Yes, individuals with androgen insensitivity syndrome (AIS) do produce testosterone, but it does not have an effect on their bodies. AIS is a genetic condition in which the body’s cells are unable to respond to androgens, which are hormones that are important for the development of male characteristics. As a result, individuals with AIS have some or all of the physical characteristics of a female, including a uterus and fallopian tubes, but they have XY chromosomes (male chromosomes).
Testosterone is an androgen, and individuals with AIS produce testosterone in their bodies just like any other male. However, the testosterone does not have an effect because their bodies are unable to respond to it. Instead, other hormones, such as estrogen, control their development.
In some cases, individuals with AIS may be treated with testosterone to help them develop more male characteristics. For example, testosterone may be used to increase muscle mass or facial hair growth, or to reduce breast size. However, this form of treatment is usually only recommended if the individual has a strong desire to have more male characteristics.
