Polycystic Ovary Syndrome (PCOS) and endometriosis are two distinct gynecological conditions that affect women's reproductive health in very different ways. PCOS is a hormonal disorder characterized by elevated androgen levels, irregular menstrual cycles, and small fluid-filled sacs (cysts) on the ovaries. Endometriosis, on the other hand, occurs when tissue similar to the uterine lining grows outside the uterus, often causing pelvic pain, heavy periods, and fertility challenges. While both conditions can impact fertility and quality of life, their causes, symptoms, and treatments differ significantly.
Because PCOS and endometriosis share overlapping symptoms like pelvic discomfort and menstrual irregularities, self-diagnosis can be misleading, and untreated conditions may worsen over time. Taking a free, instant, online symptom check can help you clarify what your body may be signaling and guide your next steps with confidence before you see a doctor.
