Three different clients, three different starting points. One is a few months into estrogen and has stopped checking the mirror for evidence, having realized she was auditing her own body against a timeline nobody had actually promised her. One is preparing to start testosterone and wants to know what happens if his particular body doesn't follow the general script. The third doesn't want either endpoint most people picture — she's exploring a low, steady dose of testosterone specifically because she wants some changes and not others, and keeps running into medical literature that assumes everyone on hormone therapy is aiming for one of two destinations.

All three are doing the same underlying work: trying to plan for a process that resists tidy planning. The physical mechanics of gender-affirming hormone replacement therapy (HRT) are well documented by the providers who prescribe and monitor it. What gets less attention, across all three of these paths, is the emotional experience of actually living through a process that is genuinely individual, often nonlinear, and not obligated to follow anyone else's map — including the general one.

A note on scope: I'm a therapist, not a prescriber. Everything below is educational, drawn substantially from clinical overviews published by FOLX Health, a healthcare organization built specifically for the LGBTQIA+ community. Any actual dosing, monitoring, or medical decision-making belongs with your prescribing provider, not with this article.

Before getting into what's specific to testosterone, estrogen, or a gender-expansive approach that draws on both or neither in a binary sense, it's worth naming the thing that's true across all of it: dosage affects pace, but genetics does at least as much of the remaining work, in a way that closely resembles the unpredictability of adolescent puberty. Lower or more conservative dosing tends to produce slower, more gradual change; higher, consistently administered dosing tends to move faster. But even accounting for dose, some people grow a full beard and others don't, some voices drop dramatically and others shift subtly, some bodies redistribute fat exactly where someone hoped and others take their own route entirely. None of this is evidence that a process is failing. It's evidence that hormones interact with an already-existing genetic blueprint rather than uniformly overwriting it, and it can take years, not months, for a full picture to settle — regardless of which hormone, or combination, someone is on.

Three changes from testosterone tend to be permanent once they occur, regardless of whether someone later pauses or stops: a lower, deeper voice; facial and body hair growth; and clitoral/genital tissue enlargement, typically in the range of one to two centimeters. A separate set of changes require ongoing testosterone to maintain and can shift back if therapy is paused: increased muscle mass and strength, fat redistribution away from the hips and thighs (often toward the abdomen instead), changes to menstrual bleeding, and increased libido.

Other commonly reported, less predictably timed changes include oilier skin or acne, possible male-pattern hair thinning, increased sweating and appetite, chest tissue changes, and front hole or vaginal tissue changes — common and treatable, not something to quietly endure.

Does testosterone make your voice change? Yes, reliably, through the thickening of the vocal cords — though how low, and how fast, varies significantly by individual.

Only one change associated with estrogen therapy is considered permanent over time: breast tissue development, which typically begins within the first three months as "breast buds" and continues developing over the following two to three years.

Everything else tends to depend on continued estrogen — often alongside an anti-androgen like spironolactone, or progesterone — to maintain: softer skin, thinning or slowed facial and body hair growth, fat redistribution toward the hips and thighs, decreased muscle mass and strength, changes in libido and sexual function, decreased spontaneous erections, reduced sperm production and fertility, and a notable decrease in testicular volume, often 25 to 50 percent, after sustained time on estradiol. A DHT blocker can also help reduce scalp hair loss.

Does estrogen change your voice? No. Unlike testosterone, estrogen does not reverse a voice already deepened by a prior testosterone-driven puberty. Voice work, where wanted, happens through dedicated voice therapy or, in some cases, surgery — an active and growing specialty, not a gap to simply live with.

Does estrogen change your face? Yes, indirectly — fat redistribution, reduced oil production, thinner facial hair, softer skin, and some muscle loss all show up on the face, and fat migrating toward the cheeks can shift overall facial shape.

This is the piece of the conversation that standard hormone literature, built primarily around two endpoints, tends to underserve — and it deserves direct, explicit acknowledgment rather than an afterthought.

