Leydig cell hypofunction resulting in male pseudohermaphroditism
Fertility and Sterility
|May 1, 1982
Summary
This study investigates male pseudohermaphroditism in an 11-year-old patient. Inadequate Leydig cell function, unrelated to LH receptors, was identified as the cause.
Area of Science:
- Endocrinology
- Genetics
- Pediatrics
Background:
- Male pseudohermaphroditism is a disorder of sex development characterized by male chromosomal sex and ambiguous or feminized external genitalia.
- Understanding the underlying causes is crucial for diagnosis and management.
Observation:
- An 11-year-old patient presented with female-appearing external genitalia, inguinal gonads, and posterior labial fusion.
- Basal testosterone levels were low, with elevated luteinizing hormone (LH) and follicle-stimulating hormone (FSH).
Findings:
- Human chorionic gonadotropin (hCG) stimulation did not increase testosterone or its precursors.
- Normal responses to adrenocorticotropic hormone (ACTH) and normal 5 alpha-reductase activity were observed.
- Microscopic examination revealed a reduced number of Leydig cells, suggesting impaired Leydig cell function.
Implications:
- The findings suggest male pseudohermaphroditism due to inadequate Leydig cell function, independent of LH receptor issues.
- This case highlights the importance of Leydig cell assessment in diagnosing disorders of sex development.
- Further research into Leydig cell dysfunction is warranted.
