Endometriosis and Pregnancy: Important Considerations

Endometriosis is a gynecological condition in which the lining of your uterus, the endometrium, grows outside of your womb. This means you can develop scarring or extra tissue on reproductive organs, making conceiving difficult.
Most women with endometriosis go on to have a completely normal pregnancy and birth. The fertility specialists at the California Center for Reproductive Health, with locations in Encino, Valencia, Alhambra, and West Hollywood, California, can help you overcome the fertility challenges associated with endometriosis.
Here’s what we want you to know about pregnancy and endometriosis.
What is endometriosis?
The endometrium is the tissue that lines the uterine. When endometrial cells grow in other parts of your body, they function just like the tissues within your uterus. They grow and shed every month in conjunction with your menstrual cycle.
Endometriosis is a major cause of pelvic pain, heavy and irregular periods, and pain during intercourse. Endometriosis can also cause infertility. About 30-50% of women with endometriosis experience infertility.
Why does endometriosis affect fertility?
Endometriosis doesn’t always interfere with conception; many women with the condition get pregnant naturally.
But, severe endometriosis can block the ovaries or fallopian tubes or cause them to not work properly. Women with mild endometriosis sometimes have trouble conceiving, too. That’s likely because the inflammation caused by the irregular endometrial cells causes a hormonal imbalance.
Will my pregnancy be affected?
If you get pregnant normally, endometriosis shouldn’t complicate your pregnancy. You may not even need extra monitoring as your pregnancy isn’t considered high risk.
However, in some women with endometriosis, high blood pressure or bleeding can develop later in pregnancy. If you’re under our care, we’ll monitor you for these potential complications.
Endometriosis also increases the risk, albeit slightly, that your baby will be born earlier than usual or will be smaller than usual.
How does pregnancy affect endometriosis?
While you’re pregnant, endometriosis and its associated symptoms usually improve. But, pregnancy doesn’t cure the condition. Endometriosis returns after you deliver and may complicate future attempts to conceive.
There is no cure for endometriosis, and the exact reason some women develop it isn’t fully understood.
What treatments are available if endometriosis is making it hard for me to get pregnant?
Endometriosis is only one aspect of fertility that our team at the California Center for Reproductive Health considers when helping you conceive. We’ll also consider your age, how long you’ve been trying to get pregnant, any male infertility factors, what infertility interventions you’ve undergone, the stage of your endometriosis, and your family history.
Minimally invasive surgery to remove endometrial tissue that’s interfering with conception is an option. This can help you get pregnant, but doesn’t mean endometriosis won’t come back after you’ve given birth.
Assisted reproductive technologies, like in vitro fertilization and embryo transfer, are also very successful in helping women with endometriosis who are struggling to get pregnant.
If you have endometriosis and it’s interfering with your ability to get pregnant, reach out to us at the California Center for Reproductive Health. Our advanced fertility treatments help thousands of couples have healthy babies. Call the nearest location or use this website to request a consultation.

FAQ
Reproductive endocrinology and Infertility is a sub-specialty of Obstetrics and Gynecology. In addition to managing medical and surgical treatment of disorders of the female reproductive tract, reproductive endocrinologist and infertility (REI) specialists undergo additional years of training to provide fertility treatments using assisted reproductive technology (ART) such as in vitro fertilization.
Reproductive endocrinologists receive board certification by the American Board of Obstetrics and Gynecology in both Obstetrics and Gynecology and Reproductive Endocrinology and Infertility.
In general, patients should consider consulting with an REI specialist after one year of trying unsuccessfully to achieve pregnancy. The chance of conceiving every month is around 20%, therefore after a full year of trying approximately 15% of couples will still not have achieved a pregnancy.
However, if a woman is over the age of 35 it would be reasonable to see a fertility specialist earlier, typically after 6 months of trying.
Other candidates to seek earlier treatment are women who have irregular menses, endometriosis, fibroids, polycystic ovary syndrome (PCOS), women who have had 2 or more miscarriages, or problems with the fallopian tubes (prior ectopic pregnancy).
Approximately 1/3 of the time cause for infertility is a female factor, 1/3 of the time a male factor, and the remaining 1/3 a couples’ factor.
At CCRH, we emphasize the importance of establishing a correct diagnosis. Both partners undergo a comprehensive evaluation including a medical history and physical exam.
Furthremore, the woman’s ovarian reserve is assessed with a pelvic ultrasound and a hormonal profile. A hysterosalpingogram (HSG) will confirm fallopian tube patency and the uterine cavity is free of intracavitary lesions. A semen analysis is also obtained to evaluate for concentration, motility, and morphology of the sperm.
Additional work up is then individualized to direct the best possible treatment option for each couple.
In vitro fertilization (IVF) is the process that involves fertilization of an egg outside of a woman’s body.
The process starts with fertility drugs prescribed to help stimulate egg development. In your natural cycle, your body is only able to grow one dominant egg, but with stimulation medication we can recruit multiple eggs to continue to grow. After about 8-10 days of stimulation, the eggs are surgically retrieved and then fertilized with sperm in a specialized laboratory. Fertilized eggs are then cultured under a strictly controlled environment within specialized incubators in the IVF laboratory for 3-5 days while they develop as embryos. Finally, embryos (or an embryo) are transferred into the uterine cavity for implantation.
Before deciding if IVF is the right choice, it’s important to sit down with an REI specialist to discuss available treatment options. For some people, other methods such as fertility drugs, intrauterine insemination (IUI) may be the best first choice treatment. At CCRH, we believe each individual couple is unique and not everyone needs IVF.
While not painful, the fertility medications may some side effects including headaches, hot flashes, mood swings, and bloating. The injection sites may also bruise.
Unfortunately, no. Many people think once they start IVF it’s a matter of time that they will be pregnant and have a baby. But according to national statistics per the Society of Assisted Reproduction (SART), on average 40% of assisted reproduction cycles achieve live births in women under age 35. The chances of success then continue to decrease with advancing age.
At CCRH, we employ only evidence-based interventions to ensure patient safety and optimal outcome. While we cannot guarantee a baby, we guarantee that you will receive the best, most advanced, personalized care to help you maximize your chance of a baby.
The average IVF success rate (success measured in live birth rate) using one’s own eggs begins to drop around age 35 and then rapidly after age 40. This is due to the decline in egg quantity and egg quality as a woman ages.
Our clinic’s success rate consistently beats the national average year after year.
Individual insurance plans often do not have any coverage for infertility treatments. If you have a group plan, you can call members services to see if they have coverage for infertility (including consultation/workup and IVF).
