    Post-ejaculation seminal vesiculography reveals seminal tract dysfunction in infertile men. Abnormal seminal vesicle contraction indicates dysfunction, impacting fertility and contrast excretion.

    Area of Science:

    • Reproductive Medicine
    • Urology
    • Radiology

    Background:

    • Male infertility affects a significant portion of couples seeking reproductive assistance.
    • Assessing the function of the seminal vesicles and tracts is crucial for diagnosing male factor infertility.
    • Traditional vasoseminal vesiculography provides anatomical information but may not fully capture functional aspects related to ejaculation.

    Purpose of the Study:

    • To evaluate the utility of post-ejaculation vasoseminal vesiculography in assessing seminal tract function.
    • To correlate seminal vesicle contraction after ejaculation with male fertility status.
    • To determine if seminal tract dysfunction is a contributing factor in male sterility.

    Main Methods:

    • 16 cases of male sterility underwent vasoseminal vesiculography before and after ejaculation.

  • Contrast medium excretion into the ejaculate was assessed.
  • Seminal vesicle contraction post-ejaculation was evaluated radiographically.

    • Main Results:

    • In 12 cases, contrast medium was excreted, and seminal vesicles contracted post-ejaculation.
    • In 4 cases, minimal or no seminal vesicle contraction was observed after ejaculation.
    • Reduced seminal vesicle contraction correlated with abnormal seminal tracts and potential infertility factors.

    Conclusions:

    • Post-ejaculation seminal vesiculography is a valuable tool for assessing seminal tract function.
    • Lack of seminal vesicle contraction post-ejaculation suggests seminal tract abnormality and may be linked to male sterility.
    • Seminal tract function, as indicated by contraction and contrast excretion, is important for male fertility.
