Is cardio actually the key to managing PCOS?

For women with PMOS (PCOS), aerobic exercise helps lower testosterone and LH levels while increasing SHBG. The effect size is modest, but the data shows a measurable shift in hormone profiles.

Test your knowledge

Sarah has polycystic ovary syndrome (PCOS) and is looking for a way to manage her hormone levels through physical activity. If she starts a consistent aerobic exercise routine, what change in her hormone profile is most likely to occur?

A) A significant increase in her testosterone levels to boost energy
B) A major change in her anti-Müllerian hormone levels
C) No measurable change in any of her reproductive hormone markers
D) A significant decrease in her testosterone and luteinising hormone levels

🔬 The Breakdown

Context: This matters because hormonal imbalances in PMOS are often systemic. This research provides a evidence-based foundation for using movement as a tool to regulate androgen markers rather than just a weight-loss strategy.

Reality Check: The study suggests that longer session durations may lead to better LH reduction, but finding the time for consistent, sustained aerobic work can be a hurdle in a demanding schedule.

Takeaway: Incorporate steady-state aerobic movement—like cycling or brisk walking—into your weekly routine to help stabilize your hormone markers.
