20から女性ホルモンやってるけど遅かった
A viral post describes someone starting female hormone therapy at age 20 but feeling it was "too late" because they couldn't achieve their desired physical changes. It's well-known that the effects of hormone therapy for gender transition vary significantly depending on when it starts and individual body types.
This post has sparked a lively online discussion, with many sharing their own experiences, offering empathy and encouragement, and actively exchanging detailed information about treatment outcomes.

Hormone Replacement Therapy (HRT)
Hormone Replacement Therapy (HRT) is a medical treatment involving the administration of external hormones, either to supplement a deficiency of specific hormones in the body or for the purpose of gender transition. For feminizing hormone therapy, estrogen and anti-androgens are primarily used. It is undertaken by individuals with gender dysphoria to align their gender identity with their physical characteristics. Expected effects include softer skin, changes in fat distribution (especially in the hips and chest), breast development, reduction in body hair, and some voice changes (though limited after adulthood). The timing of HRT initiation significantly impacts its effects; starting before puberty can lead to more extensive changes, including skeletal formation. However, starting in adulthood limits skeletal impact, with changes primarily affecting soft tissues (such as fat and muscle). This reality – that desired bodily changes may be less achievable when HRT begins in adulthood – likely underpins the article poster's feeling that it was "too late." HRT also carries several risks, such as thrombosis and liver function impact, requiring careful management under the guidance of a specialist.
Gender Dysphoria
Gender Dysphoria refers to the profound discomfort or distress that arises when an individual's assigned sex at birth does not align with their internal sense of self (gender identity). Formerly known as "Gender Identity Disorder," the diagnostic terminology has evolved in recent years to emphasize "distress caused by incongruence" rather than viewing it primarily as a "mental illness." This incongruence can manifest in various aspects, including physical genitalia, secondary sex characteristics, or societal gender roles. For individuals experiencing gender dysphoria, interventions such as hormone replacement therapy, gender-affirming surgery, or social transition (e.g., changes in clothing, name, gender expression) are vital medical and social supports to alleviate this distress and enable them to live in alignment with their gender identity. The article's poster likely underwent hormone therapy with the wish to alleviate the distress of gender dysphoria and achieve desired physical characteristics. The degree and manifestation of gender dysphoria vary significantly among individuals, requiring diverse forms of treatment and support tailored to each person.
Puberty and Body Formation
During puberty, the human body undergoes significant changes due to the rapid secretion of sex hormones, laying the foundation for physical characteristics that will last throughout life. Specifically, "secondary sex characteristics" emerge, including skeletal growth and formation, voice changes, body hair development, fat distribution, muscle development, and the maturation of genitalia and mammary glands. In males, testosterone drives these changes, while in females, estrogen is the primary driver. Once puberty concludes and the epiphyseal plates close, halting skeletal growth, hormone replacement therapy initiated in adulthood has limited impact on the skeleton itself. For instance, even with feminizing hormone therapy, it is difficult to fundamentally alter pre-formed skeletal structures like broad shoulders or large hands and feet. This is believed to be a contributing factor to the article poster's feeling that it was "too late" when they started hormone therapy at age 20. The common gap between an ideal body image and the changes achievable through adult hormone therapy stems from having passed the "critical period of body formation" during puberty. In recent years, for individuals who experience gender dysphoria at a young age, puberty suppression therapy is being researched and implemented as an approach to temporarily halt unwanted secondary sex characteristics, thereby expanding future gender transition options.
