Patient's question:
What are the causes of chronic follicular cysts?Doctor's answer:
Follicular cysts are caused by the following factors: There are several significant influencing factors:Related anatomical sites (1) In a normal ovarian cycle, only one follicle develops and matures, while the other growing follicles atrophy and regress sequentially during maturation. It may be due to excessive secretion of follicle-stimulating hormone (FSH) in pituitary gonadotropins or an imbalance between FSH and luteinizing hormone (LH), leading to the mature follicle not ovulating and continuing to grow, or incomplete regression of atretic follicles, where granulosa cells still secrete fluid, forming a cyst.
(2) Due to various conditions causing ovarian congestion, such as chronic pelvic inflammatory disease or ovarian ptosis, which impairs ovarian blood circulation, leading to thickening of the theca layer, preventing the mature follicle from rupturing and ovulating. The fluid within the follicle accumulates, forming a cyst.
(3) Sudden rupture of the follicular wall vessels due to certain reasons, allowing blood to enter the follicular cavity, forming a follicular hematoma. As the hematoma gradually absorbs, blood cell components dissolve and disappear, while fluid accumulates, forming a cyst.
