PCOS and Fertility: A Complete Guide to Understanding and Managing Polycystic Ovary Syndrome for Conception
Understanding PCOS and Its Impact on Fertility
Polycystic Ovary Syndrome (PCOS) is the most common endocrine disorder affecting women of reproductive age, impacting approximately 8-13% of women worldwide. PCOS is characterised by irregular or absent ovulation, elevated androgen levels, and polycystic ovaries visible on ultrasound. The good news is that PCOS-related infertility is one of the most treatable forms of female infertility.
How PCOS Affects Hormones and Ovulation

Up to 70% of women with PCOS have insulin resistance, meaning their bodies produce excess insulin. High insulin levels stimulate the ovaries to produce excess testosterone, disrupting the hormonal balance needed for ovulation. Breaking this cycle is the cornerstone of PCOS fertility treatment.
Women with PCOS often have higher LH levels which cause the ovaries to produce more androgens. Follicles develop but do not mature properly, leading to anovulation.
Lifestyle Changes That Make a Difference
Weight management: Even 5-10% weight loss can restore ovulation in many women with PCOS. A 2023 study found that 60% of women who lost 5% of body weight resumed regular ovulation within three months.
Exercise: Combine moderate cardio with strength training. Aim for 150 minutes of moderate activity plus two strength sessions weekly.
Sleep: Women with PCOS are at higher risk for sleep disorders. Prioritise 7-9 hours of quality sleep.
The PCOS Fertility Diet
A low-glycaemic Mediterranean diet is most effective. Choose whole grains, legumes, and vegetables. Eat fatty fish, olive oil, and anti-inflammatory foods. Pair carbs with protein and fat to blunt blood sugar spikes. Reduce sugar, refined carbs, and processed foods.
Targeted Supplements for PCOS
Myo-Inositol: The most researched supplement for PCOS. Improves ovulation rates by 60%. The therapeutic dose is 2-4 grams daily.
Vitamin D: Up to 85% of women with PCOS have low levels. Supplementation improves insulin sensitivity.
Omega-3s: Reduces androgen levels and improves metabolic health. Aim for 1000-2000mg daily.
Berberine: Works similarly to metformin for improving ovulation. Consult your doctor before taking.
Medical Treatments
When lifestyle changes are not enough: Clomiphene citrate induces ovulation in 70-80% of women. Letrozole may be superior for PCOS. Metformin helps restore ovulation. IVF is recommended when other treatments fail.
