Endometriosis is a condition in which tissue similar to the lining of the uterus grows outside the uterus. It may involve the ovaries, fallopian tubes, pelvic lining, or surrounding reproductive structures.

Some patients with endometriosis conceive naturally, while others may experience difficulty becoming pregnant and eventually consider in vitro fertilization (IVF).

IVF can be an important treatment option because it allows eggs to be retrieved directly from the ovaries, fertilized in the laboratory, and transferred into the uterus without relying on normal fallopian-tube function.

However, there is no single IVF strategy that is appropriate for every patient with endometriosis. Treatment may need to be individualized according to age, ovarian reserve, the presence of endometriomas, previous surgery, pelvic anatomy, embryo development, uterine factors, pain symptoms, and previous fertility treatment.

Why Endometriosis May Affect IVF Treatment

Endometriosis may influence IVF treatment in several different ways.

‍

Ovarian Reserve

When endometriosis affects the ovaries, particularly when ovarian endometriomas are present, ovarian reserve may be reduced in some patients.

Previous ovarian surgery can also be relevant because removal of an endometrioma may sometimes affect healthy ovarian tissue as well as the cyst.

This can influence:

• The number of follicles available for stimulation
• The number of eggs retrieved
• Medication planning
• Decisions about whether to pursue embryo banking
• The timing of treatment

‍

Ovarian Response to Stimulation

Some patients with endometriosis respond well to ovarian-stimulation medications, while others may develop fewer follicles than expected.

The fertility specialist may adjust the IVF protocol according to ovarian reserve, previous response, age, and treatment goals.

‍

Pelvic Anatomy

Endometriosis may cause adhesions or changes in pelvic anatomy that can affect the ovaries or fallopian tubes.

While IVF bypasses the fallopian tubes for fertilization, pelvic anatomy may still be relevant for egg retrieval or other aspects of treatment.

‍

Uterine and Endometrial Environment

Endometriosis may also be associated with changes in the pelvic or uterine environment that can be considered during embryo-transfer planning.

This does not mean that every patient with endometriosis has an implantation problem. Embryo quality, chromosome status, uterine anatomy, hormonal preparation, and many other factors also influence implantation.

‍

‍

How Endometriosis Is Commonly Evaluated Before IVF

Before beginning IVF, the fertility specialist may review several areas.

Ovarian Reserve

Testing may include:

• AMH
• Antral follicle count
• FSH
• Estradiol

These tests help estimate how the ovaries may respond to stimulation.

They do not directly measure egg quality or guarantee how many embryos will develop.

‍

Pelvic Ultrasound

Ultrasound may help identify:

• Ovarian endometriomas
• Fibroids
• Adenomyosis
• Other ovarian or uterine findings

‍

Tubal and Uterine Evaluation

Depending on the patient's history, additional evaluation may be performed for:

• Hydrosalpinx
• Uterine polyps
• Fibroids
• Uterine cavity abnormalities
• Other structural factors

‍

Previous Fertility Treatment

If IVF has already been attempted, the fertility team may review:

• Medication doses
• Follicular response
• Number of eggs retrieved
• Egg maturity
• Fertilization
• Blastocyst development
• Embryo quality
• Transfer protocol
• Pregnancy outcomes

This information can help guide the next treatment strategy.

‍

‍

IVF Treatment Options for Patients with Endometriosis

This is often the most important part of treatment planning.

There may be several possible approaches, and the appropriate choice depends on the individual patient.

‍

Proceeding Directly to IVF

For some patients, moving directly to IVF may be reasonable rather than attempting additional surgery or multiple IUI cycles.

This may be considered when:

• Age makes reproductive timing important
• Ovarian reserve is reduced
• Fallopian-tube function is impaired
• Endometriosis is more advanced
• Previous IUI treatment has been unsuccessful
• Male-factor infertility is also present
• Previous surgery has already been performed

The goal may be to avoid delaying egg retrieval when ovarian reserve or reproductive age is a concern.

Ovarian Stimulation Protocol Selection

There is no single ovarian-stimulation protocol used for every patient with endometriosis.

The fertility specialist may individualize treatment based on:

• Age
• AMH
• Antral follicle count
• Previous ovarian response
• Endometrioma history
• Previous surgery
• Number of desired embryos

Medication doses may be adjusted throughout stimulation according to ultrasound and hormone monitoring.

The purpose is to recruit an appropriate group of follicles while maintaining treatment safety.

‍

IVF With an Ovarian Endometrioma

An endometrioma does not automatically need to be removed before IVF.

The decision may depend on:

• Size
• Location
• Pain
• Ultrasound appearance
• Accessibility of follicles during egg retrieval
• Previous surgery
• Ovarian reserve
• Concern for other ovarian pathology

In some cases, IVF may proceed with an endometrioma in place.

In other cases, surgery may be considered before IVF if there is significant pain, diagnostic uncertainty, technical difficulty with retrieval, or another medical reason.

‍

Surgery Before IVF

Surgery can sometimes improve pelvic anatomy or relieve symptoms, but surgery involving the ovaries may also reduce ovarian reserve.

