Signs and symptoms
Common signs and symptoms that may indicate this condition.
Warning signs - seek immediate care
Gonadal dysgenesis
Underdeveloped or streak gonads that fail to produce adequate hormones, often identified on imaging.
Requires immediate specialist evaluation; gonads may have malignant potential and require monitoring.
Hypertension
Elevated blood pressure that may be associated with certain genetic variants affecting steroid metabolism.
Seek immediate care for blood pressure readings above 180/120 or associated symptoms like headache or vision changes.
Primary amenorrhea
(reproductive)Complete absence of menstrual periods in a post-pubertal individual with 46-XY karyotype.
Frequency: 90-100% of patients
Primary infertility
(reproductive)Inability to conceive naturally due to gonadal dysgenesis or abnormal gonadal development.
Frequency: 95-100% of patients
Ambiguous genitalia
(reproductive)External genitalia with mixed male and female characteristics at birth, including partial fusion of labioscrotal folds or enlarged clitoris.
Frequency: 60-70% of patients
Absence of secondary sexual characteristics
(reproductive)Lack of breast development, pubic hair, and axillary hair progression during puberty.
Frequency: 70-80% of patients
Underdeveloped breasts
(reproductive)Failure of breast tissue to develop fully or at all due to inadequate estrogen production.
Frequency: 70-80% of patients
Short stature
(constitutional)Adult height below genetic potential due to absent pubertal growth spurt from sex hormone deficiency.
Frequency: 60-70% of patients
Absent uterus
(reproductive)Müllerian duct agenesis or underdevelopment resulting in absent or rudimentary uterine structure.
Frequency: 15-25% of patients
Diagnosis and tests
How this condition is diagnosed and what test results mean.
Initial screening tests
Standard diagnostic workup

Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Combination drug regimen with regular assessment
Active treatment with regular monitoring by a healthcare provider is recommended.
Gender assignment surgery
Surgical intervention for genital reconstruction based on assigned gender, typically performed after careful psychological evaluation and family counseling to determine the most appropriate course.
Hormone replacement therapy
Lifelong hormone supplementation appropriate to assigned gender, including estrogen or testosterone replacement to maintain secondary sexual characteristics and bone health.
Additional treatment options
Psychological counseling and support
Ongoing mental health support addressing gender identity concerns, adjustment issues, and family dynamics throughout development.
psychologicalRegular endocrine and genetic monitoring
Periodic evaluation of hormonal levels, growth patterns, and gonadal function to optimize treatment timing and outcomes.
monitoringGenetic counseling
Family education about the genetic basis of the condition, inheritance patterns, and implications for future family planning decisions.