There is no requirement that hormone therapy aim for a fully binary endpoint. Some nonbinary and gender-expansive people pursue what's sometimes called micro-dosing testosterone: a lower, steady dose intended to produce a more androgynous presentation — some voice or body hair changes, for instance — without pursuing the full masculinizing trajectory a higher dose would drive. Others combine approaches in less standardized ways, working closely with a gender-affirming provider to titrate toward a specific, personally defined set of goals rather than a preset destination. Some pursue only one or two specific changes and deliberately stop there. Some don't take hormones at all and pursue affirmation through entirely different means. All of these are legitimate, and none of them require justifying against a binary transition as the "real" or "complete" version of the process.

What clients in this category consistently benefit from hearing, explicitly, is that "I want some of these changes and not others" is a complete, sufficient answer — not a preliminary stop on the way to somewhere else, and not something that needs defending to a provider, a family member, or themselves. The same genetics-and-dosage variability that applies to a fully masculinizing or feminizing trajectory applies here too, which means even a carefully chosen low dose will produce its own individual, sometimes unpredictable results rather than a precisely controllable menu of effects.

Two mirror-image cultural myths deserve direct pushback, because they shape how clients interpret their own very normal emotional experience on either hormone.

Testosterone does not make someone inherently angry or violent. Estrogen does not make someone moody, irrational, or "hysterical." Both ideas borrow from the same cultural habit of pathologizing hormones themselves rather than the systems — patriarchy chief among them — that actually produce gendered violence and dismiss emotional expression as instability. What clients on either hormone more commonly report is closer to the opposite: an increased capacity to access a fuller emotional range, often described as finally feeling at home enough in one's own body to actually feel things, rather than becoming less stable. Some testosterone patients notice a reduced ability to cry as easily, which can land as either relief or genuine loss. Some estrogen patients describe their moods as bigger or more expansive, which is generally experienced as a welcome return of feeling rather than a symptom to manage. Appetite and metabolism shifts in the first several months are common on either hormone and can move in either direction. None of this is a referendum on whether the process is going "correctly."

A few things hold across all three paths described here, whether you're the client living through this or the clinician supporting someone who is.

First, the gap between a hoped-for timeline and an individual body's actual pace is one of the most common sources of quiet, unspoken distress in this population — regardless of which hormone, or how much, someone is taking. It deserves direct attention rather than an assumption that it will resolve on its own. Checking for proof in the mirror every morning, or measuring progress against someone else's documented experience, is a very human response to genuine uncertainty, and it's worth naming and gently interrupting.

Second, the myth-work matters clinically, not just rhetorically. A client who has absorbed a lifetime of cultural messaging about what testosterone or estrogen "does to people" may misread their own genuinely expanded emotional range as something concerning rather than something to meet with curiosity.

Third, for nonbinary and gender-expansive clients specifically, the clinical task is often less about tracking physical change and more about actively defending the legitimacy of a self-determined, non-binary goal against a medical and cultural framework that keeps assuming a binary one. That defense is real clinical work, not a side note.

Fourth, gender-affirming hormone therapy across all of these paths is generally associated with real improvement in dysphoria, identity affirmation, and overall quality of life — but "generally" leaves real room for grief, impatience, and adjustment even when the overall direction is correct and wanted. That grief doesn't mean a decision was wrong. It means a real, embodied change is underway.

Finally, if therapy is pausing or changing — for any of these paths, for any reason, whether insurance, access, side effects, or personal reassessment — that conversation belongs with a prescribing provider first, ideally before the pause rather than after, so that expected reversals (menstruation returning, mood and energy shifts, muscle and fat redistribution reversing, testosterone-driven changes that were never permanent settling back) are anticipated rather than discovered.

The three clients from the opening of this piece didn't need a more precise timeline, a faster process, or a clearer justification for what they wanted. They needed permission for their own path — binary or not, fast or not, complete or intentionally partial — to be the correct one simply because it was theirs.

This article is for educational purposes only and is not medical advice. It draws substantially on clinical information published by FOLX Health, a gender-affirming healthcare organization. Questions about starting, adjusting, pausing, or stopping hormone therapy of any kind should go to your prescribing provider — this piece addresses the psychological and emotional experience of the process, not medical management of it.
