Dear amatullah,
PCOS means polycystic
ovarian syndrome. That means that both ovaries have multiple small
cysts. Cyst just means fluid with a skin over ti - think of a blister. In PCOS, the cysts are ovarian follicles. that means , around each egg cell there is a circle of cells called follicular cells that produce hormones. Those cells help mature the egg. Every month one egg is selected to mature and to ovulate - that is to pop out of the ovary.
