Abstract:

Orgasm and ejaculation are two separate physiological processes that are sometimes difficult to distinguish. Orgasm is an intense transient peak sensation of intense pleasure creating an altered state of consciousness associated with reported physical changes. Antegrade ejaculation is a complex physiological process that is composed of two phases (emission and expulsion), and is influenced by intricate neurological and hormonal pathways. Despite the many published research projects dealing with the physiology of orgasm and ejaculation, much about this topic is still unknown. Ejaculatory dysfunction is a common disorder, and currently has no definitive cure. Understanding the complex physiology of orgasm and ejaculation allows the development of therapeutic targets for ejaculatory dysfunction. In this article, we summarize the current literature on the physiology of orgasm and ejaculation, starting with a brief description of the anatomy of sex organs and the physiology of erection. Then, we describe the physiology of orgasm and ejaculation detailing the neuronal, neurochemical, and hormonal control of the ejaculation process.

    Alwaal et al. stated: “Ejaculatory dysfunction is a common disorder, and currently has no definitive cure”.
    The duration of penile-vaginal intercourse is not important for a woman’s
    orgasm. PE is not a disease and must not be classified as a male sexual
    dysfunction. Teens and men by masturbation can understand their sexual response and learn ejaculatory control with the stop-start method and the squeeze technique, without a drug therapy. Male ejaculation does not automatically mean the end of sex for most women. Touching and kissing can be continued almost indefinitely; non-coital sexual acts after male ejaculation can be used to produce orgasm in women.
