Polycystic Ovary Syndrome (PCOS) is one of the most common hormonal and metabolic conditions affecting women of reproductive age. It can affect menstrual cycles, ovulation, fertility, metabolism, skin, hair, and psychological wellbeing. Although PCOS is a long-term condition, its symptoms and associated health risks can often be effectively managed with appropriate care, lifestyle measures, and medical treatment.
Many women may not recognise that irregular periods, acne, or changes in hair growth can be associated with PCOS. Understanding what PCOS is, its possible underlying factors, signs and symptoms, available diagnostic tests, and treatment options is an important first step towards managing reproductive and overall health.
PCOS is a hormonal condition associated with features such as irregular ovulation, increased androgen levels, and polycystic ovarian morphology. Increased androgen activity and disrupted ovulation can contribute to irregular menstrual cycles and difficulties with conception.
Despite its name, not every woman with PCOS has polycystic ovaries. The ovaries may contain multiple small follicles that have not developed fully, rather than true ovarian cysts.
PCOS affects women differently. Some experience relatively mild symptoms, while others may have more significant reproductive, metabolic, or psychological concerns.
PCOS can affect more than the ovaries and may influence several areas of health, including:
PCOS is also associated with an increased risk of metabolic conditions, including type 2 diabetes, high blood pressure, abnormal cholesterol levels, and sleep apnoea. Psychological symptoms, including anxiety and depression, are also common. Appropriate medical care, healthy lifestyle habits, and regular health assessments can help manage these risks.
The exact cause of PCOS is not fully understood. Research suggests that genetic, hormonal, metabolic, and environmental factors may contribute to its development.
Women with PCOS may have increased androgen activity, which can interfere with normal ovulation and contribute to symptoms such as excess facial or body hair and acne.
Insulin resistance is common in PCOS. When the body’s cells respond less effectively to insulin, the body may produce more insulin. Higher insulin levels can contribute to increased androgen production and may affect normal ovulation.
PCOS can run in families, suggesting that genetic factors may contribute to a woman’s likelihood of developing the condition.
PCOS involves complex interactions between hormonal and metabolic factors. Inflammation has also been studied in relation to PCOS, although it should not be considered a single established cause of the condition.
Symptoms can vary considerably between women. Common signs and symptoms include:
Some women experience several symptoms, while others may have only one or two.
Some women with PCOS have ovaries containing a higher number of small follicles visible on an ultrasound scan. However:
Doctors therefore consider a combination of symptoms, medical history, hormone levels, and, where appropriate, ultrasound or other investigations when assessing PCOS. In adults, anti-Müllerian hormone (AMH) may also be used as an alternative to ultrasound for assessing polycystic ovarian morphology in appropriate circumstances.
PCOS can present differently from one woman to another. Although some sources describe informal categories such as insulin-resistant, inflammatory, adrenal, or post-pill PCOS, these are not universally recognised clinical subtypes.
For this reason, treatment should be based on an individual’s symptoms, reproductive goals, metabolic health, and overall medical needs rather than assigning them to a specific PCOS type.
There is no single test that can diagnose PCOS in every patient. Healthcare professionals generally consider a combination of clinical history, symptoms, examination, laboratory tests, and, where appropriate, ultrasound findings.
Doctors may ask about:
Depending on the individual, healthcare professionals may assess:
Blood tests may be used to assess hormone levels, including androgens, and to help exclude other conditions that can cause similar symptoms. Additional metabolic testing may also be appropriate depending on the individual’s circumstances.
PCOS is a common cause of ovulatory difficulties, but many women with PCOS are able to become pregnant, either naturally or with appropriate fertility treatment.
Depending on individual circumstances, treatment options may include:
A personalised fertility assessment can help determine the most suitable approach for women who are experiencing difficulty conceiving. Evidence-based fertility management is an important component of PCOS care.
PCOS is not usually life-threatening, but it is associated with an increased risk of several long-term health concerns, including:
Regular medical assessment, appropriate lifestyle measures, and evidence-based treatment can help manage symptoms and reduce associated health risks.
There is currently no single cure for PCOS. However, symptoms and associated health risks can often be effectively managed.
Treatment may focus on:
Treatment should be individualised according to each woman’s symptoms, health needs, and fertility plans.
PCOS management requires an individualised treatment strategy, particularly for women who are planning pregnancy. Patients at NJINSKY IVF & Fertility Clinic undergo thorough evaluations to help diagnose PCOS and assess its potential impact on fertility and overall reproductive wellbeing.
The clinic offers services including hormonal testing, pelvic ultrasound scans, ovulation assessment, fertility testing, and personalised treatment planning.
For women with PCOS who are seeking to build a family, NJINSKY IVF & Fertility Clinic also provides fertility treatments including ovulation induction, IUI, IVF, ICSI, and embryo transfer, depending on individual clinical needs.
The clinic’s experienced gynaecologists and fertility specialists focus on evidence-based care tailored to each patient’s specific circumstances.
Understanding PCOS can help women recognise symptoms, seek appropriate medical assessment, and access timely care. PCOS can affect menstruation, fertility, metabolism, skin and hair, and psychological wellbeing, but many women can manage their symptoms and maintain a healthy and fulfilling life with appropriate care.
Whether you are concerned about irregular periods or PCOS-related symptoms, considering a PCOS assessment, experiencing difficulties with conception, or exploring fertility treatment options, speaking with a qualified gynaecologist or fertility specialist can help you understand your options.
Early assessment and appropriate management can support symptom control, reproductive goals, and long-term health.
