oligomenorrhoea

Full Definition

Oligomenorrhoea is a menstrual disorder characterized by infrequent menstruation, with cycles longer than 35 days but less than 90 days apart. This condition can result from various causes including polycystic ovary syndrome (PCOS), thyroid dysfunction, stress, excessive exercise, or hormonal imbalances. It differs from amenorrhoea (absence of menstruation) and may impact fertility. Clinical evaluation typically includes hormonal assessment and pelvic examination to determine the underlying cause and appropriate treatment.
