Definition and Pathophysiology
Polycystic ovarian syndrome (PCOS), an endocrine disorder associated with hormonal and cardiometabolic complications, affecting up to 26% of women and those assigned female at birth globally.[1] For the large majority of PCOS patients, the core of their symptoms results from derangements in hyperandrogenism, insulin resistance and inflammation.[2]
Patient Signs and Symptoms
Common clinical signs and symptoms of PCOS include:
- Enlarged ovaries, generally 2-3 times larger than normal, resulting from multiple cysts
- Irregular menstrual cycles – i.e., oligomenorrhoea or amenorrhoea
- Hirsuitism (espcially facial hair)
- Central obesity – "apple-shaped" obesity centred around the lower half of the torso
- Infertility, generally resulting from chronic anovulation (lack of ovulation)
- Androgenic alopecia (male-pattern baldness)
- Jaw-line acne, oily skin, seborrhoea
- Acanthosis nigricans (associated with insulin resistance)
- Sleep apnoea (especially if with metabolic syndrome)
- Blood sugar dysregulation – e.g., hypoglycaemic episodes, diabetes, etc
Risk Factors
Major causative factors and risk factors that can contribute to the incidence of PCOS include:
- Obesity
- Genetics
- Lifestyle
- Diet
- Neuroendocrine alterations (HPO-HPA-HPT axis)
- Gut dysbiosis
- Environmental pollutants.[3]
Screening and Investigations
The International Evidence-based Guideline for the assessment and management of PCOS 2023 indicates diagnosis of PCOS if positive for two out of three following signs:
- Clinical and/or biochemical evidence of hyperandrogenism;
- Evidence of oligo-anovulation; or
- Transvaginal ultrasonographic evidence of a polycystic ovary OR elevated anti-mullerian hormone (AMH) levels.4
For further information on PCOS pathophysiology, risk factors, testing and treatment discussed by key opinion leaders, see on demand webinar Taking the Stress out of PCOS.
Test |
Interpretation |
Follicle Stimulating Hormone (FSH)[5]
|
Evaluate in early follicular phase, day 2 to 6 of menstrual cycle. Elevated FSH levels indicate poor follicle development and consequently, anovulatory cycles. Reduced levels of FSH may indicate hyperprolactinaemia. |
LH:FSH ratio[5] |
The ratio is usually close to 1:1, but if the LH is higher, it is one possible indication of PCOS. Evaluate LH:FSH ratio in early follicular phase between day 2 to 6 of menstrual cycle. |
Anti-Mullerian Hormone (AMH)[4]
|
Can be used as an alternative to transvaginal ultrasound to support a diagnosis of PCOS if levels are elevated. However, it is not to be used as a single diagnostic test on its own. |
Oestradiol (E2)[6]
|
Reduced levels may indicate ovarian abnormalities. Elevation in basal E2 may indicate diminished ovarian reserves secondary to increased early follicular FSH levels. |
Serum Progesterone (P4)[6]
|
Reduced progesterone levels can indicate luteal phase defects and/or anovulatory cycles. Evaluate serum progesterone levels in mid-luteal phase (7 days prior to onset of menses). |
Testosterone[4] |
Recommended to use calculated free testosterone along with calculated free androgen index for superior specificity and sensitivity. |
Oral Glucose Tolerance Test (OGTT)[4] |
Oral glucose tolerance test is most accurate to assess glycemic status in PCOS irrespective of body mass index. |
Oral Glucose Tolerance Test (OGTT) interpretation: blood glucose level (mmol/L)

Treatment recommendations
Core Treatment
Attenuate androgen excess, promote insulin sensitivity and aromatase activity
Inositol, Peony & Liquorice to Clear Testosterone
Acute dose: 2 tablets twice daily Maintenance:2 tablets once daily
- Peony and licorice shown to inhibit androgen and testosterone synthesis.[7,8] Inositol enhances insulin sensitivity whilst supporting FSH and aromatase activity.[9,10]
Promote healthy blood glucose metabolism and insulin signalling.
