Hello! To make a long story short, I was put on birth control, specifically Ortho Evra, with the intetion of reducing and preventing of Ovarian Cysts, after I had one discovered in Oct 2004. (The discovered one was monitored, then it was decided to be removed in August 2005) However, it ruptured when I was going into have it removed, it was 5 cm at last measure) I also had cysts rupture in June 2005, and Oct. 2005. After discussing it with my obgyn I switched to Yasmin. At the end of last week I heard the FDA decision to add an additional warning to the amount of estrogen in the Ortho Evra patch. My questions are:
1. How does estrogen affect ovulation? 2. Would a heightened amount of estrogen cause ovarian cysts to grow, and form? 3. How is estrogen measured, by blood tests? 4. How is it estrogen levels determined, what is normal, and how is it defined? 5. Doesn't estrogen levels change through out women's monthy cycle?
Thank you for any help you can give me, I have been trying to do some research, but I don't understand all of the medical talk.

I can only answer a couple of your questions, so if no one else picks this up within a day or two I'll flag it and make sure someone else has seen it.
To answer what I can:
The use of hormonal birth control such as the brands you mentioned is to stop ovulation. The hormones in hormonal contraceptives trick the body into thinking it is pregnant, so it does not release a new egg. Therefore, since you are currently using hormonal birth control, you are not ovulating. This is why hormonal methods are often prescribed for women who have problems with ovarian cysts. Ovarian cysts (can) form after an egg is released from the ovary (my gynecologist explained this to me when I had one, so sorry if I don't have it down to an exact, but this is the general idea). If you are not releasing eggs, these cysts cannot form.
So, in relation to at least #2: a highetned level of estrogen in hormonal birth control should NOT cause ovarian cysts to form, because you shouldn't be ovulating and giving your body a chance to form cysts at all.
For the rest, sorry I can't help right off. I'll see if I can flag down another staffer who knows more.
Hope this little bit helped, at least.
(I'll also add, all these questions should be able to be answered by your gynecologist, possibly better and more specific to you than they could be here.)
