Penile agenesis: a report of six cases
Insights
Penile agenesis is a rare birth defect occurring in 1 in 30 million births. Early medical and psychological interventions are crucial for affected infants.
Area of Science:
- Medical Genetics
- Pediatric Surgery
- Endocrinology
Background:
- Agenesis of the penis is an exceptionally rare congenital anomaly with an incidence of 1 in 30 million births.
- Limited published case reports (approximately 70) highlight the scarcity of clinical experience with this condition.
Observation:
- This complex malformation necessitates immediate neonatal assessment.
- Early female sex assignment is critical.
- Gonadectomy within the first few days of life is recommended to mitigate the effects of the neonatal testosterone surge.
Findings:
- The testosterone surge between days 10 and 60 of life can induce male gender sex characteristics.
- Timely gonadectomy prevents virilization and facilitates gender identity development.
Implications:
- Prompt medical and surgical management aids families in accepting the child's assigned gender.
- Early intervention can significantly reduce psychological distress for the child and family.
- Establishing clear guidelines for managing penile agenesis is essential for improving patient outcomes.
Abstract:
Agenesis of the penis is an extremely rare anomaly, occurring only once in 30 million births. This low incidence is responsible for the limited experience with this anomaly. There are only about 70 published cases, most reports being of one or two patients. This complex malformation requires urgent assessment at birth for several reasons: Female sex assignment is required early. Gonadectomy should be performed in the first few days of life to prevent male gender sex marking from the testosterone surge occurring between the tenth and the 60th day of life. Early gonadectomy and genital reconstruction helps the family to accept the child's altered gender and to reduce psychological problems.
