Orchiectomy: The Feminising Surgery People Rarely Talk About

An orchiectomy is surgery to remove the testes, and as a feminising gender-affirming surgery it can be done entirely on its own, without a vaginoplasty. It removes the body’s main source of testosterone, which usually changes what hormone therapy needs to do afterwards¹. It is accessed through the same assessed pathway as other gender-affirming surgery, under the WPATH Standards of Care, Version 8 (SOC-8), 2022².

I noticed while I was waiting that this operation barely appears in the guides, even though it came up constantly in conversation with other trans women. Some had chosen it as their only surgery; others had it years before anything else, simply to get off the anti-androgens. Almost nobody had found a clear page about it. So here it is, reviewed by a consultant gender-affirmation surgeon: what it does, what it means for hormones and fertility, and the one question to settle before you book it. For the wider context, see our overview of gender-affirming surgery and of feminising surgery for trans women.

What an orchiectomy is, and what it is not

It is the removal of the testes, and nothing else: it does not create a vulva, a vaginal canal, or any external change beyond the scrotum itself. That distinction matters, because people sometimes hear “genital surgery” and assume one procedure covers all of it. Vaginoplasty creates a vulva and a canal and includes removal of the testes as part of the larger operation. A standalone orchiectomy is a smaller, more contained procedure with a single aim.

It is one recognised feminising option among several, alongside vaginoplasty, vulvoplasty, breast augmentation, facial feminisation, and voice work¹. Surgery of any kind is one option among many and not a requirement of being trans. Plenty of trans women have no genital surgery at all, and that is a complete life, not an unfinished one.

Why people choose it on its own

The two reasons I heard most often were hormonal relief and the length of the wait. With the testes removed, the body’s principal source of testosterone is gone, so the medication that suppresses it is often no longer needed. For people who find anti-androgens difficult to tolerate, or who dislike being on several drugs indefinitely, that simplification is the whole point.

The second reason is time. Waits for genital surgery run into years in many systems, and on the NHS you reach a surgical provider only after an assessment at a Gender Dysphoria Clinic, where a first appointment commonly takes several years¹. An orchiectomy is a shorter, lower-demand operation, and for some people it becomes a step that makes the remaining wait bearable rather than a substitute for it.

And for many people it is simply the surgery they want. Not everybody wants a vaginal canal or the aftercare that comes with it, and choosing to stop here is a decision, not a compromise.

What it means for hormones

Once the testes are removed, the hormone plan almost always needs reviewing, and this is a conversation to have before the operation rather than after it. Anti-androgens are commonly stopped, because there is little testosterone left to block. Oestrogen continues, and continuing it matters: the body still needs a source of sex hormone, and stopping it after the gonads are gone has consequences for bone health over years.

That review belongs to your prescribing clinician, not to a website and not to you alone. What I would encourage is asking, at the consultation, who is going to change the prescription and when. In my own experience the surgical side and the hormone side of trans healthcare do not always talk to each other as smoothly as you would hope, and knowing which clinician owns that decision saves a frustrating month afterwards.

Fertility, and why the order matters

An orchiectomy ends natural fertility permanently, so if sperm storage is something you might want, it has to happen before the operation. There is no route back afterwards³.

This is the part I would ask anyone to slow down on. Feelings about parenthood are not fixed, and the person deciding at twenty-five is making a decision on behalf of the person they will be at forty-five. That is not an argument for storing sperm, and it is not an argument against having the surgery. It is an argument for making the choice deliberately, with the information in front of you, rather than by default because nobody raised it in time. We go through the options in fertility preservation before gender-affirming surgery.

The question to settle first: might a vaginoplasty follow?

This is the single most important thing to raise before an orchiectomy, and the thing most likely to be missed. Penile inversion vaginoplasty uses scrotal skin to build the labia and part of the vaginal lining. A standard orchiectomy performed without that future operation in mind, and the gradual loss of scrotal tissue afterwards, can reduce what a later surgeon has to work with.

It does not automatically rule a vaginoplasty out, and surgeons can plan the incision differently when they know a canal may be wanted later. But the planning has to happen in advance. If there is any chance you will want a vaginoplasty in future, say so at the consultation, ask how the surgeon would approach the operation with that in mind, and ask what it would mean for the later procedure. For what that operation involves, see vaginoplasty, and for how to interrogate a surgeon properly, questions to ask before gender-affirming surgery.

Recovery and how it fits the pathway

Recovery is short by the standards of this field, but it is still surgery under anaesthetic with real healing, restrictions, and a scar. It is often a day case or a single overnight stay, with a return to light activity within a week or two and a longer restriction on heavy lifting; your surgeon gives you the timings that apply to you⁴. Recognised risks, including bleeding, infection, and changes in sensation, are explained at consultation as part of informed consent.

The pathway is the same one that governs the rest of this site’s procedures: individualised assessment, capacity, and informed consent under SOC-8, 2022². Regret after gender-affirming surgery is about 1 in 100 across a large pooled meta-analysis of around 7,900 patients, low but not zero, and worth weighing honestly rather than dismissing⁵. Nothing here is personal medical advice; your own clinical team can assess you as an individual. To understand the assessment and referrals, see the pathway to gender-affirming surgery.
