Precocious puberty following severe head trauma.

P W Shaul, R B Towbin, S D Chernausek

    American Journal of Diseases of Children (1960)
    |May 1, 1985

    Summary

    Severe head trauma can trigger true precocious puberty in children by activating the hypothalamic-pituitary axis. This rare condition suggests damage to brain areas that normally inhibit puberty onset.

    Area of Science:

    • Pediatric Endocrinology
    • Neuroendocrinology
    • Trauma Research

    Background:

    • True precocious puberty is typically caused by central nervous system (CNS) issues.
    • Sexual precocity following head trauma is considered rare.

    Observation:

    • Two children developed precocious puberty within three months of severe head trauma.
    • Luteinizing hormone-releasing factor infusion confirmed premature activation of the hypothalamic-pituitary axis.

    Findings:

    • Exogenous head trauma can lead to precocious puberty.
    • The precise mechanism is unknown, but likely involves damage to extra-hypothalamic areas that restrain gonadotropin secretion.

    Implications:

    • Head trauma may disrupt neuroendocrine control of puberty.
    • This finding expands the known causes of precocious puberty.
    • Further research is needed to understand the exact mechanism linking head trauma to precocious puberty.
