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: In a normal ovarian cycle, only one follicle develops and matures, while the other growing follicles atrophy and regress during the maturation process. 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. Due to various conditions that cause ovarian congestion, such as chronic pelvic inflammation or ovarian ptosis, leading to impaired ovarian blood circulation, theca layer thickening, resulting in mature follicles failing to rupture and ovulate, with fluid retention within the follicle forming a cyst. The vascular layer of the follicular wall may suddenly rupture 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.
