Endometriosis: Surgery or IVF First?

If you’ve been diagnosed with endometriosis, you’ve probably heard that endometriosis surgery can affect your ability to have children. We clearly know that up to half of women with endometriosis may face fertility challenges at some point.

This isn’t always the case—many women conceive naturally—but endometriosis surgery also can damage the ovaries, reduce the number of eggs. The good news? Fertility preservation gives you the option to plan ahead and keep the door open for future pregnancy.

How Endometriosis Surgery Affects Fertility

Endometriosis is when tissue similar to the lining of the uterus grows outside it—often on the ovaries, tubes, or pelvic walls. Here’s how it can interfere with fertility:

• Ovarian damage: Cysts called endometriomas can form on the ovaries. Inside, there’s fluid packed with inflammatory chemicals that harm healthy ovarian tissue and reduce egg supply.
• Fibrotic tissue & adhesions: Endometriosis surgery and disease itself can distort pelvic anatomy, making it harder for the egg to travel down the fallopian tube.
• Inflammation: The disease can create a hostile pelvic environment that affects egg quality, sperm movement, and embryo implantation.
• Surgical side effects: While surgery can remove disease and improve anatomy, it can also unintentionally remove healthy ovarian tissue—especially with repeat procedures.

Your Options for Fertility Preservation

Thanks to advances in reproductive medicine, women with endometriosis now have several ways to preserve fertility:

1. Egg Freezing (Oocyte Cryopreservation)

• The most recommended option for young women.
• Does not damage ovarian reserve.
• No partner is required.
• Works best when done before age 35 or before significant ovarian damage occurs.

2. Embryo Freezing

• Highly effective if you have a partner or want to use donor sperm.
• Creates embryos now for use in the future.

3. Ovarian Tissue Freezing

• Involves removing and freezing part of the ovary.
• Mostly used in cancer patients, but it may be an option if ovary removal is necessary during surgery.

When Should You Think About Preserving Fertility?

Doctors may suggest it if you have:

• Bilateral endometriomas (on both ovaries).
• Recurrent endometriomas after surgery.
• Low ovarian reserve (low AMH or low antral follicle count).
• A history or high risk of multiple surgeries.
• Large ovarian cysts (>4 cm).
• Advanced endometriosis (stage III–IV).
• Age over 35 and not ready to get pregnant yet.

Surgery or IVF First?

The choice depends on your situation:

• Surgery first: If you have significant pain, distorted pelvic anatomy, or symptoms that affect quality of life.
• IVF first: If your main goal is pregnancy and you have low ovarian reserve, are older, or have deep infiltrating endometriosis where surgery could harm ovarian function.
• Egg freezing before surgery: Protects your egg supply from potential surgical damage.

“While general strategies can guide IVF decisions, management in endometriosis should always be personalized—planned together by surgeons and fertility specialists, not applied the same way to every patient.”

How Many Eggs Is a Good Count?

Studies suggest that at least 10 mature eggs give a good chance of one live birth in the future.

• Women with endometriosis sometimes need more than one stimulation cycle to reach this number.
• The younger you are when you freeze eggs, the better the results.

Endometriosis doesn’t mean you can’t have children—but it does mean thinking ahead is important. Fertility preservation, especially egg freezing, can give you peace of mind and more options later.

If you’re living with endometriosis and wondering about your fertility, talk to a fertility specialist as soon as possible. The earlier you explore your options, the more choices you’ll have for building your family—on your own timeline.
