    Area of Science:

    • Sports Medicine
    • Endocrinology
    • Reproductive Health

    Background:

    • Secondary amenorrhea in athletes is a complex condition often classified under chronic anovulation syndrome.
    • The exact mechanisms underlying athletic amenorrhea remain unclear, despite various proposed contributing factors.

    Purpose of the Study:

    • To review the incidence, treatment, associated characteristics, proposed mechanisms, and endocrine profiles of secondary amenorrhea in athletes.
    • To evaluate proposed mechanisms by analyzing basal hormone concentrations and exercise-induced endocrine responses.

    Main Methods:

    • Literature review of studies on secondary amenorrhea in athletes.
    • Analysis of basal and exercise-induced endocrine profiles in athletes.
    • Identification and evaluation of methodological errors in existing research.

    Main Results:

    • Incidence rates for athletic amenorrhea vary widely (1-44%) due to undefined diagnostic criteria and population differences.
    • Proposed mechanisms involve body composition, training, maturity, sport type, diet, and psychological stress.
    • Conflicting results in studies are often attributed to methodological errors.

    Conclusions:

    • Further research is needed to elucidate the precise mechanisms of secondary amenorrhea in athletes.
    • Standardized definitions and rigorous methodologies are crucial for accurate research findings.
    • Understanding the endocrine profile is key to evaluating proposed causative factors.
