**3.3. Reproductive potential**

In PCOS treatment, we aim to restore both normal menstrual function and fertility. In some cases, there may also be a decrease in ovarian volume and a reduction in the number of follicles [30] following weight loss and lifestyle changes. Ovulatory menstrual cycles can be obtained for obese women with PCOS, even when the weight loss is relatively low [31], thus increasing considerably the chances of getting pregnant. However, not all patients equally respond to these measures even if their weight loss is similar [24]. Hollmann et al. describe an 80% improvement in ovulation rate and 29% in the pregnancy rate in the case of a 10% weight loss [32].
