Ovarian cysts are fluid-filled sacs that develop on a woman’s ovary. While most are harmless and disappear on their own, understanding what triggers their formation is key to preventative care and early detection. So, what is the main cause of ovarian cyst development? In most cases, functional cysts, the most common type, arise due to normal hormonal fluctuations during the menstrual cycle.
The Menstrual Cycle’s Role: Functional Cysts
The primary culprit behind most ovarian cysts is the menstrual cycle itself. These cysts, known as functional cysts, are a natural byproduct of ovulation. Normally, an egg develops within a follicle on the ovary. This follicle ruptures, releasing the egg. However, sometimes things don’t go according to plan, leading to cyst formation. Understanding this process is crucial for grasping why functional cysts are so prevalent. There are two main types of functional cysts:
- Follicular cysts: Occur when the follicle doesn’t rupture and release the egg. Instead, it continues to grow, forming a cyst.
- Corpus luteum cysts: Develop after the egg is released. The corpus luteum, which produces hormones to support early pregnancy, can fill with fluid and form a cyst if the opening seals over.
While hormonal imbalances can contribute, functional cysts are largely a consequence of the body’s regular reproductive processes. Other contributing factors include:
- Hormonal medications: Drugs used to stimulate ovulation can increase the risk of functional cysts.
- Pregnancy: Corpus luteum cysts are common in early pregnancy and usually resolve on their own.
It’s important to note that other types of ovarian cysts exist, such as dermoid cysts, cystadenomas, and endometriomas, which have different causes. However, when considering the *main* cause of ovarian cysts overall, the hormonal activity of the menstrual cycle and subsequent functional cyst formation takes precedence.
