  1. Reproductive System Explain the structure of the male reproductive system Analyze the function of the male reproductive system Explain the structure of the female reproductive system Analyze the function of the female reproductive system Discuss characteristics and treatment of common reproductive disorders

  2. Male Reproductive System Testis and Epididymis • Testes produce male gametes (spermatozoa) and male sex hormone- testosterone • Found in pouch of skin called a scrotum • Size of small egg • Made up of 250 lobules, each with coiled seminiferous tubules-where sperm develop • They join to form the epididymis where sperm are stored they join at the vas deferns

  3. Descent of the testes In embryo, testes formed in the abdomen During last 3 months, migrate into scrotum Cryptorchidism- when testes don’t descend Rx-surgical procedure before puberty Penis Contains erectile tissue End of penis covered by loose fitting skin –foreskin Foreskin removed during circumcision Vas Deferens Runs from epididymis to ejaculatory duct Seminal vesicles connect to vas deferens secretion nourish sperm Ejaculatory duct- connect vas deferens with urethra Scrotum Sac of skin that contains testes

  4. Prostate gland • Surrounds beginning of urethra • Size and shape of a chestnut • Secretes a fluid that enhances sperm motility Bulbourethral glands • Located on either side of prostate below prostate • Add alkaline secretion to semen that helps sperm live longer

  5. Erection and Ejaculation Urethra has a dual role-excretion of urine and to expel semen Erection caused when erectile tissue fills with blood Ejaculation expels semen Impotence unable to copulate (hold an erection) Infertility When conception does not occur- caused by damage to fallopian tubes, low sperm count, hormone imbalance, other disorders

  6. Male Reproductive Disorders Vasectomy male sterilization, removal of part of the vas deferens

  7. BPH (BENIGN PROSTATIC HYPERTROPHY) ·Enlarged prostate ·More than half of men in their sixties and 90% of men in their seventies have some symptoms ·Prostate enlarges but capsule does not, causing prostate to clamp down on urethra. This causes the bladder to become irritable, causing urinary frequency ·Diagnosis by rectal exam, ultrasound, and cystoscopy Rx – usually prostatectomy – laser surgery, sometimes no Rx

  8. The scrotum contains the: Each lobe of the testis contains one to four highly twisted: The foreskin of the penis is also known as the: What are the male gametes? What ducts connect the vas deferens with the urethra? What structure connects the testes with the ductus deferens? What male reproductive gland surrounds the opening of the bladder leading into the urethra? Test your Gray Matter testes Ejaculatory duct Seminiferous tubules epididymis prepuce prostate spermatozoa

  9. The prostate gland is the size and shape of a: The external organs of the male reproductive system are the: The vas deferens begins in the: Sperm are produced in the: The male hormone produced by the testes is: Sperm are stored in the: Which of the following glands does not produce a secretion to transport sperm? Bartholin’s gland, Cowpers gland, Prostate gland, or Seminal vesicles What structure serves as a storage site for sperm and as the excretory duct of the testis? chestnut testes testosterone Scrotum + penis epididymis scrotum Vas deferens
