Can women sync their mensteral cycle?

The idea that women can sync their menstrual cycles, often referred to as the "McClintock effect," suggests that women living together may have their cycles align over time due to pheromonal influences. However, scientific studies on this phenomenon have produced mixed results, and many researchers argue that any perceived synchronization may be coincidental rather than a biological effect. Overall, while some women report experiencing cycle alignment, the evidence supporting this claim is not definitive.
