Presentation transcript:

Male Reproduction Testosterone: Male sex hormone   ~Testosterone causes the production of sperm. Sperm: Male reproduction cell ~Two biological functions of the male reproduction system: 1.Production of sperm 2. Transfer of sperm to the female body during intercourse

Ejaculation: Fluid from prostate, fluid from seminal vesicles and 300-400 million sperm all combine to make semen.   ~During ejaculation, semen is propelled from penis. Semen: a thick fluid containing sperm and other secretions from male reproduction organs. Fertilization: Is the union of a reproduction cell from a male and one from a female. Circumcision: Surgical removal of the foreskin of the penis. Foreskin-penis is covered w/ a fold of skin at birth.

External Organs  Penis: Tube-like organ attached to the trunk of the body just above testes. ~Functions: Sexual reproduction, sexual pleasure and elimination of waste.   Scrotum: Protects sperm by keeping the testes 3-4 degrees below normal body temperature. ~If the temp. rises, the muscles of the scrotum relax, lowering the testes. ~If the temp. drops, muscles contract, pulling testes closer to the body.

~ Thick muscle walls of the Vas Deferens propel the sperm forward. Internal Organs   Testes- Produce Sperm Epididymis: Stores newly produced sperm for about 64 days until fully matured. Vas Deferens :A pair of connecting tubes, each 18 inches long that lead up into the males’ body toward other internal organs. ~ Thick muscle walls of the Vas Deferens propel the sperm forward. Seminal Vesicles: Attached near the base of the bladder to the Vas Deferens. ~The fluid contains nutrients and mixes w/ sperm.

Prostate Gland: Small gland that surrounds Urethra. Add fluid to sperm   Cowpers Gland: Two pea –sized glands that open into Urethra, secrete a clear sticky fluid to cleanse the urethra of urine and left over sperm. Add fluid to sperm. Urethra: Tube-like organ that travels through the penis, carries sperm and urine. ~Semen and urine do not pass through the body at same time. ~A muscle near the bladder contracts, preventing urine from entering urethra.

Bladder Urethra Cowpers Gland Penis Seminal Vesicle Epididymis Vas Deferens Testicle

Prostate Cancer: Uncontrolled growth of cells. Male Concerns  Hernia: Part of the body pushes through the muscle wall normally keeping it in. (Example: Inguinal Hernia- part of the intestine pushes through into scrotum. *Surgery is need to correct.)   Sterility: Sperm is weak, malformed, sparse or nonexistent. Fertilization does not occur. Inability to conceive a child ~Causes- Exposure to chemicals, smoking, STD’s, malfunction of one of the internal organs, hormone imbalances, varicose vein in scrotum Infertility: Inability to conceive a child on your own. Causes: Blockage, low sperm count, Varicose vein problem. Procedures can be done to help make a child. Prostate Cancer: Uncontrolled growth of cells. ~Treatments- Removal of prostate or radiation therapy and hormonal therapy. Testicular Cancer: Signs- Enlargement of testicles, lump or fluid collection, dull ache in the lower abdominal or groin area. ~Frequently males 15-35.
