When a fetus grows in the womb, sometimes little things don't go as expected. Some children may have minor problems with their genitals when they are born. Or, their bodies may not change as expected when they reach puberty. At such times, we can think of a condition called `(Androgen Insensitivity Syndrome)`. Don't worry, we will talk about this simply, in a way that you can understand.
What is Androgen Insensitivity Syndrome?
Simply put, Androgen Insensitivity Syndrome (AIS) is a condition in which a child is genetically male (i.e., has an X chromosome and a Y chromosome), but his body does not respond properly to the male sex hormones, androgens . Think of it this way: there are little gates in our bodies that send messages to the cells, and they respond to these hormones. In a person with AIS, these gates do not work properly.
Doctors call this a disorder of sex differentiation . It used to be called testicular feminization syndrome, but that name is no longer used. This condition affects the way a baby's sex organs develop while they are still in the womb. It also affects the development of sexual characteristics that should occur during puberty. Often, people with this condition are unable to have children as adults (infertility) .
Are there different types of this?
Yes, there are three main types of `AIS`. Each type has slightly different characteristics.
1. Complete Androgen Insensitivity Syndrome (CAIS):
- These people look completely like girls on the outside. That is, their genitals look like those of a girl.
- However, they do not have female internal genitalia (i.e. ovaries, fallopian tubes, uterus).
- Most of the time, people with `CAIS` are raised as girls.
2. Partial Androgen Insensitivity Syndrome (PAIS):
- Their external genitalia may not be fully developed like a boy's, or they may look like a girl's, or they may have a mixture of both, making it difficult to clearly identify them as male or female (ambiguous genitalia).
- People with `PAIS` are sometimes raised as boys and sometimes as girls.
3. Mild Androgen Insensitivity Syndrome (MAIS):
- Their genitals look like those of a male child.
- However, they are also usually unable to have children (infertility). Some doctors consider `MAIS` to be a part of `PAIS` itself.
Who can develop this condition? How common is it?
This `AIS` condition is caused by a defect in the `Androgen Receptor (AR) gene` , which is on the `X` chromosome that is passed from the mother to the child. Since this is an `X-linked` gene, if the mother is a carrier of this defective gene, her male child has a 1 in 4 chance of developing this `AIS` condition. Female children can also inherit this defective gene, and then they will also be carriers, but they will not develop `AIS`.
AIS is a very rare condition . PAIS affects about one in 99,000 male babies. CAIS affects between two and five in 100,000 babies.
Why is this happening? What is the reason?
As we mentioned earlier, the main reason for this is an abnormality in the `AR` gene on the `X` chromosome. When this gene doesn't work properly, the body can't make androgen receptors. These androgen receptors are, simply put, the things that help the body's cells respond to male hormones called androgens (for example , testosterone) . So, when these receptors are missing, the body doesn't "recognize" the male hormones, which means that even if those hormones are present, they don't do what they're supposed to do.
What are the symptoms of this?
The symptoms of AIS vary depending on the type. However, the main feature common to all types is infertility .
People with `CAIS` cannot get pregnant or get their partner pregnant. Although their genitals look like those of a woman, they do not have internal female reproductive organs. People with `PAIS` or `MAIS` are also very unlikely to be able to have children. They may have a very small penis, and sperm production may be very low or absent.
Other symptoms that people with CAIS may experience include:
- Becoming unusually taller than the average girl during puberty.
- Absence of menstruation (Amenorrhea) .
- During puberty , there is very little or no hair in the armpits and genital area.
- Narrowing or shallowness of the vagina .
- The testicles remain in the abdominal cavity (not descended).
Other symptoms that people with PAIS may experience include:
- Bifid scrotum is a condition where the testicle is divided into two .
- Enlargement of the clitoris (Clitoromegaly) .
- Enlargement of breast tissue in boys (Gynecomastia) .
- Hypospadias is when the urethral opening is located on the underside of the penis, not the tip .
