Dear Dr Sher,

I recently had a baseline scan and oestrogen and progesterone blood tests for an upcoming FET cycle. The scan and blood tests identified a 2.5cm hormone-producing simple cyst on my left ovary. I have been prescribed 21 days of Provera (2 x 10mg tablets daily), which I’m told usually resolves these cysts. How long does it normally take for simple cysts of this size to resolve? Is this course of Provera likely to resolve the cyst within 3 weeks?

Thank you!
