Diagnosing disorders of sex development involves a comprehensive evaluation of the child’s physical characteristics, genetic makeup, and hormone levels. Diagnostic steps include:

• Physical examination: The doctor will examine the genitalia and reproductive organs to assess any atypical features.

Lab Tests

• Genetic Testing:
  • Chromosome Analysis: Basic genetic test to identify if a chromosomal anomaly is causing the condition.
  • Advanced Genetic Testing: Includes techniques like FISH (to check specific Y chromosome regions), array-CGH (to identify small gene deletions or duplications), and other sequencing tests. These are optional and based on initial findings, family choice, and availability.
• Hormone Screening:
  • Measures hormone and electrolyte levels right after birth to rule out salt-wasting CAH.
  • Commonly checked hormones include 17-hydroxyprogesterone, cortisol, testosterone, and others, ideally tested after the first few days when levels normalize.
  • hCG Stimulation Test: Helps to assess the function of gonadal tissue when needed. This test is generally skipped during the natural hormone surge in the first few months of life.

Imaging Studies

• Ultrasound (US):
  • Pelvic US: To view the structure of internal organs, like the presence of müllerian structures, and assess any nonpalpable gonads.
  • Kidney and Bladder US: Checks for common congenital issues in the urinary tract associated with DSDs.
• Genitography:
  • Used to understand the internal duct anatomy by injecting contrast into the urogenital area.
  • Can help identify specific features, like whether there’s a common urogenital sinus or other anatomy variations.
• MRI: Typically, not required but can clarify the internal structure and detect any additional issues, such as spinal problems. Its use may be limited due to cost and the need for anesthesia.

Additional Tests

• Endoscopy: Performed either before or during surgery, it helps visualize the urogenital structures to plan corrective procedures effectively.

Surgical Procedures

• Laparoscopy:
  • Used to view and biopsy internal gonads, minimizing the need for open surgery.
  • Helps provide a full picture of internal anatomy while reducing recovery time and risks.

Treatment for disorders of sex development varies depending on the specific condition and the needs of the child. At Gertrude’s Children’s Hospital, we offer a multidisciplinary approach to managing DSD, involving specialists in endocrinology, urology, genetics, and psychology:

Key Factors in Treatment Planning

When planning treatment for a child with DSD, doctors consider several factors:

• The physical appearance (phenotype) and function of external and internal genitalia
• The risk of tumors in the gonads (ovaries or testes)
• Potential for fertility
• Psychosocial factors, including gender identity

Many health organizations provide guidelines to help manage DSDs, including recommendations on gender assignment and whether surgery should be done early or delayed until the individual can decide.

• Gender Assignment

• • • Assigning a gender in DSD cases can be challenging because anatomy may not clearly indicate future gender identity. For example:
      • 46,XX individuals (typically females with over-virilization): Gender is usually assigned female, as they have normal ovaries and reproductive organs.
      • 46,XY individuals: Gender assignment is more complex and depends on factors like genital anatomy, androgen sensitivity, and future fertility potential.

• Medical Therapy

• • • Treatment depends on the underlying cause. For example:
      • Hormone Replacement: If the body doesn’t produce necessary hormones, treatment with estrogen or testosterone may be prescribed, especially if gonads are removed or hormone production doesn’t match the assigned gender.

• Surgical Options

• Timing and Controversy

• • • • Surgical decisions, particularly for genital reconstruction, are complex:
        • Early Surgery: Some support early surgery to create a more typical anatomy, which can be easier technically and potentially reduce psychological stress for the family.
        • Delayed Surgery: Others recommend waiting until the individual can make their own decision, as this approach may better align with their preferences in adulthood.

• Types of Surgery

• • • • For Virilized Females (46,XX): Feminizing genitoplasty may include separating the urethra and vagina, vaginoplasty, and clitoroplasty. Timing is decided together with the family.
      • For Undervirilized Males (46,XY): Typically involves procedures like hypospadias repair or orchiopexy (if testes are undescended).

• Gonadectomy (Removal of Gonads)

• • • • Gonadectomy may be advised if there’s a high risk of cancer or if hormone production conflicts with the chosen gender. 
      • Careful consideration and monitoring are important, especially if the risk of malignancy is high. 
      • For individuals retaining gonads, regular screening is essential to detect any signs of malignancy early.

• Counseling and psychological support:
  Children and families dealing with DSD may benefit from psychological counseling to help manage the emotional aspects of the condition. Our team provides resources and support to promote understanding, acceptance, and mental well-being.
• Fertility preservation:
  In cases where future fertility may be affected, options for fertility preservation may be discussed with families. This may include storing reproductive cells or tissues, depending on the specific condition and the child’s needs.

Long-term follow-up:
Regular follow-up visits are essential to monitor hormone levels, growth, and development. Our team will work with you to adjust treatment as your child grows and provide support throughout their life.
