Ovarian cysts are a common occurrence in women of reproductive age. These fluid-filled sacs can develop for various reasons and often resolve on their own without causing any symptoms or complications. However, in some cases, ovarian cysts may be associated with menstruation, leading to menstrual-associated ovarian cysts. In this article, we will delve into the details of these cysts, including their causes, symptoms, diagnosis, and treatment options.
What are Menstrual-Associated Ovarian Cysts?
Menstrual-associated ovarian cysts, also known as functional ovarian cysts, are cysts that develop as a result of the normal menstrual cycle. These cysts typically form when an egg follicle fails to rupture and release an egg during ovulation. Instead, the follicle continues to grow, forming a fluid-filled sac on the ovary. Menstrual-associated ovarian cysts are usually benign and do not increase the risk of ovarian cancer.
Causes and Risk Factors:
The precise cause of menstrual-associated ovarian cysts is not fully understood. However, several factors may contribute to their development, including hormonal imbalances, excessive production of estrogen, and alterations in the normal process of follicle development and ovulation. Other risk factors for developing these cysts include a history of previous ovarian cysts, irregular menstrual cycles, polycystic ovary syndrome (PCOS), and certain fertility medications.

Symptoms:
Most menstrual-associated ovarian cysts do not cause noticeable symptoms and are often discovered incidentally during routine gynecological examinations or imaging tests. However, if the cyst grows larger or becomes twisted (ovarian torsion), it can lead to symptoms such as:
- Pelvic pain or discomfort: Dull or sharp pain in the lower abdomen or pelvic region, which may be intermittent or persistent.
- Menstrual irregularities: Changes in menstrual flow, including heavier or lighter periods, irregular periods, or spotting between periods.
- Pain during sexual intercourse: Discomfort or pain during sexual activity (dyspareunia).
- Bloating or pressure: A sensation of fullness or bloating in the abdomen.
Diagnosis:
If menstrual-associated ovarian cysts are suspected, the healthcare provider will typically perform a thorough medical history assessment, physical examination, and may order additional tests, including:
- Ultrasound: Transvaginal or abdominal ultrasound can help visualize the cyst and determine its characteristics, such as size, location, and appearance.
- Blood tests: Hormonal levels, including follicle-stimulating hormone (FSH), luteinizing hormone (LH), and estrogen, may be measured to assess ovarian function and hormone imbalances.
Treatment Options:
In most cases, menstrual-associated ovarian cysts do not require treatment and resolve on their own within a few menstrual cycles. However, if the cyst causes severe pain, grows larger than usual, persists for more than a few months, or appears suspicious, the healthcare provider may recommend one of the following treatment options:
- Watchful waiting: Regular monitoring of the cyst through follow-up ultrasounds to ensure it resolves spontaneously.
- Pain management: Over-the-counter pain relievers like ibuprofen or prescribed pain medications may help alleviate discomfort.
- Hormonal contraceptives: Birth control pills or hormonal contraceptives can help regulate hormone levels and prevent the formation of new cysts.
- Surgical intervention: If the cyst is large, persists, causes severe symptoms, or poses a risk of ovarian torsion, surgical removal (cystectomy) may be necessary. In some cases, the entire ovary may need to be removed (oophorectomy).
Conclusion:
Menstrual-associated cysts are a common occurrence in women and are usually harmless. While most cysts resolve on their own, it is essential to monitor their growth and be aware of any associated symptoms. If you experience persistent or severe pain, changes in menstrual patterns, or other concerning symptoms, consult a healthcare provider for proper evaluation and guidance. With timely diagnosis and appropriate management, most menstrual-associated ovarian cysts can be effectively treated, ensuring optimal reproductive health and well-being.
