What is Endometriosis?
💡 Endometriosis = endometrial-like tissue growing outside the uterus. Found in 30–50% of infertile women. Symptoms: dysmenorrhoea, deep dyspareunia, pelvic pain, subfertility. Staging: I–IV (minimal to severe). Fertility impact: tubal distortion, adhesions, endometrioma (chocolate cyst), toxic peritoneal environment. Treatment: surgical (laparoscopy) + IVF if advanced or failed surgery.
Endometriosis is a chronic inflammatory condition in which endometrial-like tissue (similar to the uterine lining) grows outside the uterus — on the ovaries, fallopian tubes, peritoneum, and other pelvic structures. It affects approximately 10% of women of reproductive age and is found in 30–50% of women with infertility. Endometriosis impairs fertility through multiple mechanisms and requires staged, specialist management.
🇮🇳 India Context: Endometriosis is widely assessed and treated across major Indian fertility centres including Chennai, Mumbai, Bangalore, Delhi, and Hyderabad.
What are the key characteristics of Endometriosis?
- ASRM staging (I–IV): Stage I/II (minimal/mild) — small implants, no adhesions; Stage III/IV (moderate/severe) — endometriomas, dense adhesions, obliterated pouch of Douglas
- Endometrioma: ovarian endometriotic cyst ("chocolate cyst") — blood-filled cyst from cyclical bleeding of endometriotic tissue; reduces ovarian reserve by destroying surrounding follicles; bilateral endometriomas severely compromise AFC and AMH
- Fertility mechanisms: tubal distortion from adhesions; impaired folliculogenesis; toxic peritoneal fluid (cytokines, free radicals) impairing sperm and egg function; altered uterine receptivity; endometriomas reducing reserve
- Diagnosis: clinical suspicion (symptoms + TVS endometrioma) → laparoscopy with histological confirmation (gold standard); CA-125 non-specific; deep infiltrating endometriosis (DIE) requires MRI
- Surgical treatment (laparoscopy): excision (not ablation) of endometriomas and implants; improves natural pregnancy rates in mild-moderate disease; Stage I/II surgery doubles spontaneous pregnancy rate; Stage III/IV surgery + IVF often needed
- Endometrioma and IVF: surgery before IVF for endometrioma >4cm is debated — reduces ovarian reserve further; most guidelines recommend surgery if symptomatic, bilateral, or >4cm; smaller cysts can be left and IVF performed
- Recurrence: endometriosis recurs after surgery in 20–50% at 5 years; GnRH agonist or progestins post-surgery reduce recurrence but delay fertility
- Deep infiltrating endometriosis (DIE): bowel, bladder, ureteric involvement; requires specialist multidisciplinary surgery; significant impact on IVF outcomes
How does Endometriosis work?
Why does Endometriosis matter in fertility?
Endometriosis is the most complex fertility condition to manage — it is progressive, recurrent, and damages ovarian reserve with each endometrioma and each surgical intervention. The critical clinical balance: operating on endometriomas reduces acute toxicity but each surgery removes healthy ovarian cortex along with the cyst lining, permanently reducing reserve. For women with endometriosis and infertility, the most time-sensitive intervention is egg freezing or IVF before reserve is further compromised by disease progression or repeat surgery.

FAQs about Endometriosis
Can I get pregnant with endometriosis?
Yes, many women with endometriosis conceive — naturally or with treatment. Mild cases may not significantly affect fertility. Moderate to severe cases may benefit from surgery to remove implants, followed by IUI or IVF if needed.
How does endometriosis affect fertility?
Endometriosis can impair fertility by damaging eggs, blocking fallopian tubes, creating adhesions, producing inflammatory substances that harm embryos, and affecting the uterine lining for implantation.
Is IVF effective for endometriosis?
Yes. IVF success rates for women with endometriosis are 30–45% per cycle, depending on severity. IVF bypasses the tubes and places the embryo directly in the uterus, overcoming many endometriosis-related barriers.
How is endometriosis diagnosed?
Definitive diagnosis requires laparoscopy (keyhole surgery). Ultrasound and MRI can detect endometriomas (chocolate cysts) but may miss superficial implants. Symptoms include painful periods, pain during intercourse, and chronic pelvic pain.
Does endometriosis surgery improve fertility?
Yes, surgical removal of endometrial implants can improve natural conception rates by 40–60% in the 6–12 months following surgery. Your doctor may recommend trying naturally for 6 months post-surgery before considering IVF.
