Oestrogen:

Responsible for female sex organs and secondary
characteristics e.g. bodily hair and breast development.
Promotes the growth of the endometrium (lining of the
uterus).
Causes the moving of the fallopian tube towards the small
fluid-filled formation within the ovary that contains the
developing egg (follicle).

Active member

Progesterone:

Mainly responsible for preparing the body for pregnancy.
Progesterone (together with prolactin) stimulate the
breasts in preparation for milk production.
Unlike oestrogen, progesterone causes thickening of the
cervical mucus, and in so doing makes it more difficult for
sperm to penetrate.
Tends to result in a loss of water from the body, due to
the loss of salt.
Natural progesterone is destroyed in the stomach, and can
therefore not be taken orally.
Progestogens are a synthetic form of the female sex
hormone progesterone.
