    Summary

    Biochemical factors, including hormones and pheromones, influence sexual behavior and attraction. This study details the complex hormonal and neural pathways, including endorphins and enzymes, involved in sexual response and orgasm.

    Area of Science:

    • Biochemistry
    • Neuroendocrinology
    • Behavioral Science

    Context:

    • Pareunia, or sexual intercourse, involves complex biochemical processes.
    • Hormonal factors from embryonic genital crests influence both genital and neural sexualization.
    • Exoactones, or pheromones, play a significant role in inter-individual attraction.

    Purpose:

    • To analyze the biochemical factors governing the process of pareunia.
    • To elucidate the roles of hormones, pheromones, and neural pathways in sexual behavior.
    • To investigate the enzymatic phenomena associated with orgasm.

    Summary:

    • The study examines the hormonal basis of sexualization, including the influence of embryonic genital crests on behavior.
    • It details the involvement of the hypothalamo-adeno-hypophyso-(cortico)-gonadal axis, sexosteroids, prolactin, vasopressin, oxytocin, and melatonin.
    • Neuromodulation via catecholaminergic, cholinergic, and indolaminergic systems, along with endorphin release during orgasm, is discussed.
    • Enzymatic activity, specifically depolymerases in vaginal content during orgasm, is highlighted as a crucial, often overlooked, factor.

    Impact:

    • Provides a comprehensive biochemical overview of sexual function and response.
    • Highlights the intricate interplay between hormonal, neural, and enzymatic systems in mediating sexual behavior.
    • Underscores the significance of previously underappreciated enzymatic phenomena in sexual physiology.
