Study Notes
The Male Reproductive System
- The male reproductive system consists of organs that produce and release sperm, including the testes, epididymis, seminal vesicles, prostate, and vas deferens.
- The testes produce sperm and the hormone testosterone, and are housed in the scrotum.
- The epididymis is a coiled tube that stores sperm, and leads into the vas deferens, which carries sperm to the penis.
Sexual Reproduction
- Sexual reproduction is the process by which two individuals combine their genetic material to create a new individual.
- In humans, sexual reproduction involves the combination of sperm and egg cells.
- The male reproductive system plays a crucial role in sexual reproduction by producing and delivering sperm.
Testes and Vas Deferens
- The testes are the organs that produce sperm and testosterone.
- The vas deferens is a tube that carries sperm from the epididymis to the penis.
Seminal Vesicles and Prostate
- The seminal vesicles produce fluids that mix with sperm to form semen.
- The prostate gland produces fluids that make up semen and helps to nourish sperm.
- The urethra is the tube that carries urine and semen out of the body.
Penis
- The penis is the male organ used for sexual intercourse and urination.
- The penis contains erectile tissue that fills with blood during sexual excitement, causing an erection.
- The glans penis is the sensitive tip of the penis, and is covered by a flap of skin called the foreskin.
Diseases and Disorders of the Male Reproductive System
- Prostatitis is inflammation or infection of the prostate, and can cause symptoms such as lower back or groin pain, difficulty urinating, and blood in the urine.
- Epididymitis is inflammation of the epididymis, and can cause symptoms such as testicular swelling, tenderness, and pain, as well as fever and discharge from the penis.
- Orchitis is inflammation of the testes, and can cause symptoms such as pain, swelling, and tenderness.
- Testicular cancer is cancer of the testes, and can cause symptoms such as a painless lump on the testicle, swelling in the scrotum, and an achy feeling in the lower abdomen.
- Prostate cancer is cancer of the prostate gland.
Caring for the Male Reproductive System
- To maintain the health of the reproductive system, males can take steps such as practicing good hygiene, wearing a protective cup during contact sports, and performing regular testicular self-examinations.
- Testicular self-examinations can help detect signs of testicular cancer and hernia.
Testicular Self-Examination
- To perform a testicular self-examination, males should:
- Hold the top of the scrotum with one hand and gently pinch to keep one testis in place.
- Use the other hand to guide fingers and thumb along both sides of one testis, feeling for any lumps or bumps.
- Repeat the process for the other testis.
Visiting the Doctor
- Males should visit the doctor regularly to ensure the health of the reproductive system.
- If symptoms such as burning or pain during urination, blood or pus at the opening of the urethra, pain or burning in the lower abdomen, or rashes or sores on the penis occur, males should see a doctor right away.
