Structure and Function
- The male accessory glands are a group of organs that produce and secrete fluids that make up semen, which nourish and transport sperm during ejaculation.
- The main male accessory glands are:
- Seminal vesicles: produce 60% of semen, including fructose, which provides energy for sperm.
- Prostate gland: produces 30% of semen, including enzymes that help break down sperm membranes.
- Urethral glands (also known as Cowper's glands): produce mucus that helps lubricate the urethra.
- Bulbourethral glands (also known as Cowper's glands): produce mucus that helps lubricate the urethra.
Functions of Semen
- Provides a medium for sperm to swim in
- Nourishes sperm with nutrients and energy
- Helps to buffer the acidity of the vagina
- Lubricates the urethra during ejaculation
Clinical Significance
- Infections or inflammation of the male accessory glands can lead to conditions such as prostatitis, epididymitis, or seminal vesiculitis.
- Benign prostatic hyperplasia (BPH) is a common condition in older men that can lead to urinary symptoms.
- Cancer can occur in the prostate gland, seminal vesicles, or other male accessory glands.
