Polycystic Ovary Syndrome (PCOS) What You Need to Know

What Is Polycystic Ovary Syndrome?

Polycystic Ovary Syndrome (PCOS) is one of the most common hormonal disorders affecting female fertility. It is associated with ovulation disorders (oligo-ovulation or anovulation), irregular menstrual cycles, weight gain, and difficulty conceiving. Many women searching for natural ways to manage PCOS or wondering how to get pregnant with polycystic ovaries often encounter conflicting information. At FertUlity, we follow a personalized approach that combines advanced diagnostics, nutritional interventions, and specialized IVF protocols for women with PCOS.

PCOS is a multifactorial endocrine disorder of the ovaries that disrupts normal ovulation. It is characterized by oligo-ovulation or anovulation, elevated androgen levels, and the presence of multiple small follicles in the ovaries. Beyond fertility, PCOS can also affect metabolic health, as it is often associated with insulin resistance, weight gain, and an increased risk of developing type 2 diabetes. It is estimated that around 1 in 10 women of reproductive age are affected by PCOS, with many cases remaining undiagnosed. Early diagnosis and individualized treatment are essential for improving fertility outcomes and overall health.

Symptoms & Clinical Signs of Polycystic Ovary Syndrome

Symptoms of polycystic ovary syndrome (PCOS) vary from woman to woman and may appear at different levels of intensity. Often, they go unnoticed for a long time, especially in adolescents or young women just starting menstruation. Recognizing the clinical signs is crucial for timely diagnosis and effective treatment of the syndrome.

Most common PCOS symptoms:

Irregular or absent menstrual cycles (oligomenorrhea or amenorrhea)
Difficulty conceiving due to irregular ovulation timing or absence of ovulation (anovulation)
Excess hair growth in areas such as the face, chest, abdomen, or back (hirsutism)
Acne, particularly in areas with increased oil production
Tendency for weight gain or difficulty losing weight
Hair thinning or hair loss with a male-pattern distribution
Darkened skin patches, usually on the neck, underarms, or groin (acanthosis nigricans)
Elevated androgen levels detected in laboratory tests

Clinical Findings Identified Through Diagnostic Tests

Elevated androgen levels in blood tests
Multiple immature ovarian follicles detected through ultrasound imaging
Insulin resistance
Elevated LH (luteinizing hormone) levels
Dyslipidemia (high triglycerides and low HDL cholesterol)
Elevated AMH (Anti-Müllerian Hormone) levels
Women who experience persistent symptoms should consult a specialized gynecologist or fertility specialist in order to undergo appropriate diagnostic evaluation and receive individualized treatment.

Causes & Risk Factors

Polycystic ovary syndrome does not have a single known cause but is believed to result from a combination of genetic, hormonal, and environmental factors. Understanding risk factors helps in targeted prevention and better condition management.

Possible causes and risk factors:

Heredity

Women with a family history of PCOS have increased chances of developing the syndrome.

Insulin resistance

Reduced cellular sensitivity to insulin leads to hyperinsulinemia, which may stimulate the overproduction of androgens by the ovaries.

Hormonal imbalance

Elevated LH (luteinizing hormone) or androgens contribute to ovulatory dysfunction.

Obesity

Increased fat mass worsens insulin resistance and negatively affects hormonal balance.

Low-grade inflammation

Systemic inflammation appears to play a role in PCOS pathogenesis.
Obesity and unhealthy dietary habits are aggravating factors that worsen PCOS
symptoms.

Diagnosing PCOS at FertUlity

The diagnosis of Polycystic Ovary Syndrome (PCOS) is based on the Rotterdam criteria, which suggest the diagnosis when two out of the following three criteria are present, after excluding other endocrine disorders:
Infrequent or absent ovulation (menstrual cycle irregularities)
Hyperandrogenism, either clinical (acne, hirsutism) or biochemical (elevated androgen levels)
Polycystic ovarian morphology detected on ultrasound
At FertUlity, we follow a comprehensive diagnostic approach that includes:
High-resolution gynecological ultrasound for detailed visualization of the ovaries
Hormonal blood testing, including FSH, LH, E2, PRL, Δ4 Androstenedione, 17-OH Progesterone, SHBG, free Testosterone, total Testosterone, DHEA-S, TSH, and AMH
Assessment of insulin resistance using HOMA-IR, HbA1c, or an oral glucose tolerance test
Early and accurate diagnosis is the first step toward optimizing fertility outcomes and preventing long-term health complications.

