    Summary
    This summary is machine-generated.

    This study reviews pineal substances, including melatonin and polypeptides, for antigonadotropic activity. It investigates whether melatonin or arginine-vasotocin are the key pineal hormones responsible for observed effects.

    Area of Science:

    • Endocrinology
    • Neuroscience
    • Biochemistry

    Background:

    • The pineal gland produces substances with antigonadotropic activity.
    • Indole compounds and pineal polypeptides are key pineal substances studied.
    • Melatonin is the prototype of pineal-indole compounds.

    Purpose of the Study:

    • To present experimental data on pineal substances with antigonadotropic activity.
    • To discuss the roles of melatonin and arginine-vasotocin as potential pineal hormones.
    • To analyze the effects of melatonin and pineal extracts.

    Main Methods:

    • Literature review of experimental data.
    • Analysis of reported effects from specialty literature and authoress's studies.
    • Comparison of purified pineal extracts and melatonin administration.

    Main Results:

    • Observed effects after administration of melatonin and pineal extracts are presented.
    • Data from literature and authoress's studies are compiled.
    • The antigonadotropic activity of pineal substances is highlighted.

    Conclusions:

    • Melatonin and pineal polypeptides exhibit antigonadotropic properties.
    • The specific pineal hormones responsible for observed effects require further investigation.
    • Arginine-vasotocin is considered alongside melatonin as a potential key pineal hormone.
