Supporting someone who is starting hormones

This one is for the people around someone starting hormones: a partner, a parent, a close friend, an adult child. You may be fully behind the decision, quietly worried, or somewhere in between. Either way you probably have questions you don't want to ask them, and some you shouldn't. This page tries to answer the first kind, and gently flag the second.

Nothing here is medical advice, and it isn't about whether someone should take hormones. That's their decision, made with a prescriber. It's about what the next year or two tend to look like from the outside, and how to be useful during it.

What the first year actually looks like

Hormones work on the timescale of puberty, because they set off a second one. That means change is slow, uneven and mostly invisible for the first few months. Skin, libido and mood often shift in the first weeks. Visible body changes take many months and keep going for two or three years or more. Some things never change on hormones alone: estrogen doesn't raise a voice that has already dropped, and testosterone doesn't remove breast tissue.

Knowing that helps in two ways. You won't be startled by how little seems to happen at first, and you won't add to the impatience the person on hormones is probably already feeling. What changes, and when on feminizing hormones and the testosterone timeline set out the rough order if you want the detail.

Some changes are permanent and some reverse if hormones stop. If that's the worry sitting underneath your questions, which changes from hormones are permanent? is the honest version, written for exactly that reader as much as for the person starting.

Mood: what's hormones, and what isn't

People often expect hormones to change someone's personality. They don't. What they do is shift things at the edges: some people feel calmer and more settled on estrogen, some feel more energy or a shorter fuse on testosterone, and a lot of people feel noticeably better simply because something that felt wrong for a long time is finally being addressed.

There are also ups and downs that have more to do with life than with the medicine. Coming out at work, waiting for changes that feel too slow, other people's reactions, and money all weigh on mood in the first year. It's easy, and unfair, to blame every bad day on "the hormones". If you're worried about someone's mood, say what you've noticed and ask how they are, rather than offering a theory about their dose. Mental health on HRT covers how mood and hormones interact, and how to tell a dose problem from a life problem.

If someone talks about wanting to die or harm themselves, take it seriously and help them get urgent support, the same as you would for anyone.

Safety, without hovering

Hormones are routine medicine with a small number of risks worth knowing about. The main one on estrogen is blood clots. On testosterone it's thicker blood, picked up on routine blood tests. Prescribers manage both with check-ups and blood tests, roughly every three months in the first year and then once or twice a year.

It's worth knowing the few symptoms that need help the same day, because you may be the one in the room: on estrogen, a painful swollen leg, sudden breathlessness or chest pain; on either, signs of a stroke such as a drooping face, a weak arm or slurred speech. Feminizing hormone risks and masculinizing hormone risks list them. Beyond that, monitoring is the prescriber's job. Asking someone every week whether they've had their bloods done helps nobody.

If they smoke and they're on estrogen, quitting is the one change that makes the biggest difference to their safety, and support to quit, rather than pressure, is something a partner or family can genuinely offer.

Practical things that help

• Turning up. Offering a lift to a blood test or a first appointment, or sitting in the waiting room, means more than it sounds. Some people want company in the room; most don't. Ask.
• Injections. If they inject, learning how to help, or simply being around for the first few on their own, can take the edge off. Used needles go in a sharps bin, not the household rubbish; injecting hormones covers the basics.
• Money. Hormones are cheap compared with most medicine, but appointments and blood tests add up, especially privately. Cost and insurance has rough figures. If you share finances, talk about it plainly.
• Names and pronouns. If they've asked you to use a new name or pronouns, practise. Getting it wrong occasionally is normal; correcting yourself briefly and moving on is the respectful version.
• Admin. Changing records, chasing a referral, sitting on hold with an insurer. Some people would love the help; some want to do it themselves. Ask.

Questions to leave alone

Some questions come from a good place and still land badly. What's in their underwear, whether they're "having the surgery", what their levels are this month, whether they're sure. If they want to tell you, they will. If you need to understand something, a page like this one is a better first stop than asking them to explain their body.

Fertility is a sensitive one for parents in particular. Hormones can reduce or end fertility, and there are options for storing sperm or eggs before starting. It's reasonable to make sure they know that, once, and then leave the decision with them. Fertility covers the options.

Looking after yourself

If you're a partner, hormones can change libido and sex, sometimes a lot, and it's normal for that to need talking about. If you're a parent, you may be grieving an idea of your child's future while also wanting to support them, and both can be true at once. Many areas have support groups for families and partners of trans people, and talking to people a few years further along is often more useful than any website, this one included.

You don't need to have it all worked out before you can be supportive. Showing up, asking instead of assuming, and letting them lead are most of it.

This is general information, not medical or psychological advice. The person on hormones and their prescriber make the decisions about their treatment.
