Subtitle: Is Testicular Feminization the Same as Androgen Insensitivity?
Testicular feminization (TF) and androgen insensitivity (AI) are two different conditions that affect the development of male sex characteristics. TF is caused by a mutation in the gene that codes for the androgen receptor, while AI is caused by a mutation in the gene that codes for the enzyme 5-alpha reductase. Although the two conditions share similar symptoms, they are distinct from each other.
Testicular Feminization (TF) is a condition that affects the development of male sex characteristics in males with a genetic mutation in the gene that codes for the androgen receptor. This gene mutation causes the body to be unresponsive to androgens, which are hormones that play a key role in male sexual development. As a result, individuals with TF may have female external genitalia, underdeveloped testes, and absent or incompletely developed male secondary sexual characteristics, such as facial and body hair.
Androgen Insensitivity (AI) is a condition that affects the development of male sex characteristics in males with a genetic mutation in the gene that codes for the enzyme 5-alpha reductase.

Although TF and AI share similar symptoms, they are distinct from each other. TF is caused by a mutation in the gene that codes for the androgen receptor, while AI is caused by a mutation in the gene that codes for the enzyme 5-alpha reductase. Additionally, individuals with TF typically have a more severe form of the condition. For example, individuals with TF may have more severe genital ambiguity, which can lead to complications during puberty and fertility problems. In comparison, individuals with AI typically have fewer complications and a better prognosis.
