I wrote the same, :/ do you reckon we would get at least one out of the three?


The thing is that in previous exam questions they have linked progesterone to inhibiting FSH in contraceptives. Its question 3) b) i) on the June 2012 paper? (http://filestore.aqa.org.uk/subjects/AQA-BIOL5-QP-JUN12.PDF)

Which makes me think that what we wrote is justified?? :s-smilie:

Progesterone inhibits FSH but Oestrogen does too.
Both answers could, and should, be justified as:
With Oestrogen - the follicles that release oestrogen are destroyed, and therefore it does not release oestrogen, therefore not inhibiting the release of FSH.
With Progesterone - the follicles are destroyed, therefore preventing ovulation, preventing the formation of the corpus luteum, and therefore progesterone is not released, so it doesn't inhibit FSH release.
