System
The Male Reproductive System
• The functions of the male reproductive system are to produce sex hormones, produce and store sperm, and deliver sperm to the female reproductive system
External Organs
• Penis – The male sex organ for reproduction and
delivery of urination and sperm
• Scrotum– a sac that holds the testes– Protects sperm by Keeping testes at a
temp slightly below normal body temp (normal=98.6)
Internal Organs• Testicles– Also known as testes
– Two glands that produce sperm (reproduce cells) and testosterone (sex hormone that affects the production of sperm and signals physical changes at puberty, such as growth of facial hair)
– located in the scrotum
Sperm
• Tadpole like with a nucleus and a tail– 2-6 weeks to mature in the epididymis
– Combines with fluid from other organs to produce semen/seminal fluid
– 100 million are produced a day
• Epididymis – A coiled tube, located at the outer surface of
the of testes. Stores sperm temporarily– Sperm matures here
• Vas Deferens– Tube connecting the epididymis to the
urethra. Sperm travels through the Vas Deferens to the seminal vesicles
– Semen is produced in the seminal vesicles
• Urethra – a tube that extends from the bladder
through the penis to the outside of the body. It carries urine and sperm, but not at the same time
The Journey of Sperm
1. The testes are where sperm are manufactured
2. Epididymis receives immature sperm from the testes and stores it several days
3. Sperm then travels through the Vas Deferens to the seminal vesicles where semen is produced
The Journey of Sperm
4. The Prostate gland adds fluids that protects sperm. Sperm passes through the prostate gland and empties into the urethra
5. Sperm is released through Ejaculation. This occurs when the penis is in an erect state
Care for the Male Reproductive System
• Involves proper hygiene, protection, and self-examination
– Shower daily by completely cleaning the penis– Protection from Trauma
• Wear a “cup” during athletic activities
– Performing testicular self-examinations• Check for lumps or tenderness• Testicular cancer is one of the most common type of
cancer in males between the ages of 15 and 34
Care for the Male Reproductive System– Seek medical attention when you show signs of an
infection– Practice safe sex
