You've probably been told at a doctor's appointment or during a scan while you were expecting a baby that you have a small cyst on your ovary. It's normal to feel a little scared when you hear that. However, this is about a condition called a Corpus Luteum Cyst, which is a benign growth that usually disappears on its own. So let's talk about it in more detail, shall we?
What is a Corpus Luteum Cyst? Simply put...
Simply put, a Corpus Luteum Cyst is a small, fluid-filled, usually harmless lump that forms inside your ovaries. It forms in a part of your body called the Corpus Luteum . Now you may be wondering what the Corpus Luteum is.
Imagine, every month, an egg is released from one of your ovaries, which we call ovulation . After that egg is released, the remaining cells in the ovary gather together to form this temporary structure called the Corpus Luteum. It's like a small wound that ruptures and new tissue forms there. This Corpus Luteum is very important, especially if you get pregnant.
This corpus luteum produces a hormone called progesterone . This hormone is very important for your uterus, because if a fertilized egg arrives and implants in the uterus and develops into an embryo, the uterus is prepared by this hormone progesterone. So, when the function of the corpus luteum is completed, it usually shrinks and fades away. However, sometimes if this corpus luteum continues to grow and fluid accumulates inside, then we form what we call a Corpus Luteum Cyst.
The important thing is that this is a common occurrence and not a serious illness.
Who gets Corpus Luteum Cyst?
Any woman who has a monthly period can develop a cyst like this. However, if you are pregnant, a doctor is more likely to find one. This is because during pregnancy, the corpus luteum lasts a little longer to support the fetus.
Most of the time, these cysts are painless. That means you may not even know you have one. They are often discovered incidentally, especially during ultrasound scans during pregnancy.
How common are these?
These so-called Corpus Luteum Cysts are actually very common. They are one of the most common growths (lumps, bumps) that doctors often see on scans, especially during the first trimester of pregnancy. So, if you have one of these, remember that it is not unusual.
Will this cyst affect my body?
Most of the time, this cyst will not affect your body in any way. If you are pregnant, it will not affect your baby either. So don't worry unnecessarily.
However, very rarely , if the cyst is large enough to damage your ovaries or to pose a risk to your pregnancy, your doctor may decide to remove it surgically. In this case, your doctor may also give you exogenous progesterone to replace the progesterone produced by the corpus luteum. But, again, this is very rare.
What are the symptoms of a Corpus Luteum Cyst?
Usually, a small cyst does not cause any symptoms. It can come and go without you noticing. However, in some cases, if this cyst bursts (rupture) , or bleeds (hemorrhagic) , or twists with the ovary (torsion) , then some symptoms may occur.
If so, you may feel things like this:
- Sudden, severe pain in the lower abdomen
- Severe nausea and vomiting
- Feeling dizzy (vertigo) or weak
If you have these symptoms, it is very important to seek medical advice immediately, as these may be conditions that require emergency treatment.
Why does this Corpus Luteum Cyst form? Let's take a closer look.
As mentioned earlier, this cyst forms when your Corpus Luteum continues to grow rather than shrinking normally, such as during pregnancy.
Let's take a look at exactly how this happens. Every month, during your menstrual cycle, an egg is released from a small sac called a follicle in one of your ovaries (ovulation). Once the egg is released, the remaining part of the follicle that released the egg becomes the Corpus Luteum.
Now, if this released egg is fertilized by a sperm, then this corpus luteum does a very important job. That is, it produces the hormone progesterone. This hormone causes the lining of your uterus to thicken. That is when a fertilized egg can implant in the uterus and develop into a healthy embryo.
If you are pregnant, this corpus luteum lasts for about 12 weeks. After that, when the placenta starts producing the hormone progesterone needed by the fetus, the corpus luteum is no longer needed, so it gradually shrinks.
However, if the egg is not fertilized, meaning you do not become pregnant, the corpus luteum usually shrinks and disappears within about 10 days. That's when you get your period.
So, if this corpus luteum fills with fluid and gets a little bigger, that's what we call a Corpus Luteum Cyst. However, most of the time, it self -resolves/reabsorbs and disappears.
How does a doctor diagnose this?
To find out if you have a Corpus Luteum Cyst, your doctor may do the following:
- Imaging: These cysts are often found with ultrasound scans. A transvaginal ultrasound can give you a very clear view of your uterus and ovaries. This involves inserting a small, thin instrument (wand) that emits sound waves through your vagina and creating an image on a computer screen using the sound waves. This allows your doctor to see if there are any lumps or cysts in your ovaries. This is a painless, simple test.
