Infertility in Stage I and II Endometriosis: Evaluation and Treatment

Mild endometriosis—classified as Stage I or II by the ASRM (American Society for Reproductive Medicine)—is often underestimated. Yet, even in these early stages, endometriosis can significantly affect a woman’s ability to conceive. Patients frequently experience frustration when standard exams show “normal results,” but they still struggle with unexplained infertility. How Can Mild Endometriosis Affect Fertility? …

Mild endometriosis—classified as Stage I or II by the ASRM (American Society for Reproductive Medicine)—is often underestimated. Yet, even in these early stages, endometriosis can significantly affect a woman’s ability to conceive. Patients frequently experience frustration when standard exams show “normal results,” but they still struggle with unexplained infertility.

How Can Mild Endometriosis Affect Fertility?

Even without ovarian endometriomas or tubal blockages, minimal or mild endometriosis can disrupt:

Ovulation and oocyte quality

Fallopian tube function and ovum transport

Embryo implantation, due to inflammatory changes in the pelvic environment

Subtle pelvic adhesions, which may hinder fertilization and embryo migration

These effects are driven by chronic inflammation, oxidative stress, and the release of cytokines in the peritoneal fluid—often without visible signs on standard imaging.

Diagnosis: The Role of Endometriosis Mapping

For patients with chronic pelvic pain, painful intercourse, or subtle cyclic symptoms, even when conventional imaging appears normal, advanced endometriosis mapping is recommended. This includes:

Specialized transvaginal ultrasound, with bowel preparation

Pelvic MRI with endometriosis protocol, using vaginal and rectal gel, antispasmodics, and a fasting regimen

These tools can identify deep lesions or posterior compartment involvement and help determine whether surgical intervention is warranted.

When Is Laparoscopy Indicated?

If symptoms persist and imaging remains inconclusive, diagnostic laparoscopy is often necessary—and offers the opportunity for simultaneous therapeutic intervention.

At EndoGlobalGroup, we emphasize:

✅ NO ablation of lesions, as this approach is incomplete and associated with high recurrence rates.

✅ We perform complete excision of all visible and suspected lesions, using microsurgical techniques that preserve fertility and restore normal pelvic anatomy.

Treatment Options Based on Age and Ovarian Reserve

Following diagnosis—or surgical excision when appropriate—treatment plans should be tailored individually:

Women under 35 with normal ovarian reserve:

Consider timed intercourse or intrauterine insemination (IUI) for up to 3–6 cycles.

Studies show improved outcomes post-laparoscopy with complete excision.

Women 35 and older, or with low ovarian reserve:

In vitro fertilization (IVF) is recommended to optimize success rates and reduce delays.

IVF bypasses the peritoneal environment and potential tubal dysfunction.

Comprehensive Care

Optimal care involves more than just medical or surgical treatment. At EndoGlobalGroup, we also provide:

Anti-inflammatory nutritional guidance and antioxidant support

Emotional and psychological support, especially for patients navigating long-standing unexplained infertility

A multidisciplinary team approach, including gynecologists, radiologists, fertility specialists, and expert surgeons
