Testosterone
FSH function
Stimulates egg development and oestrogen secretion

Uterus
Womb- where foetus develops
Cervix
Entrance to uterus
Vagina
Where sorry is received during inter course and babies pass through during birth
Contraceptive pill
Contains progesterone or oestrogen and lowers egg maturation and ovulation so that fertilisation doesn’t happen
Contraceptive implant
Releases progesterone
Contraceptive patch
Releases oestrogen and progesterone
Infertility
Caused my low FSH levels
Egg can’t mature
Less oestrogen
Less progesterone
IVF
Fertility drugs used to make eggs Eggs collected from ovaries Eggs and sperm mixed in Petri dish Embryos develop in Petri dish Embryos checked and healthy ones are implanted into uterus
Days 1-5 in menstrual cycle
Womb lining breaks down (period)
Days 6-10 in menstrual cycle
