Gender-affirming care – the approach of affirming a person’s self-defined gender identity and changing the appearance of the body to align with this identity – is essentially the only response to gender dysphoria. So, this treatment, these puberty blockers, cross-sex hormones, and surgical transitions, must have a solid track record of success, right?
Unfortunately, no. There are no studies that compare the health outcomes of children and adolescents who receive gender-affirming care with those whose gender dysphoria resolved after puberty without medical or surgical intervention. We’ll repeat that. There are no studies that compare the health outcomes of children and adolescents who receive gender-affirming care with those whose gender dysphoria resolved after puberty without medical or surgical intervention.
The reason where there are no studies comparing whether watchful waiting or gender-affirming care is the better response to gender dysphoria is primarily because researchers have considered it unethical to randomly selecting some patients for medical transition and some patients for a wait and see approach.1 Such a random assignment is critically important to determine cause and effect and to generalize results to a broader population. Researchers have devised other ways to design studies to measure the impact of gender-affirming care on patients, but none of them are of high quality or high confidence.2
There are no studies that compare the health outcomes of children and adolescents who receive gender-affirming care with those whose gender dysphoria resolved after puberty without medical or surgical intervention.
In other words, there is no gold-standard evidence that receiving remarkably invasive and irreversible gender-affirming care leads to better outcomes than interventions that actively decrease cross-gender identification or watchfully wait for gender dysphoria to subside.3
In fact, there is lots of evidence that suggests that gender-affirming care is actually harmful.
Let’s start with puberty blockers. Puberty blockers are often compared to hitting the pause button on puberty to allow time for a child to explore their gender identity. But endocrinologist William Malone describes how, after a while, “the [endocrine] system ‘goes to sleep’ and at some point it may not wake up.”4 Abigail Shrier notes, “we wouldn’t consider a drug that stunted your growth in height and weight to be a psychologically neutral intervention – because it isn’t one… and yet the change in height brought on by growth hormones is arguably far less profound than that caused by puberty’s years-long flood of hormones, which transform our bodies into sexual adults.”5 Another concern is that one of the drugs commonly used to block puberty, Lupron, is the same drug was used to chemically castrate sex offenders. It is approved to treat symptoms of prostate cancer, endometriosis, and precocious puberty but is used “off-label” in a medical transition.
“We wouldn’t consider a drug that stunted your growth in height and weight to be a psychologically neutral intervention – because it isn’t…”

Common side effects of puberty blockers are redness/burning/stinging/pain/bruising at the injection site, hot flashes, increased sweating, night sweats, tiredness, headache, upset stomach, nausea, diarrhea, constipation, stomach pain, breast swelling or tenderness, acne, joint/muscle aches or pain, trouble sleeping (insomnia), reduced sexual interest, vaginal discomfort/dryness/itching/discharge, vaginal bleeding, swelling of the ankles/feet, increased urination at night, dizziness, breakthrough bleeding in a female child during the first 2 months of leuprolide treatment, weakness, chills, clammy skin, skin redness, itching or scaling, testicle pain, impotence, depression, increased growth of facial hair, and memory problems.6
And then there is cross-sex hormones. The risks from cross-sex hormones are even more serious, and include venous thromboembolism (blood clots), hyperkalemia (high potassium), hypertriglyceridemia (high level of fats in blood), polycythemia (high red blood cell count), hyperprolactinemia (high prolactin hormone levels), decreased HCL cholesterol and increased LDL cholesterol, hypertension (high blood pressure), cardiovascular disease, cerebrovascular disease, meningioma (brain tumor), polyuria (excessive urine production), dehydration, cholelithiasis (gallstones), type 2 diabetes, low bone mass, osteoporosis, weight gain, acne, sleep apnea, androgenic alopecia (hair loss), erectile dysfunction, and infertility.7
And this is just the list of possible effects of hormonal treatment. Surgical interventions can bring a host of new adverse effects, depending on the type of surgery. For example, there are numerous reports of hair painfully growing within the neo-vaginal lining follow a vaginoplasty, urination complications following a phalloplasty, and even fatal sepsis following a mastectomy. Most forms of bottoms surgery are guaranteed to lead to infertility: how can someone father a child if their testicles have been removed or conceive a baby of their uterus is gone?
Those are the risks for what is supposed to be gender-affirming care. But are there any benefits?
While some studies document improved mental health outcomes after hormonal or surgical interventions,8 these studies only report on short-term outcomes. Much more valuable studies, known as longitudinal studies, track outcomes over long periods of time. The best longitudinal study, headed by Swedish researcher Cecilia Dhejne, found that health outcomes deteriorate just one year after undergoing a surgical transition. By the fifth year after surgery, patients had poorer outcomes in seven of eight measured categories: mental health, vitality, bodily pain, social function, emotional functioning, physical functioning, and general health.9
“Gender-affirming care” is a misnomer.
It’s not caring at all.
These are only some of the harms of medical gender transitioning. And this is why “gender-affirming care” is a misnomer. It’s not caring at all. It ignores our biological identity as a male or a female, and so perhaps it isn’t all that surprising that there are all of these negative effects of medical or surgical transitioning.
So, what counts as success when treating gender dysphoria? All sides in this debate should agree that, at a minimum, the loss of fertility and increased risk of a host of serious medical conditions, are not signs of success. Yet, these are the results of medical transitioning far too often.
Defining success as improved life satisfaction and decreased risk of suicidality and self-harm is a good step in the right direction, but even on this score, the long-term data on these measures of success do not favour medical transitioning.
