Endometriosis is a chronic and painful gynecological disease characterized by the growth of cells similar to those lining the inside of the uterus (endometrium) outside the uterus, typically in the pelvic region (such as on the ovaries, fallopian tubes, intestines, or bladder surface). Also commonly known as chocolate cysts, this condition can seriously affect women's fertility. As Prof. Dr. Mehmet Çınar, at our Ankara IVF Center, we adopt a comprehensive approach to understand the complex relationship between endometriosis and infertility and to offer couples the most suitable treatment methods. In this article, we will discuss what endometriosis is, how it affects fertility, diagnostic methods, and the role of surgery and endometriosis IVF treatment.
What is Endometriosis and What are its Symptoms?
Endometriosis is a condition where tissue similar to the lining of the uterus is found outside the uterus. This tissue reacts to hormonal changes, bleeding each menstrual cycle, but because it is outside the uterus, there is no way for this blood to exit the body. This leads to inflammation, scar tissue formation, and adhesions. Endometriosis foci occurring on the ovaries are called "chocolate cysts" (endometriomas) because the old blood accumulation inside them has a chocolate-like color and consistency.
The symptoms of endometriosis can vary greatly from person to person. Some women experience severe pain, while others may have no symptoms at all, and the condition might be incidentally discovered during infertility investigations. The most common symptoms include:
- Severe Menstrual Pain (Dysmenorrhea): Pain that starts during menstrual periods and worsens over time, restricting daily activities.
- Chronic Pelvic Pain: Constant or intermittent lower abdominal and pelvic pain that persists even outside the menstrual period.
- Painful Intercourse (Dyspareunia): Pain felt especially during deep penetration.
- Painful Defecation or Urination: May occur when endometriosis affects the bowel or bladder.
- Heavy Menstrual Bleeding (Menorrhagia) or Irregular Bleeding.
- Fatigue: A common complaint due to chronic pain and inflammation.
- Infertility: Difficulty achieving pregnancy can be the first symptom of endometriosis for many women.
How Does it Affect Fertility?
Endometriosis can negatively affect female fertility through various mechanisms. These effects can vary depending on the stage and location of the disease, but even mild endometriosis can cause infertility:
- Anatomical Distortions: Endometriosis lesions and associated adhesions can cause blockages or kinking of the fallopian tubes, preventing the egg and sperm from meeting. They can also restrict the mobility of the ovaries, making it difficult for the egg to reach the tubes.
- Impact on Ovarian Reserve: The chocolate cyst (endometrioma) formed in the ovaries can damage ovarian tissue, reducing ovarian reserve and negatively affecting egg quality.
- Inflammation and Peritoneal Environment Changes: Endometriosis triggers a chronic inflammatory response in the pelvic cavity. This inflammation leads to the release of substances (cytokines, prostaglandins) that can impair egg maturation, fertilization, and embryo development.
- Implantation Problems: The presence of endometriosis lesions in the uterus (adenomyosis) can make it difficult for the embryo to implant in the uterus.
- Hormonal and Immunological Imbalances: Endometriosis can affect the body's hormonal balance and immune system, disrupting reproductive functions.
Diagnosis Methods
The diagnosis of endometriosis begins with an evaluation of symptoms, physical examination, and various imaging methods. However, a definitive diagnosis is usually made surgically.
- Patient History and Physical Examination: The doctor will thoroughly inquire about the types of pain the patient experiences, menstrual cycle, pain during intercourse, and other symptoms. Tenderness or masses in the uterus and ovaries may be felt during a pelvic examination.
- Imaging Methods:
- Ultrasonography: Used especially to detect chocolate cysts (endometriomas) in the ovaries and sometimes deeply infiltrating endometriosis lesions. Transvaginal ultrasound is the most commonly used and effective method.
- Magnetic Resonance Imaging (MRI): Can provide more detailed information and help determine the location and extent of deeply infiltrating endometriosis lesions.
