Imagine your 12-year-old daughter announcing she’s actually a boy, or your son insisting he’s trapped in the wrong body. Online influencers promise you that medical transition will solve everything. School counselors urge you to use new pronouns and a new name for your child, warning that rejection of the practice could lead to the kid’s suicide. You’re told you must choose: a transitioned child or a dead one.
But what if this is a false choice? And what if both Jewish law and the best available science point to a very different path?
To address questions such as these, the Coalition for Jewish Values and Do No Harm have jointly released a groundbreaking guide for rabbis, Jewish educators and parents facing one of the most challenging issues of our time: How to respond when a child expresses gender dysphoria. This comprehensive resource, “Rethinking Gender Affirmation,” offers what has been sorely missing from public discourse—a careful examination of both Jewish tradition and scientific evidence regarding the social, medical and surgical transition of children.
In an era when the internet and social media expose our children to countless influences beyond parental control, gender ideology has become particularly pervasive. It preaches that gender exists on a spectrum and that children can be born in the “wrong” body. For adolescents already navigating the awkwardness of puberty, this message can fuel profound confusion—what is known as “gender dysphoria” or, more aptly, “sex identity disorder.”
The mental anguish these children experience is real and demands our compassion. However, compassion does not mean endorsing every proposed solution.
The guide makes clear that so-called “gender-affirming care”—social transition through cross-dressing and name/pronoun changes; medical transition via puberty blockers and hormones; and surgical transition involving the removal or alteration of healthy body parts—causes more harm than good. These interventions frequently lead to lifelong sexual dysfunction, sterility and numerous other serious health consequences, in addition to violating numerous halachic (Jewish law) prohibitions.
The Jewish perspective
At the heart of Jewish teaching stands a fundamental truth: “God created man in His image; in the image of God He created him; male and female He created them.” This binary understanding of sex is not merely descriptive; it is foundational to Jewish ethics and identity.
The late Rabbi Lord Jonathan Sacks observed that sexual ethics—grounded in the sanctity of marriage between man and woman—is what distinguished ancient Israel from pagan societies, and what continues to distinguish Judaism from secular ideologies today.
The sign of the covenant itself, circumcision, connects holiness intimately with sexuality. As Rabbi Joseph Soloveitchik explained, man and woman represent not just biological differences, but “two ideas of personality”—distinct yet complementary, each essential to the other’s completeness.
Contrary to The New York Times and self-declared Talmud experts on social media, claims that Jewish law recognizes multiple genders beyond male and female are simply false. While the Talmud discusses eunuchs and rare disorders of sex development—cases where an individual’s primary or secondary sex characteristics fail to develop normally, or physical abnormalities obscure someone’s sex—these discussions never suggest that sex is a spectrum or that people can change their gender.
A man who is castrated (saris) is still a male, and a woman who is sterile or experiencing a disorder of sexual development, such as Turner’s Syndrome (aylonis), is still a female. The “tumtum” (a Hebrew word in Jewish texts for a person whose sex is unclear) for and “androgynous” classifications address biological ambiguity, not internal feelings about one’s body. These categories are not separate genders from male or female.
Gender transition—whether social, medical or surgical—violates numerous Jewish prohibitions. Surgical removal of reproductive organs transgresses the explicit biblical prohibition against castration. Cross-dressing violates the commandment: “A man’s attire shall not be on a woman, nor may a man wear a woman’s garment.”
Even hormone treatments that alter sexual characteristics may run afoul of these laws. Numerous other halachic requirements and prohibitions may be violated, including, but not limited to: the prohibition against unnecessary injury; the obligation to be fruitful and multiply; the prohibition against putting a stumbling block before the blind; and the obligation of “you shall be holy.”
Some argue that saving a life (pikuach nefesh) overrides these prohibitions. But rabbinic authorities have consistently concluded that mental anguish, however genuine, does not suspend Torah law in this context. Moreover, the premise itself is flawed, as there is no reliable evidence that transition prevents suicide or improves long-term mental health.
What the science shows
The guide reviews systematic evidence from multiple countries that have examined gender-affirming care. The “Cass Review” in the United Kingdom, along with similar evaluations in Sweden, Finland, Norway and France, reached the same sobering conclusion: that there is no reliable, objective evidence that social transition, puberty blockers or cross-sex hormones benefit children with gender dysphoria.
Even more striking: Studies show that when gender identity is not affirmed and social transition does not occur, between 61%-98% of gender-dysphoric children outgrow their dysphoria by adulthood. Without intervention, the vast majority become healthy adults. However, 96% of children who undergo social transition continue to medical transition, with its cascade of serious complications.
The harms are substantial and well-documented. Puberty blockers prevent normal physical and neurological development, cause bone density loss and risk permanent infertility. Cross-sex hormones in females can cause vaginal atrophy, cardiovascular disease and diabetes. In males, they cause testicular degeneration, erectile dysfunction and increased stroke risk. Surgical interventions create lifelong complications, with complication rates as high as 76.5%.
A compassionate path forward
Parents facing a child’s gender distress deserve better than false promises and ideological pressure. They need honest information about the risks, the lack of evidence for benefits and the reality that most children naturally resolve these feelings without medical intervention.
Jewish tradition, informed by rigorous science, offers a wiser path: patience and proper psychological care for underlying issues. This is not rejection; it is genuine care for our children’s long-term physical, mental and spiritual wellbeing.
The guide from the Coalition for Jewish Values and Do No Harm provides families with the knowledge they need to resist pressure for unnecessary, untested and dangerous medical interventions and make truly informed decisions. In protecting our children from experimental and harmful treatments, we honor both the wisdom of our tradition and the findings of sound science.
