The female reproductive system is a marvelous network of organs and hormones that work together to create and sustain life. One of its important structures is the corpus luteum, a temporary gland in the ovary. Sometimes, the corpus luteum can become enlarged—this is known as corpus luteum hypertrophy. In most cases, it does not cause severe problems. However, understanding this condition can help you make informed health decisions.
The corpus luteum is a temporary gland that forms in the ovary after an egg (ovum) is released during ovulation. Its name comes from Latin, meaning “yellow body,” because of its yellowish color. The main job of the corpus luteum is to produce hormones—especially progesterone, and smaller amounts of estrogen—that support a potential pregnancy.
- If pregnancy occurs: The corpus luteum keeps working, producing enough progesterone to help maintain the uterine lining and nurture the early pregnancy until the placenta takes over hormone production.
- If pregnancy does not occur: The corpus luteum naturally breaks down after about two weeks, causing hormone levels to drop, leading to menstruation.
What is Corpus Luteum Hypertrophy?
- Hypertrophy means enlargement of a cell, tissue, or organ.
- Corpus luteum hypertrophy refers to an enlarged corpus luteum. This can happen in normal situations (like early pregnancy) or due to certain conditions that affect hormone levels and ovarian function.
An enlarged corpus luteum is not always harmful. Sometimes it might be a sign of a functional cyst or an underlying condition that needs attention.
Anatomy and Pathophysiology of the Corpus Luteum
Understanding how the corpus luteum is formed and how it functions helps us grasp why it might become enlarged.
Structure
- The corpus luteum develops in the ovary from the follicle that released the egg.
- After ovulation, the remaining follicle cells transform into luteal cells (also known as granulosa lutein and theca lutein cells).
- These luteal cells grow, fill with lipids (fats), and change color to yellowish. The size can vary, but typically, the normal corpus luteum is about 1-2 cm in diameter.
Blood Supply
- The corpus luteum has a rich blood supply from ovarian arteries and branches of the uterine artery.
- Proper blood flow is essential for delivering the cholesterol needed to produce hormones like progesterone.
Nerve Supply
- The ovaries, including the corpus luteum, receive nerve signals mainly through the pelvic plexus and some sympathetic and parasympathetic fibers.
- While the nerve supply helps regulate blood flow and hormone release, the corpus luteum’s function is largely controlled by hormonal signals from the brain (the hypothalamus and pituitary gland).
Functions of the Corpus Luteum
- Progesterone Production: Maintains the uterine lining (endometrium) to support early pregnancy.
- Estrogen Production: Works alongside progesterone to regulate the menstrual cycle and support pregnancy.
- Support for Early Pregnancy: If fertilization occurs, the corpus luteum ensures the uterus is ready to receive and nurture the fertilized egg.
Pathophysiology of Corpus Luteum Hypertrophy
- When hormone signaling is disrupted or unusually stimulated, the corpus luteum might enlarge abnormally.
- In early pregnancy, human chorionic gonadotropin (hCG) from the embryo can cause the corpus luteum to grow larger to produce more progesterone, which is normal.
- In other situations, hormonal imbalances (for example, high levels of luteinizing hormone or certain medications) can lead to excessive growth of the luteal cells.
Types of Corpus Luteum Hypertrophy
Although not always strictly categorized, we can consider the following broad types or situations in which the corpus luteum becomes enlarged:
Normal Physiological Hypertrophy
- Occurs in early pregnancy.
- Often harmless and resolves on its own.
Functional Corpus Luteum Cyst
- Formed when the corpus luteum seals itself off and fills with fluid or blood.
- Might cause discomfort or pain but can also resolve naturally.
Hemorrhagic Corpus Luteum Cyst
- Occurs when bleeding happens within the corpus luteum.
- Can cause acute pelvic pain and might require medical attention.
Pathological Hypertrophy
- Related to hormonal imbalances, certain ovarian disorders, or side effects of fertility treatments.
- May need further investigation and possible treatment.
Possible Causes of Corpus Luteum Hypertrophy
- Normal Early Pregnancy
- Hormonal Imbalances (e.g., excess luteinizing hormone)
- Use of Fertility Medications (e.g., clomiphene citrate, hCG injections)
- Polycystic Ovary Syndrome (PCOS)
- Stress (altering hormone levels)
- Thyroid Disorders (hypothyroidism or hyperthyroidism)
- Obesity (affects hormone production and metabolism)
- Extreme Exercise (may disrupt normal menstrual cycles)

A: No. Sometimes it is a normal response, especially in early pregnancy. However, if symptoms are severe or persistent, medical evaluation is important.Q: Can I still get pregnant if I have an enlarged corpus luteum?
A: Yes. The corpus luteum’s main role is to support early pregnancy. Many women with an enlarged corpus luteum conceive successfully, especially if the enlargement is functional and not due to a harmful cause.Q: How long does a corpus luteum cyst last?
A: In many cases, a corpus luteum cyst can resolve on its own within a few weeks or a couple of menstrual cycles.Q: What does pain from corpus luteum hypertrophy feel like?
A: It can range from mild discomfort to sharp, stabbing pain, often localized to one side of the lower abdomen.Q: Do birth control pills help shrink an enlarged corpus luteum?
A: Sometimes, hormonal contraceptives may help regulate the menstrual cycle and reduce the likelihood of forming new cysts.Q: Can stress really cause corpus luteum hypertrophy?
A: Chronic stress can contribute to hormonal imbalances, which may indirectly lead to ovarian changes, including corpus luteum enlargement.Q: How is corpus luteum hypertrophy different from PCOS?
A: PCOS involves multiple cysts in the ovaries and is a chronic hormonal disorder. Corpus luteum hypertrophy is often a temporary condition, typically involving just one enlarged cyst at a time.Q: Is surgery always required for corpus luteum hypertrophy?
A: No. Surgery is often a last resort and is usually reserved for complications or when there is suspicion of malignancy or severe bleeding.Q: What happens if a corpus luteum cyst bursts?
A: If it ruptures, you might experience sudden, severe pain and, in some cases, internal bleeding. Seek medical help if you suspect rupture.Q: Can a corpus luteum cyst reoccur?
A: Yes. It can reoccur, especially if underlying hormonal imbalances are not addressed.Q: Are there any natural supplements to help with corpus luteum hypertrophy?
A: Some women find relief with supplements like vitamin D, magnesium, and omega-3 fatty acids, but always consult your doctor first.Q: Can an enlarged corpus luteum cause infertility?
A: Generally, it does not cause infertility by itself. However, if the hypertrophy is part of a larger hormonal issue, it might affect fertility indirectly.Q: How do doctors tell the difference between an enlarged corpus luteum and an ovarian tumor?
A: Imaging tests such as ultrasound or MRI, along with blood tests (e.g., CA-125), can help distinguish between benign cysts and tumors.Q: Will I feel pain during sexual intercourse if I have corpus luteum hypertrophy?
A: Some women do experience pain or discomfort, especially if the cyst is large or if there’s associated inflammation.Q: Does corpus luteum hypertrophy happen after menopause?
A: It is very rare after menopause because ovulation stops, and the corpus luteum no longer forms. If you have ovarian cysts after menopause, they require medical evaluation.
