About one in ten women of childbearing age has PCOS. It can occur in girls as young as 11 years old. PCOS is the most common cause of female infertility (not being able to get pregnant).
Not all women with PCOS share the same symptoms. These are some of the symptoms of PCOS:
* infrequent menstrual periods, no menstrual periods, and/or irregular bleeding
* infertility (not able to get pregnant) because of not ovulating
* increased hair growth on the face, chest, stomach, back, thumbs, or toes—a condition called hirsutism (HER-suh-tiz-um)
* ovarian cysts
* acne, oily skin, or dandruff
* weight gain or obesity, usually carrying extra weight around the waist
* insulin resistance or type 2 diabetes
* high cholesterol
* high blood pressure
* male-pattern baldness or thinning hair
* patches of thickened and dark brown or black skin on the neck, arms, breasts, or thighs
* skin tags, or tiny excess flaps of skin in the armpits or neck area
* pelvic pain
* anxiety or depression due to appearance and/or infertility
* sleep apnea—excessive snoring and times when breathing stops while asleep
