What are ovarian cysts?
Ovaries play an important role in the female reproductive system. Women have two ovaries on either side of their uterus, each the size and shape of an almond. Eggs (or ova) develop in the ovaries and are released in monthly cycles.
Symptoms of ovarian cysts
Most ovarian cysts are harmless, don’t cause any symptoms, and go away on their own. However, some types of cysts — especially large ones — may cause:
Types of ovarian cysts
There are two types of ovarian cysts: those that are related to your regular monthly cycle and those that are unrelated.
Related to your menstrual cycle
Your ovaries grow follicles on them every month. When a follicle continues to grow, it becomes what’s known as a functional cyst. There are two kinds of functional cysts:
Follicular cysts, formed when follicles (the tiny sac in which an egg grows) don’t break open to release the egg, causing the follicle to grow into a cyst
Corpus luteum cysts, formed after the follicle releases the egg and the empty follicle sac doesn’t shrink
Unrelated to your menstrual cycle
Other types of ovarian cysts aren’t related to the function of your menstrual cycle. These include:
Causes of ovarian cysts
The following are causes of ovarian cysts:
Whether they occur naturally or are brought on by taking certain fertility drugs to help you ovulate, hormonal irregularities may be the cause of your ovarian cysts.
It’s normal for an ovarian cyst to develop near the beginning of pregnancy to provide support until the placenta forms. If the cyst stays on the ovary until later stages of pregnancy, it may need to be removed.
Endometriosis is a painful condition that causes cells to grow outside of the uterus. People with endometriosis can develop a kind of ovarian cyst called an endometrioma, which can cause pain during sex and your period.
Severe pelvic infections
In some cases, pelvic infections can spread to your ovaries and cause cysts to form.
Diagnosing ovarian cysts
Your doctor can usually find out whether you have an ovarian cyst by performing a pelvic exam. To find out the type or size of cysts and whether or not they will require treatment, your doctor might perform other tests, such as:
Treatments for ovarian cysts
In the majority of cases, ovarian cysts don’t require any treatment because they go away on their own within a few months. Whether or not your ovarian cyst requires treatment depends on several factors:
- Its size
- Whether you’re experiencing symptoms
- Whether you’ve been through menopause
A laparoscopy is the most common procedure for removing ovarian cysts. In this type of surgery, the surgeon makes small cuts in your abdomen and blows gas into your pelvis to access your ovaries. Then, the surgeon inserts a laparoscope (a small tube-like microscope) into your abdomen to get a good view of the cyst. By making small cuts, the surgeon removes the cyst and then stitches you back up.
Your doctor may recommend a laparotomy if your cyst is large or there is a chance that it’s cancerous. During this procedure, the surgeon makes a large cut in the abdomen. The surgeon then removes the entire cyst and sends it to a lab for testing. If you have this procedure, you may need to stay in the hospital for a few days.