PCOS & Infertility

Polycystic Ovary Syndrome (PCOS) is one of the most common causes of oligo-ovulation or anovulation, meaning irregular or absent ovulation, and is therefore closely associated with infertility. In women with PCOS, the ovaries often contain multiple small follicles that fail to develop sufficiently to trigger ovulation. Hormonal imbalance, particularly increased androgen production and an altered LH/FSH ratio, disrupts the normal process of follicular development and egg maturation.

Even when ovulation occurs, egg quality and the endometrial environment may not always be optimal for implantation, which can further reduce the chances of conception. In addition, many women with PCOS experience insulin resistance, which negatively affects ovarian function as well as overall metabolic health.

How PCOS Affects Fertility

Irregular menstrual cycles: fewer opportunities for natural conception due to difficulty identifying fertile days

Anovulation: absence of ovulation and therefore no fertile window

Hormonal imbalance: affects proper egg maturation

Possible endometrial receptivity issues: implantation difficulties

Assisted Reproduction & PCOS

In vitro fertilization (IVF) is often the most effective option for women with PCOS who have not conceived naturally or through less complex fertility treatments. However, careful treatment planning is required due to the increased risk of ovarian hyperstimulation syndrome (OHSS).

At FertUlity, we implement personalized ovarian stimulation protocols, tailored to each woman's hormonal and metabolic profile.

IVF Success Rates in Women with PCOS

Success rates depend on several factors, including age, body mass index (BMI), egg quality, and the presence of additional infertility factors. In general:
Women under 35 with good ovarian response: success rates can reach 50–70% per IVF cycle
PCOS combined with obesity: weight loss before treatment may increase success rates by 15–20%
Our expertise in PCOS-related infertility allows us to design treatment plans that respect each woman’s physiology, minimize side effects, and maximize the chances of pregnancy with safety and support at every stage.

Therapeutic Approaches for Polycystic Ovary Syndrome

The management of Polycystic Ovary Syndrome (PCOS) requires a holistic and individualized approach, as symptoms and treatment goals vary from woman to woman. At FertUlity, we design treatment plans that combine medical therapy, lifestyle modifications, and specialized assisted reproduction techniques when necessary.

Medical Treatment

Medical treatment aims to restore hormonal balance, regulate ovulation, and address metabolic disturbances.

Oral contraceptive pills

Help regulate menstrual cycles, protect the endometrium from hyperplasia and polyp formation, and reduce androgen levels, improving acne and excessive hair growth.

Metformin

Improves insulin sensitivity and may support weight loss. In some cases, it can also help restore ovulation.

Letrozole or Clomiphene Citrate

Used to induce ovulation in women who wish to conceive naturally, often combined with ovulation monitoring and timed intercourse or as part of intrauterine insemination (IUI) treatment.

Anti-androgen medications

Used to reduce symptoms of hyperandrogenism, particularly when other treatments have not been effective and pregnancy is not an immediate goal.
The choice of treatment depends on each woman’s goals, whether the focus is cycle regulation, symptom management, or improving fertility.

Lifestyle Modifications

Lifestyle changes play a key role in managing PCOS, particularly in women with obesity or metabolic syndrome.

Balanced diet

A Mediterranean-style diet with a low glycemic index has been shown to help regulate insulin levels.

Regular physical activity

Aerobic exercise and interval training can improve insulin resistance and support menstrual cycle regulation.

Stress management

Relaxation techniques such as yoga or meditation may reduce inflammation and support overall hormonal balance.
At FertUlity, our approach combines nutritional guidance from specialists with ongoing monitoring and personalized support.

IVF for Women with PCOS

When medical treatment and lifestyle changes are not sufficient to achieve pregnancy, in vitro fertilization (IVF) can be a highly effective option. However, because women with PCOS have an increased risk of ovarian hyperstimulation syndrome (OHSS), treatment requires careful and specialized management.

Low-dose gonadotropin stimulation

Individualized stimulation protocols designed to minimize the risk of ovarian hyperstimulation.

