Sexual Reproduction in Humans

My dear Secondary 4s,


I found a link here (Endocrinology of the Menstrual Cycle), that shows the changes in hormonal levels illustrated clearly in a diagram, together with some explanations.


Although much of the readings are too difficult for you at this level, the diagram clearly illustrates what I was trying to draw in class today.


Another note, estradiol is a form of oestrogen. For your level, you only need to know about oestrogen, thus, you can think of estradiol as oestrogen.


The diagram I reproduce here before I log off:
