About 30 to 50% of patients who are diagnosed with endometriosis have infertility issues or problems to get pregnant.
The various sections of this article are assembled in the following table of contents.
Causes of infertility
The ovaries and the Fallopian tubes are damaged mainly by the growth of endometrial implants in places other than the uterus.
In the ovary, adhesions destroy the healthy tissue, which affects the ovarian reserve directly, complicates the normal development of follicles, and prevents the maturation of eggs. Moreover, endometrial cysts can prevent ovulation as well.
When endometriosis is located on the Fallopian tubes, it can compromise tubal patency. This is a barrier for the journey of the egg through the tube after being released from the ovary. As a consequence, fertilization and therefore pregnancy never take place.
Diminished endometrial receptivity
Infertility can be a consequence of immunological alterations. The levels of IgG and IgA antibodies, as it happens with lymphocytes, appear increased on blood, which may affect endometrial receptivity and embryo implantation.
The embryo’s ability to implant to the uterus can be compromised because endometriosis causes patients trouble to synthesize endometrial tissue. Moreover, the levels of integrins (cell adhesion molecules that take part in the implantation process) are too low.
Getting pregnant naturally
The most advisable option for women with endometriosis to recover their fertility and have the possibility of having children naturally is to undergo medical or surgical treatment. Choosing one option or the other depends on the severity of endometriosis and the history of each patient.
We can classify endometriosis into four stages or grades depending on the location, quantity, profundity, and size of the endometrial implants:
- Stage 1 or minimal disease
- Stage 2 or mild disease
- Stage 3 or moderate disease
- Stage 4 or severe disease
Painkillers and hormonal treatments are effective to relief the pain and regulate the menstrual cycles. However, laparoscopic surgery is likely to be required in order to improve the woman’s fertility and increase her chances of conceiving.
So, in short, these treatments are effective in achieving a natural pregnancy in cases of mild-to-moderate endometriosis.
Laparoscopic surgery, also known as minimally invasive surgery (MIS), bandaid surgery, or keyhole surgery, involves inserting a laparoscope through a small incision to observe the abdominal cavity.
Stage IV or severe endometriosis, especially when endometriomas or ovarian cysts (also called chocolate cysts) are found, can be treated with a technique known as laparoscopic cystectomy to remove this type of cysts. This helps increase the pregnancy success rates.
Endometriosis & fertility treatments
If you have undergone surgery and have been trying to conceive for one year without luck, the good news is that fertility treatments can be the best option for you to start a family.
Depending on the severity of endometriosis and the progress of other treatments, the most adequate options may be, from the simplest to the most challenging:
Intrauterine Insemination (IUI)
IUI is the option of choice in younger patients with mild-to-moderate endometriosis (stages I and II).
The hormones used to induce ovulation improve the prognosis of these patients. However, for IUI to be effective in achieving pregnancy, tubal patency is required so that the sperm is able to hit the egg.

In Vitro Fertilization (IVF)
IVF is an option for patients affected with stage III or IV endometriosis. It is also recommended when IUI has failed in women with stage I-II endometriosis.
The pregnancy rates of IVF are higher than those of IUI in women with endometriosis. Specialists recommend, however, that these women give IUI a try on the first attempt as long as they meet the requirements to be referred to IUI.

It has been proved after several analyses at IVF lab that the morphology of eggs and embryos from women with endometriosis is poorer. Moreover, the fertilization rates and subsequent embryo development rates are lower.
For this reason, women with severe endometriosis, or those who have been through various failed IVF cycles, have no alternative but to use donor eggs to have a baby. In fact, 10% of donor egg recipients are endometriosis patients.
Eggs from young, healthy women have an excellent morphology. For this reason, we can only expect high success rates, irrespective of whether the recipient is a woman with endometriosis or not.
Using donor eggs is also indicated when ovarian endometriomas make it difficult for the specialist to retrieve the eggs from the ovary through follicle puncture. See also: What’s Being an Egg Donor Recipient Like?
In the most severe cases of endometriosis (stage IV) the hormones used to trigger the production of multiple eggs can promote the growth of endometrial implants, thereby making it impossible for the woman to bear a full-term pregnancy.
In such cases, surrogacy may be the only option to have baby. Learn more: What Is Surrogacy & How Does It Work? – Everything You Should Know.
Given that endometriosis is a progressive disease and, what’s more, the biological clock is ticking non-stop, women diagnosed with endometriosis are strongly recommended to preserve their fertility by means of egg vitrification in order not to miss their chance of having children in the future.
It allows egg quality to be retained, thereby reaching better IVF success rates. Moreover, it should be taken into account that endometriosis affects the ovarian reserve as well.
FAQs from users
Can you get pregnant with endometriosis without surgery?
Unfortunately, the chances are very low. While painkillers or hormonal treatments can help relieve the symptoms of endometriosis, laparoscopic surgery is necessary to achieve pregnancy with endometriosis, even in mild-to-moderate cases.
Can you get pregnant with untreated endometriosis?
As explained earlier, it is highly unlikely. Endometriosis should be properly managed by means of laparoscopic surgery.
What are the chances of getting pregnant with one tube and endometriosis?
The odds of falling pregnant with one Fallopian tube should not be different than any other woman as long as the remaining tube is working normally. Depending on the stage of endometriosis, you may need IVF to get pregnant.
What are the dangers of being pregnant with endometriosis?
Several studies have indicated that endometriosis is a risk factor for complications during pregnancy. Your doctor should advise you on the potential risks associated according to the severity of your endometriosis.
The risks associated with pregnancy in women with endometriosis include increased risk of miscarriage, ectopic pregnancy, placenta displacement, spontaneous rupture of the uterus, obstructed labor, postpartum hemorrhage, and preterm birth.
How does pregnancy help endometriosis?
No, pregnancy does not cure endometriosis. Although it is a widespread myth, it is actually true that pregnancy may temporarily suppress the symptoms of endometriosis. However, this does not mean that it eradicates the disease itself.
