4) Now about contraception
Oral contraceptives usually contain which hormones?
FSH and LHOestrogen
and Progesterone
LH and Oestrogen
FSH and Progesterone
Good show!
Oestrogen and Progesterone are used in the contraceptive pill because they stop the production of FSH, causing the egg to stop maturing. However, if the pill contains too much oestrogen, then side-effects may occur such as changes in weight, mood and blood pressure.

5) The end is in sight
What is an advantage of having a hormonal implant rather than taking contraceptive pills?
The implant lasts forever
It is much more cheaper than the
pill
It is 100% effective
You don’t need to remember to use
the pill
You chose incorrectly
Yeah, that one was wrong.If you have the implant, you don’t need to worry about taking the pill constantly.However, the implant is NOT 100% effective and still does cost quite a lot. The implant also lasts 3 years and you will have to get another one once that time is over. Click to pick a
prize!
