Can IVF Work With One Ovary? Success & Treatment Options

Yes, IVF can work with one ovary. Having only one ovary does not automatically mean that IVF or pregnancy is impossible. The remaining ovary can continue producing eggs, although women with one ovary may sometimes produce fewer eggs during IVF stimulation than women with two ovaries.

IVF success with one ovary depends on several factors, especially age, ovarian reserve, AMH, egg quality, sperm quality, embryo development and overall reproductive health. Studies have found that women with one ovary may have lower egg numbers after stimulation, while pregnancy and live-birth outcomes can still be possible.

Can You Have IVF With One Ovary?

Yes. If one ovary has been surgically removed or is no longer functioning, the remaining ovary can still respond to fertility medicines and produce eggs for IVF.

During IVF, doctors use ovarian stimulation medicines to encourage the available follicles to develop. The response is monitored using ultrasound and, when appropriate, hormone testing. Current ESHRE guidance emphasizes individualized ovarian stimulation based on the patient's expected ovarian response and clinical circumstances.

Having one ovary therefore does not automatically rule out IVF.

Why Does Having One Ovary Affect IVF?

The main difference is the number of eggs that may be available for stimulation.

Women with one ovary may:

• Produce fewer follicles during stimulation.
• Have fewer eggs retrieved.
• Sometimes require individualized stimulation planning.
• Have fewer embryos available for selection.

A meta-analysis of IVF/ICSI studies found that women with previous unilateral oophorectomy generally had fewer retrieved oocytes and required higher gonadotropin doses than women with two ovaries.

However, having fewer eggs does not necessarily mean that pregnancy cannot occur.

Can the Remaining Ovary Compensate?

The remaining ovary can continue functioning and may show compensatory follicular recruitment.

One study comparing women with one ovary with women who had two ovaries found that the remaining ovary could produce a relatively strong follicular response when compared with an individual ovary in women with two ovaries. Live-birth rates in that study were similar between groups.

This helps explain why one ovary can be sufficient for IVF and pregnancy in many women.

What Is IVF Success With One Ovary?

There is no single IVF success rate for women with one ovary.

Outcomes vary depending on:

• Age
• AMH level
• Antral Follicle Count (AFC)
• Egg quality
• Sperm quality
• Embryo quality
• Uterine health
• Cause of infertility
• Previous IVF response

Research is somewhat mixed. A 2018 meta-analysis found comparable clinical pregnancy odds between women with one ovary and women with two ovaries, while a later 2022 meta-analysis found lower pregnancy and live-birth odds after unilateral oophorectomy. The studies were observational and had important differences and limitations, so individual counseling is more useful than relying on a single percentage.

Does One Ovary Mean Low AMH?

Not necessarily.

AMH reflects ovarian reserve and can help predict how many eggs may be retrieved during IVF, but it does not by itself determine whether pregnancy is possible.

ASRM notes that AMH and AFC are useful predictors of ovarian response, while age is a stronger predictor of reproductive success than ovarian reserve markers alone.

Therefore, a woman with one ovary should not judge her IVF chances based on AMH alone.

What Tests Are Done Before IVF With One Ovary?

A fertility specialist will usually evaluate both the remaining ovary and the overall reproductive health of the couple.

Ovarian Reserve Testing

Depending on the situation, this may include:

• AMH
• Antral Follicle Count
• Ultrasound
• Other hormone tests when indicated

AMH and AFC are among the most useful tests for predicting ovarian response to IVF stimulation.

Medical History

The doctor may want to know:

• Why the ovary was removed
• When the surgery was performed
• Previous ovarian surgery
• Endometriosis history
• Previous pregnancies
• Previous IVF or IUI treatment
• Any other reproductive conditions

Male Fertility Testing

The male partner should also be evaluated, usually beginning with:

• Semen Analysis
• Sperm Count
• Sperm Motility
• Sperm Morphology

This is important because both partners can contribute to fertility problems.

How Does IVF Work With One Ovary?

The basic IVF process is similar to IVF with two ovaries.

Ovarian Stimulation

Fertility medicines are used to stimulate the remaining ovary and encourage follicular development.

Follicular Monitoring

Ultrasound monitoring helps the doctor assess follicle growth and decide when the follicles are ready for egg retrieval.

Egg Retrieval

When appropriate, the mature eggs are collected from the remaining ovary.

Fertilization

Eggs are fertilized with sperm in the laboratory. Depending on the case, conventional IVF or ICSI may be used.

Embryo Development

The resulting embryos are monitored in the laboratory.

Embryo Transfer

A suitable embryo may then be transferred into the uterus, either during the same treatment cycle or later as a frozen embryo transfer.

Can One Ovary Produce Enough Eggs for IVF?

