Causes of Uterine Cysts

This refers to a cystic mass arising in the female uterus. Many women are particularly curious about its cause but remain uncertain. So, what causes uterine cysts?

Causes of Uterine Cysts

Chronic inflammatory stimulation can lead to cyst formation within the uterus. Some women suffer from chronic endometritis or other forms of chronic uterine inflammation. If left untreated, prolonged inflammation may cause recurrent local tissue congestion and edema, even resulting in infiltration by inflammatory cells. This can obstruct uterine glands, preventing normal drainage of glandular secretions—and ultimately leading to cyst formation.

Fibrotic cysts of uterine tissue. Chronic inflammation within the uterus may gradually resolve, with associated edema and congestion subsiding over time. However, the previously inflamed tissue may undergo fibrosis. As this fibrotic tissue becomes covered by squamous epithelium, it severely impairs the drainage of secretions from uterine glands—potentially resulting in cyst formation. Other contributing factors include poor personal hygiene and unregulated or unsafe sexual practices, which predispose women to various gynecological infections—including cervicitis, endometritis, and vaginitis. Such infections can disrupt normal uterine gland function and secretion, thereby increasing the risk of uterine cyst development.

In fact, the pathogenesis of uterine cysts closely resembles that of acne—both result primarily from obstruction of glandular ducts. Maintaining good personal hygiene and actively preventing gynecological infections can effectively reduce the risk of developing uterine cysts. Most uterine cysts are benign and require only regular monitoring at a healthcare facility. However, patients with larger cysts may require surgical excision.
