Endometriosis and infertility
Endometriosis is a condition in which tissue similar to the lining of the uterus is found outside the uterus, and it can affect fertility — but many women with endometriosis do become pregnant. The effect varies with the location and extent of the disease and with age. The approach is individual: in some cases monitoring/pain management, in others surgery, and in others going directly to IVF may be appropriate. There is no "one size fits all" path; the decision is made with your doctor, weighing the findings and your pregnancy goal together.
Endometriosis is a common but often misunderstood condition that brings both pain and worries about fertility. The most balanced truth is this: endometriosis can affect fertility, but many women with endometriosis become pregnant. The options, and how the decision is made, are explained below.
What is endometriosis?
Endometriosis is the growth of tissue similar to the tissue that normally lines the inside of the uterus (the endometrium) outside the uterus — for example, on the ovaries, the fallopian tubes or the lining of the abdomen (peritoneum). The form found on the ovary is sometimes called a "chocolate cyst" (endometrioma). Because this tissue responds to the menstrual cycle, over time it can create adhesions and an inflammatory environment.
How does it affect fertility?
Endometriosis can affect fertility in several ways:
- Adhesions can make it harder for the egg and sperm to meet,
- Ovarian tissue and the reserve can be affected,
- The inflammatory environment can make conditions less favorable for the egg/embryo.
The degree of the effect varies with the extent of the disease and age. With mild endometriosis, fertility may be close to normal, while with widespread disease the effect may be more pronounced. That is why the same approach is not applied to everyone.
When should it be suspected?
Endometriosis may be considered in the following situations:
- Severe menstrual pain or pain during intercourse,
- Chronic pelvic pain,
- Difficulty becoming pregnant (sometimes even without pain),
- An ultrasound appearance of a chocolate cyst on the ovary.
However, the severity of pain does not always match the effect on fertility; endometriosis can also be painless.
Options: monitoring, surgery, IVF
For women with endometriosis who want to become pregnant, the path is individual:
In mild cases and at a suitable age, a period of monitoring or pain management may be preferred.
In selected cases, removal of adhesions/endometriosis lesions may be considered; but the benefit and the possible risks (for example, to the reserve) are weighed together.
Comes to the fore especially when the reserve is affected, age is more advanced, or other approaches have not been enough.
There is no single answer that fits everyone to the question "Surgery first, or straight to IVF?" The decision is made by your doctor in light of current guidelines, taking into account age, extent, pain, reserve and any previous treatment.
Chocolate cysts and the surgery decision
For chocolate cysts on the ovary, surgery is a balancing act: on the one hand it can reduce symptoms, on the other it can affect ovarian reserve. That is why, especially for women who want to become pregnant, surgery is evaluated without rushing and individually. For the general evaluation of ovarian masses, see also: ovarian mass.
When to see a doctor
- If you have severe menstrual/pelvic pain,
- If you have been diagnosed with endometriosis and are thinking about pregnancy (early, so you can plan ahead),
- If you are having difficulty becoming pregnant (6–12 months, depending on age),
- If a chocolate cyst has been found on ultrasound.
With an accurate and individual plan, endometriosis is often a manageable condition. The healthiest approach is to discuss the options and timing with your doctor, keeping your pregnancy goal at the center.
Frequently asked questions
I have endometriosis. Can I get pregnant?
In most cases, yes. Endometriosis can make it harder to conceive, but many women with endometriosis become pregnant naturally or with treatment. The effect varies with the extent of the disease and with age. Your doctor will assess the options in your situation.
With endometriosis, should surgery or IVF come first?
This decision is individual, and there is no single right answer. Age, the extent of the disease, pain, ovarian reserve and any previous procedures are considered together. In some cases surgery is more appropriate, in others going directly to IVF. Your doctor makes the decision based on your current findings.
Does chocolate cyst surgery reduce ovarian reserve?
Some surgical procedures on the ovary can affect the reserve; that is why the decision is made carefully and individually. Especially for women who want to become pregnant, the possible benefits and harms of surgery are weighed together. This is something to discuss in detail with your doctor.
If my endometriosis doesn't cause pain, does that mean it won't affect my fertility?
The severity of pain and the effect on fertility do not always go hand in hand. In some women, endometriosis can affect fertility without noticeable pain; others have severe pain but no difficulty becoming pregnant. That is why the evaluation looks at the whole picture.
Does endometriosis lower the success of IVF?
Endometriosis can affect the process in some cases, but many women with endometriosis become pregnant with IVF. Expectations are individual and depend on age, reserve and the state of the disease. Your doctor will share a realistic assessment based on your test results.