Yes. One ovary can produce eggs for IVF, but the number varies considerably between patients.

Some women may have a good response, while others may have a lower ovarian response. This is why AMH, AFC, age and previous ovarian response are important when planning treatment.

The goal is not simply to obtain a large number of eggs. The objective is to obtain eggs that can potentially develop into viable embryos.

Does Age Matter More When You Have One Ovary?

Yes. Age remains an important factor in IVF outcomes.

Even with one ovary, a younger woman may have better reproductive potential than an older woman with two ovaries. This is because egg quality and chromosomal normality are strongly associated with age.

Ovarian reserve tests can help predict egg yield, but they cannot fully predict egg quality or reproductive success.

Can IVF Work With One Ovary and Low AMH?

Yes, it can.

Having both one ovary and low AMH may indicate a lower expected ovarian response, meaning fewer eggs may be retrieved. However, extremely low AMH should not automatically be considered a reason to refuse IVF treatment.

Your doctor may consider:

• Individualized stimulation
• Expected egg yield
• Age and egg quality
• Previous IVF response
• Embryo development
• Whether repeated retrievals are appropriate

What If Only a Few Eggs Are Retrieved?

A low number of eggs does not automatically mean that IVF will fail.

Even a small number of retrieved eggs can potentially result in a viable embryo. However, fewer eggs can mean fewer opportunities for fertilization and embryo development.

The doctor may review the response and determine whether the stimulation protocol should be adjusted in a future cycle.

Can Donor Eggs Be Used If IVF With One Ovary Does Not Work?

Yes. Donor-egg IVF may be an option in selected situations, particularly when ovarian reserve is severely reduced or repeated IVF cycles using the patient's own eggs have not produced suitable embryos.

However, this is not automatically necessary just because a woman has one ovary.

The decision depends on:

• Age
• Ovarian reserve
• Previous IVF outcomes
• Egg retrieval results
• Embryo development
• Individual reproductive goals

Is IVF Safe With One Ovary?

Having one ovary does not by itself make IVF unsafe. However, every IVF treatment carries potential risks, and the stimulation plan should be individualized.

The doctor will monitor ovarian response during stimulation and adjust treatment when needed. Modern IVF guidelines emphasize individualized stimulation and monitoring to balance effectiveness and safety.

What Can You Do Before IVF With One Ovary?

There is no proven diet or home remedy that can create additional ovarian tissue or restore a removed ovary.

However, general preconception health is important.

Before IVF

• Avoid smoking and tobacco.
• Avoid recreational drugs.
• Limit or avoid alcohol.
• Maintain a healthy weight.
• Eat a balanced diet.
• Get adequate sleep.
• Take folic acid or other supplements only as advised.
• Keep thyroid, diabetes and other medical conditions under control.

These measures support overall health but cannot guarantee IVF success.

Questions to Ask Your Doctor

If you have one ovary and are considering IVF, ask:

• What is my AMH level?
• What is my Antral Follicle Count?
• How many eggs might I expect from stimulation?
• Does my age affect my chances?
• What IVF protocol is appropriate for me?
• Should I consider IVF or IUI first?
• What is my estimated chance of obtaining a good-quality embryo?
• Should we consider embryo freezing?
• What happens if the first cycle produces very few eggs?
• When would donor eggs be considered?

Conclusion

Yes, IVF can work with one ovary. Having one ovary may reduce the number of eggs available during stimulation, but it does not mean that pregnancy or IVF is impossible. Research suggests that women with one ovary can still achieve pregnancy and live birth through IVF, although outcomes may differ from women with two ovaries.

The most important factors to consider are age, ovarian reserve, egg quality, sperm quality and embryo development. A personalized fertility assessment is therefore much more useful than judging IVF success based only on the number of ovaries.

Frequently Asked Questions (FAQs)

Can IVF work with one ovary?

Yes. One functioning ovary can produce eggs for IVF, although the number of eggs retrieved may be lower in some women.

Is IVF success lower with one ovary?

Some studies have found lower egg numbers and, in some analyses, lower pregnancy or live-birth rates after unilateral oophorectomy. However, individual outcomes vary significantly.

Can one ovary produce enough eggs for IVF?

Yes. The response varies from woman to woman. AMH, AFC, age and previous treatment response can help estimate the likely ovarian response.

Can I get pregnant naturally with one ovary?

Yes. One functioning ovary can release eggs and support natural ovulation. Fertility also depends on factors such as age, the remaining ovary, Fallopian Tube function and sperm quality.

Does having one ovary mean I need donor eggs?

No. Donor eggs are not automatically required. IVF using your own eggs may be possible depending on ovarian reserve, age and treatment response.
