2) What else do you know?
At what day in the menstrual cycle is the egg released?
Day 16 Day 4
Day 14 Thursday
Congratulations!Day 1 is when the uterus lining breaks down and the bleeding starts. This lasts for about 4 days. The lining builds up again from day 4 to 14 and then the egg is released at day 14 as you know.If no fertilised egg lands on the wall by day 28, the lining breaks down again and the cycle starts again.

Why did you even pick that?...The answer was day 14!Day 1 is when the uterus lining breaks down and the bleeding starts. This lasts for about 4 days. The lining builds up again from day 4 to 14 and then the egg is released at day 14 which you SHOULD have known.If no fertilised egg lands on the wall by day 28, the lining breaks down again and the cycle starts again.

3) But do you know this one?
How do hormones during the menstrual cycle move around the body?
They don’tThey take the bus
Along the nervous system
Through the blood stream
Correctomundo!

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!
