Sex Hormones In Humans
Akopọ
At puberty the body rebuilds itself, and the architects are two hormones: testosterone in boys and oestrogen in girls. The same kind of chemical messengers then run a monthly cycle in women that prepares the body for a possible pregnancy, building up the lining of the uterus and then, if no embryo arrives, clearing it away.
In this lesson you will describe what testosterone and oestrogen do at puberty, follow the menstrual cycle as changes in the ovaries and the uterus lining, and (for Extended) name where oestrogen and progesterone are made and explain how FSH, LH, oestrogen and progesterone control the cycle and early pregnancy.
