Do People With Androgen Insensitivity Syndrome Produce Sperm?

No, individuals with Androgen Insensitivity Syndrome (AIS) generally do not produce functional sperm, or they produce extremely little to none at all. This means they are typically infertile in terms of biological fatherhood.

Understanding Androgen Insensitivity Syndrome (AIS)

Androgen Insensitivity Syndrome is a genetic condition that affects how a person's body responds to androgens, which are male hormones like testosterone. While individuals with AIS are genetically male (they have XY chromosomes), their bodies cannot effectively use these hormones. This can lead to a range of physical characteristics that vary depending on the degree of insensitivity.

AIS exists on a spectrum, primarily categorized into:

• Complete Androgen Insensitivity Syndrome (CAIS): Individuals with CAIS have testes internally, but their bodies are entirely unresponsive to androgens, leading to external female characteristics.
• Partial Androgen Insensitivity Syndrome (PAIS): In PAIS, there is a partial response to androgens, resulting in a range of characteristics that can be predominantly male, predominantly female, or ambiguous.

For more detailed information on the condition, you can refer to resources from the National Health Service (NHS).

How AIS Affects Sperm Production

Despite having testes (which are typically located internally and produce androgens), the cellular resistance to these hormones in individuals with AIS prevents the normal development of the male reproductive tract and the process of spermatogenesis—the creation of sperm.

Specifically, those with Partial Androgen Insensitivity Syndrome (PAIS) may produce no sperm or very little sperm. It's also important to note that, similar to individuals with Complete Androgen Insensitivity Syndrome (CAIS), people with PAIS do not develop a womb or ovaries, which are female reproductive organs. The inability of the body to respond to androgens effectively disrupts the complex hormonal signals and structural developments required for functional sperm production.

Fertility and AIS

Due to the lack of functional sperm production, individuals with AIS are considered infertile, meaning they cannot biologically father children. Reproductive options for starting a family may include adoption or other forms of assisted reproduction that do not rely on their own sperm.
