Confirm PCOS diagnosis
Ultrasound is one of the Rotterdam criteria for PCOS diagnosis – alongside clinical signs of hyperandrogenism and ovulatory dysfunction. It provides objective, reproducible evidence.
Polycystic Ovary Syndrome (PCOS) is a common hormonal disorder affecting 1 in 10 women of reproductive age. It is characterised by irregular periods, excess androgen levels, and polycystic ovaries on ultrasound. PCOS is a leading cause of infertility, but with accurate diagnosis and appropriate management, women with PCOS can conceive and lead healthy lives.
Ultrasound plays a central role in the diagnosis of PCOS. A transvaginal ultrasound assesses ovarian morphology – looking for the classic "string of pearls" appearance of multiple small follicles (2‑9 mm) arranged around the periphery of the ovary. We also measure ovarian volume and assess endometrial thickness, which can be affected by chronic anovulation.
At Amytri, our PCOS assessment is performed by experienced consultant radiologists using state‑of‑the‑art transvaginal ultrasound. We provide a detailed evaluation of ovarian morphology, follicle count, and ovarian volume, along with endometrial assessment. Our report is interpreted in the context of your clinical history and symptoms, helping your gynaecologist or fertility specialist confirm the diagnosis and plan appropriate treatment.
PCOS is treatable – but accurate diagnosis is the first step. Ultrasound provides the objective evidence needed to confirm the condition and guide treatment.
Ultrasound is one of the Rotterdam criteria for PCOS diagnosis – alongside clinical signs of hyperandrogenism and ovulatory dysfunction. It provides objective, reproducible evidence.
The number and distribution of follicles influences treatment choices – from ovulation induction (clomiphene, letrozole) to IVF. Accurate assessment helps optimise outcomes.
During fertility treatment, ultrasound helps track follicle development and endometrial response – ensuring safe and effective stimulation.
We use a systematic approach to assess ovarian morphology, volume, and other key features of PCOS.
We evaluate the classic PCOS appearance – 12 or more small follicles (2‑9 mm) arranged around the periphery of the ovary, giving a "string of pearls" appearance. This is a key diagnostic sign.
We count the number of follicles (2‑9 mm) in each ovary. An AFC of ≥12 in one or both ovaries is one of the Rotterdam criteria for PCOS.
We measure ovarian volume using the formula for an ellipsoid (L x W x H x 0.523). An ovarian volume >10 ml is consistent with PCOS, especially when combined with other features.
We measure endometrial thickness and assess its pattern. In PCOS, chronic anovulation can lead to a thin endometrium or, if unopposed oestrogen is present, endometrial hyperplasia.
We assess the echogenicity of the ovarian stroma – in PCOS, the stroma is often hyperechoic (bright) and increased in volume.
We rule out ovarian cysts, endometriomas, and other masses that may mimic PCOS or coexist with it.
Your gynaecologist or fertility specialist refers you for a PCOS assessment. We review your clinical history – including menstrual cycles, symptoms, and hormone levels.
We perform a transvaginal ultrasound to assess ovarian morphology, count follicles, measure ovarian volume, and evaluate the endometrium. The scan takes 15‑20 minutes.
We compare the findings to the Rotterdam criteria for PCOS – including AFC, ovarian volume, and morphology. We provide a detailed, actionable report.
We discuss the findings with you and your specialist. If PCOS is confirmed, we discuss next steps – including lifestyle modification, ovulation induction, or fertility treatment.
If you have symptoms of PCOS, or if you are undergoing fertility evaluation, a PCOS assessment can provide essential diagnostic information.
Oligomenorrhea (cycles >35 days) or amenorrhea (no periods) is a hallmark of PCOS – ultrasound can help confirm the diagnosis.
Excess facial or body hair (hirsutism), acne, or male‑pattern hair loss – often accompanied by elevated androgen levels on blood tests.
PCOS is a leading cause of anovulatory infertility – ultrasound assessment is a key part of the fertility work‑up.
Insulin resistance is common in PCOS – if combined with other symptoms, ultrasound can help confirm the diagnosis.
PCOS has a genetic component – if you have a family history, ultrasound assessment is recommended.
High AMH is common in PCOS – ultrasound can confirm the characteristic ovarian appearance.
Dr. Abhishek has extensive experience in gynaecological ultrasound, with a special focus on PCOS and reproductive endocrinology. He is skilled in assessing ovarian morphology, antral follicle counts, and ovarian volume – providing the accurate, reliable information needed for PCOS diagnosis and management.
PCOS assessment is often part of a fertility journey – having your partner with you provides support and shared understanding.
We welcome partners to attend the ultrasound. We explain what we are seeing and how it relates to the diagnosis and treatment plan. Your partner's presence can be especially helpful when discussing fertility implications.
PCOS assessment is a specialised transvaginal ultrasound that evaluates ovarian morphology, antral follicle count, ovarian volume, and endometrial health – providing key evidence for diagnosing Polycystic Ovary Syndrome.
In PCOS, the ovaries typically show 12 or more small follicles (2‑9 mm) arranged around the periphery (string of pearls), often with increased ovarian volume (>10 ml) and hyperechoic stroma.
Transvaginal ultrasound provides the highest resolution images of ovarian morphology and is the preferred method for assessing the features of PCOS. It is a key component of the diagnostic criteria.
The ideal timing is days 2‑5 of the menstrual cycle, when hormonal levels are at baseline. This allows for accurate assessment of ovarian morphology without the influence of ovulation.
Yes, a referral from a gynaecologist or fertility specialist is recommended. They will interpret the results in the context of your clinical history and hormone levels.
After diagnosis, treatment options may include lifestyle modifications (diet and exercise), medications to regulate cycles and reduce androgens, ovulation induction for fertility, and management of metabolic complications like insulin resistance.
