PCOS runs in families. If your mother, sister, or aunt has it, your risk is significantly higher. This isn't coincidence — it's genetics.

Research has identified over 20 genetic regions associated with PCOS risk. These genes are involved in:

• Hormone production and regulation • Insulin signalling pathways • Inflammation • Reproductive development

The heritability of PCOS is estimated at 70% — meaning genetics account for the majority of risk.

But genes aren't destiny. Epigenetics — how genes are expressed in response to environment — also plays a role. Factors like prenatal androgen exposure, stress, diet, and environmental toxins can influence whether PCOS genes are "activated."

This matters emotionally because it means:

• PCOS is not caused by anything you did • It's not the result of poor lifestyle choices • You didn't "give yourself" PCOS by eating the wrong foods or not exercising enough • The condition was written into your biology before you were born

Understanding the genetic basis can help release the shame many people carry. You can manage symptoms effectively, but the underlying predisposition isn't something you caused or could have prevented.
