Can physical activity affect my fertility?

The amount of physical activity that’s recommended for health benefits doesn’t affect your fertility.

In rare cases people who overtrain may stop menstruating. Overtraining can be described as participation in physical activity that lasts for too long, is too intense and is done too often. Participating in this level of physical activity can affect your health.

Overtraining may lead to a negative energy balance. This is when your body needs more energy from food than you’re eating. You can either find ways to eat more healthy foods or change your training schedule. If you have concerns about overtraining, talk with your health care provider.
