geef de hormnale regleing

Folliculaire fase

  1. Hypothalamus maak hormoon GRF aan en geef aan hypofyse

  2. hyposfyse gaat lh en fsh afscheiden

    • fsh → folliekels rijpen waardoor oestrogeen geproduceerd worden → minder fsh en lh zodat niet teveel rijpen + verdikking baarmoederslijmvlies

    • veel oestrogeen → kritische drempel → meer GRF = ovulatie

lutale fase

  1. geel lichaampje maakt progesteron aan → ontwikkelen slijmkliertjs in baarmoederslijmvlies met rijk aan gycogeen

  2. oestrogeen en progesteron → negatieve terugkoppeling → grf word afgeremd → afbraak geel lichaampje BEHALVE BIJ BEVRUCHTING

menstruatie

= geen bevruchting

  • baarmoederslijmvlies wordt afgebrokkeld door bloedingen (duurt 5 dagen, 14 dagen na ovulatie)
