest jump happens in the first year, when average levels rise noticeably, but the probability of developing erythrocytosis continues to climb over time, reaching roughly 38% after ten years.
Injectable testosterone carries a higher risk of erythrocytosis than gels or patches because it produces higher peak hormone levels. Smoking more than doubles the risk, and higher body weight also increases it significantly. If your levels get too high, the typical first steps are switching from injections to a topical form, quitting smoking if applicable, and weight management. Blood donation or therapeutic blood draws are also used when levels climb into a concerning range. This is why regular blood monitoring isn’t optional.
Fertility Before You Start
Testosterone often suppresses ovulation, but it’s not reliable contraception. If you want biological children in the future, this is a conversation to have before starting treatment. Egg freezing is an option, though it’s expensive and involves a stimulation cycle that some trans men find dysphoria-inducing.
If you’re already on testosterone and later want to conceive, research shows that menstrual cycles generally return after stopping testosterone, though the timeline varies. Some studies have found that ovulatory function recovers, with evidence of normal egg development resuming. However, the long-term functional impact of extended testosterone use on reproductive tissue isn’t fully settled, and longer exposure may involve more significant changes to ovarian tissue. The clearest takeaway: if fertility matters to you, discuss preservation options early rather than assuming you can sort it out later.
Questions to Bring to Your Appointment
Walking in with a short list of questions helps you get the most from your visit and signals to your provider that you’re an engaged patient. Useful ones include:
- Which delivery method do you recommend for me, and why?
- What’s the monitoring schedule for blood work?
- How will this interact with any medications I’m currently taking?
- What should I know about hair loss risk, and are there options if it happens?
- Can we discuss fertility preservation before I start?
- What does my insurance typically cover, and will your office handle prior authorization?
You’re not asking for permission. You’re collaborating with a clinician on your care plan. The right provider will treat the conversation that way.