Close monitoring with ultrasound and hormone levels

Frequent monitoring ensures safe and controlled ovarian stimulation.

Use of GnRH agonists

Used to trigger final egg maturation before egg retrieval, helping reduce the risk of OHSS.

Embryo freezing (freeze-all strategy)

When a high number of eggs are retrieved and the risk of OHSS is increased, delaying embryo transfer may improve safety and implantation outcomes.
Our team has extensive experience managing PCOS-related infertility with IVF, focusing on patient safety and optimal treatment outcomes.

PCOS & Pregnancy: What to Expect

Risks and Prevention of Pregnancy Complications

The presence of PCOS is associated with certain increased risks during pregnancy. However, these risks can be minimized with appropriate medical care and monitoring.

Gestational Diabetes (GDM)

Due to insulin resistance, women with PCOS have a higher risk of developing gestational diabetes. Regular glucose monitoring and a balanced diet are essential.

Pregnancy Hypertension / Preeclampsia

Hormonal and vascular imbalances may contribute to increased blood pressure during pregnancy.

Preterm Birth or Higher Likelihood of Cesarean Delivery

Although not inevitable, these outcomes occur more frequently in women with PCOS.

Luteal Phase Insufficiency

In some cases, progesterone support may be required to support implantation and reduce the risk of miscarriage or bleeding during the first trimester.

Multiple Pregnancies

When ovulation induction treatments are used, more than one egg may be released and fertilized, leading to multiple pregnancies. For this reason, careful medication dosing and close cycle monitoring are recommended.

Tips for a Healthy Pregnancy with PCOS

Undergo preconception evaluation to regulate hormonal and metabolic parameters before conception
Follow a low glycemic index diet and maintain regular physical activity, unless otherwise advised by your doctor
Monitor blood glucose and blood pressure regularly
Contact your gynecologist immediately in case of vaginal bleeding or abdominal pain
Pregnancy with PCOS can be completely normal when supported by early diagnosis, proper preparation, and close medical supervision. At FertUlity, we support you at every step of your journey, from conception to childbirth.

Frequently Asked Questions About Polycystic Ovary Syndrome (PCOS)

Can I have regular periods and still have PCOS?

Yes, it’s possible. Although irregular periods are a common symptom, some women with PCOS have relatively regular cycles but show other characteristics like hyperandrogenism or polycystic ovarian morphology on ultrasound.

Can PCOS go away after pregnancy?

Pregnancy may temporarily regulate cycles and hormones, but PCOS does not “disappear.” It is a chronic condition requiring ongoing monitoring, even after childbirth.

Does PCOS affect mental health?

Yes, PCOS has been linked to higher rates of anxiety, depression, and reduced self-esteem, particularly due to symptoms like acne, hirsutism, or infertility. Psychological support is a key part of comprehensive management.

How often should I be monitored if I have PCOS but am not trying to conceive?

Even without reproductive goals, annual checkups with a gynecologist and endocrinologist are recommended, including cycle evaluation, ultrasound, and basic blood tests.

Is there a natural treatment for PCOS without medication?

Lifestyle changes such as healthy nutrition and regular exercise can significantly improve PCOS symptoms and help restore ovulation in many women.

Can a teenager have PCOS?

Yes, PCOS can appear in adolescence, often as irregular periods, acne, and excess hair growth. Diagnosis is more challenging during puberty, as symptoms may overlap with normal age-related changes.

What tests are needed to diagnose PCOS?

The basic diagnostic tests include ovarian ultrasound, hormonal blood tests (FSH, LH, E2, PRL, Δ4 Androstenedione, 17-OH Progesterone, SHBG, free Testosterone, total Testosterone, DHEA-S, TSH, AMH), and evaluation of insulin resistance. In many cases, an oral glucose tolerance test or HOMA-IR assessment is also required.

Are there long-term health risks associated with PCOS?

Yes. If left untreated, PCOS may increase the risk of endometrial polyps, endometrial hyperplasia, and even endometrial cancer. Early diagnosis also allows the identification of other conditions that often coexist with PCOS, such as type 2 diabetes, hypertension, and dyslipidemia. Detecting these conditions early enables timely and targeted management, significantly reducing the risk of long-term complications.