For this reason, surgery before IVF should be individualized.

Potential reasons surgery may be considered include:

• Severe pelvic pain
• Large symptomatic endometrioma
• Suspicious ovarian findings
• Difficult access to follicles for egg retrieval
• Significant pelvic anatomy concerns
• Other gynecologic indications

When ovarian reserve is already low, the potential reproductive impact of additional ovarian surgery should be carefully discussed.

‍

IVF Before Surgery

In selected patients, fertility preservation or embryo creation may be considered before additional ovarian surgery.

This may be relevant when:

• Ovarian reserve is low
• Both ovaries are affected
• Previous ovarian surgery has already occurred
• Additional surgery could affect ovarian tissue
• Reproductive age is advancing

In these situations, the fertility team may discuss egg or embryo freezing before surgery.

‍

Embryo Banking

Some patients may undergo more than one egg retrieval before embryo transfer.

This approach is sometimes referred to as embryo banking.

It may be considered when:

• Ovarian reserve is reduced
• Egg yield per retrieval is low
• Multiple embryos are desired for future family planning
• Surgery or another treatment is planned before transfer
• Age makes embryo accumulation a consideration

Embryo banking is not necessary for every patient and should be individualized based on goals, cost, ovarian response, and expected benefit.

‍

Fresh Versus Frozen Embryo Transfer

Patients with endometriosis may undergo either fresh or frozen embryo transfer depending on the IVF protocol and clinical circumstances.

A fresh transfer occurs within the same cycle as egg retrieval.

A frozen embryo transfer (FET) occurs in a later cycle after embryos have been frozen.

A frozen transfer may allow:

• Recovery after ovarian stimulation
• Separate preparation of the uterine lining
• Additional treatment before transfer when clinically indicated
• Greater flexibility in transfer timing

The fertility specialist determines which approach is appropriate.

‍

Medical Suppression Before Embryo Transfer

In selected patients, particularly when endometriosis or adenomyosis is considered clinically important, the fertility specialist may discuss a period of hormonal suppression before frozen embryo transfer.

Medications may temporarily reduce ovarian hormonal activity and suppress endometriosis-related activity before the transfer cycle begins.

This is not necessary for every patient with endometriosis, and the potential benefits, treatment delay, side effects, and individual fertility history should be considered.

‍

Natural-Cycle Frozen Embryo Transfer

Patients who ovulate regularly may sometimes use a natural or modified-natural frozen embryo transfer cycle.

In this approach, embryo-transfer timing is coordinated with the patient's own ovulation.

The fertility clinic may monitor:

• Follicular development
• Hormone levels
• Ovulation
• Endometrial development

A trigger injection or progesterone may also be used depending on the protocol.

‍

Medicated Frozen Embryo Transfer

In a medicated cycle, estrogen and progesterone are used to prepare the uterine lining and control embryo-transfer timing.

This can provide greater scheduling control and may be appropriate for patients with irregular cycles or other clinical considerations.

The choice between natural and medicated transfer depends on the patient's history and fertility-clinic protocol.

How Acupuncture May Support IVF Care with Endometriosis

Acupuncture may be incorporated as complementary care before and during IVF.

Supporting Ovarian and Pelvic Circulation

Acupuncture may be used with the goal of supporting ovarian and pelvic circulation.

This may be relevant before and during ovarian stimulation as follicles develop.

Adequate circulation helps deliver oxygen, hormones, and nutrients to reproductive tissues.

‍

Supporting the Follicular Environment

Follicular development is influenced by age, ovarian reserve, hormones, circulation, metabolic health, and other biological factors.

Acupuncture may be used to support:

• Ovarian circulation
• The physiological environment surrounding developing follicles
• Sleep
• General reproductive wellness
• Physical comfort during stimulation

‍

Supporting Uterine and Endometrial Health

When embryo transfer is planned, acupuncture may shift toward supportive care focused on:

• Uterine circulation
• Pelvic circulation
• The physiological environment of the endometrium
• Physical comfort
• Sleep
• Nervous-system regulation

‍

‍

When Endometriosis and IVF Options Should Be Discussed with a Fertility Specialist

A fertility specialist may help patients decide whether IVF, surgery, IUI, fertility preservation, or another approach is most appropriate.

Evaluation may be especially important when:

• Pregnancy has not occurred after an appropriate period of trying
• Reproductive age is becoming an important factor
• Ovarian reserve is reduced
• Endometriomas are present
• Previous ovarian surgery has occurred
• Additional ovarian surgery is being considered
• Fallopian-tube function is impaired
• Hydrosalpinx is present
• Previous IUI treatment has not worked
• Previous IVF resulted in a low egg yield
• Embryo development has been limited
• Previous embryo transfers have been unsuccessful
• Adenomyosis is also present
• Pelvic pain is significant
• Fertility preservation is being considered

The key question is not simply whether a patient has endometriosis, but which treatment strategy offers the most appropriate balance between reproductive timing, ovarian reserve, symptoms, and overall fertility goals.