Magnesium & Inositol to Support Healthy Female Hormonal Balance & Vitality
Dose: 1 serve twice daily
- Magnesium required for insulin synthesis and secretion.[11] Magnesium and chromium required for phosphorylation of insulin receptor required for insulin binding.[11,12] Myo-inositol and chromium required for intracellular insulin signalling and glucose metabolism.[9,12]
Resveratrol Age Well
Dose:1 tablet daily
- Research shows quercetin, resveratrol and curcumin offer anti-oxidant and anti-inflammatory activity whilst supporting mitochondrial activity,13–18 thereby improving glycaemic control and cardiovascular health.[19,20]
Additional Recommendations
To support healthy blood glucose, carbohydrate metabolism and liver function
Indian Barberry and Milk Thistle For Blood Glucose Metabolism and Liver Function Support
Dose:1 tablet twice daily
A blend of berberine, milk thistle and chromium in combination with diet and lifestyle support can help rebalance these patterns of metabolic dysfunction and support PCOS management.[21–24]
To assist in weight loss if necessary The Shake It Practitioner Weight Management Program is a novel 3 phase program structure to:
- Prevent metabolic adaptation
- Reset the patient’s metabolic set point
- Provide regular psychological breaks from active dieting in order to achieve sustained weight loss.
Support progesterone status and corpus luteum health present with lengthened cycles or infertility, also refer to the Amenorrhoea protocol
Vitex, Ginger & Withania to Increase Progesterone
Dose: 1 tablet daily
An herbal and nutritional blend designed to manage the symptoms and causes of progesterone deficiency, working in both the brain and the body to provide effective relief for PMS, painful periods, irregular cycles and infertility.25–27
Address gut dysbiosis associated with PCOS pathophysiology
Choose from Metagenics probiotic range
To support detoxification of environmental pollutants Metagenics Clinical Detoxification Programs designed to support gut health and address the primary source of toxicity in patients. These programs encourage elimination of and protection against these toxins. There are three programs available:
- Health Reset
- Gut Pathogen Elimination
- Liver Chemical Clearance
Promote healthy vaginal ecosystem
Probiotics Lactobacillus rhamnosus (GR-1™) and Lactobacillus reuteri (RC-14™) with liquorice for women’s urogenital health
Dose:1 capsule daily
To promote a healthy vaginal ecosystem L. rhamnosus (GR-1™) and L. reuteri (RC-14™) help to restore lactobacilli levels.28 The addition of vitamin C and vitamin D can also help mitigate UTI symptoms,29,30 promoting local urogenital immune function. Adding further clinical benefits, a deglycyrrhizinated extract of liquorice root (GutGard® liquorice) supports a healthy vaginal mucosa.31
Promote healthy thyroid function
Lycium Hypothyroid support
Loading dose: 2 tablets twice daily with food until improvement, then maintenance dose: 1 tablet twice daily with food
Selenium, iodine, zinc and vitamin A all play important roles in thyroid hormone synthesis, metabolism or activity and optimal thyroid hormone production and receptor function.32–34 In Traditional Chinese medicine and Ayurvedic disciplines, Lycium barbarium is used for fatigue whilst Withania somnifera is an adaptogen and thyroid tonic.[35,36]
Diet and Lifestyle
- Lower intake of refined carbohydrates including sugar, sweets, fruit juices, white breads, pasta and potatoes.
- Regular aerobic exercise (moderate to vigorous) has been shown to improve insulin sensitivity in women with PCOS.
- Manage chronic stress to reduce impact on hypothalamic-pituitary-ovarian (HPO) axis. Further, chronic stress increases HPA axis which further drives insulin secretion.[37]
- Avoid environmental toxins (in food, skin care products, home products), shown to disrupt HPO axis along with glucose metabolism and insulin signalling.[38]
