Human Male Genital Organs

Quick Answer: The human male genital organs model is an anatomical teaching model of the male reproductive system, showing the testes, epididymis, vas deferens, accessory glands and penis, often partly in section. It is used in secondary biology, nursing and health education to teach reproductive structure and function.

Structures of the Male Reproductive System

A male genital organs model concentrates on the reproductive organs rather than the whole pelvis. The testes sit in the scrotum outside the body cavity, where the temperature is a little lower than core body temperature, as sperm production requires. Inside each testis, coiled seminiferous tubules produce sperm, while the interstitial, or Leydig, cells between the tubules produce testosterone.

Sperm move from the testis into the epididymis, a tightly coiled duct on its back surface where they mature and are stored, then into the vas deferens, which runs up in the spermatic cord with blood vessels and nerves. Near the bladder, the vas deferens joins the duct of the seminal vesicle to form the ejaculatory duct, which passes through the prostate gland and opens into the urethra. The seminal vesicles, prostate and small bulbourethral glands add the fluids that make up most of the semen.

The penis contains three columns of erectile tissue: two corpora cavernosa along the upper side and the corpus spongiosum below, which surrounds the urethra and expands at the tip as the glans. Many models show some of these structures in section, and exactly which organs are sectioned or removable differs between versions; the male urogenital model adds the urinary organs for teaching the two systems together.

Care & Handling

• Keep the male genital organs model in a closed box or cupboard between lessons, both to protect it and so it is used in a planned teaching context.
• Wipe with a soft, lightly damp cloth; avoid scrubbing painted sectional surfaces.
• Check that any removable sections are returned after each class.

Specifications

Applications

• Teaching the pathway of sperm from the testis to the urethra
• Explaining the roles of the accessory glands in producing semen
• Lessons on hormones, including where testosterone is made
• Health education topics such as testicular self-examination and the location of the prostate

Frequently Asked Questions

Why are the testes outside the body cavity?

Sperm production needs a temperature slightly below core body temperature. The scrotum keeps the testes cooler and can draw them closer to the body in the cold.

What is the epididymis?

It is a long, tightly coiled duct lying along the back of each testis. Sperm pass into it from the testis, mature there and are stored until they move on into the vas deferens.

Which glands produce seminal fluid?

The seminal vesicles, the prostate gland and the bulbourethral glands. Their secretions nourish the sperm and make up most of the volume of semen.

Where is testosterone produced?

Mainly in the interstitial, or Leydig, cells that lie between the seminiferous tubules of the testis. Testosterone drives the development of male characteristics and supports sperm production.

What is the spermatic cord?

It is a bundle running from the abdomen to each testis, containing the vas deferens, the testicular artery and veins, nerves and lymph vessels, wrapped in layers of connective tissue and muscle.

Is this model appropriate for school use?

Yes, when used within the reproductive biology or health education curriculum. It presents anatomy factually, and teachers usually introduce it alongside diagrams and a female model for balanced lessons.
