Prostate Gland Anatomy

The prostate gland plays an important role in the male reproductive system, responsible for releasing semen alongside fluid from other glands and the testicles. The fluid produced by the prostate gland ensures that sperm cells are transported safely for fertilisation.

To support your studies, our detailed prostate anatomy posters and charts provide a visual breakdown of the prostate gland’s zones, blood supply, and function. These resources are ideal for students, tutors, and healthcare professionals who want to consolidate their understanding of male reproductive anatomy.

With clearly labelled anatomical features, our charts are well-suited for classrooms, clinics, and personal revision spaces.

The prostate gland is about the size of a walnut. It is located below the bladder and in front of the rectum. It is surrounded by a fibrous capsule with nerves and vasculature, which is covered by a layer of fascia. The urethra passes through the centre of the prostate, allowing urine and semen to flow out of the body. The gland is composed of both glandular and muscular tissue, which helps secrete and propel seminal fluid during ejaculation.

Our realistic anatomical models give a tactile, three-dimensional view of this essential male reproductive organ. They accurately depict the gland’s internal zones, its relationship to surrounding organs, and the course of the urethra through the gland.

Perfect for educational demonstrations, student learning, or patient education, these models are a valuable tool for anyone seeking a deeper grasp of prostate anatomy and function.

The prostate gland is divided into three zones: the peripheral zone, the central zone, and the transition zone.

• The peripheral zone is the outer region and occupies the back surface of the gland. This is the area where doctors will examine when they check for prostate cancer.
• The central zone is the surface that contains the ejaculatory ducts.
• The transition zone is the innermost zone and surrounds the area where the urethra enters the gland.

The blood supply of the prostate gland comes from the internal pudendal artery, which also supplies other structures of reproduction. The inferior vesical artery and the middle rectal arteries also provide blood to the prostate gland. These two arteries are branches of the internal iliac artery. Venous drainage flows from the prostatic plexus into the internal iliac veins.

Semen is made from various fluids to which the prostate gland contributes. The fluid produced is important for the proper function of sperm cells from the testicles.

Enzymes - proteins that speed up chemical reactions - are present in this fluid and help nourish the sperm cells. Some enzymes make the semen thinner, allowing for better propulsion during ejaculation and improving the chances of fertilisation.

The fluid itself is alkaline, offering protection to sperm cells once they enter the acidic environment of the vagina. This increases the lifespan of the sperm cells and boosts the likelihood of successful fertilisation.

Understanding anatomy can be far more effective with high quality visual tools. Our range of anatomical models, posters and revision guides guides allow students and professionals to deepen their understanding through visual and tactile learning. Whether you're preparing for an exam, teaching a class, or working in a clinical setting, our resources provide a practical and engaging way to study human anatomy.
