The menstrual cycle last for approximately
one month and involves the release of an
egg from a woman’s ovary, and a period.
The cycle and the hormones used to control
it can be seen below.
1. MENSTRUATION (PERIOD) – uterus
2. FSH released by PITUITARY GLAND in
3. FSH makes EGG FOLLICLE grow and release
4. OESTROGEN AND PROGESTERONE thicken lining
and stops FSH (stops further eggs).
5. LH triggers EGG RELEASE
6. Follicle shrinks into a YELLOW BODY, this releases
7. PROGESTERONE makes lining
THICKEN more.

grow and mature
properly are given a
hormone to help
correct this. From
the list on the left

you think they are
given??
