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 various conditions that cause ovarian congestion, such as chronic pelvic inflammatory disease or ovarian ptosis, resulting in impaired ovarian blood supply, leading to thickening of the theca layer, so that mature follicles cannot rupture and ovulate, with fluid retained within the follicle to form a cyst. The vascular layer of the follicular wall may suddenly rupture for some reason, allowing blood to enter the follicular cavity to form a follicular hematoma. The hematoma gradually absorbs, with blood cell components dissolving and disappearing, while fluid increases and is retained to form a cyst.
