Male Reproductive System
MALE REPRODUCTIVE SYSTEM
EXTERNAL ORGANS Scrotum Testes Penis Foreskin
Scrotum A sensitive muscular sac held outside the body The testicles are held inside the scrotum Regulates the temperature of the testicles and the sperm
TESTICLES 2 small glands that are located in the scrotum Responsible for sperm production and release of testosterone in the body Can be a site for testicular cancer in males (typically in young men)
PENIS MALE REPRODUCTIVE ORGAN USED FOR INTERCOURSE CONTAINS 3 CYLINDERS WHICH BECOME FILLED WITH BLOOD WHEN A MALE HAS AN ERECTION HAS THREE PARTS: FORESKIN- SKIN THAT COVERS THE HEAD OF THE PENIS- CAN BE REMOVED DURING A PROCEDURE CALLED A CIRCUMSCISION SHAFT – longer part of the organ Glans- The smooth sensitive top of the penis
INTERNAL ORGANS SEMINAL VESICLES VAS DEFERENS PROSTATE GLAND COWPERS GLAND EPIDIDYMIS URETHRA URINARY BLADDER
SEMINAL VESICLES SEMINAL FLUID ORIGINATES IN THE SEMINAL VESICLE PROVIDES SEMINAL FLUID, THAT MIXES WITH SPERM TO CREATE SEMEN THIS FLUID CAN ALSO SPREAD HIV
VAS DEFRENS Connects the epididymis to the urethra for ejaculation. The sperm travel through here to be released by the penis. This can be a site for male sterilization through a procedure called a vasectomy Can also be a site of infertility if bacteria causes scar tissue to develop and block the tube
PROSTATE GLAND GLAND THAT IS THE SIZE OF A WALNUT AND LOCATED BELOW THE BLADDER RELEASES A NOURSHING FLUID FOR THE SPERM DURING EJACULATION CAN BE A SITE FOR CANCER IN OLDER MALES
COWPERS GLAND TWO TINY GLANDS LOCATED BELOW THE PROSTATE GLAND RESPONSIBLE FOR NEUTRALIZING THE SPERM IN ORDER TO SURVIVE IN THE FEMALES REPRODUCTIVE SYSTEM FLUID CLEANS THE URETHRA PRIOR TO EJACULATION. THIS FLUID CAN CAUSE STD’S AND PREGNANCY
EPIDIDYMIS TIGHTLY COILED TUBE CONNECTING THE VAS DEFERENS TO THE TESTICLES THE MATURED SPERM ARE STORED HERE FOR UP TO 2 WEEKS IF THE MATURED SPERM ARE NOT EJCAULATED THEY ARE BROKEN DOWN BY THE BODY
URETHRA PASSAGE WAY FOR THE SEMEN AND URINE TO LEAVE THE BODY
URINARY BLADDER STORAGE OF URINE UNTIL EXCRETION
PATHWAY OF THE SPERM AT YOUR TABLES (GROUPS OF 3) COMPLETE THE BLANKS IN YOUR NOTE PACKET ABOUT THE PATH THE SPERM TAKES TO LEAVE THE BODY. YOU WILL HAVE 5 MINUTES TO COMPLETE THE TASK. BE SURE TO WRITE IN PENCIL IN CASE YOU NEED TO ERASE!
PATHWAY OF THE SPERM---- ANSWERS PRODUCED IN THE TESTICLES STORED IN THE EPIDIDYMIS RELEASED INTO THE VAS DEFERNS PASSES THROUGH THE SEMINAL VESICLES PASSES THE PROSTATE GLAND PASSES THE COWPER GLAND ENTERS THE URETHRA TRAVELS DOWN THE PENIS AND OUT OF THE BODY
SPERM CELL HEAD- CONTAINS 23 CHROMOSOMES; EITHER X OR Y FOR GENDER; MALES DETERMINE THE GENDER OF BABY ACROSOMAL SAC- ABOVE THE HEAD; CONTAINS DIGESTIVE ENZYMES THAT ALLOW THE SPERM TO PENETRATE THROUGH THE EGG CELL NECK- CONTAINS MITOCHONDRIA TAIL- SIDE TO SIDE MOVEMENT TO PROPEL THE SPERM THROUGH THE VAGINA TO THE UTERUS AND FALLOPIAN TUBE
CARE FOR THE MALE REPRODUCTIVE SYSTEM GET REGULAR CHECK-UPS BATHE REGULARLY WEAR PROTECTIVE EQUIPMENT PERFORM SELF-EXAMINATIONS REGULARY PRACTICE ABSTINENCE
COMMON REPRODUCTIVE PROBLEMS INGUINAL HERNIA SEPERATION OF TISSUE ALLOWS INTESTINES TO PUSH INTO THE ABDOMEN NEAR TOP OF THE SCROTUM A bulge in the area on either side of your pubic bone A burning, gurgling or aching sensation at the bulge Pain or discomfort in your groin, especially when bending over, coughing or lifting A heavy or dragging sensation in your groin Weakness or pressure in your groin May require surgery
STERILITY RESULTS FROM TOO FEW SPERM LESS THAN 20 MILLION PER MILLIMETER OF SEMINAL FLUID CAN RESULT FROM: EXPOSURE TO X-RAYS RADIATION TOXIC CHEMICALS LEAD ANABOLIC STEROIDS DRUGS HORMONAL IMBALANCE STD’S
SEXUALLY TRANSMITTED DISEASES CHLAMYDIA/GONORRHEA- BACTERIAL INFECTION THAT CAUSES BURNING WHEN URINATING SYPHILLIS- BACTERIAL INFECTION; INITAIALLY PAINLESS, THEN RED SORES APPEAR GENITAL HERPES- VIRAL INFECTION; INITIALLY BLISTER LIKE SORES IN THE GENITALS; CAUSES UNPREDICTABLE OUTBREAKS
PUBERTY AND REPRODUCTION DEFINITIONS CONCEPTION- WHEN THE SPERM AND THE EGG MEET. THE SPERM FERRTILIZES THE EGG ENDOCRINE SYSTEM- RESPONSIBLE FOR THE RELEASE OF HORMONES IN THE BODY PITUITARY GLAND- LOCATED IN THE BRAIN AND SIGNALS THE ONSET OF PUBERTY
