From the Guidelines
Diagnosis of intersex conditions, also known as Disorders of Sex Development (DSD), involves a comprehensive evaluation. The diagnosis process typically includes a combination of physical examination, hormonal evaluation, and genetic testing, as DSD is defined as a congenital condition associated with atypical chromosomal, gonadal, or anatomical sex 1.
Key Diagnostic Steps
- Initial assessment may include measurement of serum hormone levels and karyotyping to determine chromosomal sex, which can help identify conditions such as 46,XY DSD, 46,XX DSD, ovotesticular DSD, and sex chromosome DSD 1.
- Further evaluation may involve pelvic ultrasound, gonadal biopsy, and molecular genetic testing to identify primary genetic defects, if known, allowing for more specific diagnosis and limited use of general terms 1.
- Genetic testing is crucial in diagnosing DSD, as it can help identify specific genetic mutations associated with these conditions, guiding diagnosis and treatment.
- In some cases, a trial of hormonal therapy may be used to assess responsiveness and guide diagnosis, although this is not a primary diagnostic step.
Importance of Accurate Diagnosis
Accurate diagnosis of DSD conditions is essential for providing appropriate medical care and support, as well as addressing the psychological and social aspects of these conditions. By following a comprehensive diagnostic approach, healthcare providers can ensure that individuals with DSD receive the care they need to thrive.

Diagnosis Process for Intersex (Disorders of Sex Development, DSD) Conditions
The diagnosis process for intersex conditions, also known as Disorders of Sex Development (DSD), involves a comprehensive evaluation of the individual's physical characteristics, hormonal profile, genetic makeup, and internal genital organs. The following steps are typically involved in the diagnosis process:
- Physical examination to assess the external genitalia and other physical characteristics [(2,3,4,5,6)]
- Chromosomal evaluation, such as karyotyping, to determine the individual's sex chromosome constitution [(2,3,4,5,6)]
- Hormonal profile assessment, including measurements of testosterone, luteinizing hormone, and follicle-stimulating hormone [(2,5)]
- Pelvic ultrasound or other imaging studies to evaluate the internal genital organs [(2,4,5,6)]
- Gonadal biopsy or surgical exploration to confirm the presence of ovarian and testicular tissue [(2,3,4,5,6)]
- Consultation with a multidisciplinary team, including pediatric urology, endocrinology, genetics, psychology, and pathology, to determine the best course of treatment and management [(4,5)]
Key Considerations in Diagnosis
Some key considerations in the diagnosis of intersex conditions include:
- The presence of ambiguous genitalia or other physical characteristics that do not fit typical male or female patterns [(2,3,4,5,6)]
- A family history of intersex conditions or other disorders of sex development 3
- The individual's sex chromosome constitution, including the presence of mosaicism or chimerism [(3,6)]
- The presence of internal genital organs, such as a uterus or testes, and their location and development [(2,3,4,5,6)]
Importance of Early Diagnosis and Treatment
Early diagnosis and treatment of intersex conditions are crucial to ensure the best possible outcomes for individuals with these conditions. Delayed diagnosis and treatment can lead to complications, such as hematospermia 2, and can also impact the individual's quality of life and psychological well-being 4. A multidisciplinary approach to diagnosis and treatment, involving consultation with specialists from various fields, is essential to provide comprehensive care and support for individuals with intersex conditions [(4,5)].
