In Chinese medicine, this condition is often seen as the accumulation of dampness (unresolved fluids in the body) which is caused because the kidney yang energy has become deficient. As the dampness grows, it further weakens the yang, allowing more dampness to form and a vicious circle occurs. Kidney yang can be thought of as a warm, active, motivating energy in the body, and this is vital for good fertility. By tackling both the symptom (the dampness in the cysts themselves) and the underlying cause, the weakness of kidney yang, effective treatment can be made and a combination of acupuncture and herbal medicine is often the most effective method of treatment.
