Polycystic Ovary Syndrome (PCOS) is one of the most common hormonal disorders affecting women of reproductive age. A question frequently asked by women diagnosed with PCOS is: Does PCOS cause infertility?
The short answer is PCOS can contribute to infertility, but it does not mean you cannot get pregnant. Many women with PCOS conceive naturally or with appropriate medical treatment. Understanding how PCOS affects ovulation, hormone balance, egg quality, and reproductive health can help women take proactive steps toward pregnancy.
In this comprehensive guide, we will discuss how PCOS impacts fertility, signs of infertility in PCOS, available treatment options, pregnancy success rates, lifestyle modifications, and expert recommendations.
What Is PCOS?
Polycystic Ovary Syndrome (PCOS) is a hormonal condition characterized by:
- Irregular or absent periods
- Excess androgen (male hormone) levels
- Multiple small follicles in the ovaries
- Insulin resistance
- Weight gain
- Acne and excessive hair growth
PCOS affects approximately 8-13% of women worldwide and is among the leading causes of ovulatory infertility.
According to the World Health Organization (WHO), infertility affects millions of people worldwide, and conditions such as PCOS are among the leading causes of ovulatory infertility in women. Learn more from the WHO infertility fact sheet.
Does PCOS Cause Infertility?
PCOS does not directly make every woman infertile.
Instead, it interferes with normal ovulation, making conception more difficult.
Infertility is defined as:
Women with PCOS often experience:
- Irregular ovulation
- Delayed ovulation
- Absent ovulation (anovulation)
Since ovulation is necessary for pregnancy, fertility may be reduced.
However, many women with PCOS successfully become pregnant after lifestyle modifications or fertility treatments.
How PCOS Affects Fertility
1. Irregular Ovulation
Healthy ovaries release one mature egg every month.
In PCOS:
- Follicles begin developing
- Eggs fail to mature completely
- Ovulation may not occur
Without ovulation, pregnancy cannot happen naturally.
Regular ovulation significantly improves the chances of natural conception in women with PCOS. Learn how to identify ovulation, recognize fertile days, and understand ovulation problems in PCOS to improve your chances of pregnancy.
2. Hormonal Imbalance
Women with PCOS commonly have elevated:
- Testosterone
- LH (Luteinizing Hormone)
- Insulin
These hormonal changes disrupt:
- Egg maturation
- Follicle development
- Ovulation timing
This significantly affects fertility.
Restoring hormonal balance can lead to more regular menstrual cycles and better reproductive health. Explore our detailed guide on PCOS treatment options and hormone management
3. Insulin Resistance
Nearly 70% of women with PCOS have insulin resistance.
High insulin levels:
- Increase androgen production
- Worsen ovulation problems
- Promote weight gain
Insulin resistance is considered a major contributor to fertility issues in PCOS.
For evidence-based guidance on PCOS diagnosis, symptoms, causes, and treatment, refer to the National Institute of Child Health and Human Development (NICHD) PCOS resource.
4. Poor Egg Quality
Not every woman with PCOS experiences poor egg quality.
However:
- Chronic hormonal imbalance
- Obesity
- Metabolic dysfunction
can negatively influence egg development.
5. Obesity and Fertility
Many women with PCOS struggle with weight gain.
Excess body weight can:
- Reduce ovulation frequency
- Increase miscarriage risk
- Lower IVF success rates
Even a modest weight loss of 5–10% may significantly improve fertility outcomes.
Can You Get Pregnant Naturally with PCOS?
Yes.
Many women with PCOS conceive naturally.
Natural pregnancy is more likely when:
- Ovulation occurs regularly
- Weight is healthy
- Insulin resistance is controlled
- Hormonal balance improves
Women with mild PCOS often achieve pregnancy without fertility treatment.
Signs That PCOS May Be Affecting Fertility
Common indicators include:
Irregular Periods
Cycles longer than 35 days suggest infrequent ovulation.
Irregular or delayed periods are often one of the earliest signs of PCOS. If your menstrual cycles are consistently longer than 35 days or unpredictable, learn more about the causes, diagnosis, and treatment of irregular periods.
Missing Periods
Absent periods often indicate anovulation.
Missing periods (amenorrhea) may occur when ovulation does not happen regularly. Read our detailed guide on why periods stop, common causes, and when to see a gynecologist.
Difficulty Conceiving
Trying for over a year without success may warrant evaluation.
Women with PCOS may have difficulty conceiving because irregular ovulation reduces the chances of pregnancy. Learn how PCOS affects fertility and the treatment options available.
Elevated Male Hormones
Symptoms include:
- Facial hair
- Acne
- Scalp hair thinning
High androgen levels can cause acne, excessive facial hair, and scalp hair thinning. Learn more about hyperandrogenism in PCOS and available treatment options.
Weight Gain
Particularly around the abdomen.
Weight gain and insulin resistance often reinforce each other in PCOS, making symptoms more difficult to control. Read our guide on healthy weight management strategies for women with PCOS.
Women experiencing irregular cycles, acne, or excess hair growth should also read our detailed guide on PCOS vs PCOD: What Is the Difference? This article explains hormonal changes, symptoms, diagnosis, and fertility implications, helping women understand whether their symptoms are affecting ovulation and reproductive health.
Why Women with PCOS Have Difficulty Ovulating
Ovulation requires a coordinated interaction between:
- Brain
- Pituitary gland
- Ovaries
PCOS disrupts this communication.
Common findings include:
- Elevated LH levels
- Increased androgens
- Follicular arrest
As a result:
- Eggs remain trapped in follicles
- Ovulation does not occur
This is why infertility is common in untreated PCOS.
Is PCOS the Most Common Cause of Female Infertility?
Yes.
PCOS is the leading cause of:
It accounts for approximately:
- 70–80% of anovulatory infertility cases
However, infertility can also result from:
- Endometriosis
- Tubal blockage
- Male factor infertility
- Age-related decline
Therefore, a complete fertility evaluation is essential.

Fertility Testing in Women with PCOS
Your gynecologist may recommend:
Blood Tests
Including:
- LH
- FSH
- Testosterone
- AMH
- Insulin
- Thyroid profile
Pelvic Ultrasound
Evaluates:
- Ovarian appearance
- Follicle count
Ovulation Assessment
Tracks whether ovulation occurs.
Semen Analysis
Male fertility should also be evaluated.
Tubal Patency Tests
Such as HSG (Hysterosalpingography).
Can PCOS Cause Permanent Infertility?
No.
PCOS generally causes:
Subfertility rather than permanent infertility.
Many women become pregnant through:
- Lifestyle modifications
- Ovulation induction
- Fertility treatment
The ovaries still contain eggs; the primary issue is ovulation dysfunction.
Best Treatments for PCOS-Related Infertility
Lifestyle Changes
First-line treatment includes:
- Weight reduction
- Exercise
