Which condition is characterized by irregular menstrual cycles, hirsutism, and multiple cysts on the ovaries?

The condition that is characterized by irregular menstrual cycles, hirsutism, and multiple cysts on the ovaries is known as Polycystic Ovary Syndrome (PCOS), also referred to as Stein-Leventhal Syndrome. PCOS is a hormonal disorder affecting individuals with ovaries, and it often presents symptoms such as irregular menstrual periods due to hormonal imbalances, excessive hair growth (hirsutism) resulting from elevated androgen levels, and the presence of multiple cysts on the ovaries that can be seen in imaging studies like ultrasounds.

This complex disorder frequently results in various metabolic issues, difficulties with fertility, and can also lead to long-term health conditions like diabetes and heart disease if not managed properly. The combination of these symptoms distinguishes PCOS from the other conditions listed.

Endometriosis primarily involves painful symptoms associated with the presence of endometrial tissue outside the uterus, while ovarian cancer typically presents with more ominous signs and symptoms that do not match the profile of irregular menstrual cycles and hirsutism. Hyperthyroidism relates to thyroid hormone overproduction and can cause irregular menstruation but does not typically involve ovarian cysts or hirsutism as primary features.
