Polycystic Ovarian Syndrome (PCOS) is one of the most common endocrine disorders, affecting approximately 5-10% of women of reproductive age globally. It is a complex condition that spans a woman’s lifespan, from puberty to post-menopause, and affects all ethnic groups.

Common Presentations & Health Risks

PCOS is more than just irregular periods; it affects multiple systems in the body. Common symptoms and associated risks include:

How is PCOS Diagnosed?

At Talwar Fertility, we follow the standard clinical guidelines for diagnosis, which look for three main pillars:

1. Hyperandrogenism: Clinical signs like acne, hirsutism, or scalp hair loss, or biochemical evidence (elevated LH and Testosterone).
2. Polycystic Ovaries (Ultrasound): Identifying 12 or more small follicles (2-9mm) or an ovarian volume > 10mL.
3. Oligomenorrhea: Fewer than 6 to 8 menstrual periods per year.

The Role of Insulin Resistance

Insulin resistance is a state where body cells do not respond effectively to insulin, causing blood glucose levels to rise. This metabolic dysfunction is closely linked to PCOS and can lead to Diabetes Mellitus and Acanthosis Nigricans (darkening of the skin, especially at the neck).

Path to Pregnancy with PCOS

If you are planning a pregnancy, the first goal is achieving successful ovulatory cycles. Strategies include:

• Weight Management: A loss of even 4-5 kg can significantly regularize periods and improve cholesterol levels.
• Insulin-Sensitizing Drugs: These help the body respond to insulin, decreasing androgen levels and restoring ovulation.
• Ovulation Induction: Medications specifically prescribed to help the ovaries release an egg.

Polycystic Ovarian Syndrome (PCOS) is a complex hormonal condition, and Ultrasound remains one of the cornerstone criteria for its diagnosis. At Talwar Fertility & Child Health Centre, we use high-sensitivity Transvaginal Sonography (TVS) to identify polycystic ovaries in approximately 75% of women who present with clinical symptoms of PCOS.

What are Antral Follicles?

Antral follicles are small, fluid-filled sacs in the ovary (measuring 2-9 mm) that contain immature eggs. In a normal menstrual cycle, these follicles grow over 10-12 days until one “dominant” follicle is selected to release an egg. However, in PCOS, this selection process is often disrupted.

Diagnostic Ultrasound Criteria for PCOS

Medical guidelines for PCOS have evolved to become more precise. Here are the key ultrasound markers we look for:

Why Accuracy Matters

Identifying the exact nature of polycystic ovaries helps in tailoring fertility treatments. Whether it is ovulation induction or managing insulin resistance, a clear ultrasound mapping of the ovarian stroma and follicle distribution allows us to predict how your body will respond to medication.
