Treatment of PCOS (Polycystic Ovary Syndrome)
Polycystic ovary syndrome (PCOS) is a hormonal disorder common among women of reproductive age, causing irregular periods, excess androgen levels, and polycystic ovaries. It is associated with insulin resistance and increased risk of diabetes and heart disease.
Managing PCOS (Polycystic Ovary Syndrome) effectively requires a combination of medical treatment, lifestyle modification, and regular monitoring. With a structured management plan, most people with PCOS (Polycystic Ovary Syndrome) can maintain a good quality of life and prevent serious complications.
First-Line Treatment Principles
- ✓Identify underlying cause: hormonal, structural, tubal, male factor, or unexplained
- ✓Lifestyle optimisation before fertility treatment: weight, smoking, folic acid
- ✓Ovulation induction with clomifene or gonadotrophins for anovulatory infertility
- ✓IVF/ICSI when other approaches have failed or irreversible causes (tubal occlusion, severe male factor)
- ✓HRT for menopausal symptoms: lowest effective dose for shortest duration

- Use our AI symptom checker to assess whether your symptoms fit an early PCOS (Polycystic Ovary Syndrome) pattern
- Discuss preventive strategies and early monitoring with your GP
- Build a personalised management plan with your GP or specialist
- Adhere consistently to prescribed medications — do not stop without medical advice
- Adopt a PCOS (Polycystic Ovary Syndrome)-appropriate diet (anti-inflammatory, low-glycaemic, or disease-specific)
Medications Used in PCOS (Polycystic Ovary Syndrome)
Metformin is a biguanide antidiabetic that reduces hepatic glucose production and improves insulin sensitivity, used as first-line treatment for type 2 diabetes.
Ethinylestradiol is a hormonal agent used for contraception, hormone replacement therapy, or the management of menstrual and gynecological disorders.

Non-Pharmacological Management
- •Weight management: BMI 18.5–25 kg/m² optimises conception rates and reduces obstetric complications
- •Folic acid 400mcg/day: before conception and for 12 weeks in pregnancy (5mg in high-risk)
- •Smoking cessation and alcohol avoidance: improve fertility and reduce miscarriage
- •Regular exercise: moderate-intensity; avoid extreme exercise that suppresses ovulation
- •Stress reduction and psychological support during fertility treatment
- •Pelvic floor physiotherapy: for pelvic pain, prolapse, and urinary incontinence
Treatment Goals
Monitoring Parameters
- ◆Day 21 progesterone: confirm ovulation
- ◆AMH (anti-Müllerian hormone) and antral follicle count: ovarian reserve assessment
- ◆Semen analysis: concentration, motility, morphology — both partners assessed
- ◆Transvaginal ultrasound: follicle monitoring during stimulation cycles
- ◆Endometrial thickness: before embryo transfer (>7mm adequate)
- ◆HCG levels: early pregnancy monitoring; doubling every 48h confirms viable implantation
Red Flags — When to Escalate
- ⚠Any of the characteristic symptoms of PCOS (Polycystic Ovary Syndrome) — even mild — in a high-risk individual
- ⚠Progressive worsening of early warning signs over weeks
- ⚠Laboratory abnormalities (e.g., blood sugar, inflammatory markers) without full symptoms
- ⚠Unexplained weight loss, night sweats, or fatigue persisting >2 weeks
- ⚠Strong family history of PCOS (Polycystic Ovary Syndrome) combined with new relevant symptoms
- ⚠Sudden worsening of PCOS (Polycystic Ovary Syndrome) symptoms despite established treatment
Escalation Criteria
- →Ovarian hyperstimulation syndrome (OHSS): freeze-all embryos if severe; hospitalisation if critical
- →Ectopic pregnancy: urgent surgical or medical (methotrexate) management
- →Recurrent pregnancy loss (≥3): full investigation panel; specialist reproductive medicine referral
- →Endometriosis not responding to medical therapy → laparoscopic surgery consideration
