- - - - small sores or cluster of blisters on penis
    - - blisters in or around thev agina
      - fever and headaches
- - - - epididymis
      - ductus defernes
      - urethra
    - - seminal vesicle
      - prostate gland
      - bulbourethral gland
    - - tunica albuginea
        
        capsule surrounding the testes
      - septa
        
        extension of the capsule that extend into the testes and divide it into9 tubules
  - - - triggered by low levels of testosterone
      - controlled by negative feedback
    - - causes secondary sex characteristics
        
        deepening of voice
        
        increased hair growth
        
        enlargement of skeletal muscles
        
        thickening of bones
- - - - fibrous capsule called tunica albuginea
      - outer cortex houses developing female gamete, th eoocyte , within follicles
      - inner medulla contains loose connective tissue w large blood vessels and nerves
    - - uterine ( fallopian) tube
      - uterus
      - vagina
  - - - low levels causes release of FSH
      - high levels causes release of LH and GnRH
      - thickening of uterine wall
      - causes secondary sex characteristics
        
        breast development
        
        skelatal muscle growth and bone thickning
        
        widening of hips
        
        appearance of bodily hair
        
        increase in fat beneath the skin
        
        onset on menses
- - - - day 1-14
      - extends from the beginning of menstruation until ovulation
      - FSH causes follicular cells develop into primary follicle
      - follicular cells secrete estrogen to become secondary follicle
      - only one follicle become graafian follicle
    - - day 14
      - triggered by sudden spike increase in LH caused by steady increase in estrogen stimulating the pituitary gland
      - graafian follicle releases the oocyte
      - slight rise in progesterone just before ovulation cause basal body temp to rise about 04-0.6 F
    - - day 15-28
      - when follicle expels the oocyte, the empty shell becomes corpus luteum
      - corpus luteum secretes progesterone some estrogen, and inhibin which suppresses FSH
      - in the absence of pregnancy, corpus luteum becomes corpus albicans causing the decrease in progesterone and estrogen
      - if pregnancy occurs, the corpus luteum continues to secrete progesterone and estrogen
  - - - day 1-5
      - decline of estrogen and progesterone cause the spiral arteries to contract, cells become ischemic and die, and are sloughed off or shed
      - bleeding lasts 3-5 days
    - - day 6-14
      - estrogen stimulates growth of blood vessels of the endometrium, causing it to double in thickness
      - thickening of endometrium allows ovulated egg to be caught to cause implantation
    - - day 15-28
      - in response to rising levels of progesterone by the corpus luteum, the uterus becomes ready for pregnancy
      - uterine glands enlarge and secrete nutrients to sustain the embryo until implantation occurs
