It depends on how you define gender dysphoria and transsexuality.
Gender dysphoria is a condition where a person experiences discomfort or distress because there is a mismatch between their biological sex and their gender identity. Transsexuality is a condition where a person identifies as a different gender to their biological sex.
There is no single cause of gender dysphoria or transsexuality. It is thought to be a combination of biological and environmental factors.
Some people with gender dysphoria may not identify as transsexual. They may simply experience discomfort or distress due to the mismatch between their biological sex and gender identity. For others, the mismatch is so strong that they identify as a different gender altogether. This is known as transsexuality.
There is no one 'right' way to deal with gender dysphoria or transsexuality. Some people may choose to live in their preferred gender role without undergoing any medical interventions. Others may choose to undergo hormone therapy and/or sex reassignment surgery in order to physically align their bodies with their gender identity.
There is no 'cure' for gender dysphoria or transsexuality. However, with support, understanding and acceptance, many people are able to lead happy and fulfilling lives.
