Polycystic ovary syndrome (PCOS) is a condition that affects how your ovaries work. Despite the name, there are no cysts on the ovaries. During ovulation, an egg is released once a month. PCOS can have an impact on this and cause irregular ovulation, or no ovulation at all. If you want to have a family, PCOS can make it difficult to get pregnant.
PCOS can also affect your metabolism (the chemical reactions in the body’s cells that change food into energy) making it easier to gain weight and more difficult to lose weight.