- Other Tests: Sometimes, your doctor may also check your hormone levels to understand the exact nature of the cyst.
What is the treatment for this?
Most of the time, you won't need any treatment for a Corpus Luteum Cyst. If you're pregnant, your cyst will often go away on its own during the second trimester of pregnancy. If you're not pregnant, the cyst will go away within a few weeks, usually after about three of your menstrual cycles.
In the meantime, if you have any discomfort or pain, your doctor will help you manage those symptoms. For example:
- Rest
- Pain medications
- If the pain increases, you may be advised to pause sexual intercourse for a while .
As mentioned earlier, very rarely, if the cyst is large enough to damage the ovary, or if there is a risk of pregnancy, your doctor may remove it surgically. However, it is important to remember that this is a very rare occurrence .
Can the formation of a Corpus Luteum Cyst be prevented?
No. You can't prevent these Corpus Luteum Cysts from forming. Because, they are something that happens naturally as part of your body's normal process. Every month, when you ovulate, a new Corpus Luteum is formed. Each time, there is a small chance that a cyst will form.
The good news is that you don't need to worry about preventing these types of cysts from forming, as they are harmless and normal.
What can I expect if I have a Corpus Luteum Cyst?
In fact, you shouldn't expect that having a Corpus Luteum Cyst will have any impact on your daily life. Although complications can occur with this cyst, they are very rare. So, if your doctor tells you that you have one, don't panic unnecessarily.
When should I seek medical advice about this as soon as possible?
If you are experiencing any discomfort due to this cyst, discuss it with your doctor. However, if the cyst is causing severe pain that feels like it has burst, or if it has become so large that it is twisting the ovary (ovarian torsion), it is essential to seek immediate medical attention.
Be aware of the following symptoms. If you have any of these, see a doctor immediately:
- Persistent nausea and vomiting with lower abdominal pain.
- Severe pain in the shoulder (this can sometimes be a sign of internal bleeding).
- If you feel dizzy (vertigo), your eyes are blue and you feel faint.
- A sudden, severe pain in your lower abdomen or side, like a knife stabbing you.
These warning signs are very important. But, remember, most of the time, this Corpus Luteum Cyst is a normal lump that forms without any special event, without any effect, and goes away on its own .
Will this Corpus Luteum Cyst go away on its own ?
Yes, absolutely. Corpus Luteum Cysts often go away on their own without any treatment. If you are pregnant, your cyst will likely go away on its own during the second trimester of pregnancy. If you are not pregnant, your cyst will likely shrink and go away within a few weeks of ovulation.
Does having a Corpus Luteum Cyst mean I'm pregnant?
No, that's not true. Having a Corpus Luteum Cyst doesn't necessarily mean you're pregnant. However, if you are pregnant, a doctor is more likely to find one. This is because they are often seen on scans during pregnancy. Since these cysts often don't cause symptoms, you may not even know you have one until a scan shows it.
So, if your doctor finds that you have a Corpus Luteum Cyst, please don't worry too much about it. They are harmless, and you may not even realize you have one. If your cyst is causing you any discomfort, your doctor will help you manage your symptoms until it goes away on its own .
Finally, the most important things you need to remember (Take-Home Message)
Okay, so I hope you now have a better understanding of the Corpus Luteum Cyst we talked about. Let's recap the most important things:
- These are normal: A Corpus Luteum Cyst is a fluid-filled, often harmless lump that forms in the ovaries during the menstrual cycle.
- Often asymptomatic: You may not even know you have one. Most often, these are found incidentally during scans.
- Goes away on its own : These cysts usually do not require treatment. They shrink on their own over time and are absorbed by the body.
- Does not affect pregnancy (mostly): If you are pregnant, this cyst will not harm either you or your baby (except for very rare complications).
- Seek medical advice if complications occur: If you experience symptoms such as severe lower abdominal pain, nausea, vomiting, or dizziness due to a cyst bursting, bleeding, or twisting, seek medical advice immediately.
- It's unavoidable, but don't worry: These are naturally occurring and therefore unavoidable. Also, since they are harmless, don't feel the need to avoid them.
So, if you have any more questions about this, or if your doctor tells you that you have a cyst like this, talk to your doctor about it and find out more. Don't worry, this is a common condition that many women experience.
