Functions of the Male Reproductive System

The male reproductive system has several important functions necessary for sexual reproduction. These include:

1. Production of Sperm (Spermatogenesis)

• Occurs in the seminiferous tubules of the testes.

• Controlled by hormones such as FSH (Follicle Stimulating Hormone) and testosterone.

• Begins at puberty and continues throughout life.

2. Storage and Maturation of Sperm

• Sperm is stored and matures in the epididymis.

• Gains motility and the ability to fertilize an egg during this phase.

3. Transport of Sperm

• Through the vas deferens, sperm moves from the epididymis to the urethra.

• During ejaculation, sperm is mixed with seminal fluid to form semen.

4. Production of Seminal Fluid

• Seminal vesicles, prostate gland, and bulbourethral glands secrete fluids that:

  • Nourish the sperm (fructose from seminal vesicles).

  • Protect sperm from vaginal acidity.

  • Provide motility aid.

5. Ejaculation

• A reflex action under sympathetic nervous system control.

• Involves the release of semen through the urethra.

6. Hormone Production

• Testes produce testosterone, responsible for:

  • Development of male secondary sexual characteristics.

  • Regulation of libido.

  • Maintenance of spermatogenesis.
