polycystic ovarian syndrome (PCOS)
PCOS is diagnosed when at least 2 of the following are present: (1) irregular or delayed period
(2)

(3)signs and symptoms of increased levels of
androgens. These are male hormones that are normally found in small quantities in females. The blood values may be increased and there may be hair on the face or chest, acne
There is effective treatment available.
