If your baby has been diagnosed with or you suspect has labial adhesion, here is what the evidence says.

The short answer

Labial adhesion (also called labial fusion) is when the inner labia stick together, partially or completely covering the vaginal opening. It's common in baby girls and toddlers, affecting about 2% of girls. Most cases don't cause symptoms and resolve on their own as your child grows. Treatment with estrogen cream is effective if needed, and surgery is rarely necessary.

Fever itself is not an illness — rather, it is a sign or symptom that the body is fighting an infection. Fever stimulates certain defenses, such as the white blood cells, which attack and destroy invading bacteria.

What Parents Should Know

According to AAP guidelines, labial adhesion (also called labial fusion) is when the inner labia stick together, partially or completely covering the vaginal opening. It's common in baby girls and toddlers, affecting about 2% of girls. Most cases don't cause symptoms and resolve on their own as your child grows. Treatment with estrogen cream is effective if needed, and surgery is rarely necessary. At 0-6 months, labial adhesion is less common in young infants but can occur. You may notice during diaper changes that the labia appear to be stuck together with a thin membrane. Most don't cause any symptoms. Your pediatrician will examine your baby and determine if treatment is needed. If your baby can urinate normally and has no discomfort, observation alone is often recommended. It is generally considered normal when your baby has a partial labial adhesion that doesn't cause symptoms. However, you should contact your pediatrician promptly if your baby is having significant difficulty urinating or seems in pain when urinating.

Normal vs. Concerning

Usually Normal
Worth Discussing
Your baby has a partial labial adhesion that doesn't cause symptoms
Your baby is having significant difficulty urinating or seems in pain when urinating
Your baby can urinate normally without difficulty or discomfort
Your baby has signs of urinary retention (very swollen lower abdomen, extreme fussiness)

When to Seek Immediate Care

  • Your baby is having significant difficulty urinating or seems in pain when urinating
  • Your baby has signs of urinary retention (very swollen lower abdomen, extreme fussiness)
  • Your baby has signs of urinary tract infection (fever, foul-smelling urine, frequent crying)
  • The area appears very red, swollen, or infected

By Age

What to expect by age

0-6 months

Labial adhesion is less common in young infants but can occur. You may notice during diaper changes that the labia appear to be stuck together with a thin membrane. Most don't cause any symptoms. Your pediatrician will examine your baby and determine if treatment is needed. If your baby can urinate normally and has no discomfort, observation alone is often recommended.

6-18 months

This is a common age for labial adhesion to develop. Low estrogen levels in infancy contribute to the adhesion. If the fusion is partial and your baby has no symptoms, your pediatrician may recommend just monitoring. If the adhesion is causing urinary issues, discomfort, or is very extensive, a short course of estrogen cream applied to the area can help separate the labia.

18 months - 3 years

Labial adhesions are common in toddlers. Most cause no symptoms and are discovered during routine exams. If your child has difficulty urinating, urinary tract infections, or discomfort, treatment with estrogen cream is usually effective. The cream is applied once or twice daily for several weeks. Your pediatrician will monitor progress.

3-5 years

Many labial adhesions resolve spontaneously as your child approaches puberty and natural estrogen levels rise. If adhesion persists and causes symptoms, estrogen cream can still be used. Rarely, manual separation in the doctor's office or very rarely surgery may be considered for severe, symptomatic cases. Most resolve without intervention.

5 years+

As girls approach puberty, rising estrogen levels usually resolve labial adhesions. If adhesion persists into later childhood and causes problems, your pediatrician or a pediatric gynecologist can discuss treatment options. Recurrence after successful treatment is possible but less common as your child gets older.

What to Tell Your Pediatrician

  • Describe when you first noticed has labial adhesion and how it has changed over time.
  • Note your baby's current age and which age-specific patterns you are seeing.
  • Mention if you've noticed the labia appear stuck together and want it evaluated.
  • Mention if your baby seems to have difficulty urinating or the stream is unusual.
  • Bring a list of any questions or observations you want to discuss at the appointment.

What Should You Do?

When to take action

Probably normal when...
  • Your baby has a partial labial adhesion that doesn't cause symptoms

My Baby's Head Shape Looks Abnormal

Many babies develop temporary head shape irregularities that are completely normal. A cone-shaped head from vaginal delivery reshapes within days. Mild positional flattening (plagiocephaly) from sleeping on the back is very common and usually improves with repositioning and tummy time. However, head shape changes involving ridges, a persistently bulging fontanelle, or rapid head growth changes should be evaluated to rule out craniosynostosis.

Achondroplasia (Dwarfism) in Babies

Achondroplasia is the most common form of short-limbed dwarfism, affecting about 1 in 15,000 to 40,000 births. It is caused by a mutation in the FGFR3 gene and is usually apparent at birth with characteristic features including short limbs, a larger head, and a prominent forehead. Intelligence is normal. With monitoring for specific complications and supportive care, children with achondroplasia lead full, active, and independent lives.

Adenoid Hypertrophy and Breathing

Adenoids are lymphoid tissue located behind the nose that help fight infection in young children. When adenoids become enlarged (adenoid hypertrophy), they can block the nasal airway, causing chronic mouth breathing, snoring, nasal speech, and sleep-disordered breathing. Enlarged adenoids are most common between ages 2-7 and are a leading cause of obstructive sleep apnea in young children. Treatment ranges from watchful waiting and nasal steroids to surgical removal (adenoidectomy) if breathing or sleep is significantly affected.

Adrenoleukodystrophy (ALD) in Babies

X-linked adrenoleukodystrophy (X-ALD) is a genetic disorder affecting about 1 in 17,000 newborns, caused by mutations in the ABCD1 gene on the X chromosome. It primarily affects boys and impairs the breakdown of very long-chain fatty acids (VLCFAs), which accumulate and damage the myelin sheath in the brain and the adrenal glands. The most severe form, cerebral ALD, typically affects boys between ages 4-10 with rapid neurological decline. Newborn screening now enables early detection, and hematopoietic stem cell transplant or gene therapy performed before significant brain involvement can be life-saving.

How to Advocate for Your Child's Needs

You know your child better than anyone, and your observations matter. If you feel something is not right with your child's development or health, you have every right to ask questions, request evaluations, and seek second opinions. Advocating for your child is not being difficult - it is being a good parent.

Agenesis of the Corpus Callosum (ACC)

Agenesis of the corpus callosum (ACC) is a condition in which the corpus callosum — the bundle of nerve fibers connecting the left and right hemispheres of the brain — fails to develop partially or completely. It occurs in approximately 1 in 4,000 births and is one of the most common brain malformations. ACC can be detected on prenatal ultrasound or postnatal MRI. Outcomes vary enormously: some individuals with isolated ACC have normal intelligence and minimal difficulties, while others (especially when ACC occurs alongside other brain abnormalities or genetic syndromes) may have significant developmental delays. The variability means that prenatal counseling and postnatal monitoring are both essential.
