To determine whether a low glycemic index diet is better than a normal glycemic index diet in producing ovulatory cycles in women with polycystic ovary syndrome (PCOS) and anovulation.
A randomized controlled clinical trial involving 37 women with PCOS and anovulation. The authors randomly assigned low glycemic index diets (n = 19) and normal glycemic index (n = 18) diets, and analyzed the number of ovulatory cycles for three months.
In patients who consumed a low glycemic index diet, 24.6% (14/57) of the cycles were ovulatory. In those who consumed a normal glycemic index diet, only 7.4% (4/54) of the cycles were ovulatory (p = 0.014).
The difference observed in the number of ovulatory cycles could be related to a decrease in the serum levels of circulating androgens, secondary to an improvement in insulin resistance.
确定在多囊卵巢综合征（PCOS）和无排卵的女性中，低血糖指数饮食在产生排卵周期方面是否优于正常血糖指数饮食。
一项随机对照临床试验，纳入37例PCOS和无排卵的女性。作者随机分配低血糖指数饮食（n = 19）和正常血糖指数饮食（n = 18），并分析三个月内的排卵周期数。
食用低血糖指数饮食的患者中，24.6%（14/57）的周期有排卵。食用正常血糖指数饮食的患者中，只有7.4%（4/54）的周期有排卵（p = 0.014）。
观察到的排卵周期数差异可能与胰岛素抵抗改善继发的循环雄激素血清水平降低有关。
