Intersex: four cases in one family

Area of Science:

• Medicine
• Genetics
• Endocrinology

Background:

• Intersex conditions, particularly ambiguous genitalia, pose diagnostic and management challenges in medicine.
• While many cases present neonatally, some individuals are diagnosed later in life due to functional issues or delayed development.
• Familial occurrence and parental consanguinity suggest a potential genetic component in certain intersex variations.

Purpose of the Study:

• To describe a rare familial cluster of ambiguous genitalia.
• To investigate the underlying cause and classification of these intersex cases.
• To emphasize the importance of patient and parental involvement in gender assignment decisions.

Main Methods:

• Clinical examination of four related patients with ambiguous genitalia.
• Family history including consanguinity and previous cases of genital ambiguity.
• Hormonal and genetic assessments: buccal smear, karyotyping (46XY), and gonadal biopsies.
• Imaging studies: abdominal ultrasound to identify Müllerian structures.

Main Results:

• Four related patients (ages 4, 13, 15, 23) presented with ambiguous genitalia, penoscrotal hypospadias, and bifid scrotum.
• Two elder patients developed gynecomastia; Müllerian structures were identified in them via ultrasound.
• Karyotype was 46XY in all, with immature testicular tissue and azoospermia on biopsy, consistent with dysgenetic male pseudohermaphroditism.

Conclusions:

• The presented cases represent a rare form of ambiguous genitalia, classified as dysgenetic male pseudohermaphrodites.
• Genetic factors, possibly linked to consanguinity, may play a role in this familial intersex condition.
• Collaborative decision-making with patients and parents is essential for appropriate gender assignment and management.
