You’re staring at that vial of T-cypionate or the pump of AndroGel and thinking about the next forty years. It’s a heavy thought. Most guys starting their transition are so focused on the immediate "wins"—the voice drop, the first chin hairs, the way your shirts finally fit right—that the logistical reality of the "forever" part doesn't hit until later.
So, do you have to take testosterone forever ftm?
The short answer is: it depends on your goals and your anatomy. If you want to maintain every single masculine secondary sex characteristic and you’ve had certain surgeries, the answer is usually yes. But "forever" is a long time, and the medical nuance here is way more interesting than a simple yes or no.
Why Your Body Needs a Primary Sex Hormone
Basically, the human body isn't designed to run on empty. We need a dominant sex hormone—either testosterone or estrogen—to keep our bones from turning into Swiss cheese. This isn't just about looking masculine; it’s about systemic health.
If you still have your ovaries, you can technically stop testosterone at any point. Your body will just "flip the switch" back to estrogen. You’ll lose some muscle mass, your fat will migrate back to your hips, and your periods will likely restart. But if you’ve had a total hysterectomy and bilateral oophorectomy (removal of both ovaries), your body no longer has a factory to produce estrogen.
In that scenario, if you stop T, you’re entering a state of surgical menopause. This isn't just about hot flashes. We’re talking about a massive spike in the risk for osteoporosis and cardiovascular issues. Dr. Maddie Deutsch, a leading expert in transgender health at UCSF, often emphasizes that for those without gonads, hormone replacement isn't elective; it’s a foundational health requirement.
What Happens if You Just Stop?
Let’s say you’ve been on T for five years. You’re happy. You’ve got the beard, the deep voice, and the bottom growth. You decide you’re done with the needles.
Some changes are permanent. They’re burned into your DNA now. Your voice won't magically go back up because the vocal folds have physically thickened. Your clitoral growth (bottom growth) is generally permanent, though it might lose some of its "fullness" without active T in your system. Hair follicles that have been terminalized—meaning they’re now growing thick beard hair—won't just disappear, though the hair might grow slower or get slightly softer.

But other things vanish fast.
The "T-glow" or that specific skin texture? Gone. Your fat distribution will shift back to a feminine pattern within months. That mental clarity or "rightness" many trans men describe feeling on T? That can evaporate, often replaced by the return of gender dysphoria or just a general sense of lethargy.
The "Low Dose" or Maintenance Phase
You don't necessarily have to stay on a high dose forever. Many guys, after ten or fifteen years, talk to their endocrinologists about tapering down to a "maintenance dose."
As we age, cisgender men naturally experience a decline in testosterone levels. It’s a process called andropause. If you’re sixty years old and still pinning the same dose you used at twenty-five, your levels might actually be higher than your cis peers. Some people choose to lower their dose as they get older to mirror a more "natural" aging process, which can also take some strain off the liver and heart.
The Surgical Factor: Oophorectomies and Bone Density
This is where the "do you have to take testosterone forever ftm" question gets serious. If you keep your ovaries, you have a safety net. You can stop T, and while you might hate the physical changes, your bones will stay strong because estrogen will take back over.
But a lot of us opt for a full hysterectomy.
Once those ovaries are gone, you are "hormone dependent." If you stop taking T and don't replace it with estrogen, your bone mineral density will drop. This is a quiet killer. You won't feel your bones getting weaker until you break a hip at fifty.

Realistically, if you’ve had an oophorectomy, you are committing to some form of hormone therapy for the rest of your life. It doesn't have to be shots. It could be patches, gels, or even long-acting pellets like Testopel that only need to be inserted every few months. But you need something in the tank.
Managing the "Forever" Fatigue
Let’s be honest: doing shots every week for forty years sounds exhausting. It is.
Medical burnout is a real thing in the trans community. There are weeks where you just don't want to see another needle. This is why many long-term transitioners switch methods.
- Nebido/Aveed: These are long-acting injectables (undecanoate) that you only get every 8 to 12 weeks. It’s a game-changer for people who hate the weekly ritual.
- Gels and Creams: Great for keeping levels stable, though they require a daily habit.
- Pellets: These are tiny cylinders implanted under the skin. They dissolve slowly over 3-6 months.
Changing the delivery method can make the "forever" part feel less like a chore and more like just taking a daily vitamin.
Health Risks of Long-Term T
We have to talk about the red blood cells. Polycythemia—where your blood gets too thick because T stimulates red blood cell production—is one of the most common reasons doctors get nervous about long-term use.
If your hematocrit levels get too high, your blood becomes like sludge. This increases the risk of blood clots and strokes. This is why you can't just "ghost" your doctor. You need those blood panels every year. Forever.
Usually, this is managed by adjusting the dose or, in some cases, donating blood regularly to thin things out. It’s manageable, but it requires vigilance. You also have to watch your lipid profiles. Testosterone can sometimes mess with your "good" vs "bad" cholesterol, which is why heart health becomes the priority as you hit your 40s and 50s.

The Psychological Long Game
For many, the question of whether they have to take T forever is less about biology and more about identity.
There’s a subset of the community that feels "done" with their transition after a decade. They feel they’ve achieved the masculinization they need and are comfortable letting things settle where they may. If they still have ovaries, they might stop T to avoid the hassle of HRT.
This is a valid choice. Transition isn't a one-way street with a mandatory destination. It’s your body.
However, the majority of trans men find that the mental health benefits—that baseline "hum" of the right hormones—is something they aren't willing to give up. The brain is a hormonal organ, too.
Practical Steps for the Long Haul
If you’re feeling overwhelmed by the idea of lifelong hormone therapy, focus on the infrastructure of your care rather than the "forever" timeline.
- Prioritize Bone Health: If you are considering stopping T or lowering your dose significantly, get a DEXA scan. Know your baseline bone density.
- Keep Your Ovaries? If you haven't had bottom surgery yet, think long and hard about whether you want to keep one or both ovaries. It’s essentially an "insurance policy" for your endocrine system.
- Switch Methods Regularly: Don't feel married to the needle. If you’re getting "shot anxiety" after five years, try the gel. If the gel is a mess, look into pellets.
- Blood Work is Non-Negotiable: Even if you feel fine, get your labs done. The biggest risks of long-term T (liver strain, thick blood, high cholesterol) are often silent until they aren't.
- Cardiovascular Focus: Since T can shift your heart disease risk closer to that of cisgender men, prioritize cardio and a heart-healthy diet. Your "forever" on T depends on your heart staying strong enough to handle it.
Ultimately, the "forever" in "do you have to take testosterone forever ftm" isn't a prison sentence. It’s a management plan. Just like someone with a thyroid condition takes a pill every morning, or someone with diabetes manages their insulin, HRT is just a tool to keep your body running in a way that feels like home. You have the agency to adjust that tool as you age, provided you stay informed and keep your medical team in the loop.
