What are polycystic ovaries?

PCOS - polycystic ovary syndrome is one of the common causes of female infertility, which affects up to 10% of women. It usually occurs in women under the age of 30. Symptoms of this disease include irregular or no menstrual cycle, thinning hair, increased weight or increased facial or body hair. Polycystic ovary syndrome means eggs are not released from the ovaries and remain inside. Therefore, they cannot be fertilised with sperm.
