couple concerned about long term impacts of birth control pills on body,…

- - - - root
        
        attaches penis to base of abdomen
      - shaft
        
        3 chambers internally of sponge-like tissue
      - glans
        
        naturally covered in foreskin
  - - - protects testicles
        
        climate controlled, may contract and relax
        
        holding testicles closer or farther from body's warmth
  - - - brings sperm to maturity
        
        carries and stores sperm
  - - - housed in testes
        
        make testosterone and sperm
        
        seminiferous tubules in tested make the sperm
  - - - contracts to force mature sperm through tube
        
        takes to urethra for ejaculation
  - - - empty from vas deferens into urethra
  - - - release clear, lubricating fluid to help urethra and neutralize any acidity
- - - - support oocyte
        
        Primordial Follicle first
        
        forms into primary follicle, secretes estrogen,
        
        which matures to secondary follicle
        
        which forms large vesicular follicle
        
        which also contains secondary oocyte

- - - - few into secondary follicles
        
        then usually one into vesicular follicle
  - - - 20 primordial follicles mature
        
        stimulated by leutinizing hormone and follicular-stimulating hormone
        
        a few become secondary follicles
        
        then usually one into vesicular follicle
        
        primary oocyte in follicle forms two cells
        
        through meiosis I
        
        1 more item...
    - - secondary oocyte released from follicle
        
        induced from LH secretion increase
        
        Antrum swells
        
        until ovarian surface thins
        
        ruptures eventually, causing the release of the secondary oocyte
    - - follicle cells remaining become corpus luteum
- - - - the functional endometrial layer sloughed off
        
        during the "bleeding days"
    - - new endometrium functional layer developed
    - - progesterone secretion increase from corpus luteum
        
        vascularization increase and uterine gland development
      - if fertilization doesn't happen
        
        corpus luteum degrades
        
        progesterone levels drop
        
        functional layer sloughed off
- - - - goal is to prevents main ejaculation fluid from entering vagina
  - - - sperm unable to leave testes
