If you have polycystic ovary syndrome (PCOS), you’re not alone.

Polycystic ovary syndrome: cause and symptoms

Nobody knows for sure what causes PCOS. Most experts think genetics play a role since women with PCOS are more likely to have a mother or sister with PCOS, too. When you have PCOS, your ovaries make more androgens (male hormones) than normal. Because many women with PCOS have too much insulin, which increases production of androgens, experts believe insulin might also play a role.

High levels of androgens affect the development and release of eggs during ovulation. This is why PCOS is a common cause of infertility, which can also be a symptom of the condition. Other symptoms of PCOS may include:

  • Infrequent or irregular periods
  • Increased hair growth
  • Cysts on the ovaries
  • Acne or oily skin
  • Weight gain or obesity
  • Male pattern baldness or thinning hair
  • Dark brown patches of skin on the neck, arms, breasts, or thighs
  • Skin tags, excess flaps of skin in the armpits or neck area
  • Anxiety or depression
  • Sleep apnea, when breathing stops for short periods during sleep
