Endometriosis is a condition where tissue similar to the uterine lining grows outside the uterus, leading to inflammation, scarring, and pain. The condition affects approximately 1 in 10 women. From a fertility perspective, it can impact egg quality and disrupt hormonal balance, which can reduce the chances of conception.  Treatment may involve a combination of medical therapies, surgical interventions, and assisted reproductive technologies to optimise fertility outcomes. Diet, lifestyle and supplement adjustments can also help support those experiencing symptoms.
