How does exercise prevent conception?
When our bodies are overworked, overstressed, or constantly moving, they go into a type of physical fight or flight mode. This in turn can impact our natural fertility, as our bodies get the message that it may not be able to support and nourish another little being.
Over-exercise affects both men and women alike. When we stress our bodies and constantly push them ‘to the brink’, our stress hormones (like adrenaline) are activated, sending a cascade of effects that can then inhibit production of the reproductive organs.
In men, extreme workouts such as especially prolonged cardio cause the internal body temperature to rise too high, thus killing off sperm and leading to low sperm counts. This can be especially harmful during workouts where the man sits; rowing or biking.
In women, it can also cause an unnatural loss of body fat. This super lean body type, disrupts the production of estrogen— up to 30% of the body’s estrogen is produced in fat cells. Women with less than 10-15% body fat often fail to ovulate.
