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. 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 that cause ovarian congestion, such as chronic pelvic inflammatory disease or ovarian ptosis, which impair ovarian blood circulation, leading to thickening of the capsule, preventing the mature follicle from rupturing and ovulating. The fluid contained within the follicle accumulates, forming a cyst.
(3) The vascular layer of the follicular membrane suddenly ruptures for some reason, 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.
