    Area of Science:

    • Reproductive Endocrinology
    • Hormone Biology
    • Biochemistry

    Background:

    • Relaxin is a polypeptide hormone structurally related to insulin, found across species.
    • Its primary sources include the corpus luteum and decidua during pregnancy.
    • Historically, its role in humans was uncertain due to impure preparations.

    Purpose of the Study:

    • To review the known roles and structure of relaxin.
    • To highlight advancements in relaxin purification and assay development.
    • To establish the significance of relaxin in human reproduction.

    Main Methods:

    • Review of existing literature on relaxin.
    • Analysis of structural data for purified porcine and rat relaxins.
    • Discussion of radioimmunoassays and receptor site identification.
