- PCOS is a very common and treatable cause of infertility.
- The primary issue in PCOS is irregular or absent ovulation, not an issue with the eggs themselves.
- Lifestyle modifications, particularly achieving a healthy weight, can dramatically improve fertility.
- Effective medical treatments are available to help induce ovulation and achieve pregnancy.
How PCOS Can Affect Your Fertility
Polycystic Ovary Syndrome is a hormonal condition. The key impact on fertility is that it can disrupt the signals that cause you to mature and release an egg each month (ovulation). If you are not ovulating regularly, it becomes much more difficult to time intercourse and conceive.
Many women with PCOS have irregular periods, or no periods at all, which is the main sign that ovulation isn't happening consistently. However, it's important to know that having PCOS does not mean you are infertile; it simply means you may need some support to get things started.
First Steps: Lifestyle and Monitoring
The first and most effective step for many women is focusing on lifestyle. If you are carrying extra weight, even a modest weight loss can be enough to restore regular ovulation and periods. This is because excess weight can affect hormone levels.
We focus on a balanced diet and regular, moderate exercise. It's not about crash dieting, but about sustainable changes that support your overall health and regulate your hormones. We also recommend you start taking folic acid as you would for any planned pregnancy.
Medical Help to Induce Ovulation
If lifestyle changes aren't enough to regulate your cycle, the next step is usually a course of tablets to encourage ovulation. This is known as ovulation induction. In the UK, we typically use medications like Letrozole or Clomifene.
These are taken for a few days at the start of your cycle and work by telling your brain to send stronger signals to your ovaries to grow and release an egg. We often monitor you with ultrasound scans for the first cycle or two to ensure the dose is right and to advise you on the best time to try and conceive. This simple treatment is often very successful.
Frequently asked questions
Do I need to lose weight to get pregnant with PCOS?
Not necessarily, but if you are overweight, losing even a small amount of weight (around 5-10%) can be enough to regulate your menstrual cycle and improve your chances of conceiving naturally. It's often the very first recommendation we make.
Is IVF my only option if I have PCOS?
Absolutely not. For many women with PCOS, the main barrier to conception is irregular ovulation. Simple and safe medications prescribed by a specialist can often help you ovulate regularly, giving you a great chance of conceiving without needing IVF.
What are the first-line treatments for PCOS-related infertility?
After confirming the diagnosis and recommending lifestyle changes, your GP may refer you to a specialist. The first medical treatment offered on the NHS is usually ovulation induction, using tablets like Clomifene or Letrozole to help you release an egg regularly.
Can I track ovulation at home if I have PCOS?
It can be tricky. Ovulation predictor kits (OPKs) often give false positives in women with PCOS due to high baseline levels of Luteinising Hormone (LH). Tracking basal body temperature or cervical mucus can be more reliable, but requires consistency.
