Most times people use PCOS (polycystic ovarian syndrome) and PCOD (polycystic ovarian disease) interchangeably. This is because both the conditions are associated with ovaries an integral part of the female reproductive system and show similar symptoms. Every woman has two ovaries which produce female hormones and release one egg each month into the uterus. At times the ovaries can release more than one egg. Apart from producing estrogen or the female hormone the ovaries also produce traces of androgen or testosterone which is the male reproductive hormone. Hormonal imbalances in the ovaries can lead to conditions like PCOS and PCOD.
