How common is this condition called 'Atypical Genitalia'?
This is a very rare condition . According to statistics, only one in 1,000 to 4,500 newborns is affected by this condition. So, although it is very unheard of, it is important to be aware of this.How do a baby's genitals normally develop?
To understand this, you need to know a little about how a baby's sex organs develop in the womb. Imagine, this is a very complex and amazing process. This happens in three main steps: 1. Genetic sex determination: The first thing that happens is that the baby's genetic sex is determined. This happens when a sperm from the father unites with an egg from the mother. The mother always receives an X chromosome. The father can receive either an X or a Y chromosome. So, if an X from the mother and an X from the father combine (XX), a girl is born. If an X from the mother and an Y from the father combine (XY), a boy is born. 2. Gonad formation: Next, the baby's gonads develop according to this genetic sex. In a female baby, the ovaries develop, and in a male baby, the testes develop. 3. Development of internal and external genitalia: Finally, the hormones produced by these gonads are responsible for the development of the baby's internal genitalia and external genitalia. So, if there is a change in any part of this process, then a condition called Dissociative Developmental Disorder (DSD), or 'Atypical Genitalia', can occur. Most often, this is due to hormonal problems. These hormonal influences can be passed on through genes from parents, or they can occur for no apparent reason.What are the causes of 'Atypical Genitalia'?
Most of the time, the main reason for this is hormonal irregularities that occur in the baby's body during pregnancy.These hormones control the development of the baby's sex organs. So, if there is an imbalance in these hormones, it will affect the way the baby's sex organs develop. These reasons may vary depending on the baby's sex chromosomes.46 XX DSD (DSD with female chromosome pattern)
In this condition, the baby's genetic makeup is female (XX). This means that the baby has ovaries and a uterus inside. However, the external genitalia may look like a male, with a penis and testicles. This happens if the baby's external genitalia are exposed to increased levels of male hormones (androgens) during the development of the baby's external genitalia. The most common cause of this is a condition called 'Congenital Adrenal Hyperplasia' (CAH). This is when the baby's adrenal glands produce too many male hormones.46 XY DSD (DSD with male chromosome pattern)
In this case, the baby's genetic makeup is male (XY). This means that the baby should have testicles (testes) inside. However, the external genitalia do not show clearly male characteristics, and may even resemble female characteristics. There are several main reasons for this:- The baby's testicles are not developing properly.
- The testicles fail to produce enough of the male hormone testosterone.
- Even though testosterone is produced, the baby's body is unable to use it properly.
Disorders of Gonadal Differentiation
What happens in this case is that the baby's gonads do not fully develop into either testes or ovaries.- Mixed Gonadal Dysgenesis: In this, the gonads (testes or ovaries ) are not fully developed.
- Partial Gonadal Dysgenesis: In this, although some testicular tissue has formed in the baby's gonads, those testicles do not function properly.
- Gonadal Dysgenesis: In this, both gonads are premature, meaning they do not develop into either testicles or ovaries.
Ovotesticular DSD (ovum-testicular DSD)
This is a very rare condition. In this case, the baby's gonads may contain both ovarian tissue and testicular tissue. Or, there may be an ovary on one side and a testicle on the other.What does the condition 'Atypical Genitalia' look like externally?
The appearance of this condition varies depending on the affected chromosomes and hormonal status. Atypical genitalia in a genetically female (XX chromosomes) baby may have the following features:- The clitoris becomes enlarged and looks like a small penis.
- The urethral opening is located below the scrotum or inside the vagina instead of its normal location.
- The labia are stuck together, looking like a scrotum.
- There may be a lump of tissue between the labia, which may look like a pouch containing the testicles.
- The penis is completely absent or very small, looking like an enlarged penis (micropenis).
- The urethral opening is located at the base of the penis or between the scrotum instead of at the tip (this condition is also called 'Hypospadias').
- The scrotum is shrunken, split in two, and looks like the labia.
- The testicles have descended from the abdominal cavity and are no longer in the scrotum ( undescended testicles ).
What are other symptoms of 'Atypical Genitalia'?
The appearance of the external genitalia is the main characteristic. In addition, you may see things like:- Hormonal imbalances.
- In the case of a girl, menstruation may start very early, be late, or not occur at all.
- Hypospadias is when the urethral opening is not located at the tip of the penis.
How do doctors diagnose this condition?
Doctors often diagnose this condition as soon as a baby is born . Or, during the baby's first well-child exam. If it is not clear whether the baby is a boy or a girl, the baby's doctor will order several more tests.What to expect during your child's medical checkup?
The doctor will first ask you about your family medical history. Then, he or she will carefully examine the baby's external genitalia. The following tests may be performed to make an accurate diagnosis:- Blood tests: To check the baby's hormone levels and chromosomes.
- Imaging tests: These can look at the baby's internal genitalia, such as an ultrasound, X-ray, or MRI (Magnetic Resonance Imaging) scan.
- Biopsy or Laparoscopy: To take a small piece of tissue from the baby's gonads for examination.
How is 'Atypical Genitalia' treated?
Before starting treatment, the first step is to find out the exact cause of this condition. Then, based on the results of hormone tests and other tests, the medical team will decide on a treatment plan and the appropriate sex assignment for the baby. Since this is a very complex and sensitive matter, a multidisciplinary team will be there to help you. It is very important to find people who have expertise in these types of conditions. They will be the ones who can give you the best advice. This team may include specialists such as:- Neonatologist
- Geneticist
- Endocrinologist
- Surgeon
- Urologist
- Psychologist
- The reason for the baby's condition.
- The appearance of the baby's genitals.
- Your family's wishes and cultural beliefs.
- Hormone Replacement Therapy (HRT): If there is a hormonal imbalance, this condition can be controlled with hormone therapy alone.
- Reconstructive surgery: Sometimes, the medical team may discuss with you and suggest surgery while your baby is still young. However, there are different opinions about this reconstructive surgery for 'Atypical Genitalia'. Sometimes, for example, if the baby does not have an opening for urine to pass through, surgery is medically necessary. However, if the surgery is mainly to improve appearance, some parents choose to wait until the baby is older and can make decisions about their own body. This is a very important and well-thought-out decision.
Remember: This surgical decision can have a big impact on your child's future life, so it's a good idea to talk to a counselor who has expertise in this field.
If my child has 'Atypical Genitalia', what should I expect?
The condition 'Atypical Genitalia' has profound effects on the child not only physically, but also socially and psychologically.It can be caused by the nature of the genitals, which can affect a child's sense of self. The decision to have surgery can affect a child's quality of life. This is why it is important to seek expert advice about this. Although a diagnosis of 'Atypical Genitalia' can be very distressing, your medical team will help you decide on the best course of treatment.When should I seek medical advice about my child's 'Atypical Genitalia' condition?
The doctor usually diagnoses this condition at birth or during the baby's first medical examination. The doctor will then discuss the diagnosis and treatment options with you.What questions should I ask my child's doctor?
At a time like this, you may have many questions on your mind. These questions may help you:- Does my child need treatment right away, or can we wait a little longer and make a decision later?
- Which specialists should my child see?
- Should we see a genetic counselor?
- What will my child's future be like?
- Are there support groups for people and families with 'Atypical Genitalia'?
Will my child be able to have children in the future?
