In women diagnosed with PCOS, the normal functioning of the ovaries is impaired. Ordinarily, the ovaries are expected to produce a single large structure known as a follicle once every menstrual cycle. This follicle grows, producing hormones, and eventually releases an egg during ovulation. However, in PCOS, the ovaries tend to generate numerous small follicles instead of the usual dominant one. As a consequence, hormonal imbalances can occur, leading to irregular ovulation, or in some cases, the absence of ovulation altogether.
