Endometriosis and Fertility: What You Need to Know

March is Endometriosis Awareness Month, an opportunity for our fertility clinic to raise awareness about this common condition that affects millions of women worldwide. Endometriosis can cause pelvic pain, heavy periods, and fertility challenges. Understanding endometriosis and fertility can help women explore infertility treatment options with confidence. This blog is for women experiencing symptoms of endometriosis, those concerned about their fertility, and anyone seeking to understand how endometriosis can impact reproductive health.

What Is Endometriosis?

Endometriosis occurs when tissue similar to the lining of the uterus grows outside the uterus, commonly on the ovaries, fallopian tubes, or other areas within the pelvis. This tissue can cause inflammation, scar tissue, and pelvic pain, and may sometimes form cysts called endometriomas.

Endometriosis affects an estimated 10% of reproductive age women worldwide, according to a study by the World Health Organization (WHO), and is a leading cause of infertility. In fact, the American Society for Reproductive Medicine (ASRM) found that infertile women are 6–8 times more likely to have endometriosis than fertile women, particularly when ovarian endometrioma, pelvic adhesions, or deep endometriosis are present. Endometriosis is a chronic condition, meaning it can persist for years and sometimes worsen over time. While it’s not life-threatening, it may impact daily life, relationships, and fertility.

What Are the Signs of Endometriosis?

Endometriosis symptoms can look different for every woman, but certain patterns are common. Many women experience painful periods that interfere with daily life or chronic pelvic pain that extends beyond menstruation. Pain during sexual intercourse is another common symptom, and some women notice bloating, fatigue, or nausea around their menstrual cycle. Difficulty conceiving or recurrent pregnancy loss can also signal the presence of endometriosis.

Symptoms can vary from month to month, and their severity doesn’t always match the extent of endometriosis. Some women with mild endometriosis may experience significant pain, while others with severe endometriosis may have few symptoms.

In addition to physical symptoms, endometriosis can also affect emotional well-being. Living with chronic pain, fatigue, and fertility challenges may cause stress, anxiety, or feelings of isolation.

It’s also important to keep in mind that endometriosis can be asymptomatic in some women. Even without noticeable pain or heavy periods, the condition may affect fertility, making early evaluation important for women planning pregnancy. Early evaluation and tailored infertility treatment at Piedmont Reproductive Endocrinology Group (PREG) in the Carolinas can help both symptomatic and asymptomatic patients maximize their chances of conceiving.

How Is Endometriosis Diagnosed?

Diagnosing endometriosis can be difficult as its symptoms often resemble those of conditions such as irritable bowel syndrome (IBS), pelvic inflammatory disease, or ovarian cysts. Women may wait months or even years before receiving a confirmed endometriosis diagnosis.

Laparoscopic surgery is considered the gold standard for diagnosing endometriosis, as this minimally invasive procedure allows doctors to directly see endometrial-like tissue, scar tissue, and adhesions. During laparoscopy, surgeons can also remove lesions to relieve symptoms and improve fertility potential.

Imaging tests, such as ultrasound or MRI, may detect larger cysts or deep endometriosis, but smaller lesions are often missed. Imaging and laparoscopic surgery not only help confirm endometriosis and assess fertility impact, but also allow careful evaluation of ovarian structures to rule out rare but possible ovarian cancer in patients with complex cysts.

What Are the Stages of Endometriosis?

The American Society for Reproductive Medicine (ASRM) staging system classifies endometriosis from minimal or mild endometriosis to moderate or severe endometriosis, helping guide treatment decisions and fertility planning.

  • Stage I – Minimal Endometriosis: Few superficial implants with little or no scar tissue. Fertility may not be significantly affected, but symptoms can still be present.
  • Stage II – Mild Endometriosis: More implants and shallow lesions with minor scar tissue. Fertility may start to be impacted in some cases.
  • Stage III – Moderate Endometriosis: Multiple deep implants, small cysts on the ovaries (endometriomas), and more extensive scar tissue or adhesions. Fertility may be more affected.
  • Stage IV – Severe Endometriosis: Large endometriomas, dense adhesions, and extensive involvement of pelvic organs. This stage is often associated with endometriosis-related infertility and may require surgical or assisted reproductive interventions.

How Can Endometriosis Affect Fertility?

Endometriosis can make getting pregnant more challenging, though pregnancy is still possible. The condition may affect fertility in several ways:

  • Scar tissue and pelvic adhesions: These can block fallopian tubes or distort pelvic anatomy, making it harder for eggs to reach the uterus. Adhesions can also restrict the movement of the ovaries and fallopian tubes, reducing the chance of natural conception.
  • Inflammation: Chronic inflammation in the pelvic area may affect egg quality, fertilization, and embryo implantation. Increased inflammatory molecules in the pelvic fluid can interfere with sperm and egg interactions, making conception more difficult.
  • Hormonal changes: Some women experience irregular ovulation or subtle hormone imbalances that can affect fertility. Conditions like luteal phase defects or luteinized unruptured follicles can prevent successful implantation.
  • Altered uterine environment: Endometriosis can impact endometrial receptivity, which may reduce the likelihood of embryo implantation.

A study published in PMC found that 30–50% of women with endometriosis experience infertility, and fecundity rates are lower compared to women without the condition. However, with proper medical support and infertility treatments from renowned fertility clinics like Piedmont Reproductive Endocrinology Group (PREG), many women with endometriosis conceive successfully.

What Fertility Treatments for Endometriosis Does PREG Offer?

At Piedmont Reproductive Endocrinology Group (PREG) in the Carolinas, we offer a range of fertility treatments tailored specifically to patients with endometriosis. Each fertility treatment plan is personalized based on your stage of endometriosis, ovarian reserve, symptoms, and reproductive goals.

Personalized Fertility Assessment

Understanding the full picture of how endometriosis affects your fertility is the first step. Our fertility specialists evaluate ovarian reserve, hormone levels, and reproductive anatomy to identify where endometriosis may be impacting your chances of conception. This thorough fertility assessment forms the foundation of your individualized treatment plan.

Medical Management

For patients where symptom control supports fertility goals, our fertility doctors use targeted medications to help manage endometriosis and create the best possible conditions for conception. Medical management is always tailored to your specific needs and coordinated with your broader fertility plan.

Assisted Reproductive Technology (ART)

For many patients with endometriosis, assisted reproductive technology (ART) offers the most direct path to pregnancy. Piedmont Reproductive Endocrinology Group (PREG) offers in vitro fertilization (IVF) and intrauterine insemination (IUI) tailored to the unique challenges endometriosis presents, such as reduced ovarian reserve, impaired implantation, and pelvic adhesions. IVF in particular, can bypass many of the anatomical and hormonal barriers endometriosis creates.

Egg Freezing

For patients who wish to delay pregnancy or are concerned about declining ovarian reserve due to endometriosis, egg freezing offers a way to preserve fertility now for use in the future. Our team can help you assess your current ovarian reserve and determine whether fertility preservation is the right step for you.

Fertility Counseling & Support

Living with endometriosis and navigating fertility treatment can take an emotional toll. Piedmont Reproductive Endocrinology Group (PREG) provides compassionate counseling and support throughout your journey, helping you feel informed, empowered, and cared for throughout the process.
