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 the atretic follicle, with granulosa cells still secreting fluid to form a cyst. Due to ovarian congestion caused by various conditions, such as chronic pelvic inflammatory disease or ovarian ptosis, resulting in impaired ovarian blood supply, leading to thickening of the capsule, preventing the mature follicle from rupturing and ovulating, with fluid retention within the follicle forming a cyst. The vascular layer of the follicular membrane suddenly ruptures for some reason, allowing blood to enter the follicular cavity to form a follicular hematoma. The hematoma gradually absorbs, blood cell components dissolve and disappear, and fluid accumulates to form a cyst.
