The ovaries form new cysts every cycle
Thanks for writing back.
Every cycle hundreds of follicles are recruited and grow. It is a race to see which is the dominant follicle. That follicle ovulates, which is an opening of the cyst to release an egg. Then the cyst bed makes progesterone
so the uterine lining can mature (and if no pregnancy
hormone) mature and shed in a menses. So cysts occur every cycle and disappear mid cycle in a normal aproximately monthly cycle.
Perimenopausally hormones don't ebb and flow. They roller coaster up and down. Some cysts form, sometimes multiple cysts
, sometimes they regress without maturing, etc etc. But in your case, I don't think any ultrasound
is needed and if you want to do it anyway, the least chance of any cyst is right after menses. But only a normal menses, which will become rarer and rarer closer to menopause
. The more you look the more you will see cysts come and go