- Blood Tests: CA-125 levels may be elevated in some women with endometriosis, but this test alone is not sufficient for diagnosis and can generally give an idea about the severity of the disease.
- Laparoscopy: The gold standard method for the definitive diagnosis of endometriosis. Laparoscopy involves making a small incision in the abdomen and inserting a thin camera (laparoscope) to directly examine the pelvic organs. This allows visualization of endometriosis lesions, determination of their stage, and if necessary, biopsy. Treatment can also be performed during the same session.
Surgery or IVF?
When deciding whether to opt for surgical intervention or endometriosis IVF treatment for endometriosis and infertility, a personalized approach is taken, considering many factors such as the patient's age, severity of the disease, duration of infertility, ovarian reserve, and previous treatment history.
Surgical Treatment
Endometriosis surgery is usually performed using the laparoscopic method. Surgical intervention may be considered in the following situations:
- Severe Pain Management: Removal of endometriosis lesions can alleviate pain, especially in cases of chronic pelvic pain, menstrual pain, or pain during intercourse that does not respond to medication.
- Large Chocolate Cysts: In the presence of chocolate cysts (endometriomas) larger than 3-4 cm in the ovaries, removal of the cyst may be considered. However, it should be remembered that such surgeries can have negative effects on ovarian reserve.
- Correction of Anatomical Distortions: Blockages in the tubes or severe adhesions may be attempted to be surgically removed.
The role of surgery in infertility treatment is controversial. In young patients with mild to moderate endometriosis and no other infertility factors, the chance of natural pregnancy may increase after surgery. However, in advanced-stage endometriosis or in patients with low ovarian reserve, surgery may not significantly increase the chance of natural pregnancy and may even carry the risk of further reducing ovarian reserve. Therefore, the decision for surgery should be made carefully.
IVF Treatment
Endometriosis IVF treatment is one of the most effective treatment methods, especially for infertility associated with moderate and advanced-stage endometriosis. IVF treatment bypasses many infertility factors caused by endometriosis (tubal blockage, egg-sperm interaction problems, fertilization problems). At our Ankara IVF Center, this treatment plays an important role in helping couples achieve their dream of having children.
IVF treatment may be considered a priority in the following situations:
- Advanced Stage Endometriosis: In cases where the chance of natural pregnancy is very low due to severe endometriosis or widespread adhesions.
- Failure After Surgery: In cases where pregnancy is not achieved after surgery.
- Low Ovarian Reserve: Especially in women with reduced ovarian reserve due to chocolate cysts, IVF may be preferred to utilize the remaining eggs most efficiently.
- Other Infertility Factors: When there are additional problems such as male factor infertility or unexplained infertility.
- Advanced Age: As a woman's age advances, it is important to proceed with the most effective treatment without losing time.
In IVF treatment, the steps include egg retrieval, fertilization of eggs with sperm in a laboratory environment (usually using the intracytoplasmic sperm injection (ICSI) method), and transfer of the resulting embryos to the uterus. In patients with endometriosis, ovarian stimulation protocols and embryo transfer strategies are optimized according to the characteristics of the disease. Additionally, embryo or egg freezing options are available for patients who wish to preserve their future chances of pregnancy.
When deciding on treatment, the guidance of an experienced specialist like Prof. Dr. Mehmet Çınar is critically important. Since each patient's situation is different, creating a personalized treatment plan increases the chances of success. Sometimes, surgery and IVF treatment can be combined; for example, IVF treatment may follow the surgical removal of a large chocolate cyst.
Endometriosis and infertility are complex conditions that affect women's quality of life and their dreams of having children. However, thanks to advancements in modern medicine and reproductive technologies, it is possible to overcome these challenges. As the Ankara IVF Center, we offer personalized, scientifically based, and hopeful treatment approaches to each of our patients. Remember, with the right diagnosis and a personalized treatment plan, it is possible to achieve your dreams.
