Atypical genitalia

Diagnosis

Atypical genitalia is usually diagnosed at birth or shortly after. Sometimes, healthcare professionals may suspect atypical genitalia during pregnancy when results of blood tests of the unborn baby's sex differ from the ultrasound imaging of the baby's genitalia. But generally, the diagnosis is not made until after birth. Healthcare professionals who help with delivery may notice the signs of atypical genitalia in your newborn.

Determining the cause

If your baby is born with atypical genitalia, your doctor and other healthcare professionals work to find the cause. The cause helps guide treatment and decisions about your baby's sex. Your healthcare professional begins by asking questions about your family and medical history. Your baby has a physical exam to check for testicles and evaluate the genitalia.

Your baby will likely have these tests:

• Blood tests to measure hormone levels.
• Blood tests to look at chromosomes. This can show the genetic sex: typically, XX or XY. These blood tests also can show conditions caused by a gene change that affects sex organ development.
• Ultrasound of the pelvis and belly to look for testicles that haven't descended, a uterus or a vagina.
• X-ray studies using a contrast dye to help give a clear picture of pelvic and belly structures.

Sometimes minimally invasive surgery is needed to collect a tissue sample of your newborn's reproductive organs. This surgery is done through one or more small cuts using tiny cameras and surgical tools.

Deciding the sex

Using the information gathered from these tests, your healthcare professional may suggest a sex for your baby. The suggestion is based on the cause, genetic sex, anatomy, future reproductive and sexual potential, probable adult gender identity, and discussion with you.

Sometimes, a family may make a decision within a few days after the birth. But it's important that families wait until tests are finished. Sex assignment can be complex and delayed. Parents should be aware that as the child grows up, the child may make a different decision about gender identification.

Treatment

The goal of treatment is long-term mental health and social well-being, as well as having as much sexual function and fertility as possible. When to begin treatment depends on your child's specific situation.

Atypical genitalia is complex and not common. Managing it may require a team of experts. The team might include:

• Pediatricians.
• Experts in newborns born early or with medical conditions, also called neonatologists.
• Experts in children's urinary systems, also called pediatric urologists.
• Pediatric general surgeons.
• Experts in the body's hormones, also called endocrinologists.
• Medical geneticists.
• Mental health professionals, such as psychologists or social workers.

Medicines

Hormone medicines may help correct or manage hormones that are out of balance. For example, in a genetic female with a slightly enlarged clitoris caused by mild congenital adrenal hyperplasia, hormone replacement maybe the only treatment needed.

Surgery

In children with atypical genitalia, surgery may be used to:

• Keep healthy sexual function.
• Create genitals that appear more typical.

The timing of surgery depends on your child's specific situation. Some healthcare professionals prefer to postpone surgery done only for appearance. They suggest waiting until the person with atypical genitalia is mature enough to be part of the decision about sex assignment.

For children with atypical genitalia, the sex organs may work properly in spite of how the genitals look on the outside. For girls, if the vagina is hidden under the skin, for example, surgery in childhood can help with sexual function later. For boys, surgery to reconstruct a partially developed penis may create a more typical appearance and make erections possible. Surgery to move the testicles into the scrotum may be needed.

Results of surgery are often satisfying. But repeat surgeries may be needed. Risks include a disappointing appearance or problems with sexual function, such as trouble reaching an orgasm.

Ongoing care

Children with atypical genitalia need ongoing medical care. This includes watching for complications, such as getting cancer screenings into adulthood.

Coping and support

If your baby has atypical genitalia, you may worry about the baby's future. Mental health professionals can help you deal with this difference that you didn't expect. Ask your child's healthcare professional for a referral to a mental health professional who has experience helping people in your situation. You also may find it helpful to join a support group, either in person or online.

Your child may find ongoing counseling by mental health professionals helpful and may choose to be a part of support groups into adulthood.

Not knowing the sex of your newborn right away might turn a hoped-for celebration into a stressful time. Your medical team can provide you with updates and information as quickly as possible. They also can answer questions and talk with you about your child's health.

Consider waiting to make a formal announcement of the birth until testing is done and you've created a plan with advice from your medical team. Give yourself some time to learn and think about your child's condition before answering questions from family and friends.

Preparing for your appointment

If your baby is born with atypical genitalia, you may be referred to a medical center with doctors and other healthcare professionals who have expertise in managing this condition. Here's some information to help you get ready for your appointment and learn what to expect.

What you can do

Before your appointment:

• Ask if there's anything you need to do to prepare your baby for tests and procedures.
• Discuss family history with your blood relatives, such as parents, grandparents and cousins, and bring key personal information, including family history of genetic conditions, such as atypical genitalia.
• Consider taking a family member or friend along. Sometimes it can be hard to remember all the information given during an appointment. Someone who goes with you may remember something that you missed or forgot.
• Make a list of questions to ask your healthcare professional.

Questions to ask may include:

• What caused my baby's atypical genitalia?
• What genetic testing has been done?
• What other tests might my baby need?
• What is the best treatment plan?
• What are other options to the primary treatment that you're suggesting?
• Is there a generic option to the medicine you're prescribing?
• Are there any special instructions that I need to follow?
• Should my baby see any other specialists?
• What options are there for counseling and support for our family?
• Do you have any printed material that can help me learn more? What websites do you suggest?

Feel free to ask other questions during your appointment.

What to expect from your doctor

Your healthcare professional is likely to ask you questions, such as:

• Does your family have a history of atypical genitalia?
• Does your family have a history of genetic conditions?
• Do any health conditions tend to run in your family?
• Have you ever had a miscarriage?
• Have you ever had a child who died in infancy?

Be ready to answer questions so that you have time to talk about what's most important to you.
