Step 1
Day 1-5 lining of the uterus breaks down ( period )
Step 2
fsh produced - stimulates follicle to mature
Step 3
Oestrogen produced which builds up lining
Step 4
High levels of oestrogen cause lh to be released
Step 5
Mature egg is released ( ovulation)
Step 6
Progesterone released from corpus luteum to mantain lining
Step 7
If egg is not fertilised then progesterone and oestrogen levels drop
