  • Life Goes On
    • FSH (follicle stimulating hormone)-egg develops in the ovary
      • LH- (lutenising hormone)- controls ovulation
      • Released from the pituitary gland
        • LH- (lutenising hormone)- controls ovulation
    • Progesterone-maintains uterus wall
      • Oestrogen- repairs uterus wall
    • Negative feedback mechanisms
      • Triggered by hypothalamu-s
        • Menstrual cycle-levels of oestrogen and progesterone are low
    • Fertilisation does not occur- oestrogen and progesterone levels decrease
    • The pill- makes the body think it's pregnant, inhibits FSH release- eggs are not stimulated to develop
    • Fertility treatments- IVF, egg donation, artificial insemination
      • Moral and ethical dilemmas
    • Amniocentesi-s-extracting and testing amniotic fluid
      • Chromosomal analysis- blood test for genetic abnormalities
        • Carry risks of causing a miscarriage