- Labial adhesions .
- Abnormally small penis (Micropenis) .
- Partial undescended testicles .
Other symptoms that people with `MAIS` may experience:
- Breast enlargement `(Gynecomastia)` .
- Small penis (Micropenis) .
- Having very little body hair .
How do you recognize this?
A doctor can detect PAIS at birth by looking at the baby's genitals. However, if the baby has CAIS or MAIS, it may not be detected until the child is about 11 or 12 years old, when the baby is in puberty . This is when a doctor can tell if there is a problem.
For example, a child with CAIS may not have a period or may not have pubic hair. A child with MAIS may have a very small penis or may develop breasts. During puberty, undescended testicles can herniate through a weak spot in the abdominal wall. Sometimes, doctors discover that a child has undescended testicles when they have surgery for an inguinal hernia .
What kind of tests are done?
To confirm this `AIS` condition, the doctor will need to perform several tests:
- Blood tests: These check hormone levels , sex chromosomes, and genetic abnormalities .
- Imaging tests: Tests such as ultrasound can confirm whether the female reproductive organs have formed.
If someone in your family has had AIS, and you are planning to have children, it is a good idea to get genetic testing . This test can tell you whether you are a carrier of this abnormal gene.
What are the treatments for this?
Treatment for AIS is determined by the sex assigned at birth. Most treatment begins after the child reaches puberty. This allows time for the child's body to undergo developmental changes and allows the child to be more involved in their treatment decisions.
However, some health experts believe that some treatments, such as removal of the testicles, should be done before puberty because of the risk of developing a type of cancer called gonadoblastomas in undescended testicles. They also say that other treatments can be done after puberty is complete.
Treatment options for children who are raised as boys:
- Surgery to repair male genitalia. For example, `hypospadias repair` (rearranging the urethral opening) or `orchiopexy` (rearranging undescended testicles into the scrotum).
- Breast reduction surgery to remove excess breast tissue.
- Hernia repair surgery is a procedure to close open or weakened tissue in the abdominal wall.
- Testosterone hormone therapy .
Treatment options for children who are adopted as girls:
- Surgery to remove male genitalia or excess clitoral tissue.
- Non-surgical vaginal dilation methods to deepen the vagina.
- Estrogen hormone therapy .
Can this be prevented?
There is no way to prevent AIS. However, if someone in your family has the condition and you are concerned that your child may inherit this abnormal gene, genetic testing can be done to find out if you are a carrier.
How are those living with this condition? (Future Vision)
People with AIS can live full, healthy lives . Many respond well to hormone therapy and surgery. However, because AIS often causes infertility, it can be emotionally difficult for many people. It can also have a profound impact on the mental health of children and young adults.
If you do not have a gonadectomy , your risk of developing testicular cancer increases by about 30%.
If my child has AIS, how can I help?
"Taking care of the child's mental health is a big part of managing AIS."
If your child has AIS, it's important to have a strong support system of understanding doctors, friends, and family. Joining support groups can also help your child share their experiences and challenges with others who are going through the same thing.
As your child enters puberty, and begins to realize that their body is not changing as expected, it is very important to talk to them about AIS .
How do you deal with AIS as an adult?
Living with AIS as an adult can be challenging. It can be difficult to have a normal sex life, find a partner who understands and accepts your condition, and infertility can have a profound psychological impact on many people.
If you have AIS, it can be helpful to talk to a counselor or therapist about your experiences. You can also connect with others who have AIS in support groups.
Finally, things to remember
Androgen Insensitivity Syndrome (AIS) is a condition in which a person is genetically male but does not respond to male hormones. As a result, their genitals may look like those of a woman, or they may have both male and female characteristics. This condition can cause various challenges. Therefore, it is very important for people with AIS to talk to their doctors regularly and get strong psychological support. With proper medical advice and the support of loved ones, these people can also lead successful lives.
