Menstrual cycle

• 1.Pituary glands release first which causes eggs to mature in ovary
• 2.Ovaries produce oestrogen which repaires lining of uterus and thickens it
• 3)LH is released by pituary glands and causes ovary to release eggs into oviduct(ovulation)
• 4)afterwards progesterone is produced by ovaries(maintains lining of uterus keeps it intact)
• 5)causes uterus to shed lining(period) and repeats every 28 days
• The reproductive hormones interact with each other during menstrual cycle
• Progesterone helps prepare body for pregnancy by:

  • Maintaining lining of uterus
  • Helps oestrogen stop production of LH
• Oestrogen

  • Eggs don't mature because pituary glands don't release FSH
  • evaluation caused because LH released instead
  • Cause ovaries to release more progesterone
