A meta-analysis of 1,044 women with Polycystic Ovary Syndrome (PCOS) looked at how exercise alone affects reproductive, endocrine, and metabolic health. The study found that exercise significantly reduced total and free testosterone levels. It also helped lower fasting insulin and markers of insulin resistance, while increasing healthy cholesterol levels.
Some results were more noticeable depending on specific factors. For example, women who exercised for at least 150 minutes per week saw more significant drops in total testosterone. Additionally, moderate to low intensity exercise was linked to higher levels of sex hormone-binding globulin. The study also noted that certain groups, such as Asian and South American populations, saw specific benefits in testosterone and insulin levels.
While the results are promising, the impact of exercise can vary based on a person's body mass and specific demographics. Because everyone's body reacts differently, these findings show a general trend rather than a guaranteed outcome for every individual. Talk with your doctor to determine the best exercise plan for your specific needs.
