    Study Notes

    Anatomy & Physiology of Male Reproductive System

    • Semen is produced from 4 glands: testes (5%), Cowper glands (5%), prostate gland (30%), and seminal vesicles (60%)
    • Semen has an alkaline pH of about 7.8 and contains fructose secreted from the seminal vesicles
    • Secretions of the seminal vesicle are drained by the ejaculatory duct
    • Denonvilliers’ fascia is located between the prostate gland and the anterior wall of the rectum
    • The prostate gland is supported by the obturator internus and levator ani muscles
    • The ejaculatory duct joins the urethra at the verumontanum, located at the center of the prostate
    • The central zone is located posterior to the periurethral region in the prostate
    • The fibromuscular zone is the most anterior zone in the prostate, while the peripheral zone is the most posterior
    • The prostate enlarges with aging, a process called benign hypertrophy
    • Prostatic specific antigen (PSA) is used for prostatic cancer screening, with a normal value below 4 ng/ml
    • Transrectal scanning provides better detail on the prostate and seminal vesicles, while transabdominal scanning is preferred for prostatic measurements
    • A normal prostate measures 3.8 cm length, 4 cm width, and 3 cm thickness (AP), while a normal seminal vesicle measures 5 cm in length and 1 cm in diameter
