  • FSH from the pituitary stimulates an egg to mature (in a follicle) in an ovary.FSH also causes the ovary to release oestrogen, which limits the amount of FSH released and stimulates growth of the uterus lining.Peak of oestrogen causes LH to release from the pituitary.LH causes ovulation, an ovum is released into the fallopian tube. The remains of the follicle (corpus luteum) releases progesterone, maintains uterus lining and inhibits FSH production
  • If no fertilisation, corpus luteum breaks down and menstruation begins
  • If fertilisation occurs, corpus luteum continues to produce progesterone until placenta forms.
  • LH = Luteinizing Hormone
  • FSH = Follicle stimulating hormone
  • The uterus lining is lost during menstruation
  • Oestrogen stimulates the uterus lining to repair then continue to grow thicker and produce more blood vessels
  • Inhibition of FSH prevents follicles from maturing further
  • Progesterone maintains the thickness of the lining by inhibiting oestrogen production
  • Corpus luteum produces progesterone which stops ovulation occurring again
  • The corpus luteum = the remains of the follicle
  • The female reproductive system
  • FSH is produced in the pituitary gland
  • LH is also produced in the pituitary gland
  • Oestrogens are produced in the ovaries
  • Progesterone is produced in the ovaries
